Abstract - Handling forensic evidence with precision, storing it safely, and maintaining correct chain of custody records are
all essential components of contemporary criminal investigations. Data manipulation, unauthorised access, and a lack of transparency are problems that traditional evidence management systems have. This study discusses a novel use of blockchain technology in the forensic evidence management system to overcome these problems. To guarantee the integrity, security, and transparency of forensic evidence throughout its existence, the suggested method makes use of blockchain's decentralised and immutable properties. To increase productivity and lower the possibility of human mistake, smart contracts are used to automate the chain of custody procedure. The proposed system leverages the suggested method makes use of blockchain's decentralised and unchangeable structure to guarantee the authenticity, safety, and transparency of forensic evidence for the course of its existence. By automating the chain of custody procedure, smart contracts increase productivity and lower the possibility of human mistake. Furthermore, the legitimacy of the evidence may be confirmed with the use of cryptographic hashing techniques without disclosing private information. A blockchain-based forensic evidence management system prototype was created and put through testing in a controlled setting. The evaluation's findings show that the system safeguards private data from unauthorised parties and offers better accessibility, accountability, and data integrity.

1. INTRODUCTION An imprecise approximation compiled from several academic and journalistic sources indicates that over 20,000 Americans are wrongfully charged, found guilty, and imprisoned year. Since no single organisation gathers verified information about exonerations resulting from mistaken convictions—and even if it did, it would not be able to know about the situations in which someone was never exonerated—it is necessary to use a variety of sources to approximate the number. Exconerations are rare among the estimated 20,000 people wrongfully charged, convicted, and imprisoned in the US alone. Contributing factors have resulted in 28% of convictions due to erroneous identification, 12% of false confessions, 23% of forensic science-related exonerations, 54% of official wrongdoing, and 58% of false accusations and perjury-related exonerations. (Source: The Innocence Project. More than 100% due to some cases having multiple contributing factors.) In fact, according to the National Institutes of Justice, “The most significant number of wrongful convictions in which forensic science is considered a contributing factor is attributable to eyewitness misidentification and official misconduct.” Many people effectively lose their entire lives to false imprisonment as the average term served by those falsely convicted was 10 years. That’s a decade in the life of a broth er, sister, father, mother, colleague, or student who will not be allowed to contribute fully to society once falsely convicted of a crime. Even after release, convicts struggle throughout their lives to gain and keep opportunities those without a criminal history are provided. Blockchain technology, which offers a decentralised and unchangeable ledger system, has completely transformed. a Evidence management is one area where blockchain technology shows great promise. Conventional evidence management systems frequently encounter issues with transparency, security, and data integrity. The purpose of blockchain-based evidence management systems is to leverage the inherent characteristics of blockchain technology, like immutability, transparency, and decentralised consensus, to overcome these difficulties. Electronic proof can be managed and stored in a safe, unchangeable
