AIIMS Bhopal Develops Tamper-Proof QR Code-Enabled Labeling System to Secure Forensic Evidence

Bhopal, Madhya Pradesh — In a pioneering move to enhance the security and integrity of forensic evidence, the All India Institute of Medical Sciences (AIIMS), Bhopal, has developed a tamper-proof, QR code-enabled labeling system designed specifically for forensic samples collected during medico-legal investigations. This innovative system promises to ensure secure storage, safe transportation, and judicial recognition of critical forensic evidence.

Funded through a two-year research project by the Indian Council of Medical Research (ICMR), this new labeling solution features a waterproof, single-use, tamper-proof label bearing an institutional seal and an encrypted QR code. The label can be directly affixed to evidence containers, providing multiple layers of security: it prevents tampering, allows digital traceability, and facilitates tamper detection.

Challenges such as label smudging or damage, sample mix-ups, exposure to moisture or contamination by rodents during long-term storage, and breaches in the chain of custody have often plagued the handling and transport of forensic samples. These issues can lead to the rejection of evidence in the judicial process, ultimately impacting legal outcomes. AIIMS Bhopal’s labeling system addresses these concerns effectively.

The label is resistant to common preservative substances used in forensic science, including water, salt solutions, alcohol, and formalin. It maintains durability and strong adhesion under adverse environmental conditions and even in cases of container leakage. The encrypted QR code provides case-specific identification and secure digital access to evidence data, making tracking and verification foolproof.

This development is expected to significantly enhance the confidence of law enforcement agencies, forensic laboratories, and judicial authorities in the handling and preservation of forensic evidence, thus strengthening the medico-legal investigation process in India.
