Recently, the Criminal Procedure (Identification) Bill, 2022 was passed by the Lok Sabha. The bill seeks to replace the Identification of Prisoners Act, 1920, which authorised the taking of measurements for identification and investigation in criminal matters. A key feature of the bill is its widened definition of measurements, which includes iris and retina scans, behavioural attributes, including signatures, handwriting, finger impressions, footprint impressions, palm-print impressions, photographs, and also physical, biological samples “and their analysis.” The words “and their analysis” in the definition of measurements imply the possibility of using various sources of information to create profiles. As per the bill, the measurements would be retained in digital or electronic form for 75 years.
