Embodiment Construction

[0059] The following describes exemplary embodiments of the present invention with reference to the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and should be regarded as merely exemplary. Therefore, those of ordinary skill in the art should realize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Likewise, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0060] In order to better protect user data privacy and query privacy, the embodiments of the present invention split the key and value into multiple segments based on the key-value data based on the separation of the key and the key value. Then publish these segments to different cloud storage service providers, so as to ensure that any independent cloud storage servi...

Abstract

The invention provides data storage and query methods and apparatuses, an electronic device and a readable storage medium. The calculation overhead of a cloud storage service provider and a user end can be greatly reduced; data privacy and query privacy of a user can be better protected; and the data query efficiency is improved. The data storage method comprises the steps of splitting a key nameand a key value of a key-value pair into a key name section and a key value section, and generating a unique random number to correspond to the key-value pair data; and associating the random number with the key name section and the key value section and sending the random number to a specified server for performing storage.

Description

Technical field [0001] The present invention relates to the technical field of computers and computer software, and in particular to a method, device, electronic equipment and readable storage medium for data storage and query. Background technique [0002] In the cloud storage environment, users need to upload data to the cloud storage service provider and save it in the cloud server. At this time, because the data is out of the user's control, the security of the data cannot be ensured. [0003] From the perspective of users, their demands for privacy protection mainly include the following two points: one is data privacy, that is, users need to ensure that the data they upload is protected by security; the other is query privacy, that is, users need to ensure that the queries they submit The content could not be recognized. [0004] In order to protect the privacy of users, cloud service providers generally first encrypt the user’s original data set to obtain the ciphertext W, an...
