Abstract

The invention discloses a hidden trace query method, which relates to the field of data interaction, and is characterized in that under the condition that attribute data does not go out of a database of a data owning party, a target query feature signature received by a query party encrypts a query feature through a private key generated by the data owning party; and the data query party signs the target blind query feature sent by the query party, and the query party can decrypt the target attribute data through the signature of the target query feature to obtain the target attribute data. Therefore, the hidden trace query method provided by the invention does not depend on a third party to generate a secret key or carry out interaction, and the risk of data leakage is reduced. The invention further provides a hidden trace query device and a computer readable storage medium, which correspond to the method and have the same effects.

Description

technical field [0001] The present application relates to the field of data interaction, and in particular to a method, device and medium for stealthy inquiry. Background technique [0002] With the rapid development of big data and artificial intelligence in recent years, the increasingly strict protection of user data privacy and security management will become a global trend. For data query and interaction between enterprises, the data owner provides data to the query party for query. How to protect the privacy of the entire query process, so that the data owner cannot know the query target of the query party, but can return smoothly The query results are given to the query party, and the query party cannot obtain data content other than the data information it queried. This is an industry pain point and problem that needs to be solved. [0003] The traditional stealth query is mainly realized by the technology of inadvertent transmission. The data owner sends multiple ...
