NEW DELHI: Four applications launched by home minister Amit Shah Friday — Abhigyan, Criminal Procedure Identification (CrPI), e-prosecution 2.0 and e-forensics 2.0 — promise to integrate policing, criminal identification, forensic probe and prosecution management into a seamless digital chain of the Integrated Criminal Justice System, expediting investigation and prosecution through use of technology.While National Automated Fingerprint Identification System (NAFIS) and CrPI will identify the offender, the Crime and Criminal Tracking and Network System (CCTNS) and Crime Multi Agency Centre (Cri-MAC) will connect and support investigations. E-forensics will strengthen evidence and e-prosecution will drive the case towards conviction.Over the past four days, Shah has posted on X explaining the functions of the four apps. The first set of posts, uploaded Friday, said the four apps “will equip our agencies with the key to speed and accuracy in justice delivery by enabling instant matching of fingerprints; integrated DNA, iris and face matching; and seamless digital coordination among the agencies”.In a post on ‘Abhigyan’, Shah said it “enables field police personnel to search the NAFIS comprising 1.3 crore fingerprints, using their smartphone to identify a suspect”. He added: “This app, secured through two-step authentication, is strengthening ground policing through real-time fingerprint-based identification. Powered by fast identification, portable setup and crores of records, the Abhigyan app is a very robust tool”.
