The blockchain technology could help government to verify digital crime evidence, said a UK Ministry of Justice’s official, Alistair Davidson. A blog post was published by Davidson, a technical architecture lead at the Ministry on Thursday that contained a blockchain use case for creating records for officer-worn camera footage using the technology. Even though the blog post looks largely hypothetical, it’s a new innovation of how blockchain could be used by public-sector entities. According to Davidson, such exploration can be useful in court were the ledger record could prove the video’s authenticity.
Alistair Davidson, a technical architecture lead at the UK Ministry, published a blog post Thursday which outlined a notable blockchain use case related to law enforcement: using the tech to create records for officer-worn camera footage.
“This property of distributing trust could be genuinely transformational in situations where public trust of government might not be taken for granted.”
He stated that the ledger would not actually store the video but would contain a hash of the video’s data and metadata and its list of location within the government’s storage area. Davidson wrote if the videos were stored as such then “the blockchain would be readable by anyone, anywhere – but only writable by the police”.
The government indicated that blockchain can only verify the assets stored after they are listed as it is immutable. Even by listing on the blockchain, files are susceptible to modification.
