A Design of Anti-image Tampering Model Based on Blockchain
An image security encryption algorithm based on blockchain technology is proposed to address the security and storage redundancy issues in current image encryption technologies.Firstly,the image is encrypted using an encryption algorithm based on singular value decomposition.Then,the encrypted key is uploaded to the IPFS interstellar file system for privacy protection.Finally,image tamper prevention is achieved by combining it with the Hyper ledger Fabric super ledger platform.Compared with traditional storage methods,the proposed encryption algorithm can effectively prevent image tampering,achieve image privacy protection,and reduce storage space load on chain.
