Dematerialization of physical evidence is an asset of digitizing information, where information from physical evidence becomes more important than physical evidence itself.In principle, to preserve digital evidence, an accurate and reliable distributed storage system is needed that is packaged in terms of asset digitization which are summarized in chain of custody (CoC) documents.In addition to addressing all the needs related to the storage system, one thing that is no less important is to focus on the ease of distributing evidence on the network safely and reliably.This is one of the most important parts of interpreting the effectiveness of digital forensic investigations.However, several problems arose regarding the concept of managing digital evidence asset storage which still cannot be distributed, and is difficult to track.The purpose of this research is to complement the concept of Digital Evidence Cabinet (DEC) by combining InterPlanetary File System (IPFS) and Hyperledger Fabric (HF) as a distributable storage system.By proposing an alternative approach to the IPFSChain model, it is possible to achieve ease of data transfer, better data trust and protection of its ownership.The contribution of this research is to provide the concept of IPFSChain as a distributed storage model and all activities on assets can be audited properly by considering the rules of chain of custody.
