• Deployment of Emotion-Recognition Technologies in China Threatens Human Rights

    Emotion recognition is a biometric technology which purports to be able to analyze a person’s inner emotional state. These biometric applications are used by law enforcement authorities to identify suspicious individuals, and by schools to monitor how well a student is paying attention in class. China is deploying the technology to allow the authorities to better monitor forbidden anti-regime thoughts among citizens who are subject to police interrogation or investigation.

  • Swarming Drones Concept Flies Closer to Reality

    A swarm of twenty drones has recently completed the largest collaborative, military-focused evaluation of swarming uncrewed aerial vehicles (UAVs) in the U.K. The exercise was the culmination of the Defense Science and Technology Laboratory’s (DSTL) “Many Drones Make Light Work” competition

  • Robot Seeks Out Chemical Agents

    Scientists have successfully tested a fully autonomous robot that will help defense and security personnel dealing with hazardous scenes. The development of the robot means that humans and machines can now share the burden of detecting and report dangerous chemicals over large areas.

  • Baltimore Aerial Investigations Associated with Small Improvements in Solving Crimes

    A preliminary report about an effort to use aerial surveillance to aid police investigations in Baltimore finds that the effort was associated with small increases in the rate at which police solved serious crimes, but an overall evaluation of the program will require a wider review of citywide police efforts, according to a new report.

  • Face Surveillance and the Capitol Attack

    After last week’s violent attack on the Capitol, law enforcement is working overtime to identify the perpetrators. This is critical to accountability for the attempted insurrection. Law enforcement has many, many tools at their disposal to do this, especially given the very public nature of most of the organizing. But the Electronic Frontier Foundations (EFF) says it objects to one method reportedly being used to determine who was involved: law enforcement using facial recognition technologies to compare photos of unidentified individuals from the Capitol attack to databases of photos of known individuals. “There are just too many risks and problems in this approach, both technically and legally, to justify its use,” the EFF says.

  • Identity Verification in the Age of COVID-19

    Face masks have become a way of life due to the COVID-19 pandemic. We now wear them nearly everywhere we go—at grocery stores, on public transportation, in schools, at work—any situation that requires us to be around others. But what about at places that require a higher level of security, like airports?

  • K9 Chemistry: A Safer Way to Train Detection Dogs

    Trained dogs are incredible chemical sensors, far better at detecting explosives, narcotics and other substances than even the most advanced technological device. But one challenge is that dogs have to be trained, and training them with real hazardous substances can be inconvenient and dangerous.

  • Face Recognition Software Improving in Recognizing Masked Faces

    A new study of face recognition technology created after the onset of the COVID-19 pandemic shows that some software developers have made demonstrable progress at recognizing masked faces.

  • EFF Urges Federal Appeals Court to Rehear Case Involving Unconstitutional Baltimore Aerial Surveillance Program

    In May, the Baltimore Police Department launched its Aerial Investigation Research (AIR) Pilot Program. For six months, three surveillance aircrafts operated by a private company called Persistent Surveillance Systems flew over Baltimore—covering about 90 percent of the city—for 12 hours every day. The planes produced images that even at a resolution of “one pixel per person” allowed the police to track individual’s movements over multi-day periods, especially when combined with the police’s networks of more than 800 ground-based surveillance cameras and automated license plate readers.

  • Banning Chokeholds

    George Floyd’s murder was egregious but not unique. Many police agencies hold the position that they don’t train officers to use chokeholds, but they are continuously used by officers to regain compliance. Abrief just released by the Center for Justice Research (CJR) at Texas Southern University offers comprehensive recommendations for key stakeholders, at all levels, to consider in the advancement of police reform in their respective jurisdictions.

  • New Body Armor Offers Better Knife Protection

    The number of knife attacks in Britain has increased over the past few years, while police officers and correctional personnel must contend with an increasing threat from makeshift weapons, such as shanks and spikes. PPSS Group the other day announced a replacement for their polycarbonate-based stab resistant body armor. According to company CEO Robert Kaiser, the new body armor is lighter, thinner, more effective, and more functional.

  • NSA’s Post-9/11 Mass Surveillance Program, Exposed by Snowden, Illegal: Court

    The U.S. Court of Appeals for the Ninth Circuit has ruled that the National Security Agency (NSA) intelligence’s surveillance program exposed by whistleblower Edward Snowden was unlawful, and possibly unconstitutional. Critics of the program say that in addition to violating privacy rights, the program’s was ineffective: Billions of phone calls and email messages were collected and scanned over the years, but only a handful of terrorism suspects were seized, and even fewer were convicted.

  • Antifa Protester Suspected of Killing Trump Supporter in Oregon

    For the first time, a self-identified member of the militant movement known as antifa has been implicated in a fatal shooting and is reportedly under investigation in the killing of a supporter of President Donald Trump on Saturday in Portland, Oregon. If Reinoehl is implicated in the case, it would mark the first time in recent years that an antifa supporter has been charged with homicide, said Brian Levin, an expert on terrorism and extremist movements. Gary LaFree, a University of Maryland criminologist, says “We’re getting these situations where people with opposing perspectives are going in as volunteers” to enforce their views in violent ways, while the police “are not exactly sure what to do in this circumstance,” he said. “I think it’s going to be inevitable if you keep having situations like this, things are going to get out of hand.”

  • Chemical Fingerprint for Explosives in Forensic Research

    The police frequently encounter explosives in their forensic investigations related to criminal and terrorist activities. Chemical analysis of explosives can yield valuable tactical information for police and counterterrorist units.

  • Next-Generation Explosives Trace Detection Technology

    Explosive materials pose a threat whether they are used by domestic bad actors or in a theater of war. Staying ahead of our adversaries is a job that DHS DOD share. The two departments’ research and development work is no different.
