In the proceedings of the court of law, it is of vital importance that the digital evidences are produced untampered during the entire Chain of Custody (Coc) process. Recent advancements in computer technology have enabled hackers to compromise with the integrity of the evidences. In order to secure these evidences from such external agents we have proposed a Blockchain model. Unlike the traditional security systems, Blockchain Technology uses cryptographic hashing in which each block has a cryptographic hash of its previous block i.e., A growing list of records that are called Blocks. These blocks are secure and tamperproof. The idea of this work is to handle the digital evidence from the time it is retrieved to the point it is presented as an evidence in the court of law. It ensures safeguarding of the evidence during the entire Chain of Custody process, which is fundamental to the idea of digital forensics. The aim of Digital Forensics is to maintain evidences in their most original form while performing a structured investigation by the collection, identification and validation of the digital information for the purpose of reconstructing events from the past. The proposed system ensures integrity, traceability, authenticity and security of the evidences. |
