New Fingerprint Technology Could Help Unsolved Crimes

A forensic team in the UK is using a new mass spectrometry technology that could help solve unsolved crimes, according to a news report.

The machine, developed by the University of Nottingham, fires ions at an object to create a "map" of the substance it finds, such as sweat. It produces constant and reliable results and does not damage existing evidence, as current methods of making a copy of fingerprints are not good enough and DNA swabbing can damage evidence.

The machine detects fragments of the substances from fingerprints and it is able to form a pattern on a computer that interprets the findings as a recognizable print, which can help cases where fingerprints are difficult to retrieve. Scientists say that it can make copies without damage occurring.

In today's rapidly evolving security landscape, organizations face an ever-growing array of disruptive events, security threats and risks. Traditional reactive approaches to security intelligence often leave businesses vulnerable and ill-prepared to anticipate and mitigate emerging threats that could impact the safety of their people, facilities or operations.
