Recent Advancements in Dermatoglyphics

Technology has substantially improved the reliability and accuracy of the field of Dermatoglyphics. It has made it possible to minutely scrutinize the fingerprint set. Today, we employ electronic digital technology with hardware and software customized for this application.

Digital Technology In The Field

Digital PrintThe procedure is inkless and it digitally captures the fingerprint on a system. The obtained data is then forwarded to our secure network server for in-depth analysis. This system eliminates the scope for human or mechanical error as inking is not involved. It also enhances the accuracy of the pattern matching and reduces the time to generate the report.

Digital FingerprintingToday, the automated systems are also incorporating the Surround Imaging Technology which enables even more accurate registration of the minutest details of the patterns and this three-dimensional imaging technique is an advancement in the capture and processing of patterns. The scanners are sophisticated and they extract features from a given fingerprint, including the ridge lines. The terminal point or divergence point of the ridge lines is also noted. The scanner/reader is also consistent in performance across a very large number of scans. Typically, very minimal user training may be required as there are LED indicators which prompt the user. Silicon sensing technology is gaining ground over the optical sensing, while they both produce certified image quality ( FIPS 201 standard).

The emerging application in rapid methods to record Fingerprints is that of a three-camera system. It scans under the fingers and obtains prints that are rich in details of finger ridge and valley. This system has incorporated highly sophisticated image-processing algorithms. Thus the frontier of technology in the field of Dermatoglyphics, both for recording and for analysis of Fingerprints, is being extended every year. At IMI Infinity, we are keenly noting the developments so that our systems and procedures can be duly upgraded to reflect the state-of-the-art.
