Abstract

The embodiment of the invention discloses a privacy protection query method and device supporting outsourcing computing and related equipment, and the method comprises the steps: receiving P keywords, classifying the P keywords to obtain Q types of keywords, and enabling each type of keywords to correspond to a bucket ID; sorting the Q-class keywords according to the bucket ID; public parameters of each type of keywords in the Q types of keywords after sorting are determined, Q groups of public parameters are obtained, and each group of public parameters corresponds to one bucket; the Q groups of public parameters are sent to the server side, corresponding buckets are called for query through the server side according to the Q groups of public parameters and the corresponding sequence, a first query result is obtained, and each bucket is used for storing a mapping relation between a preset keyword and local data; and receiving a first query result fed back by the server, performing decryption operation according to the first query result to obtain a second query result, and feeding back the second query result to the client. By adopting the embodiment of the invention, the hidden trace query efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a privacy protection query method, device and related equipment supporting outsourced computing. Background technique [0002] In practical applications, the stealth query technology mainly refers to protecting the data privacy of the inquiring party when performing data retrieval based on keywords, that is, initiating a query to the inquired party without revealing the content of the keywords to be queried by the inquiring party. Data query, at the same time, the queried party should return the correct query result without knowing the content of the keyword. During the process of anonymous inquiry, the inquiring party should not obtain other relevant information except the content of the data to be queried. The stealth query protocol can be considered as a specific application of the secure multi-party computing protocol in a specific scenario. At present, the...
