Problems solved by technology

In order to protect the security of private data, in the prior art, the private data is usually desensitized and stored in the database, but when the private data is retrieved or checked, the data used for comparison is usually desensitized. For the sensitized private data, if fuzzy comparison is performed based on the desensitized data, the data matching accuracy will be low. If the desensitized data is restored and then compared, it will take more data recovery time and reduce the data loss. Matching efficiency, and data security cannot be guaranteed

Abstract

The embodiment of the invention discloses a data query method and device, electronic equipment, a storage medium and a program product, and the method comprises the steps: responding to a received data query request, and obtaining a query request and query object information carried by the data query request; sending an encrypted to-be-queried object acquisition command to a database according to the query object information, and acquiring an encrypted to-be-queried object which corresponds to the encrypted to-be-queried object acquisition command and is obtained by encryption based on a first preset encryption algorithm, decrypting the encrypted to-be-queried object into an original to-be-queried object in a security area of a trusted execution environment based on a first preset decryption algorithm; and executing a query operation based on the original to-be-queried object according to the query requirement to obtain a data query result.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of data processing, and in particular to a data query method, device, electronic equipment, storage medium, and program product. Background technique [0002] With the development of Internet technology and big data technology, more and more information and data need to be saved, including private data such as ID card and mobile phone number. In order to protect the security of private data, in the prior art, the private data is usually desensitized and stored in the database, but when the private data is retrieved or checked, the data used for comparison is usually desensitized. For the sensitized private data, if fuzzy comparison is performed based on the desensitized data, the data matching accuracy will be low. If the desensitized data is restored and then compared, it will take more data recovery time and reduce the data loss. Matching efficiency, and data security cannot be guar...
