Abstract

The embodiment of the invention provides a data encryption method, device, equipment and system and a data decryption method, device, equipment and system, and relates to the field of data security. The data encryption method comprises the following steps: receiving an encryption request for encrypting specified data; acquiring an encryption rule corresponding to field information in pre-stored currently-effective privacy version configuration information; and encrypting the specified data according to the searched encryption rule. The specified data is encrypted through the preconfigured currently-effective privacy version configuration information. The problem of low security of encryption and decryption methods provided in the prior art is solved. The effective privacy version configuration information is updated automatically along with time, so that the probability of forced cracking of encrypted data can be lowered to a great extent, and the security during data encryption or decryption can be enhanced greatly.

Description

technical field [0001] The present invention relates to the field of data security, in particular to a data encryption method, a data decryption method, a device, a device and a system. Background technique [0002] With the continuous development of network technology, data privacy protection has become a security function that network operators and Internet companies focus on. Especially in the field of business intelligence (BI, Business Intelligence), data warehouses (DW, Data Warehouse) often store a large amount of data, some of which involve user privacy (such as mobile phone numbers, user names, user home addresses, bank accounts, certificates, etc.) Numbers, etc.) usually need to be encrypted before entering the data warehouse, and the data can be decrypted when the data needs to be displayed. [0003] At present, there is a data encryption method, which may include: the management terminal obtains the data in the external data source and the field information of t...
