A document encryption transmission method based on two-dimensional barcode technology

Abstract

The invention relates to a file encryption transmission method based on a two-dimensional bar code technology. According to the method, digital signature is carried out on file contents with legal force, encryption is carried out on information to be encrypted by utilizing a public key encryption algorithm, then check codes, the file contents, digital signatures and cryptographs are added in according to needs and form two-dimensional codes to be added to corresponding files, a receiver extracts corresponding information from the two-dimensional codes by utilizing smart devices like smart phones to achieve simple interaction operation with a file system, and therefore truth and integrity of the corresponding files can be checked. In addition, local one-time check can be achieved through the file digital signatures in the two-dimensional codes, the cryptographs in the two-dimensional codes can be encrypted by utilizing the corresponding public key encryption algorithm, and therefore safe transmission of information can be achieved.

Description

technical field [0001] The invention relates to two-dimensional barcode technology, in particular to a document encryption transmission method based on two-dimensional barcode technology. Background technique [0002] In recent years, lawbreakers have been fraudulently forging and tampering with government department documents and legal documents by privately engraving fake official seals. Some ordinary people receive such fake documents. Paper "document" will credulous criminals, thus causing unnecessary property losses to oneself, therefore, it is imperative to take effective measures to crack down on criminals, not to give them an opportunity, and to protect the interests of the people. On the other hand, the transmission and verification of documents between government departments has always been troubled by relevant departments. The reason is that the certificate of the document can only be proved by the official seal, and the forgery of the official seal is easy to con...

[0002] In recent years, lawbreakers have been fraudulently forging and tampering with government department documents and legal documents by privately engraving fake official seals. Some ordinary people receive such fake documents. Paper "documents" will credulous criminals, thus causing unnecessary property losses to themselves, therefore, it is imperative to take effective measures to crack down on criminals, not to give them opportunities to protect the interests of the people

On the other hand, the transmission and verification of documents between government departments has always been troubled by relevant departments. The reason is that the certificate of the document can only be proved by the official seal, and the forgery of the official seal is easy to confuse the real ones, and effective identification cannot be carried out, resulting in The authenticity, integrity and non-repudiation of documents cannot be guaranteed, and when something goes wrong, there will often be an irreversible situation

In addition, because most of the documents are printed on paper in plain text, some data that needs to be kept secret may be leaked easily, causing losses to the parties concerned
