Abstract
In order to overcome the problem that the accuracy of privacy information mining in the existing privacy data encryption methods of student archives is lower than that of encryption security, this paper proposes a privacy information encryption method in student archives based on blockchain technology. In order to improve the effectiveness and security of encryption, singular value decomposition (SVD) method is used to mine the privacy information in students' archives. Based on the results of privacy information mining, combined with chaotic encryption technology in blockchain, the encryption function of privacy information in student archives is constructed to complete the encryption of privacy information in student archives. Experimental results show that, compared with the traditional encryption method, this method can effectively improve the accuracy of privacy information mining, and has high encryption security.
