DNA Records Latest News
- Police across several Indian states have begun collecting DNA records of suspects under the Criminal Procedure (Identification) Act, 2022, with over one lakh DNA profiles generated and stored in a central database operated by the National Crime Records Bureau.
About the Criminal Procedure (Identification) Act, 2022
- The Criminal Procedure (Identification) Act, 2022 (CrPI Act) is a significant piece of legislation passed by Parliament in 2022 to modernise India’s criminal investigation framework.
- It replaced the colonial-era Identification of Prisoners Act, 1920, which had limited provisions for collecting only fingerprints and footprints.
- Background
- The 1920 Act was considered outdated in the era of advanced forensic technology. The new law was enacted to:
- Modernise identification techniques in line with global standards
- Strengthen the criminal justice system through scientific evidence
- Improve conviction rates by enabling accurate identification
- Solve interstate crimes through a unified national database
- Key Provisions
- The CrPI Act empowers police and prison officers to collect a wide range of identification data from:
- Convicted persons
- Arrested persons for offences punishable with imprisonment of seven years or more
- Persons detained under preventive detention laws
Types of Measurements Collected
- The Act allows the collection of:
- Fingerprints and palm prints
- Footprints and photographs
- Iris and retina scans
- Physical and biological samples, including blood and saliva for DNA profiling
- Behavioural attributes, including signatures and handwriting
Data Retention
- Records can be retained for up to 75 years from the date of collection.
- Data is stored in a central database maintained by the National Crime Records Bureau (NCRB).
- Records are deleted when a person is acquitted or discharged in all proceedings.
Authorised Agencies
- The CrPI system is accessible to:
- State police forces across the country
- Central agencies, including the Central Bureau of Investigation (CBI), National Investigation Agency (NIA), and Narcotics Control Bureau (NCB)
- Prison authorities for record collection
Concerns and Criticisms
- The Act has faced criticism on several grounds:
- Privacy concerns regarding mass collection of biometric and biological data
- Potential misuse by authorities
- Vague definitions of who can be subjected to collection
- Lack of judicial oversight for collection from arrested persons
- Long retention period of 75 years raises proportionality questions
- The Supreme Court’s Puttaswamy judgment (2017) recognised privacy as a fundamental right, making it essential to balance security needs with individual rights.
News Summary: Implementation of the CrPI Act
- Over the past five months, the DNA records of more than one lakh suspects have been stored in a central database operated by the National Crime Records Bureau (NCRB) under the Union Home Ministry.
- The contours of the CrPI system were showcased on June 19 at an NCRB event presided over by Home Minister Amit Shah.
Infrastructure for Implementation
- The implementation has involved significant infrastructure development:
- More than 2,600 measurement collection units have been established across the country
- The CrPI system is now available in police districts and prisons
- It is accessible to Central agencies, including CBI, NIA, and NCB
- Integration with forensic laboratories for processing biological samples
Sample Collection Process
- Samples are currently being collected by police in cases punishable by seven years or more.
- DNA samples are primarily drawn from blood, with saliva used in some cases.
- Samples are sent to a forensic laboratory, which generates a unique number.
- The NCRB preserves the code in its records.
- The sanctity of the samples depends on the police maintaining proper protocols.
National Automated Fingerprint Identification System (NAFIS)
- To support the CrPI system, the NCRB had launched the National Automated Fingerprint Identification System (NAFIS) in 2022:
- Fully automates the fingerprint matching process
- Currently holds more than 1.27 crore fingerprint records
- Has played a significant role in solving old inter-state criminal cases
- Provides instant matching capabilities across the country
Advanced Features of the CrPI System
- Unified national database integrating face, iris, and biological samples.
- Searchable database enabling accurate scientific identification within moments.
- Photo matching, a photo from a crime scene can be instantly matched with records across the country.
- Video analytics allowing investigating officers to upload CCTV footage to identify suspicious persons.
- Standardised storage of measurements for 75 years.
- Disguise-resistant identification, photos are taken ensuring clarity of eyes to prevent identification being hindered by disguises.
Crime-Solving Capabilities
- The system enables several important crime-solving functions:
- Direct matching of biological samples recovered from crime scenes with existing records.
- Identification of habitual offenders through scientific methods.
- Inter-state criminal tracking with instant cross-state record matching.
- Quick identification from CCTV footage that earlier took hours of manual investigation.
- The NCRB stated: “What earlier took hours of manual investigation is now possible in just a few minutes.”
Concerns and Way Forward
- Privacy and Civil Liberties
- Proportionality of data collection and retention
- Safeguards against misuse of sensitive biological data
- Independent oversight of database access
- Data security to prevent breaches
- Compliance with the Digital Personal Data Protection Act, 2023
- Implementation Challenges
- Standardising procedures across states
- Training law enforcement on proper collection techniques
- Maintaining the sanctity of samples and the chain of custody
- Integration with state databases
- Need for Safeguards
- Judicial oversight for sensitive data collection
- Clear protocols for data deletion upon acquittal
- Regular audits of database access and use
- Transparency in operational procedures
- Periodic legislative review of the framework
