Abstract:

Disclosed are a data access method, system and apparatus. When data is stored, firstly, a data storage instruction is determined; then, according to an identity identifier carried in the data storage instruction, a block chain corresponding to the identity identifier and a key pair are determined; and finally, data to be stored is stored in the block chain according to the key pair. When data is queried, firstly, a data query instruction is determined; then, according to an identity identifier corresponding to the data query instruction, a block chain corresponding to the identity identifier and a private key are determined; and finally, according to the private key, data in the block chain is decrypted and is then queried. Thus, by means of the method provided in the embodiments of the present application, when data corresponding to the identity identifier is accessed, there is no need to access a plurality of databases, and the block chain corresponding to the identity identifier only needs to be accessed, and data storage is performed via the key pair, so that the complexity of an operation can be simplified and the efficiency of data access can be improved while the security of data is ensured.
