AI Technical Summary

Technical Problem

Existing printing, stamping, and scanning technologies lack the ability to deeply perceive the characteristics of physical media, resulting in insufficient stamping positioning accuracy, difficulty in identifying the authenticity of seals, and insufficient ability to prevent tampering and trace archived documents.

Method used

Dynamic stamp target coordinate matrix is ​​generated by semantic segmentation of the page layout and pre-compensation of geometric deformation. Data is collected by combining multispectral alternating illumination and photometric stereo method. Seal anomaly assessment is performed using twin network. High-fidelity target archive file is generated by multi-band fusion of Laplace pyramid. Byte hash fingerprint and paper fiber speckle features are extracted for dual traceability and anti-tampering.

Benefits of technology

It enables precise positioning of the stamping location, accurate identification of the authenticity of the seal, and efficient anti-tampering and traceability of archived documents, thereby enhancing the perception and control capabilities of the physical media characteristics throughout the entire process.
