Increasingly blockchain could help verifying criminal evidence

Nowadays, there was huge amount of interest in blockchains with technology sustaining currencies Bitcoin. Meanwhile, we are intense to explore their potential uses within government.

Blockchains are an illustrations of Distributed Ledger Technology (DLT). Since, it is an authoritative system of record where everyone who contributes to the blockchain gets a permanent record of every transaction.

Significantly, one intention doesn’t mean everyone to ‘just trust’ a single authority. Therefore, the trust is distributed and decentralized amongst the users.

Recently, UK Ministry of Justice believes blockchain could help the government secure and verify digital evidence.

The technical architecture lead at the Ministry, Alistair Davidson, notably mentions blockchain uses case related to law enforcement.

Davidson mentions a noteworthy exploration of how blockchain use by Justice Ministry, a public-sector entity. He added that such utilization is useful in court.

Davidson writes:

“This property of distributing trust could be genuinely transformational in situations where public trust of government might not misuse”.

For instance, a state in a criminal prosecution in which emails, documents, and video footage evidences becomes much more important.  It ensures that mechanisms and procedures for verifying the integrity of evidence are up-to-date.

Moreover, all data must be stored, well-manage, assembled and made accessible. Since, number of people use high quality video editing software as sustaining trust in the integrity of the data is being complicate.

In such situation, DLT could help. The following are several functions that it performs:

  • Provides safe cloud storage and precise access.
  • Keeps metadata record about each clip.
  • Calculates a hash (fingerprint data) of the clip and of the metadata.
  • Records the hashes of the clip and its metadata onto a blockchain.

Since, the blockchain would be readable by anyone, anywhere but writable by the police. Thus, it provides a verifiable record that the video data being upload from the device.

If at all, videos are uploaded to a publicly available cloud storage, “the blockchain would be readable by anyone, anywhere – but only writable by the police”.

Although, if the portion of video is requires in court, it is explicitly, cryptographically verified that video is exactly identical.

Simultaneously, the blockchain is distributed, append-only and near real-time. Since it could verify for themselves that the evidence has been not been tamper with more plans. Furthermore, there could no possibility of records being falsified after the fact without detection.

According to Ministry of Justice, the government explains that though blockchain is unassailable, it can only authenticate the resources stored after they are in list. But, still files can modify prior to being list on the blockchain.

Moreover, the possibilities of revolutionary technology of transformation government as well as entire society.
