Abstract

The invention discloses a medical image file segmentation encryption and decryption system and method based on greenplum and relates to the technical field of computers. The medical image file segmentation encryption and decryption system comprises an encryption and decryption server used for encrypting or decrypting a received medical image file; a rule base used for storing a secret key generation rule and a segmentation ID generation rule; a key generation server used for generating a key and a segment ID according to metadata information given by the encryption and decryption server and the key generation rule and the segment ID generation rule obtained from the rule base and returning the key and the segment ID to the encryption and decryption server; a greenplum distributed databasecluster used for storing the generated secret key and the segment ID. According to the invention, sensitive information in the medical image file is encrypted in a segmented manner by utilizing a datasegmented encryption means based on the segmented ID, and only the sensitive information in the medical image file is encrypted instead of the whole file, so that the encryption and decryption efficiency can be improved, and meanwhile, the encryption security of the medical image file and the reliability of key storage are improved.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular to a system and method for segmented encryption and decryption of medical image files based on greenplum. Background technique [0002] With the continuous development and popularization of Internet technology and the development of network technology, the risk of leakage of sensitive data is also increasing. In particular, medical image files contain sensitive data of many patients, and file data is also easy to leak. How to It is becoming more and more important to protect the sensitive information in these medical image files from being leaked. [0003] There are currently many encryption algorithms for medical image files on the market, but on the one hand, the existing encryption algorithms use the same key to encrypt the entire file. This encryption method is relatively low in security. Once the key is cracked, all Sensitive information in medical image files is...
