Ciphertext intersection method and device based on Hash algorithm and readable storage medium

Abstract

The invention discloses a ciphertext intersection method and device based on a Hash algorithm and a computer readable storage medium, and the method relates to the technical field of communication, and comprises the steps: receiving a data set uploaded by a user, carrying out the racking of a field which can be intersected, carrying out the encryption of the field which can be intersected after the field which can be intersected is racked, and carrying out the encryption of the field which can be intersected. And obtaining a first encryption result, determining a first Hash value of the first encryption result according to a Hash algorithm, and uploading the first Hash value to the platform. It can be seen that when the user uploads the field which can be intersected, the data is encrypted firstly, then the Hash algorithm is carried out on the encryption result, the Hash value is obtained, and then the Hash value is uploaded, so that a layer of guarantee is added to the safety when the user uploads the data, the corresponding data cannot be obtained from the Hash value even if the data is stolen, and the user experience is improved. The risk that the uploaded data is leaked when the user wants to exchange is avoided, and the experience feeling of the user is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method, device, and computer-readable storage medium for ciphertext intersection based on a hash algorithm. Background technique [0002] With the development of the data age, people are paying more and more attention to personal privacy, and everyone is more and more aware of privacy protection. In order to meet the query of some private data, the ciphertext technology has been widely used in the medical field, such as marriage Before doing pre-marital examinations to understand each other's physical conditions, but at the same time checking the genetic medical history, people are reluctant to let others know their genetic medical history, and the current cipher text seeking technology usually focuses on the security and openness of gene bank data. Since the current ciphertext intersection technology pays attention to the security and openness of the ge...

Problems solved by technology

Since the current ciphertext submission technology focuses on the data security and openness of the gene bank, but ignores the security of the data uploaded by the user during submission, it is easy to cause the risk that the user's data list will be leaked during the data submission process.
