Problems solved by technology

If the corporate seal is stolen or used by others, it is likely to bring unnecessary disputes and responsibilities that the company cannot bear
[0003] Most of the seals currently used are anti-counterfeiting by setting textures on the seal frame and using anti-counterfeiting fonts on the seals. The seals made in this way are relatively easy to be forged, and the information of the stamped document cannot be recorded in the seal. It is also very difficult to verify the authenticity of seal documents and the authenticity of seals

Embodiment 1

[0066] Such as figure 2 As shown, the seal of the present invention includes circle, ellipse and square, and the seal frame that present embodiment adopts is circular, and a kind of encrypted seal that present embodiment provides, comprises picture and text area 110, seal frame 120 and bar figure Encryption area 130, picture-text area 110 and bar-shaped digital encryption area 130 are all arranged in seal frame 120, and in the bar-shaped digital encryption area 130, be filled with encryption code, the shape of the bar-shaped digital encryption area of ​​the present embodiment is strip in addition When receiving the seal request, the encryption code is generated, and the seal information of the stamped file is loaded on the encryption code. Different seal files will correspond to different encryption codes. In addition, the bar-shaped digital encryption area 130 A blank area is set between the graphic area 110 and the stamp frame 120 .

[0067] The encryption codes of the pre...

Embodiment 2

[0089] Such as Figure 8 As shown, the difference between the present embodiment and Embodiment 1 is that what the bar-shaped digital encryption area adopts is an arc-shaped digital encryption area, and the enciphered code-colored stamp frame 120 in the bar-shaped digital encryption area is arranged in an arc, which can satisfy different requirements. The requirements of customers or different requirements for the shape vision of the encrypted area.

Embodiment 3

[0091] Such as Figure 10 As shown, the difference between this embodiment and Embodiment 2 is that the encryption code in the bar-shaped digital encryption area 130 adopts a character string formed by a combination of numbers and letters. In this embodiment, the stamping information of the stamped document is recorded in the string of "FD16414F123184FSS15", and the steps for secondary encryption are as follows:

[0092] Obtain the string to be processed, including obtaining the pixel information of the string to be processed;

[0093] Split the character string to be processed, randomly select a position on the string as the split point and record the position information of the split point. In this embodiment, the randomly selected split point is located between the 10th character "5" and the 11th character Between characters "F", such as Figure 4 with Figure 5 As shown, the string to be processed is split into a first segment 131 and a second segment 132 to form two se...

Abstract

The invention discloses an encrypted seal and a bar-shaped data secondary encryption method. The encrypted seal comprises an image-text area, a seal frame and a bar-shaped digital encryption area, the image-text area and the bar-shaped digital encryption area are both arranged in the seal frame, the bar-shaped digital encryption area is filled with an encryption code, the encryption code records the stamping information of a stamped file, different sealed files correspond to different encryption codes, and the bar-shaped digital encryption area is arranged in a blank area between the image-text area and the seal frame; and the bar-shaped data secondary encryption method comprises: obtaining a bar code or a character string to be processed, splitting the bar code or the character string to be processed and re-splicing two segment codes with missing information. By arranging the bar-shaped digital encryption area, the seal can be subjected to anti-counterfeiting encryption, and the authenticity of the seal and a sealed file can be conveniently checked; and through secondary encryption of the bar-shaped data, other people can be prevented from directly reading information of the bar-shaped data, so that the security of the bar-shaped data is higher.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeit seals, in particular to a secondary encryption method for encrypted seals and bar-shaped data. Background technique [0002] The corporate seal is proof of the power of the corporate identity. A document with the corporate seal is a valid document protected by law, and it means that the company bears legal responsibility for the content of the document. If the corporate seal is stolen or used by others, it is likely to bring unnecessary disputes and responsibilities that the company cannot bear. [0003] Most of the seals currently used are anti-counterfeiting by setting textures on the seal frame and using anti-counterfeiting fonts on the seal. The seals made in this way are relatively easy to be forged, and the information of the stamped document cannot be recorded in the seal. It is also very difficult to verify the authenticity of the seal document and the authenticity of the seal. ...
