The invention provides a data storage and transmission method and device based on an identification technology, and the method comprises the steps: carrying out the asymmetric encryption of original data after the to-be-stored original data is obtained, obtaining encrypted data, and carrying out the hash calculation of the identification of the original data, so as to obtain mark information; storing the encrypted data and the mark information; under the condition that query information of to-be-queried original data is received, retrieving encrypted data indicated by the query information from stored data to obtain query encrypted data, wherein the query information of the to-be-queried original data is obtained by performing hash calculation on an identifier of the to-be-queried originaldata; and sending the query encrypted data to the opposite terminal. Because the original data is stored and saved by the encrypted data encrypted by the asymmetric encryption algorithm, and the identification of the original data is stored and transmitted by the mark information calculated by the hash algorithm, the safety of the stored data and the transmitted data is provided.
Description
technical field [0001] The present application relates to the field of electronic information, in particular to a method and device for data storage and transmission based on identification technology. Background technique [0002] With the rapid development of informatization in the Internet era, a large amount of data is generated in the production and operation of various industries. With the generation of big data, a steady stream of data leakage has also been brought, resulting in incidents such as network fraud. Therefore, in the era of big data , the generated data should be encrypted for privacy. There are two main aspects of data leakage: (1) data storage; (2) data transmission, as follows figure 1 shown. [0003] The data is stored in the database in the data center in plain text, and the data between different databases is transmitted through the network. On the one hand, the data transmitted in the network is easily intercepted by criminals; on the other hand, ...
