New Delhi Police Start Using Blockchain to Store Evidence Data

Police in the Indian capital of New Delhi have begun using blockchain and distributed ledger technology (DLT) to store information and improve the criminal investigation process.

A representative of the Forensic Science Laboratory (FSL) said that the blockchain will allow transparent storage of information about physical evidence obtained from a crime scene.. Blockchain will be applied at several stages, from collecting samples to sending them.. Each stage of the process is fragmented and protected from unauthorized access to data, the representative of FSL explained.

Existing records can no longer be changed, so to make amendments or additions, you will have to create a new block and generate a new QR code. When attempting to falsify a record, all authorized persons will immediately receive alerts. Given the transparency and immutability of stored data, blockchain will increase citizens' trust in New Delhi law enforcement, FSL employees believe. In addition, thanks to this technology, the number of solved criminal cases will increase.

FSL investigators receive about 1,500 crime scene samples every month, and law enforcement officers have to study them using traditional methods, which slows down the investigation process. In the future, DLT can be used by law enforcement officers from other Indian states, but in this case, the Crime and Criminal Tracking System (CCCTNS) will have to be upgraded.

India is not the only country interested in using blockchain to fight crime. Last March, the Dubai police announced that they would use artificial intelligence (AI) and blockchain to predict and prevent emergencies in public places.
