In the current scenario, the demand for Computerizatio and data security has Been increasing to combat with the increasing rate of crimes in the society. In the existing solution for prison management system there exist substantive data symmetry among prisons. Thus, during access of any prisoner detail, system may provide inappropriate details. Our objective is to implement a novel approach that stores the prisoners credentials and efficiently verifies the prisoners credentials via the block chain technology. Our proposed solution is implements in the Hyperledger framework and the experimental result shows that our proposed solution is beneficial for the existing and upcoming investigation department. Keywords: Prisoners Credentials, data security, block chain. criminal records.
