TWO-DIMENSIONAL CODE-BASED FILE ACQUISITION METHOD AND DEVICE AND TWO-DIMENSIONAL CODE GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/051757
Kind Code:
A1
Abstract:
The present invention relates to the field of data identification, and in particular to two-dimensional code technology. Provided in the present invention is a two-dimensional code-based file acquisition method, comprising: step 1, parsing a two-dimensional code to acquire two-dimensional code encoded data, wherein the encoded data comprises a first unique value, encrypted data, and signature data; step 2, verifying the signature data; step 3, decrypting the encrypted data to acquire a file address and an nth data segment ln; step 4, acquiring an encrypted file according to the nth data segment ln and the file address; step 5, verifying the encrypted file according to the first unique value to acquire a decrypted file. The present invention solves the technical problems of easy tampering and poor security when data is stored and acquired on the basis of a two-dimensional code, and implements secure and reliable information protection.
