Ensuring the Integrity of the Police Complaint Files Using Blockchain Technology

Information about every criminal case is kept in a very secret police case database system. During the course of an investigation and case resolution, criminal information is handled differently in each case. However, the traditional police case information management system is not extremely secure. Although every police station has a system for recording criminal history, the data transfer is still not transparent. Many police stations still run their operations with manual systems. Any unethical action might cause unfairness for the victims. As a result, we are offering a secure platform that combines the openness as well as adaptability of smart contract-based systems with the accuracy and secrecy of current police case schemes. We have created a smart contract on the blockchain's Go Ethereum platform using the Proof-of-Authority (PoA) consensus mechanism to verify the user and offer transparency for the security of criminal records and evidence. Our proposed solution runs on a distributed network for the best possible data security that adheres to the Web 3.0 model.
