A method, device, and verification method for electronically encoded data

Abstract

The embodiment of the invention provides an electronic coded data generation method, an electronic coded data generation deice, an electronic coded data verification method, and an electronic coded data verification device. The electronic coded data generation method comprises the steps of respectively generating a range bit, a sequence bit and a random bit of electronic coded data according to a preset range bit factor, a preset sequence bit factor and a preset random bit factor; splicing the range bit, the sequence bit and the random bit of the electronic coded data into a plaintext numeric string according to a set sequence of the range bit, the sequence bit and the random bit; encrypting and displacing the plaintext numeric string to generate an encrypted ciphertext numeric string; generating a check bit number with the specified bit according to the encrypted ciphertext numeric string, computing an interposition position of the check bit, interposing the check bit number into the encrypted ciphertext numeric string, thus generating the electronic coded data. According to the methods and devices provided by the invention, generation efficiency of an electronic coupon is greatly improved, capacity of the coupon is enhanced, and the break difficulty of the electronic coupon is increased.

Description

technical field [0001] The present invention relates to the technical field of digital security, in particular to a method and device for generating electronically coded data, and a verification method and device. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the development of Internet finance, there are more and more transaction forms using electronic coupons as the medium. As the unique identification of electronic coupons, electronic coupon codes have been used as passwords for direct consumption in some fields, so electronic coupon codes encode them There are very high requirements in terms of rules and verification modes. At present, most of the electronic coupon code generation methods in the industry are generated by means of random numbers, etc., but thi...
