Identifying Gender from Fingerprints

Nov-28-15 A new technology that allows a person’s gender to be identified from their fingerprints could help speed crime investigations.

The technique, developed by a team from the University of Alberta led by Jan Halámek, is based on the knowledge that females’ sweat contains about twice the level of amino acids as males’. To carry out the identification process, the team first transfers the fingerprint onto a piece of thin plastic, where the fingerprint is bathed in a hydrochloric acid solution and heated. This causes the amino acids to move into the acidic solution, where the levels can be measured and used to determine the gender of the person.

In tests, the procedure was 99 percent accurate, and worked on fingerprints collected from virtually any type of surface.
