3 results about "Hard copy" patented technology

A method, computer program product, and computer system are provided for document annotation processing. The method includes: providing a target document in a digital format; receiving an image of an annotated hard copy of the target document and extracting annotations from the image as an annotation source; processing the extracted annotations to collect extracted annotation information metadata for the image; merging the extracted annotation information metadata for the image with other extracted annotation information metadata from other annotation sources for the target document to generate master annotation metadata; and providing the master annotation metadata for application to the target document.

The present application relates to the technical field of image hard copy reproduction, in particular to a reversible halftone method and system based on dynamic noise, comprising: constructing a reversible halftone model, including a halftone generation network and a recovery network; passing the original color image through the halftone generation network of the reversible halftone model, outputting a reversible halftone image; and passing the reversible halftone image through the recovery network, outputting a recovered color image. The present application improves the quality of the halftone image, improves the detail accuracy and color restoration degree of the reversible halftone image, ensures that the recovered color image reflects all details and color ranges of the original color image as much as possible, and improves the image processing efficiency.

This invention relates to the fields of information security and printing technology, specifically to an information printing output control and traceability method based on a TCM trusted computing module. The method includes an information printing output control and traceability system comprising: a client with a trusted identity module for collecting and encrypting the printing user's identity information; and a printer with a trusted computing module for verifying its own and its operating environment's trustworthiness, securely storing the root key, performing cryptographic verification and decryption of received encryption tasks, executing "human-to-release" logic control, and generating and embedding traceability information into the printing medium for verifying trustworthiness. Compared with existing technologies, this method establishes an immutable trust chain, achieves end-to-end cryptographic guarantees from digital authorization to physical release, and ensures that each output hard copy has a verifiable and unique identity, preventing the risk of data leakage due to residual data.
