基于区块链技术的用户行为数据防篡改仿真

Tamper Proof Simulation of User Behavior Data Based on Blockchain Technology

传统的用户行为数据加密方法,缺少系统的二次密文,导致了用户行为数据的保密性不足,于是提出一种基于区块链技术的数据防篡改方法,通过区块链技术确定用户行为数据储存的最大化效果,利用转换函数转移并加密储存原数据,依靠多个小区块组建区块链的数学模型,并输出二次密文,验证用户行为数据并对其进行加密和解密,以此来完成用户行为数据防篡改方法的设计。实验证明,所提方法有效提高了用户行为数据的保密性,同时不会影响到数据管理系统的运行性能。

The lack of secondary ciphertext leads to poor user behavior and the confidentiality of data encryption methods. Therefore, this paper proposes a data tamper proof method based on blockchain technology. According to blockchain technology, the maximization effect of user behavior data storage was obtained. The conversion function was introduced to transfer and encrypt the original data. The mathematical model of the blockchain was composed of multiple small blocks, and the secondary ciphertext was input. The user behavior data were verified, encrypted and decrypted, completing the design of anti-tampering method of user behavior data. The experiments show that this method has excellent user behavior data confidentiality, and the operation performance of the data management system is not affected.
