Encoding Content-Based Similarity in IPFS Pointer Names

The InterPlanetary File System (IPFS) is a distributed file system in a peer-to-peer network that manages various content. The exchange of content in IPFS employs a pointer that is calculated by SHA-256, which is a cryptographic hash function. This pointer is unique, but it is far from easy for a human to handle the content as in an existing file system. In this paper, we propose a method to create a hash that represents the similarity of content. Using this approach, a human should be able to recognize content in an IPFS as in an existing file system, which will improve usability.
