The country needs to find a “compromise” between privacy and safety, according to Flock Safety CEO Garrett Langley. “When people talk about just one of these, privacy or safety, they’re prioritizing the wrong thing, and what we have to prioritize as a country is compromise,” Langley said during a recent interview with Fox News. “How do we have our safety, and how do we balance privacy?” Langley’s Fox News appearance was just the latest interview he’s given as the company faces a growing public outcry around concerns that Flock’s surveillance cameras, drones, and license plate recognition technology could be misused. These concerns aren’t just hypothetical. The Washington Post recently identified 46 cases where police officers have been accused of using Flock technology for unauthorized purposes, including to stalk their wives, girlfriends, or exes. After listening to an interview with one of the alleged victims, Langley told CBS News, “I apologize. It kills me that she went through that.” At the same time, he insisted, “I don’t think that Flock created police abuse. I think we’re the first company to ever shine a light on it and build the tools to find it.” Just as the data center backlash has become a potent issue on both the left and the right, both Democratic and Republican politicians have begun to take aim at Flock. On the left, Michigan’s Democratic Senate nominee Abdul El-Sayed recently accused his opponent Mike Rogers of supporting “this mass proliferation of Flock cameras, any and everywhere, watching your every move to collect information without you even noticing.” And Vermont Senator Bernie Sanders posted, “STOP AI MASS SURVEILLANCE. STOP FLOCK.” On the right, three House Republicans recently introduced a bill that would prohibit the federal government from purchasing automated surveillance systems that use facial recognition, biometric IDs, or license

China is driving a major evolution in the Asia Pacific's pet industry, shifting from basic manufacturing to advanced, AI-powered smart pet care, as showcased at Pet Fair Asia 2026 held in Shanghai from Wednesday to Sunday. Featured products included facial-recognition feeders, health-tracking litter boxes, and remote monitoring devices -- innovations increasingly embraced by tech-savvy younger generations to manage their pets' wellness. "Our intelligent system leverages AI algorithms for cat facial recognition and provides tailored daily feeding recommendations by using data on the cat's eating habits and how many grams of food it eats. Such smart devices significantly lower the barrier to cat ownership, perfectly meeting the current demand among young people for science-based pet care," said Chen Hongshang, product design manager at the Shanghai Lianchong Intelligent Technology Co., Ltd, a leading smart pet care brand in China. According to the 2026 China Pet Industry White Paper, China's urban pet population reached 126 million in 2025, fueling a pet consumption market worth 312.6 billion yuan (about 45.4 billion U.S. dollars). The market is expected to expand further to 405 billion yuan by 2028. This year's fair is the largest since it was launched in 1997. It gathered over 2,600 exhibitors from around the world to present their latest products and services across 17 indoor and 10 outdoor halls covering a combined area of 320,000 square meters. The event has drawn over 500,000 visitors since its opening day. Pet Fair Asia 2026 spotlights China's cutting-edge innovations for pet industry Canadian businesses are adapting to the impact of the trade dispute with the United States, with many trying to reduce their dependence on American imports and diversify their suppliers. The United States imposed a 50-percent tariff on 20 billion U.S. dollars' worth of Canadian goods on Saturday that came into effect just after

A police officer uses the Flock Safety license plate reader system. Many left-leaning states and cities are trying to protect their residents' personal information amid the Trump administration's immigration crackdown, but a growing number of conservative lawmakers also want to curb the use of surveillance technologies. Mohave County Attorney Matt Smith told county supervisors that the Sheriff’s Office’s use of Flock traffic cameras complies with current constitutional protections, while acknowledging that broader tracking or future facial-recognition capabilities could raise different legal questions. Smith presented his office’s legal assessment to the Mohave County Board of Supervisors last week after members of the public raised questions about the cameras and their constitutionality with at least one supervisor. County Attorney Matt Smith got it right. The Board should quit treating license-plate cameras like a secret-police plot. These readers photograph license plates on public roads. That is not a bedroom or a phone in your pocket. It is a number the state already requires you to display. Smith’s office reviewed the law and said the Sheriff’s current use — no facial recognition, no round-the-clock tracking of regular drivers, and logged access for real investigations — meets the Constitution. That is the County Attorney’s job. He did it. Supervisor Gould’s “surveillance state” line sounds dictatorial until you read Smith’s limits: deputies are not watching every car, the system is not stalking people across the country, and the data is not a free-for-all. Courts have treated public-road license plate hits as legal. They have also said the analysis can change if government compiles long travel histories or adds face-ID. Smith said that out loud. That is an honest legal line, not a cover-up. Want accountability? Audit the logins. Punish misuse. Keep vendors from selling the data. Arizona already moved on third-party sharing. None of that requires

According to the Japan Times, the development of artificial intelligence (AI) is making this technology increasingly accurate. As recognition capabilities improve, facial recognition could become a quick authentication method, reducing the need to carry cash, bank cards, or mobile phones. From the shop to the train station One clear application is cashless payments in stores. Trial Holdings, a company that operates a chain of discount stores and various other businesses, has introduced facial recognition payment services from NEC Corporation ( Japan ) into 15 stores in Tokyo and Fukuoka Prefecture. This is the world's leading biometric system, notable for its extremely high accuracy, fast processing speed, and ability to recognize individuals even when wearing masks. After pre-registering, customers can shop and pay at the self-service counter without using cash or mobile payment services. The process, which previously required cards, wallets, or smartphones, is now streamlined into a quick and convenient facial recognition authentication step. This technology is also being tested in the transportation sector. Hitachi and Tobu Railway have installed facial recognition ticket gates at Ikebukuro Station and several other stations on the Tojo Line. In the future, this method is expected to expand to payments at commercial establishments, including convenience stores near train stations. At Tokyo Dome, baseball fans can enter the stadium to watch Yomiuri Giants games through Panasonic Connect's facial recognition system after registering their ID. Some shops inside the stadium also allow cashless payments without bank cards. Thus, facial recognition is creating a fairly seamless ecosystem, from transportation and shopping to entertainment. Users can perform many activities without constantly taking out their documents, cards, or phones from their pockets. Data security problem The value of this technology doesn't lie in helping people "avoid carrying wallets." Facial recognition can also help reduce waiting times, limit the use

Glasgow must copy New York as former beat cop shocked at open criminality in wake of BBC documentary EXCLUSIVE: David Kennedy, general secretary of the Scottish Police Federation, has dismissed suggestions a recent Disclosure episode was unduly harsh on Scotland's biggest city A former police officer who spent years on the beat in Glasgow has said the depiction of the city in a recent BBC documentary was accurate, as he called on city bosses to learn from New York. David Kennedy, who is now general secretary of the Scottish Police Federation, said he counted five arrestable offences in a short walk down Union Street during a trip to the city centre this week. The lack of officers patrolling the streets had left the city a pale shadow of its former self, he suggested. It comes after the Disclosure episode shone a light on drug taking, violence and other anti-social behaviour after film crews spent a week recording there in June, leading to claims the city had become "lawless". The episode has been blasted by Scottish nationalists but Mr Kennedy told the Scottish Express that the scenes filmed were familiar to rank-and-file officers. He said claims that statistics show crime was down in the city didn't "show the full picture," adding: "What shows a true picture is when you look in walking the streets. "I was in Union Street in Glasgow at half past 11 in the morning on Monday, and I saw at least five people who, if I had been in uniform, they would have probably been arrested and given the jail. I was a cop on the beat in Glasgow and I would have absolutely went up, spoke to them, went over and dealt with them." Asked what they were doing, he replied: "Shouting, swearing, obstructing the pavement.

Officers investigating the theft of a shopper’s phone from a store want to track down this man. The victim was targeted in the Wollaton Co-op after she stopped at the till to pay for her items. Having put her phone on the side, the woman left the shop in Lambourne Drive without remembering to pick it back up again. Realising her mistake, she went back into the store, by which time the phone was nowhere to be seen, so she informed shop staff. Having reviewed available CCTV, shopworkers saw that an unknown man had spotted the phone next to the till, pocketed it, and left the store. The theft took place around 7.05pm on 14 July, with the police launching an investigation after being notified soon after. Officers can now release this picture of a man they’d like to speak to as part of their inquiries. PC Kevin Kirk, of Nottinghamshire Police, said: “This incident was sadly an example of how opportunistic thieves can be. “Having spotted a phone left at the till, the person responsible didn’t do the honourable thing and hand it in but instead chose to steal it. “The victim was understandably left very upset by what happened, so we’re determined to try and return their stolen property to them. “On that note, we’d ask that the man pictured does the right thing and makes themselves known to us, as we believe they may be able to assist with our investigation. “Likewise, we’d ask anyone who recognises them to share this information too.” The police can be contacted directly on 101, quoting incident 732 of 14 July 2026, while Crimestoppers can be called anonymously on 0800 555 111.

Mark Zuckerberg’s Meta has never just come out and said that its overarching goal as a company is to boil every last ounce of joy out of the basic experience of being a social animal, but the “boil-joy-and-suck” aspects of their business plans are easy to infer. Even beyond *gestures vaguely, but emphatically, at the last 20 years of online life*, it’s hard not to look at the company’s most recent patent—which would allow the AI-assisted facial accessory the company would really like people to stop calling “pervert glasses” to analyze all of your interactions with friends and loved ones, run them through facial recognition software and other analysis, and then feed you a “highlight reel” of your own life—and not think, “Oh, this was made by people who don’t think too much of the whole human experience, huh?” Per 404 Media, Meta filed the patent for “Smart Cameras Enabled By Assistant Systems” back in February, before it was published last week. In essence, the patent would allow users of Meta’s allegedly smart glasses to turn the whole world into Facebook: Your glasses would record the people around you, tag them, identify when they do things, and then later use that information to present you with a social media-style automatically generated slideshow of things you’d already lived through. (The company’s language repeatedly uses a dinner party as the event our hypothetical memory-deficient voyeur would be ruining.) Besides its obvious and horrifying applications for things like police surveillance and other Flock-esque attempts to shove ever larger portions of the world into monitored cameras—because we’re pretty sure the facial recognition and action-tagging aspects of these things aren’t going to stop at, say, “passing that really good cab sav Michael picked up in Tuscany last fall”—the patent itself is also a potent psychological

At a liquor store, bar, or casino, getting carded is part of the cost of entry. Now the Internet is carding people, too – and the companies doing the carding are cashing in. New laws and platform rules are pushing games, social platforms, AI products, and adult sites to replace birthday boxes (the fields where you enter your date of birth) with identity checks. What was once a compliance tool for sellers in age-restricted industries is becoming infrastructure for the Internet, and a growth market for the companies supplying it. Socure, a Nevada-based identity-verification company founded in 2012, says it now generates more than US$340mil (RM1.39bil) in annual recurring revenue from over 3,000 customers. New ARR (annual recurring revenue) grew 62% year over year, and age verification is among its fastest-growing product lines. The roughly 500-person company has raised approximately US$646mil (RM2.64bil) in private funding. London-based Yoti, founded in 2014 by Robin Tombs, 57, and Noel Hayden, 55, says it has completed more than one billion age checks for roughly half a billion people. Its revenue rose 62% in 2025 and reached roughly US$43mil (RM175.91mil) in the year ended March 2026. And San Francisco identity startup Persona, founded in 2018 by Rick Song, 35, and Charles Yeh, 33, raised US$200mil (RM818.20mil) at a US$2bil (RM8.18bil) valuation in April 2025. The roughly 700-person company has raised about US$418mil (RM1.71bil) to date, and its annual recurring revenue surpassed US$100mil (RM409.10mil) in 2025, according to a Forbes estimate. Age assurance is one use-case within its broader identity-verification business; Persona works with businesses including Roblox, OpenAI, Coursera, and Lime. All three are benefiting from the same shift: Businesses increasingly need to know not just who a user is, but how old they are and which parts of their platform they should be allowed to

This post was co-authored with Max Silfverberg (Data Scientist, AI Solutions Lead), Antti Hallavo (Lead AI Software Engineer), and Pontus Huotari (Lead Data Scientist). We work at Alma Media, a Finnish digital services, marketplaces and media company. One of our focus areas is developing AI/ML solutions for real estate listing services, where understanding image content plays an important role. Our solution is to automatically tag photos with room-type and content classes. Our room types include LIVING ROOM, KITCHEN, and BEDROOM. We also tag schematic content like floor plans and site plans. Additionally, we recognize realtor marketing materials, aerial shots, and garden photos. Altogether, there are 23 classes. As Figure 1 shows, this is a classic multi-label classification task; the same space can encompass several room types at once. On the face of it, this sounds simple, but we need to make some tricky decisions. How should you treat a living room photo that shows a bedroom through a doorway? What if the photo only shows 10% living room and the remaining 90% is dining area? The answers depend on the application. If we need to find all photos showing kitchens, we also want to identify living room photos that show a kitchen in the background. However, if the user specifically asks for kitchen photos, we only want to show the ones where the kitchen is in focus. To help decide what to return, classification confidence is important. But depending on how you implement your classifier, you might not have access to that information. Image classifiers can be built in many ways. The modern default approach is to run images through a third-party API which internally uses a vision-language model (VLM) to analyze images and generate tags according to a prompt. Another option is to train image classifiers on top of

Legal Wrongly Arrested Peppermill Casino Guest Seeks Names of 168 Others Flagged by Facial Recognition Posted on: August 21, 2026, 01:44h. Last updated on: August 21, 2026, 01:50h. A Nevada man who was wrongly arrested after being misidentified by facial recognition technology at Reno’s Peppermill Casino Resort is seeking the identities of 168 other people who were allegedly flagged by the system. Jason Killinger has asked a federal judge to order the City of Reno to produce unredacted arrest reports and declarations of probable cause involving individuals identified by Peppermill’s facial recognition software. The request forms part of Killinger’s lawsuit against Reno and police officer Richard Jager over his September 2023 arrest. Nightmare Ordeal Truck driver Killinger was flagged as a “100% match” to an individual named Michael Ellis who had been banned from the venue months earlier for sleeping on the premises. Despite Killinger’s insistence that he had been misidentified, Jager refused to believe he was who he claimed to be and accused him of using fraudulent identification when he produced a valid Nevada Real ID, Peppermill player’s card, and debit card in his name. Jager chose to trust in the powers of facial recognition software over material facts, such as that Killinger is four inches taller than his doppelganger and has blue eyes rather than hazel. Killinger was jailed for nearly nine hours and spent more than three hours in handcuffs, which left him with bruising and shoulder pain, according to the lawsuit. The lawsuit alleges that even after a fingerprint check at the Washoe County jail confirmed Killinger’s true identity, Jager filed a police report claiming Killinger had presented conflicting identification to Peppermill security. After settling out of court with Peppermill, Killinger sued Jager and later added the City of Reno, alleging the city failed to properly

Amnesty International on Wednesday accused Argentina of building techno-authoritarian surveillance infrastructure without adequate legal safeguards, as the government’s newly created AI security unit expands state monitoring powers over citizens’ online communications and physical movements. In its latest report, the rights group stated that Argentina‘s Ministry of Security spent at least USD$1.2 million on surveillance technology between 2024 and 2025, which included social media monitoring tools, facial recognition software, and thermal-camera drones with automatic tracking and ability to transmit images in real time. Amnesty expressed concern for the surveillance of protesters, journalists, activists, human rights defenders, migrants, young people, and marginalized groups. They warn that this can create a “chilling effect,” in which people who believe they are being monitored may avoid speaking, protesting or organizing, even without being directly arrested or punished. This raises concerns about the impact of surveillance on the right to freedom of expression, freedom of peaceful assembly, and freedom of association. In October 2025, Argentina bought a Clearview AI facial recognition license for USD$33,500. Clearview’s database contains more than 70 billion facial images scraped from the internet, and data protection authorities in France, Italy, Greece, and the Netherlands have already fined the company over its data practices. The Ministry, however, maintains that the Federal Police use facial recognition only in connection with active judicial investigations, and no evidence has surfaced that Clearview was used specifically to identify protesters. Argentina’s expansion of AI-driven surveillance has largely occurred through executive and ministerial measures. On July 26, 2024, then-Security Minister Patricia Bullrich signed Resolution 710/2024, creating the Artificial Intelligence Unit Applied to Security (UIAAS) inside the Ministry of Security’s Directorate of Cybercrime and Cyber Affairs. The resolution authorizes the unit to patrol open social media, applications, websites, and the dark web, and permits real-time facial recognition through CCTV footage,

Nottinghamshire Police deployed live facial recognition technology in Nottingham city centre for the first time today, Friday 21 August.
The marked police van, equipped with a 360-degree dual-camera system, was stationed in Old Market Square as officers monitored the surrounding area.
The cameras scan the faces of people passing the vehicle and compare them with a police watchlist containing images of individuals suspected of serious offences or wanted for safeguarding reasons.

When the system identifies a potential match, an alert is sent to officers, who must review it and decide whether to approach the person. Police say scans that do not produce a match are deleted within seconds and are not retained.
Signs were displayed around the deployment area informing members of the public that the technology was operating.
The launch follows the force’s announcement in July that facial recognition camera vans would be deployed across Nottinghamshire.
The Wire captured this video and pictures of the technology operating in Old Market Square during its first deployment.

From Fuzozo to Pophie: What AI Companion Devices Teach Us About Building the Next Generation of IoT Products Lawrence Wu Lawrence Wu For decades, connected devices have been built around commands. A user presses a button. A sensor reports a reading. A mobile app sends an instruction. Even voice assistants largely followed the same pattern by waiting for a wake word before processing a request. A new generation of AI-native devices is changing that interaction model. Products like AI companions, consumer robots, assistive technologies, educational devices, and wellness products are expected to hold natural conversations, remember previous interactions, recognize different users, respond emotionally, and stay available throughout the day. Instead of reacting to isolated commands, they participate in continuous interactions. That seemingly small shift fundamentally changes the engineering requirements behind the device. Building these experiences is no longer just about integrating a language model. Developers must solve a new class of real-time systems problems involving latency, speech recognition, interruption handling, identity, memory, synchronization, and global infrastructure. Two recent products illustrate this particularly well: Robopoet's Fuzozo and InsBotics' Pophie. Although they target different audiences, they reveal a broader lesson about where IoT architecture is heading. When users are speaking naturally, every pause becomes noticeable. Conversations involve overlapping speech, interruptions, changing speakers, emotional tone, background noise, and long-running context. Unlike issuing a command to a device, conversation is continuous and highly sensitive to timing. The engineering challenge shifts from transmitting data efficiently to maintaining a believable interaction. Instead of optimizing only network throughput or cloud connectivity, developers must optimize something much harder: the flow of human conversation. Most engineers understand that lower latency improves responsiveness. For conversational devices, latency affects something deeper. It shapes whether an interaction feels natural. People instinctively expect conversations to flow without awkward pauses. Delays that might be

Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*). Lightweight neural networks are increasingly used for image classification in scenarios where memory, computation, and energy resources are limited. However, reducing model size often results in a noticeable loss of robustness and generalization, as compact architectures struggle to learn fine-grained structural cues such as edges, textures, and high-frequency patterns. This limitation is especially evident in domains like medical imaging, microscopy, and remote sensing, where subtle spatial variations play an important role in discrimination. In this work, we introduce LiFGANet, a lightweight frequency and gradient aware network designed to mitigate this problem by incorporating explicit inductive biases into feature learning. Instead of increasing model capacity, LiFGANet emphasizes structurally informative representations through an efficient frequency gradient interaction mechanism, combined with sparse feature refinement and multi-stage feature aggregation. The proposed design remains compact, with approximately 1.13M parameters, and introduces negligible inference overhead. We evaluate LiFGANet on PneumoniaMNIST, BloodMNIST, FashionMNIST, and EuroSAT. The results show consistent and well-balanced performance across datasets surpassing state-of-the-art lightweight models with similar or larger parameter budgets. Ablation studies further demonstrate the various advantages of frequency guidance and gradient modulation. The code and implementation details are available on GitHub.

Debate sparks among residents in Town of Irmo about flock cameras IRMO, S.C. (WACH) — Some new traffic cameras in the Town of Irmo are causing a bit of controversy for some people who live there. The cameras are making a noticeable presence in the town, as well as across the state. "If it's being used for other means, you know, following people or things outside of that, I really don't see a use for it," David Cope, Lexington County resident, said. Town residents have been showing mixed emotions after Irmo officials announced plans to install over 20 new flock cameras. RELATED | Irmo officials address online misinformation after safety camera expansion "This place is pretty mellow, but lets keep it that way," Robert Aguilera, Town of Irmo resident, said. According to the Town of Irmo website, the cameras are strictly to be used as investigative tools to help law enforcement. The cameras take a picture of the rear of a car to read the license plate, and do not use facial recognition technology. Town councilmember Gabriel Penfield is the only town council chairholder who opposes the additional flock cameras. "We have a level population, we have a fully staffed police department, so I was just very curious of the need for identification came from," Penfield said. The Midlands have seen flock cameras cause issues over the last month, Including two cameras in Irmo being vandalized last week and a former Richland County deputy being arrested after misusing the camera system. Penfield says he agrees with the people who call these cameras an invasion of privacy. "It is a lack of consent for having that information collected and then ultimately stored in public company servers," Penfield said. Stephen Miano, owner of that computer store, says after the cameras collect a

Abstract Neuromorphic vision functionalities have been realized by coupling quasi-bound states in the continuum (quasi-BICs) to multiple quantum wells (MQWs). The engineered leaky modes enhance infrared absorption and generate coexisting nonlinear and linear photoresponses that support image preprocessing and in-sensor computing. This approach highlights a new role for quasi-BIC leakage in integrated optoelectronic intelligence. Biological vision systems perform substantial information processing before signals reach the brain1. Within the retina, operations such as contrast enhancement, noise suppression and feature extraction are executed locally, reducing the computational burden of higher visual centers and enabling highly efficient perception. Reproducing such front-end processing capabilities in artificial hardware has become a central objective of neuromorphic vision technologies, which seek to overcome the latency and energy costs associated with conventional von Neumann architectures where sensing and computation are physically separated2,3. Among various optoelectronic platforms, multiple quantum wells (MQWs) provide a promising route for infrared neuromorphic vision systems due to their strong quantum confinement effects, fast carrier dynamics, and compatibility with mature semiconductor fabrication technologies4,5,6,7. These structures have been widely explored in infrared imaging, optical communication, and sensing applications, making them attractive candidates for in-sensor visual processing8,9,10. However, the optical response of MQWs is fundamentally governed by intersubband selection rules, which require a dominant out-of-plane electric-field component to efficiently drive carrier transitions11,12. As a result, the absorption efficiency under normal incidence is intrinsically limited, posing a critical challenge for direct integration into compact imaging systems. To overcome this limitation, a variety of photonic coupling strategies have been explored. Metallic gratings were introduced to provide the required out-of-plane electric-field component under normal incidence13, while plasmonic resonators14 and metamaterial absorbers15 were subsequently employed to enhance local electromagnetic fields and improve detector responsivity. More recently, metasurfaces have emerged as a versatile platform for tailoring light–matter interactions in MQWs through engineered

India appears to be normalising the technical ability to subject political gatherings to searchable biometric surveillance without first having settled, through legislation and judicial oversight, the circumstances in which the state may lawfully do so. While the Delhi Police have continued to deny the use of excessive force and manhandling people involved in the Cockroach Janta Party protests, contrary to protestors’ testimonies, facial recognition equipment was present at the protest site while the demonstrations were on. According to its affidavit to the Supreme Court of India, the police deployed a facial recognition system (including Artificial Intelligence-enabled cameras to scan faces in real-time against a database), a mobile surveillance van and a command and control vehicle, smart spectacles for identifying individuals on the move, and drones and videographers; the van and the spectacles have been tied to private contractors. The police have also not addressed whether actual biometric processing occurred with every individual within the range of cameras. Even if the police discarded the images associated with infructuous checks, that the data may have been accessible to private contractors, whose terms of engagement are unclear, is worrisome. However, no statute governs the use of facial recognition systems; the Digital Personal Data Protection Act, whose data-processing obligations are not yet in force, still makes broad exemptions for state agencies. The Automated Facial Recognition System of the National Crime Records Bureau can be used to identify criminals, unidentified bodies, and so on, and the Criminal Procedure (Identification) Act 2022 expanded the set of records that the police may collect from specified persons. However, these actions are still only allowed vis-à-vis specific groups of people. Irrespective of the constitutional validity of the police’s actions, the chilling effect on potential participants may also curtail the right to protest. The state has to pass a well-established
