Embodiment Construction

[0024] It is easy to understand that, according to the technical solution of the present invention, those skilled in the art can propose multiple structural modes and implementation modes that can be replaced without changing the essence and spirit of the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the entirety of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0025] It should be understood that self-interpretation refers to a property of information that can explain itself by itself. When we construct the coupon code, we will compile the validity period of the coupon code, the code of the coupon code, the serial number of the coupon code, the supplier identification code, the agent identification code, and the production date of the coupon code into the coupon code.

Abstract

The present invention proposes a construction method, decryption method and device for self-explanatory encrypted coupons. The construction method includes: acquiring rights and interests information and user information, and the rights and interests information includes coupon code serial numbers; , convert the coupon code serial number to generate a key; use the key to encrypt the rights and interests information to generate ciphertext information; use the user information to sign the ciphertext information to generate a signature Information; after combining the coupon code serial number, ciphertext information and signature information, the coupon code of the card coupon is generated. In the present invention, the card coupon supplier does not need to store a large number of coupon codes and personal information, but only needs to store its own key generation rules, and can correctly verify the authenticity of the coupon code provided by the user, which solves the problem of being unable to verify when the system loses data Whether the coupon code provided by the user is real or not.

Description

technical field [0001] The present invention relates to the technical field of information encryption, in particular to a construction method, a decryption method and a device for self-explanatory encrypted coupons. Background technique [0002] A coupon is an (electronic) card that contains a card number and a code or just a random string of characters (coupon code). The codes of traditional coupons are random, and it is difficult for users to find out the real codes of coupon suppliers through exhaustive enumeration. [0003] However, the card coupon supplier is bound to store some additional information in the system, such as information about the beneficiary of the distributed coupon code. Once the coupon provider stores this personal information, it must fulfill its responsibility to protect this information and prevent personal information from being leaked. [0004] In addition, the traditional method of generating coupons is that the system randomly generates a ser...
