Encrypted two-dimensional code with traceability and anti-counterfeiting functions

The invention relates to the technical field of two-dimensional code data identification, specifically to an encrypted two-dimensional code with traceability and anti-counterfeiting functions. The encrypted two-dimensional code comprises an encrypted code. A traceability system of the encrypted two-dimensional code comprises an encryption module, an information processing module, a judgment module, a storage module and a decryption module. The encrypted two-dimensional code of the invention has the beneficial effects that identity discrimination is added on the basis of existing two-dimensional code data, so the appearance and fingerprint data of an identifier are synchronously acquired, the identity of a data extractor is determined, embezzlement and fraud are prevented, and the securityof file information is greatly improved; and by arranging the storage module, a group of data for generating a public key signal is packaged and stored, so subsequent information extraction is facilitated, the purpose of trac
