Criminal Evidences Management System Using Blockchain

The Criminal Evidence Management System with Blockchain is a safe and reliable mechanism to store and manipulate criminal evidence. In conventional systems, the evidence may be altered, lost or misused due to the fact that the evidence is stored in central databases. The problem is addressed in this project through the adoption of blockchain technology that secures evidence, which is considered permanent, safe, and unaffected.   Under this system, all evidence records are recorded with a hash value and a time. Smart contracts regulate access to evidence addition or access and all operations are automated. This will aid in preservation of the chain of custody and enhance confidence in the police investigations and court cases.   The findings indicate that the system is successful and enhances security, transparency, and accountability. Evidence is safe and any effort to alter evidence can be realized at once by the admin as well as officers. This ensures that the justice process is less biased.
