Definitions
- the present invention relates to graphics recognition and file security techniques, and more particularly to a method of further adding signatures to stamps. Background technique
- Such patterns are generally fixed, such as: the totem of primitive society, the family crest of Western society, and the seals and signatures of people's politics and business activities.
- this stamp is only a single function of the above-mentioned "individual” or “legal person”.
- this stamp pattern does not reflect the content characteristics of a particular document with each use.
- the present invention provides a method of attaching a computer data mark to a stamp during use of the stamp, which can be made not only as an individual or an organization in the file processing of a modern computer office.
- the function of the identity mark of the group, etc. and enables the stamp to reflect the computer data characteristics associated with the file content each time it is used.
- the marking method of the stamp according to the present invention includes, when the stamp is used, attaching a data symbol or symbol string that the computer can process to the stamp pattern.
- the symbol or symbol string is a computer binary or hexadecimal data string used to mark the data characteristics of each signed file content of the same stamp pattern. 'When using a graphic stamp indicating exclusive rights and credits, it marks the characteristics of a document content used for each signature, which can effectively prevent the falsification of the pattern stamps and their documents that represent the exclusive rights and credits of others.
- Figures 1 and 2 show a schematic representation of a stamp pattern before and after the method of the present invention. detailed description
- this binary data string is converted into a readable and recognizable hexadecimal character.
- the binary data string is calculated by the computer based on the contents of the file signed by the signature indicating the exclusive right and the credit, for example, using a hash function in the digital signature. In addition, you can continue to convert this binary data string into a hexadecimal number and wait for it.
- the position of the data stamp can be written to the position of the data, and the data of the first step is superimposed on the determined position area.
- the data can be miniaturized or color-like color-valued to maintain the geometry and appearance of the original pattern stamp.
- the computer electronic file that signs the stamp is saved, or the document is printed into a paper-like physical form using a computer-controlled digital printing device.
- the fourth step after receiving the file with the above stamp, recalculating the file content using the same algorithm as generating the binary data string, generating a binary data string, and comparing the obtained data string with the additional data string in the stamp pattern. , when the results are consistent, it can be confirmed The document signing the above stamp is true.
- Figures 1 and 2 show a schematic representation of a stamp pattern before and after the method of the present invention.
- the 40-bit hexadecimal number indicated by reference numeral 2 in Fig. 2 is obtained by converting the 160-bit binary data generated by the method of the present invention.
- the amount of data of the binary number can be not limited to 160 bits.
- the displayed position may not be limited to the position shown in the drawing.
- the file object used by the stamp pattern can be marked to clearly know the authenticity of the specific file content data each time the stamp pattern is used, and to prevent the falsification of the pattern stamp indicating the exclusive right and credit of others and the behavior of the file.
