Laboratory Lanagement System about the Open Situation Based on the Homomorphic Encryption

User privacy data leakage which stored on the server has been all kinds of management system's safe hidden trouble. In order to solve this problem, this paper introduces the homomorphic encryption technology to the management system. Using the laboratory management system about the open situation based on the homomorphic encryption for example, by using a homomorphic encryption technology, let the user privacy data stored on the server in the form of ciphertext. Because of the homomorphic encryption technology to operation the ciphertext, so when the need for query, sorting, arithmetic operations about the primary data, it operates directly on the ciphertext. This ensures the privacy data confidentiality and security. Practice has proved, the laboratory management system about the open situation based on the homomorphic encryption has a very important role in the privacy and the security protection of private data on the server.
