Problems solved by technology

[0003] In recent years, lawbreakers have been fraudulently forging and tampering with official government documents and legal documents by privately engraving fake official seals. Some ordinary people receive such fake documents. Paper "official documents" will credulously trust criminals, thus causing unnecessary property losses to oneself. Therefore, it is imperative to take effective measures to crack down on criminals and not give them opportunities to protect the interests of the people.
On the other hand, the transmission and verification of official documents between government departments has always been troubled by relevant departments. 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

Embodiment

[0049] Taking the document system of a Civil Affairs Bureau as an example, see image 3 , the specific process is broken down as follows:

[0050] 1. The document inspection system extracts the document content (full text or key information), such as a marriage certificate document, the content is:

[0051] Document content: After verification, Zhang San (ID number: ...) has no marriage registration record in this bureau. January 2, 2013.

[0052] 2. Add the timestamp to form the document source code:

[0053] Document content: After verification, Zhang San (ID number: ...) has no marriage registration record in this bureau. January 2, 2013. Timestamp: 20130102102930345

[0054] The purpose of adding timestamps is to distinguish them because the content in a large number of documents may be the same;

[0055] 3. The original code of the document is generated by the MD5 digest algorithm to generate the system's unique inspection code: 9793D936104A48D42035718DB95E9A02;

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.
