摘要： The present invention relates to [a copy protection method for documents and belongs to the technical field of security document protection. In the prior art, important documents, especially classified documents, are generally prohibited from copying by their owners due to security. However, the current technology still unable to fundamentally resolve the issue of illegal copying of classified documents. The method of the present invention is to form an authentication shade underneath the original image. By using a program built in a copy apparatus, whether mark is in the document is determined, so the document could be copied legally. The method of the present invention can detect the watermark within a document quickly and accurately so as to fundamentally stop unauthorized copying of copy-protected documents. As a result, the security of the classified documents is improved greatly. Moreover, the method is easy to implement and no extra hardware storage space is needed.

摘要： The present invention relates to a method for producing halftone dots in the field of image hard copying, more particularly to a method for frequency-modulation screening using error diffusion based on dual-feedback. In the known frequency-modulation and amplitude-modulation screening technology, it is hard to output a halftone image with high quality using an output equipment with a low resolution (600 dpi) and the satisfactory effect of representing the gradations of the original image in detail and holding the smoothness of the original image can not be achieved. By using the dual-feedback technology based on a basic algorithm of the error distribution, the method in the present invention realizes the organic combination of the conventional frequency-modulation and amplitude-modulation screens and achieves the effect of mixed screening. The method in the present invention can effectively solve the problem of losing gradations of dots in an output equipment with low resolution and can reduce the moire caused by the random distribution characteristic so as to output halftone images with high quality and full gradations.
