Delhi becomes the first ever city to introduce blockchain for tamper-proof FSL report

By Nidhi Bhardwaj: While the concept of blockchain technology has been around for a while, Delhi has recently announced the use of blockchain technology in crime investigation and has become the first city in the country to have done this.

According to the sources, this move is expected to protect investigations against tampering and facilitate the swift transfer of reports to the court. The Delhi government has introduced blockchain technology in the Forensic Science Laboratory (FSL).

How beneficial this move would be?

Blockchain is being touted as the next big thing in digital security. Moreover, the latest report on its usage suggested that banks, financial firms & governments prefer this technology to store their sensitive data in a safe and secure way.

In this case, blockchain would ensure the immutability of records, lend reliability to digital evidence and provide effective audit trail capabilities, said officials. Blockchain, uses cryptographic hashing to make the history of digital assets unalterable and transparent. According to recent information, the new system will also include such security measures to protect FSL data from hacking.

As cited by IT department officials, this technology would be soon introduced in securing data of various certificates such as caste, domicile, character certificate as issued by the revenue department, and afforestation records.

Security is introduced in stages

In order to ensure that the chain of custody (the process by which evidence is handled through its various stages) is not tampered with, blockchain-based interventions have been implemented in four stages. “When the samples, along with the copy of the FIR and the queries, are received, when the case is assigned to an investigator at FSL, during finalising the report, and when it is dispatched,” said an official.

Moreover, to make a change at any stage, the existing record cannot be altered, and a new block must be created. If there is any attempt to tamper with the record, all authorised persons will be notified immediately.

Previous blockchain use case in FIR

After introducing a new police complaint system that utilises blockchain technology to avoid corruption, the Indian Police has built the country’s first complaints web portal on the Polygon blockchain previous year. The portal allows the general public to file the ‘first information report’ (FIR) and track it in real time. The initiative was taken by famed IPS officer Ashish Tiwari, in the Indian Police Service. Furthermore, with the aid of blockchain, the complaints will remain public and transparent, which does not allow admins or police officers to alter complaints on it.
