A Design of Anti-image Tampering Model Based on Blockchain

针对目前图像加密技术存在的安全性问题与存储冗余问题,提出一种基于区块链技术的图像安全加密算法。首先使用基于奇异值分解的加密算法对图像进行加密,然后将加密后的密钥上传到IPFS星际文件系统中进行隐私保护,最后通过与Hyper ledger Fabric超级账本平台结合实现图像防篡改。与传统的存储方式相比,所提出的加密算法能有效地防止图像篡改,实现图像隐私保护,减少链上存储空间负载。

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.
