CRAB: Blockchain based criminal record management system

Abstract

Criminal records are highly sensitive public records. By incorporating criminal records in a blockchain, authenticity and rigidity of records can be maintained; which also helps to keep the data safe from adversaries. A peer to peer cloud network enables the decentralization of data. It helps prevent unlawful changes in the data. This paper introduces a criminal record storage system by implementing blockchain technology to store the data, which helps to attain integrity and security. Our system presents ways in which the authority can maintain the records of criminals efficiently. Authorities (e.g., Law enforcement agencies and courts) will be able to add and access criminal data. General users (e.g., selected organizations and/or individuals, airports, visa application centers etc.) will have access to the data so that they can look up criminal records. Proper and timely access to authentic criminal records is essential to enforce the law. The effect of corruption on the law enforcement forces will also decrease, as this will cut off an entire scope of corruption by removing any possibility of tampering with criminal records data by thorough accountability.
