Description

The electronic information method is hidden in polymorphic digital coding on the bearing medium
Technical field
Technical field such as the invention belongs to that computerized information is hidden, information anti-fake, information read.Relate to the hiding electronic information method of polymorphic digital coding on the bearing medium.
Background technology
Along with the development of China's economic technology, the computer document treatment capacity significantly increases, and electronic document and the document process amount on bearing medium such as paper also significantly increase; In some field, electronic document and the document on bearing medium such as paper are more and more obvious with the shortcoming of two media storage, like the problem of management of document on the electronic document of personal file data and the paper; Should manage electronic document; Managed document on the paper again, and wanted and can search each other, cumbersome.Therefore on bearing medium, showing two kinds of documents simultaneously becomes very important.
The situation that the information of imbedding simultaneously in printer prints is arranged is at present abroad come the date printed of recording user document and the sequence number information of time and printer like the company of Fuji-Xerox of Japan through on paper, imbedding yellow dot matrix code simultaneously in file printout.But this method only is limited to color printer, and the quantity of information of imbedding is few.Causing and imbedding few reason is owing to code block and literal, figure, the picture overlapping of encoding, and coding can not effectively be discerned, and therefore through in bearing medium, the same coding buried multipass, solves overlap problem.
How not only solve overlap problem but also solve the problem of information buried amount, content of the present invention just.
The technical scheme that the present invention adopted is:
The electronic information method is hidden in polymorphic digital coding on the bearing medium, comprises the formation part and the identification division of polymorphic digital coding, it is characterized in that: the formation method step of the formation part of polymorphic digital coding is following:
(1) select for use contain the different directions observation state different or in the extraneous factor excitation different directions observation state is different or at extraneous factor excitation state different dyeing material (different directions is observed here, different directions observation and extraneous factor encourage the abbreviation situation under the extraneous factor excitation) down down;
(2) electronic information is expressed as the basic Serial No. of polymorphic digital coding;
(3) on bearing medium, represent the basic Serial No. of polymorphic digital coding with the coloring material elementary cell that contains the changed condition state variation, its method is to represent in the basic Serial No. of polymorphic digital coding digital basically with a plurality of states that contain this coloring material elementary cell or one or more state variation;
(4) obtain being embedded with the polymorphic digital coding of electronic information;
The recognition methods step of the identification division of polymorphic digital coding is following:
(1) to the scanning of polymorphic digital coding through different directions, photograph or the extraneous factor excitation down different directions scanning, photograph or obtain the data to be identified under the polymorphic digital coding difference situations on the above bearing medium in different extraneous factor excitation scanning down, photograph;
(2) data to be identified of the different situations of identification; Obtain comprising under the corresponding situation state of the state of coloring material elementary cell, obtain corresponding basic digital this numeral of sequence basis of digital coding through state or the state variation situation of discerning the state that comprises the coloring material elementary cell under the changed condition.
(3) electronic information that obtains basic Serial No. and then obtain imbedding by basic digital this numeral of sequence basis;
The coloring material that state changed under extraneous factor encouraged comprises that temperature change, wet change, ultraviolet light change, infrared light become, smear medicine change coloring material.
The of the same race basic numeral of the diverse location in the basic Serial No. comprises that the different basic numerals of the diverse location in the basic Serial No. comprise the STA representation by identical or different kind of coloring material by the of the same race or STA representation of coloring material of the same race not.
Said state comprises color, and said bearing medium comprises paper, plastics, timber, glass, textile.
Said bearing medium comprises has literal above that, figure, the image bearing medium.
Said literal, figure, image comprise that the elementary cell lap of literal, figure, image and digital coding can not differentiate out; When situation changes and literal, figure, picture overlapping partial data coding coloring material elementary cell part can differentiate out, when said literal, figure, the image situation that is included in changes all or local Transparent color or the identical color that maybe can set off out the coloring material color of presentation code elementary cell of becoming with bearing medium primary colours or surface color.
The shape of said elementary cell comprises expression point, line, figure.
Said coloring material comprises printing ink, ink or ink powder.
Said different directions observation state different dyeing material is included in light change coloring material under the normal optical.
Said different directions observation state different dyeing material comprises that ultraviolet light, infrared light shine the coloring material that following state changes from different directions.
The present invention has following advantage: the problem and the coding that have solved literal, figure, picture overlapping on information buried amount and digital coding and the bearing medium influence problem of appearance.
