Data identification method for two-dimension code safety verification

Abstract

The invention discloses a data identification method for two-dimension code safety verification. The method comprises the following steps of S1, adding a verification code in a character random code to form a byte stream random number, and performing data encryption and data conversion to form a verification random code; S2, combining the verification random code and a URL (Uniform Resource Locator) to form a background visit address, and generating a two-dimension code with the background visit address; S3, scanning the two-dimension code to obtain the verification random code and the URL, restoring the verification random code through decryption to form the character random code and the verification code, and generating a new verification code according to the character random code; and S4, comparing the verification restored by decryption and the new verification code, returning a message of verification failure if the verification restored by decryption and the new verification code are not consistent, and performing next verification operation of the verification restored by decryption and the new verification code are consistent. The method provided by the invention can effectively prevent influences of brute force attack, can prevent database paralysis caused by lots of data access, and can improve the safety of the two-dimension code to a certain extent.

Description

technical field [0001] The invention relates to a data forgery verification method, in particular to a data forgery verification method for two-dimensional code security verification, and belongs to the technical field of anti-counterfeit verification. Background technique [0002] The two-dimensional code is automatically read by image input equipment or photoelectric scanning equipment to realize automatic information processing. It is an important entrance of the mobile phone. Through the two-dimensional code, the mobile phone can quickly access the Internet. With the application of QR codes, various QR code-related products have also emerged in large numbers, such as QR code electronic tickets, QR code vouchers, QR code payment, QR code anti-counterfeiting, QR code traceability, QR code code points, etc. More and more QR codes are applied to fast-moving consumer goods. QR codes are applied to every can of milk powder and every bottle of mineral water. And when two-dime...

Problems solved by technology

However, if it is a 100% winning lottery or a large-scale high-value reward lottery, many people may use brute-force cracking programs, that is, specially compile a simulation program, and try to use the program to crack random codes to obtain benefits. In the above-mentioned random code encoding method, the database needs to be queried every time a user accesses. When someone cracks the random code violently, it will cause a large number of database accesses in an instant, thus easily paralyzing the database server.

If you use an operation method similar to that of a desktop computer and let users enter the verification code every time, it will greatly affect the user experience, reduce user satisfaction and participation enthusiasm
