The maritime sector is an industry that faces significant and various challenges related to cyber security and data management, such as fr aud and user authentication. Therefore, there is a need fo r a secure solution that can effectively manage data transactions while resolving digital identity. A biometric signature application in blockchain fo r fighting fr aud and fake identities may provide a solution in the maritime sector. This research proposes a biometric signature and an IPFS network-blockchain framework to address these challenges. This paper also discusses the proposed fr amework's cyber security challenges that threaten behavioral biometric security.
