Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0024] Such as figure 1 As shown, the embodiment of the present invention provides a desensitized data comparison method based on an asymmetric algorithm, including the following steps:

[0025] S1. Use an asymmetric encryption algorithm to encrypt the batch source data one by one to obtain the desensitized benchmark data. The encryption operation is completed through the encryption card, and the encryption key uses the built-in key of the encryption card, and the two sets of encryption keys of the asymmetric encryption algorithm key pair One of the groups in the key has been destroyed beforehand...

Abstract

The invention discloses a desensitization data comparison method and device based on an asymmetric algorithm. The method comprises the following steps: firstly, asymmetric algorithm encryption is performed on source data by using an asymmetric key damaged in advance; therefore, the encrypted data cannot be decrypted; the encryption process depends on specific encryption hardware; the encrypted data cannot be enumerated on a large scale; violent restoration is performed by means of collision and the like; when data comparison is carried out; if so, the same encryption processing is performed onthe to-be-compared data; the processed to-be-compared data is compared in the reference data; Such a comparison method, According to the technical scheme, the hackers can acquire the real content ofthe source reference data without any technical means even if the hackers steal the complete desensitization reference data through illegal means, so that the confidentiality of the source reference data is fundamentally guaranteed, and various confidential data can be applied to more informationized scenes needing timely data comparison.

Description

technical field [0001] The present invention relates to the field of data security, especially confidential data, private data, sensitive data and other confidential data that cannot be published or leaked. When used as reference data for data comparison applications, the reference data must be irreversibly A method for accurate comparison of data under the premise of desensitization. Background technique [0002] In the field of informatization data application, due to its security sensitivity, confidential data always has great constraints in application. Even if it is a simple comparison based on confidential data, it is difficult to implement the comparison process due to the requirements of security level division. It is heavy and inefficient. In many application scenarios, the comparison process cannot meet the real-time requirements of actual combat, and the value of confidential data comparison is greatly reduced. [0003] At present, there are mainly two modes for ...
