Evidence Management Systems and the Use of Blockchain

The Use of Blockchain inside Evidence Management Systems was co-authored by Kris Lea. The analysis focuses on how blockchain technology can be used efficiently within the Law Enforcement chain of evidence, which is a supply chain for gathering evidence. By implementing a blockchain-based evidence management system, the issues associated with the traditional chain of custody—such as evidence loss, theft, tampering, and, worse, evidence manipulation—are reduced. The paper will outline the difficulties associated with keeping evidence on a blockchain and offer a practical fix. It will also utilize real-world examples from historical incidents to demonstrate how crucial this kind of system is to societies all around the world.

By the Numbers

A conservative estimate suggests that 20,000 people in the US are falsely accused, convicted, and incarcerated every year. Exonerations are few and far between, with 28% convicted due to mistaken identification, 12% gave false confessions, 23% due to forensic science problems, 54% attributed to official misconduct, and 58% due to perjury and false accusation. False convictions have led to a breakdown of trust between the members of the current US criminal justice system and the people of America, leading to the severe political turmoil seen today. Blockchain, a mathematically based and proven distributed ledger system, has shown promise in the supply chain arena, particularly in the tracking of goods.  (Source: The Innocence Project.

The writers, researchers, and co-authors of this publication have discovered methods for using blockchain to help track evidence, even when that evidence is digital.
