Embodiment Construction
[0065] The invention uses the biometric information of the user carried in the legal certificate as a sample to encrypt and decrypt the services handled by the user. The biometric feature information may specifically be fingerprint feature information or portrait feature information. The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0066] figure 1 It is a flow chart of Embodiment 1 of the business information encryption method provided by the present invention. In this embodiment, the sample used is fingerprint feature information, that is, the first biometric feature information is specifically fingerprint feature information. Such as figure 1 As shown, the method includes the following steps:
[0067] Step 101, read the user's fingerprint feature information from the ID card.
[0068] The core processing software in this embodiment can be installed in a host comp...

The invention discloses a business information encryption and decryption method and device, and belongs to the technical field of information processing. The business information encryption method comprises the following steps: acquired first biometric feature information of a user is compared with first biometric feature information read from an ID card, and a first comparison result is obtained; if the first comparison result is verified, the user is permitted to handle a business until the business is completed; an acquired first secret key is applied to conduct a digital signature on business information, and digital signature information is put on a first presupposed position of business information; and an acquired second secret key is applied to encrypt acquired first biometric feature information of the user and the first comparison result, and biometric feature cipher text information is put on a second presupposed position of business information. According to the business information encryption and decryption method and device, biometric feature information is applied to encrypt information of business handled by the user. When controversies like a problem in handling the business or a tamper in business information occur, corresponding decryption methods can be applied to solve the controversies.
Description
technical field [0001] The present invention relates to the technical field of information processing, and more specifically, to a business information encryption and decryption method and device. Background technique [0002] In recent years, with the expansion of banking business and mobile communication business, illegal activities using forged or counterfeit identity information are increasing, which not only causes huge economic losses, but also affects social stability. For example, when a user goes to a bank or a mobile communication business hall to handle business, he generally verifies his identity by presenting his ID card. As for the authenticity of the ID card or whether the ID card holder is himself, it generally depends on manual judgment. Basically, it is judged by manually comparing the appearance of the ID card holder with the photo on the ID card, and manually comparing the ID card number with the ID number in the system. This method is very random and unc...
