Problems solved by technology

[0008] In order to overcome the above disadvantages, the present invention aims to provide a private data encryption method for personal medical and health data. The length of private information encrypted by this method is not limited, and the longer the password, the higher the encryption strength, thereby solving the problem of mass data encryption. In this case, the consumption of server computing resources is a problem, and at the same time, it reduces the possibility of the encrypted ciphertext being cracked when using methods such as exhaustion and password attacks.

Abstract

The invention relates to a method for encrypting and decrypting private data for personal healthcare data, the length of the privacy information encrypted by this method is not limited and the longer the password, the higher the encryption strength is,thereby the problems of consumption of server computing resources in the case of large amount of encryped data, while reducing the possibility of being encrypted in the case of encrypted ciphertexts using methods of exhaustive and cryptographic attacks ect. In addition, the method for decrypting private data for personal healthcare data is used to support the encrypting method proposed by the invention, the method is easy to use with high reliability.

Description

technical field [0001] The invention relates to the field of privacy data protection, in particular to a private data encryption and decryption method for personal medical and health data. Background technique [0002] With the rapid development of computer application technology, especially large-scale new applications of cloud storage and cloud computing, which are oriented to regional health and medical and health service centers, the amount of medical and health data is increasing rapidly, and medical and health data has become a hot treasure. Protecting personal privacy involved in medical and health data without affecting mining and application has become a current research hotspot. [0003] In the process of realizing privacy data encryption technology, traditional encryption technology is generally used, such as symmetric encryption technology DES, AES, etc., asymmetric encryption technology RSA, Elgamal, etc., because most commonly used encryption algorithms are aff...
