Embodiment
The invention provides system and method, be used for other object of authentication document, commodity and the decodable coded image of use optics.Method of the present invention provides the digitally captured coded image that is applied to want authentication object.This can use scanner or other imaging device to produce the digital picture of being caught and realize.Then, be equipped with the data processor of digital decoder can be used to discern and decode, and from decoded result, extract mark and/or information from the coded image of the digital picture of being caught.Then, the mark of extraction and/or the information object or the file of coded image that can be used for authentication application.In certain embodiments, decoded picture does not need to be seen.In certain embodiments, can catch decoded picture by site inspection person, the inspector is transferred to the processor (or a series of processor) of separation with the image of catching, and image is decoded, and compare with desired image alternatively.Then, the result can be turned back to site inspection person or other authorized person.By other embodiment of following description and variation is conspicuous.
As previously mentioned, authentication method of the present invention typically uses and is embedded in background or source images and prints on coded image on the project that may be distorted, forge and copy.Just as used herein, term " coded image " is meant in background or the processed and/or hiding image of mode to use or to print in other image, and under the situation of not using decoding device, human eye can not the recognition coding image.Some coded images are hidden, and therefore are difficult to from background or main image it be identified.Other coded image can see at an easy rate that but not readable, this is by systemic scrambling or processing because of picture material.
The coded image that has meaning for the present invention is to be configured to use the image that carries out optical decoder based on the decoding device of lens.This imagery exploitation the advantage of particular type lens (for example biconvex lens), thereby come the sampled images content based on optical characteristics.For example, biconvex lens can be used for sampling and the enlarged image content based on lenticular layer (lenticule) frequency of lens.Typically, use a kind of employed image of encoding in the several different methods, described method relates to sets up the regular periods pattern that has with the corresponding frequency of biconvex lens that is used as decoder, and the corresponding distortion pattern of the content of introducing and coded image.These distortions can be very little, thereby be difficult to maybe to utilize bore hole to distinguish image from mode of rule.Can use specific photographic equipment to produce such coded image, as U.S. Patent No. 3,937 with analog form, 565 is disclosed, or produce coded image with digital form, as United States Patent (USP) 5,708,717 (' 717 patents) are disclosed, and the two in the lump at this as a reference.
Digitally coded image can be embedded in background or other image, thereby is difficult to only identify the existence of coded image.With reference to figure 1, can use main image or source images 20 and less important image 40 to form coded image 10, wherein watching the mode of less important image 40 that less important image 40 is embedded in the main image 20 by the decoding device 3030 of preset frequency.Identical with the coded image 10 of Fig. 1, main image can be greyish white or the color background image, maybe can comprise the visual image content, as pattern or photo or other mark pattern.Less important image can also be arbitrary form image or mark, and can comprise relevant with main image in some way mark.In example codes image 10, less important image 40 is based on the repeat pattern of vocabulary " Department ofTransportation ".Less important image can be encoded separately, merge then or be embedded in the main image, maybe can utilize and embed identical mode and come the coded auxiliary image, thereby realize telescopiny.As shown in Figure 1, can watch less important image by on coded image 10, decoding device 30 being set with correct direction.In the example of Fig. 1, decoding device has trunnion axis 32 and vertical axis 34, and coded image 10 has trunnion axis 22 and vertical axis 24.When the trunnion axis 32 of decoding device 30 during, can leak less important image with respect to 22 one-tenth α decodings of trunnion axis angular orientation of coded image 10.Decoding angle α is coding and embeds the coding parameter that produces before the less important image.
Embed less important image or can be divided into two kinds of universal methods with the method for main image co-registration.In first method, utilize preset frequency that the cyclic behaviour of rule is forced on the main image.This is mainly by realizing with the main image of preset frequency rasterisation.Then, less important image mapped is arrived main image, thereby can change the regular behavior of main image with comprising the corresponding position of less important image of picture material.These changes are very little, to such an extent as to be difficult to be discovered by human eye.Yet, when the biconvex lens that has with the corresponding frequency of preset frequency is set, thereby can change the mode that forms the less important image of the hiding main picture material of sampling to identify on main image.
In the second approach, at first the cyclic behaviour of rule is forced at less important image rather than main image, as long as wherein exist the content of less important image the change of this behavior just to occur.Then, less important image mapped is come to change by pixel ground the content of main image to main image based on the content of coded auxiliary image.
The another kind of method of embedded images is generally used for bank note and check.In this method, by generating hidden image in the direction that changes raster element in the visual image with the corresponding position of the content of hidden image.For example, the vertical light grid line of main image can become horizontal line with the corresponding position of hidden image.Typically can see hidden image by the bank note that tilts slightly.Yet, also by decode deviation in the main image of optical decoder device.This is because the grid stroke of main image is being hidden on the location of content and will extended along the length of the biconvex lens line of decoder, and exists on the position that hides content and have only a cross section (crosssection).This species diversity causes that hidden image seems brighter than viewable portion when watching by decoder.
All above-mentioned image encode methods and coded image result's thereof public thinking is that it relates to the deviation (for example, locus, tonal density, grating angle) from the cyclic behaviour of rule.Can gather to come the cyclic behaviour of formation rule and the deviation that Yin Qi produces based on employed coding method and predetermined coding parameter.Can make deviation apparent by the decoder that use has with one or more coding parameter corresponding characteristic.For example, wherein one of coding parameter can be the frequency of the cyclic behaviour of rule.Decoder (based on hardware or based on software) must dispose according to this frequency.For example, under the situation of biconvex lens, produce the lens frequency, so that frequency or the even-multiple of lens frequency identical of the cyclic behaviour of rule with the lens frequency.Then, biconvex lens can serve as content sampling device/amplifier, emphasizes the deviation from the cyclic behaviour of rule, and it is assembled in the less important image.
Biconvex lens can be used for decode content by the visual coded images of systemic scrambling and the coded image that is embedded in main image or background.Yet,, 350 (' 350 application as U.S. Patent application No.11/068) and described, also can be used to the coded image of decoding and digitally having produced or having caught based on the decoder of software.These decoders can be suitable for decoding Any Digit version of optical encoding image comprises also unprinted digital coding image and has scanned or be converted to by other means the printed encoded image of digital form.Digital coding image can be the hidden image that is embedded in background or the main image, maybe can be the visual image of systematicness adding or processing.Main image can be the blank image (for example grey frame) that does not have to discern content, maybe can be to have the real image that can discern content.
Be used for that digitally the software of decode encoded images in fact can be in conjunction with any data processor.For the purpose that realizes authentication method of the present invention, software can use any coding/decoding method, including, but not limited in the method described in the application of ' 350.It comprises the information of the main image of method (1) needs, less important image or both contents; Method (2) need be about any knowledge of picture material.Two kinds of Method types all need to be used to encode and embed the coding parameter of less important image.
As described in ' 350 applications, can use image acquisition equipment to scan or digitally catch printed encoded image.Term " image acquisition equipment " is meant and is used to catch or the establishing any being equipped with or system of the digital picture of spanned file or object or its target part as used herein.Image acquisition equipment including, but not limited to scanner, digital camera, have the system of the combination of analog video camera and frame grabber.Image acquisition equipment can be suitable for using visible light and invisible light (as UV and the IR) part in the electromagnetic spectrum to catch image.
Can handle the coded image (that is, having scanned or used the digitally captured printed encoded image of image acquisition equipment) of being caught by being suitable for using the processor that one or more decoding algorithms based on software produce decoded result.Method use such as the optical character identification (OCR), decoding processor can also be suitable for extracting mark and/or the information in the decoded picture, and the mark that extracted and/or information and predetermined authentication criterion are compared.As described below, decoding processor can be positioned at the position away from image acquisition equipment.
With reference now to Fig. 2,, the coded image that Basic Authentication method M100 according to the present invention can digitally decode and be caught.Method M100 can be used for the checkout object to determine whether to have used to this tested object the coded image of expectation, and the coded image of expectation has been applied to all authentication objects.Be typically referred to as by mandate source or authorization at this employed term " authentication " and produce object.The coded image of expectation is the version of code of predetermined authentication image.The coded image of expectation can be identical for each tested object, or for the different code-change image of each object.Can suppose not carry any object of expecting coded image and indicate non-authentication property, or indicate applied object or mark also not to change.
