Context: The Supreme Court has considered the submission of the Centre that it would move a Bill in the upcoming Parliament session for DNA profiling to enable authorities to maintain records of unidentified and unclaimed dead bodies or missing persons.


The government was responding to a PIL petition on the use of DNA profiling for identifying unclaimed bodies, especially to match them with old cases of missing persons.

Human DNA Profiling Bill:

The Centre’s Human DNA Profiling Bill, 2015, was prepared by the Department of Biotechnology and the Hyderabad-based Centre for DNA-Fingerprinting and Diagnostics. Several organisations and individuals, however, raised concerns that the bill gave sweeping powers to the government to mine the database and use it for purposes beyond just solving the crime.

Since there are concerns about the integrity, authenticity and distribution of the database, Blockchain can solve all of these.

Using Blockchain, the database would also be decentralised


  • The concerned authority can even use its own private blockchain.
  • The database would also be decentralised – hence, no single point of failure (e.g. a single database server).
  • Authorities or stakeholders can verify transactions and invalidate corrupted blocks (or data).
  • Immutable previously encrypted blocks hence would protect integrity.
  • Using public blockchain would help stakeholders or public to see transactions about the database usage – e.g. validating who demanded the database and why was it demanded. This doesn’t necessarily mean that they would be able to see ‘how’ or ‘what’ database is exactly used.

There are many pros to using Blockchain technology in a scenario like this. Use cases like these are implementing Blockchains and are very popular in news – Rent agreements, Andhra Pradesh government, KYC for State Bank of India. You may consider giving this a try. 🙂
