The fundamental aim of digital forensics is to discover, investigate, and protect an evidence, increasing cybercrime enforces, digital forensics team have to more accurate evidence handling. It makes digital evidence as an important factor to link persons with criminal activities. A chain of custody refers to a process of recording and preserving in court of law. It forms the forensic link of evidence sequence of control, transfer, analysis to preserve integrity, and to prevent its contamination. Thus it is of utmost importance to guarantee integrity, authenticity, of digital evidences in cyber-crime investigation. So guaranteeing the authenticity and legality of processes and procedures used to gather and transfer the evidence in a digital society is a real challenge. Block-chain technologies of enabling view of transaction back to origination provide enormous promise for the coming era.it is also used for securing IoT devices through efficient authentication and data transfer mechanisms. Block-chain based digital forensics chain of custody, influence forensic applications in bringing integrity to digital forensics.
