Abstract

Forensic science plays a crucial role in investigating crime events through scientific methods. It collects evidence based on fingerprints and DNA analysis that must be presented in court for judgment. It faces difficulties in investigating the data between interconnected devices and also faces data privacy and security issues. Blockchain technology provides solutions by creating immutable and transparent records through a chain of interconnected blocks. Since it creates a copy of transactions and makes it available for all the nodes in the chain, modifying or deleting a transaction becomes difficult. This chapter discusses the role of blockchain in enhancing data privacy and security in evidence integrity and also discusses the various techniques, advantages, and challenges faced by blockchain in cyber forensics.
