Abstract

The invention relates to a transcoding anti-fake seal and a transcoding anti-fake method. The transcoding anti-fake seal comprises a seal body and a sealing face; a containing bin is arranged at the bottom of the seal body buckled on the sealing face; a PCB (printed circuit board) and a transcoding mechanical device are arranged in the containing bin; the PCB is electrically connected with the transcoding mechanical device; the transcoding mechanical device is controlled by the PCB to transfer a document number of a document needing to be sealed; the sealing face comprises a code displaying region for displaying the document number expressed by the transcoding mechanical device. When the transcoding anti-fake seal is used for sealing, the dynamically changed document number is sealed on the document together with an original pattern of the seal to form a seal impression for checking. The impression seal for checking can be identified by checking a database without the need of submitting to a professional identifying agency, authenticity identification is facilitated, the cost is reduced, and economic loss caused by counterfeiting of important files such as a contract is avoided.

Description

technical field

[0001] The invention relates to the field of anti-counterfeiting seals, in particular to a code-changing anti-counterfeiting seal and a code-changing anti-counterfeiting method. Background technique

[0002] At present, due to the improvement of computer image processing, laser engraving, laser scanning and printing technology, counterfeiting seals has become quite easy, and the counterfeit seals are also extremely realistic, and ordinary users cannot distinguish their authenticity, which leads to the proliferation of fake contracts. suffered huge economic losses.

[0003] In addition, the management and monitoring technology for seals in the existing technology is far from meeting the needs of seal management. The use of seals cannot be tracked anytime and anywhere. Effective supervision of unregistered seals.

[0004] It can be seen from the above that the misuse of genuine seals without monitoring, and the forging of fake contracts with fake seals have b...

Examples

Embodiment 1

[0044] Such as figure 1 As shown, a code-changing anti-counterfeiting seal includes a printed body 1 and a printed surface 2. There is a storage compartment 4 at the bottom of the printed body 1, and the printed body 1 is buckled on the printed surface 2; the printed body 1 also includes a PCB circuit board 5 and a code-changing mechanism. The device 6, the PCB circuit board 5 and the code-changing mechanical device 6 are arranged in the storage compartment 4, the PCB circuit board 5 and the code-changing mechanical device 6 are electrically connected, and the PCB circuit board 5 is controlled by sending an electrical signal to the code-changing mechanical device 6 Code-changing mechanical device 6 runs out the file code that needs to stamp the file.

[0045] Such as figure 2 As shown, the seal surface 2 includes a code display area 3, and the code display area 3 is used to display the document code represented by the transcoding mechanism 6. The code display area 3 is a di...

Embodiment 2

[0059] Such as figure 1 As shown, a code-changing anti-counterfeiting seal includes a printed body 1 and a printed surface 2. There is a storage compartment 4 at the bottom of the printed body 1, and the printed body 1 is buckled on the printed surface 2; the printed body 1 also includes a PCB circuit board 5 and a code-changing mechanism. The device 6, the PCB circuit board 5 and the code-changing mechanical device 6 are arranged in the storage compartment 4, the PCB circuit board 5 and the code-changing mechanical device 6 are electrically connected, and the PCB circuit board 5 is controlled by sending an electrical signal to the code-changing mechanical device 6 Code-changing mechanical device 6 runs out the file code that needs to stamp the file.

[0060] Such as image 3 As shown, the seal surface 2 includes a code display area 3, and the code display area 3 is used to display the document code represented by the transcoding mechanism 6. The code display area 3 is a dia...
