基于区块链的隐私信息安全共享技术

为提升隐私信息安全共享效率,提升网络用户的隐私信息安全共享体验,本文提出一种基于区块链的隐私信息安全共享技术。利用MapReduce技术对隐私信息同态加密,设立隐私信息第一道安全防护,利用区块链技术对隐私信息重加密处理,使用哈希函数根据隐私信息属性集合生成密钥,并建立安全构造,设立隐私信息第二道安全防护,利用解密算法对隐私信息解密,获取到隐私信息文件,从而实现基于区块链的隐私信息安全共享。实验结果表明,设计技术的隐私信息安全共享耗时较短,在隐私信息安全共享方面具有一定应用价值。

In order to improve the efficiency of privacy information security sharing and enhance the privacy information security sharing experience of network users,this paper proposes a privacy information security sharing technology based on blockchain.Use MapReduce technology to encrypt privacy information homomorphically,set up the first security protection of privacy information,use blockchain technology to re encrypt privacy information,use hash function to generate key according to privacy information attribute set,establish security structure,set up the second security protection of privacy information,use decryption algorithm to decrypt privacy information,and obtain privacy information files,So as to realize the secure sharing of private information based on blockchain.The experimental results show that the design technology of privacy information security sharing takes less time,and has certain application value in privacy information security sharing.
