Forget fingerprints and iris scans--a new form of biometric identification will use body odor to identify the individual. Every person's individual body odor is unique, and can be used to identify an individual with an accuracy rate of more than 85 percent. The odor-identification method may provide a more subtle alternative to the current biometric techniques like fingerprints and iris scans--techniques that are often associated with criminal records and could cause people to be...

The DNA fog tagging system can mark an intruder without their knowledge, making it easier for police to identify them later. DNA marking has already been in use by law enforcement agencies, with the most common use being to mark persons of interest at riots. The new system will be a bit more general, and will be meant to help stop and identify an intruder. Called DNA Fog, the device will fill a room with smoke and DNA-loaded droplets when triggered by a break-in. More than just...

"So, Where Are You From?" I've struggled with this question and resulting self-identity issues for the larger portion of my life. Am I from Russia, Canada, USA, or China? Who am I and where is home? I've been through hell to find an answer that satisfied me. Then suddenly, something started clicking. The puzzle was finally solved and everything in the past made sense. Through sheer luck, coincidence, intuition, and events beyond my control, I have stumbled upon an idea that resolved it all....

A new portable scanner for police departments will make it easier for officers to detect weapons, such as knives or guns, on a person's body. The device will use infrared light image the natural radiation gives off by a person's body. When a solid metal object blocks the rays, the image shape will show up on the scanner screen.

Police may soon be able to use a new automated graffiti identification software to help them keep tabs on gang territory and drug deals. The system will be able to compare photos of graffiti to identify which gang, and sometimes even which individual, created it. Identification will be based up on constant key points in the design and will use crowdsourcing to help decipher unintelligible text. An accuracy rate is supposed to be about 65 percent and higher.

A new technique using gold nanoparticles will make it easier to analyze old, dry fingerprints, possibly adding new evidence to cold cases. Why not develop a new method of targeting amino acids in sweat by combining antibodies that will bind to amino acids with gold nanoparticles. The antibodies will bind to the amino acids, and the gold nanoparticles will help to bring the details of the fingerprint into sharper focus.

Why not provide police officers with facial recognition glasses to help them scan crowds and check the faces against a criminal database. The glasses will scan 400 faces per second at up to 50 yards away by comparing 46,000 biometric facial points. A red light will come on in the frame of the glasses if a match is detected, allowing the police to quickly identify potentially problematic people.

The way described below seems to be an effective one while recovering fingerprints from clothing. This method works by placing the fabric in a vacuum chamber. Then a fine layer of evaporated gold is spread over the fabric, followed by an application of heated zinc. The zinc attaches to the gold layer where there are no fingerprints, allowing the fabric where contact was made to show through. The technique could be useful in targeting areas of clothing where a victim was grabbed or...

Why not create software to scan videos of crime scenes and identify frequently reoccurring faces? This will help with the identification of individuals who may know something about the crime. The software will work from any video stream, including cell phone video. It could also be used to count the number of times an individual shows in a particular location, and mark that person as a possible person of interest if they appear more than a certain number of times.

A designer from India invented a unique jeans design, which helps to protect wallets from pickpockets. The main feature of these jeans is that there is a copper wire in their seams. The wire is connected to a special device consisting of capacitors, a 3-volt battery and a magnetic switch. This electric device is placed in a case and can be activated by the user at any time. Its mechanism of action is simple - once a thief feels about for the wallet in your pocket, he is...
