Data collision method and device, storage medium and electronic equipment

Abstract

The invention relates to the technical field of computers, in particular to a data collision method and device, a storage medium and electronic equipment. The method comprises the following steps: encrypting first original data by using a first key according to a preset exchangeable encryption algorithm to obtain first encrypted data; acquiring second encrypted data, wherein the second encrypted data is obtained by encrypting the second original data by using a second key according to an exchangeable encryption algorithm; encrypting the second encrypted data by using the first key according toan exchangeable encryption algorithm to obtain third encrypted data; acquiring fourth encrypted data, wherein the fourth encrypted data is obtained by encrypting the first encrypted data by using thesecond key according to an exchangeable encryption algorithm; and obtaining an encrypted data intersection of the third encrypted data and the fourth encrypted data, and determining an original dataintersection of the first original data and the second original data based on the encrypted data intersection. According to the method, data collision can be completed under the condition of protecting private data from being leaked.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a data collision method, a data collision device, a computer-readable storage medium, and electronic equipment. Background technique [0002] Privacy data generally refers to relatively sensitive data that needs to be protected in each enterprise, such as business secrets, intellectual property rights, key business information, business partner information, and user data. When conducting a business cooperation with other companies, using this part of data can generate great business value, but for the purpose of privacy data protection, this part of data often cannot be transmitted to the other party in plain text, when some businesses require privacy data of both parties During data collision, this part of business functions cannot be realized. At present, there are usually two methods for processing private data such as user information and device numbers: [0...
