• Gathering information from smartphones in crime investigations

    Researchers are working on a new technique that could aid law enforcement in gathering data from smart phones when investigating crimes. The technique, called RetroScope was developed in the last nine months as a continuation of the team’s work in smart phone memory forensics. The new approach moves the focus from a smart phone’s hard drive, which holds information after the phone is shut down, to the device’s RAM, which is volatile memory.

  • Germany to search refugees' phones to establish identity, spot suspicious connections

    German interior minister Thomas de Maizière will next week announce a new German anti-terror steps, which, among other things, will require refugees and asylum-seekers arriving in Germany without a passport to surrender their smartphones – and all the passwords and security pin numbers associated with the phones – so German security agencies could check the owners’ social media accounts. The security services in Denmark, Norway, Sweden, and the Netherlands already routinely examine refugees’ mobile phones to establish a refugee’s identity.

  • “Liquid fingerprinting” technique identifies unknown liquids instantly

    A new company — Validere — will commercialize sensing technology invented at Harvard University that can perform instant, in-field characterization of the chemical make-up and material properties of unknown liquids. Validere aims to develop the licensed technology, called Watermark Ink (W-INK), into a pocket-sized device that could be used by first responders to quickly identify chemical spills, or by officials to verify the fuel grade of gasoline right at the pump.

  • Accessing a murder victim’s fingerprint-protected smartphone to help solve a crime

    Last month, when the Michigan State University Police Department approached professor Anil Jain to see if he could access a fingerprint-locked deceased man’s smartphone to aid in a police investigation, Jain accepted the scientific challenge. On Monday, 25vJuly, it was mission accomplished – Jain and his team unlocked the phone.

  • Swimming, crawling, climbing robot to help in security, search & rescue missions

    Researchers have developed the first single actuator wave-like robot (SAW). SAW can climb over obstacles or crawl through unstable terrain like sand, grass, and gravel, reaching a top speed of 22.5 inches. The robot will be useful for traveling through the intestine for imaging and biopsies, and for infiltrating problematic, complex security areas, such as tunnels, destroyed buildings, and pipes.

  • Remotely disabling non-cooperative vehicles

    As they strive to keep the public safe, one of the key challenges facing European security services is the ability to control and stop, at distance, non-cooperative vehicles posing a threat. However, this ability presents more than a technical challenge. To comply with EU legislation, as well as adhere to ethical concerns, the technology would also have to be safe for the user, the driver (and passengers), as well as members of the public and the material infrastructure of the surrounding environment. In lab bench testing, researchers evaluated signal frequency, waveform, and duration — principally of electromagnetic pulses (EMP) and high power microwaves (HPM) — to determine which could best disrupt the functioning of a vehicle’s electronic components.

  • New tool keeps track of violent groups without having to geolocate the tweets

    Researchers have developed new sentiment analysis algorithms which can monitor the social network Twitter in search of violent groups. The system analyzes both the messages these individuals share and how their relationships develop. The police and other law enforcement agencies could use the tool to detect critical points, threats, and areas with concentrations of potentially dangerous people.

  • Separating the DNA of identical twins

    Since its first use in the 1980s — a breakthrough dramatized in recent ITV series “Code of a Killer” — DNA profiling has been a vital tool for forensic investigators. Now researchers at the University of Huddersfield have solved one of its few limitations by successfully testing a technique for distinguishing between the DNA — or genetic fingerprint — of identical twins.

  • U.K. reviews security measures for large outdoor events

    Amber Rudd, the new British home secretary, told the House of Commons that she has ordered a full review of the security measures taken to protect large outdoor events such as festivals and other public gatherings. The review comes in the wake of the attack in Nice on revelers celebrating Bastille Day. Rudd said that additional security measures will be put in place, including what is known as the “national barrier asset” when police assess that there is a risk of vehicle attacks.

  • DHS report highlights R&D priorities for technologies used in the field

    The Department of Homeland Security has released the Integrated Product Teams for Department of Homeland Security R&D Fiscal Year 2016 Report. The report identifies twenty-four focus areas for technological research and development (R&D), which fall under five mission areas: aviation security, biological threats, border security, cybersecurity, and counterterrorism.

  • DHS S&T demonstrates integration of first responder technologies

    More ruggedized protective equipment. Reliable and interoperable communications. The capability to filter vast amounts of data. These are all things DHS Science and Technology Directorate (S&T) Next Generation First Responder (NGFR) program envisions  to ensure future first responder are better protected, connected, and fully aware.

  • Roundup of spring, summer 2016 First Responders Group technology

    The DHS S&T regularly posts a roundup of key updates from projects currently in the development stages in S&T’s First Responders Group (FRG). S&T the other day offered an outline of FRG’s accomplishments in April, May, and June.

  • NIST releases 3D ballistics research database

    It is a staple of the TV-crime drama: a ballistics expert tries to match two bullets using a microscope with a split-screen display. One bullet was recovered from the victim’s body and the other was test-fired from a suspect’s gun. If the striations on the bullets line up — cue the sound of a cell door slamming shut—the bad guy is headed to jail. In the real world, identifying the firearm used in a crime is more complicated. However, the basic setup is correct. New forensic science database will provide a statistical foundation for more reliably linking bullets to the guns that fired them.

  • Eyewitnesses who collaborate make fewer mistakes in police interview

    Two recent studies show that witnesses make fewer errors when they are interviewed together than when they are interviewed separately. This stands in sharp contrast with current police guidelines to always interview witnesses separately.

  • Intelligence agencies spy on our data by manipulating computer chips

    Researchers work to develop mechanisms that will render the Internet of Things more secure. They focus on a specific security gap: the manipulation of computer chips, that is, hardware components. These components can be found not only in PCs and laptops, but also in all other devices with integrated electronics; those include credit cards, cars, and smartphones, as well as large industrial facilities and medical equipment.
