Embodiment Construction

[0040] Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure and features provided by the present invention are described in detail as follows:

[0041] The meaning of screen coding is: at least one form of images, characters, symbols, and background forms is printed on a recording medium, and the content printed on the medium is composed of physical characteristics including geometry The different dot shapes of different dots are replaced by the screen dots formed according to the given arrangement rules. This method constitutes the screen code for embedding information in the printed content. Its dot shape can be composed of more than one different geometric characteristics, such as: the shape, size, position and direction of the dot; the dot shape can also be composed of more than one different physical characteristics. The form of dots formed, such as: dots with different modulation methods, dots with differen...

Abstract

The equipment embedding message in printed words using shielding coding relates to message embedding part and message identified part. The front part relates to embedding message dispose module, document dispose module, shielding coding embedding module and print output module. The latter part relates to scan input module, shielding coding identify module, data display module. The two parts make into the information recording equipment on the print words. It mainly uses to the pursuit of the lost paper and the attempt of paper document. When print the common paper, embed the printer, print time and message of print machine to the print words. Once the message is lost, it can help related department to find out the trench of lost paper and can be the gist of paper authenticity.

Description

technical field [0001] The invention relates to a computer information processing device for recording and identifying computer information in the form of graphic codes on the text of a printing medium, that is, a screen coding file tracing device. Background technique [0002] With the development and application of new materials and technologies, as the carrier of data information recording, it has developed from the initial paper medium carrier to magnetic, optical media and memory. However, paper still has an irreplaceable role as an information carrier. After the "Paperless Movement" was promoted for more than ten years, its use has not decreased, but has maintained an annual growth rate of 10%. The annual sales of millions of printers and tens of millions of printers / copiers are evidence of this fact. Paper documents are original, empirical, intuitive, function as legal documents, financial asset certificates, security, durability, etc., all of which cannot be replac...
