I don’t need to explain the importance of fingerprints in criminal investigation proceedings. Fingerprints are crucial evidences that help investigators to get some vital clues about the criminals. However, with the rising cases of fingerprint tampering, it becomes very tough to obtain accurate data from fingerprint analysis.
The UK scientists are now coming up with a new system to identify individuals from partial, distorted, scratched, smudged, or warped fingerprints.
The researchers from the University of Warwick have developed a new technology to identify tampered fingerprints using a standard topological pattern co-ordinate system. The new technology converts the distorted fingerprints into a digital representation of the same. Then, they use an image space of all other finger prints stored in a database. The process takes few seconds to identify the damaged fingerprints.
The new technology has enabled the researchers to unwrap corrupt fingerprints using a standard topological pattern co-ordinate system. The unwarping of prints help people to compare the position of individual sweat pores on a fingerprint.
It was not possible till today because hundreds of pores on an individual finger are so thickly crammed that a least alteration of prints made it very difficult for people from using them to distinguish finger prints.
