Definitions
- DOVID diffractive optically variable image device
- DOVID One class of DOVID is a hologram where multiple perspective dimensionality is preserved. In layman's nomenclature, the word "hologram" is commonly substituted as a generic term for DOVIDs. Another form of DOVID is grating imagery where only a single perspective dimensionality is preserved. DOVIDs have been in used in many applications to protect replication sensitive documents. Some of the first uses of DOVIDs involved the protection of credit cards. Since then, several types of diffractive imaging technology have been developed to increase the difficulty of producing counterfeit documents. All DOVIDs present a reflected image which changes appearance when tilted slightly at various angles. This unique characteristic makes a DOVID image impossible to copy or imitate by conventional printing and computer based graphical hardware and software processes.
- DOVID technology used to protect replication sensitive documents relies on generic DOVIDs that have no ties to the actual information that is present on the documents.
- DOVID material that is currently in use is becoming increasingly available on the gray market in which the DOVID material is initially legally obtained but later sold or distributed illegally or under questionable circumstances.
- conventional generic DOVIDs are becoming far from secure. What is needed is an enhanced security document, for example an identification document such as a passport, driver's license, credit card, identification card, and the like, that more effectively utilizes DOVID technology, as well as improved methods relating to the production of such documents.
- the invention provides an improved identification document, and improved methods of making an identification document, having enhanced security and replication deterrence, while providing a simple low cost solution to other verification and authentication technologies.
- the invention utilizes a security feature in the form of DOVID technology that, in one embodiment, is integrated with specific data or information on the document to be secured.
- the result is that the security feature is directly tied to data or information that is specific to the document.
- the security feature is verifiable by the human eye so that no high levels of technology are necessary to verify authenticity.
- the security feature has enhanced tamper detection.
- the concepts of the invention could be used on any document in which security (e.g. tamper detection, verification, authentication) of the document is a concern and unauthorized replication of the document is undesirable.
- a document is formed with a multi- layer DOVID that has multiple axes of diffraction.
- the number of DOVID layers can vary depending upon the security requirements, although it is preferred that there be at least two DOVID layers.
- the DOVID can be formed over an image or text that is on the document, with the DOVID formed in precise registration with the image or text.
- the DOVID is specific to, and based on, the image or text that it is formed over.
- an identification document comprises a document surface having information relating to the intended holder of the identification document provided thereon, and a diffractive optically variable image device is on the document surface, where the image device is based on at least a portion of the information on the document surface.
- an identification document comprises a document surface having information relating to the intended holder of the identification document provided thereon, and a multi-layer diffractive optically variable image device on the document surface, where the diffractive optically variable image device has multiple axes of diffraction and is formed on the document surface.
- an identification document comprises a document surface having information provided thereon, and a diffractive optically variable image device on the document surface, where the diffractive optically variable image device is created after the information is formed on the identification document and is based on at least a portion of the information.
- a method of producing an identification document comprises providing an identification document having a document surface with information, including information relating to the intended document holder, formed thereon, and forming a diffractive optically variable image device on the document surface that is at least in part based on at least a portion of the information.
- Figure 1 illustrates a card format suitable for employing the DOVID technology according to the invention.
- Figure 2 is an example of an image that can be printed on a card.
- Figures 3A-C illustrate images of pixel segments that are created from the image in Figure 2.
- Figures 4A-D are images illustrating a bi-level segmentation process.
- Figure 5 illustrates a card with an offset DOVID according to the invention.
- Figure 6 is a flowchart of steps in the method of creating a secure card.
- An identification document capable of utilizing the concepts of the invention is illustrated in Figure 1.
- the document is illustrated as a card 10 which could be, for example, an identification card, a driver's license, a credit card or the like.
- the card 10 has a card surface 12 upon which is located a variety of information, including information relating to the intended holder of the identification document, including one or more of a photographic image 14 and text 16, and information unrelated to the intended holder of the identification document, for example a logo image 18.
- the image 14 is typically of the intended card holder, while the text 16 can include, for example, information on the intended card holder such as the card holder's name and address, information relating to the card issuer such as the employer, or the card number.
- the logo image 18 can be of the type often found on cards, for example a corporate logo, a logo of the entity that issued the card, etc.
- the card 10 can include various combinations of one or more of the image 14, text 16 and logo image 18, as well as other data.
- the card 10 can also include other types of information relating to the intended card holder, either in addition to, or separate from, one or more of the above types of information, for example one or more fingerprints of the card holder and random information that uniquely identifies the card holder.
- the image 14, text 16 and logo image 18 can be printed onto the card surface 12 using suitable card printing technology, such as dye sublimation.
- the image 14 and logo image 18 are often multi-color images that result from Yellow-Magenta- Cyan (YMC) dye sublimation printing, while the text 16 is typically black also resulting from dye sublimation printing.
- Equipment for performing multi-color and monochromatic dye sublimation printing on card surfaces is available from DataCard Corporation of Minnetonka, Minnesota.
- the concepts of the invention will be further described in relation to the image 14 that is YMC printed onto the card surface 12. However, the inventive concepts described herein could also be applied to the text 16 and logo image 18 as well.
- the invention provides a DOVID security feature that is dictated by and unique to the image 14.
- the security feature is formed over the image 14 in registration therewith.
- the DOVID security feature is preferably a multi-layer, multi-axis of diffraction feature that is formed over the image 14.
- Each layer of the DOVID security feature comprises a layer of DOVID material in the form of a diffraction grating printed onto the image 14. The result is that when the image 14 is viewed from different orientations, the image 14 that is seen by the naked eye changes appearance.
- the image 14 over which the DOVID security feature is formed is a white light image defined as an image that is visible in ordinary white light and which does not change color with changes in orientation. Turning now to Figure 2, an example of a dye sublimation printed photographic image 14 is shown.
- the image 14 is actually a YMC, multi-color image, although the various colors are not apparent from Figure 2.
- a segmentation process is performed on the image 14 in Figure 2, in which the image 14 is segmented into a predetermined number of segments based on pixel intensities. Each segment covers a range of pixel intensities. For example, one segment could comprise pixel intensities from 0-84, a second segment could comprise pixel intensities from 85-169, and a third segment could comprise pixel intensities from 170-255.
- the data used to print the image 14 is processed and the data representing the various pixels of the image 14 are placed into the appropriate segment based on the resulting pixel intensity to form separate data sets.
- Segmentation can be performed by a single point process of examining each resulting pixel in a progressive x, y coordinate system, or by the use of a look-up table. For example, if the number of desired segments is three, the data set of segment 1 would contain the data resulting in pixels whose intensities fall within the intensity range assigned to segment 1, for example 0-84. Likewise, the data set of segment 2 would contain the data resulting in pixels whose intensities fall within the intensity range assigned to segment 2, for example 85-169, while the data set of segment 3 would contain the data resulting in pixels whose intensities fall within the intensity range assigned to segment 3, for example 170-255.
- Figures 3 A-C are print-outs of data sets of an exemplary segmentation process on the image in Figure 2.
- Figure 3 A shows a print out 20 of the data set of the lower one-third of the pixel values which can be designated as segment 1.
- Figure 3B shows a print out 22 of the data set of the middle one-third of pixel values which can be designated as segment 2.
- Figure 3C shows a print out 24 of the data set of the upper one-third of pixel values which can be designated as segment 3.
- each DOVID layer is arranged at a different angle from the other DOVID layers.
- a material suitable for use in forming the DOVID grating layers is disclosed in U.S. Patent Application Serial No. 10/605,139, and is produced by ITW Holopak of East Brunswick, New Jersey.
- the image 14 is initially printed onto the card surface 12 at step 30.
- the data used to print the image 14 is processed. Segments having selected ranges of pixel intensity values are chosen at step 34, and the image data is then segmented at step 36 by assigning the pixels that result from the image data to the appropriate segment to create data sets.
- the multi-layer, multi axis DOVID can then be formed over the image.
- the print-out 20/segment 1 in Figure 3 A is used to produce a first DOVID layer with a diffraction grating at a first angle
- print-out 22/segment 2 in Figure 3B is used to produce a second DOVID layer with a diffraction grating at a second angle
- printout 24/segment 3 in Figure 3C is used to produce a third DOVID layer with a diffraction grating at a third angle.
- the data from segment 1 is sent to the printer to print DOVID material as a diffraction grating at a first grating angle onto the image 14 in registration with the image.
- the resulting first DOVID layer replicates the image shown in Figure 3 A.
- the second DOVID layer is formed over the first DOVID layer by sending the data from segment 2 to the printer to print DOVID material as a diffraction grating at a second grating angle onto the first DOVID layer and over the image 14 in registration with the image.
- the resulting second DOVID layer replicates the image shown in Figure 3B.
- the third DOVID layer is formed over the second DOVID layer by sending the data from segment 3 to the printer to print DOVID material as a diffraction grating at a third grating angle onto the second DOVID layer and over the image 14 in registration with the image.
- the resulting third DOVID layer replicates the image shown in Figure 3C.
- the result is a card that has the normal image 14, with the addition of a real time created, three-axis DOVID image that replicates the image 14 and is formed in registration therewith, but with the characteristics of the DOVID.
- Each DOVID layer is formed by a diffraction grating having an axis different than the grating axis of the other DOVID layers so the DOVID layers do not nullify each other.
- the DOVID is not a generic, pre-formed device that is applied to many cards as is conventionally done. Instead, the DOVID is created specifically for each card and is based at least in part on at least a portion of the information on the card.
- the DOVID can thus be referred to as being "card specific” or more generically "document specific”.
- a DOVID that is based on the information on the card surface means that the DOVID is formed by using the printed information or is formed by using the data that is used to produce the printed information.
- the DOVID security technology of the invention could be implemented using two or more DOVID layers. Further, a single layer could be formed over the image 14 if a simple holographic effect is desired. In order to protect the DOVID and the information on the card, a protective overlay can be applied over the card surface 12 after the DOVID is formed.
- segmentation can also be used on a black and white image (or other information on the card) in order to produce a DOVID security feature based on the black and white image.
- All the black pixels are assigned to a second segment that will be used to create the second DOVID layer.
- the pixel information from the edge detection process ( Figure 4A) is assigned to a third segment that will be used to create the third DOVID layer.
- the edge data ( Figure 4A) is subtracted from the black image data resulting in the image information contained in Figure 4B.
- the image data comprising the white threshold data is inverted to make a negative image.
- the edge information ( Figure 4A) is then subtracted from the inverted white image data resulting in the image information contained in Figure 4C.
- the black pixels are assigned a value of one and the white pixels are assigned a value of zero.
- Figure 4A is subtracted from the threshold black image data, any corresponding pixels in that data that are also black in Figure 4A will be turned white (i.e. 1-1). If the corresponding pixels in the image were white, then subtracting the black pixels would result in a negative value (0-1). Only positive value pixels would be printed and represented in the illustrated images as black.
- Figures 4A-C if a pixel is black it will be printed on the document either as part of the white light image or as part of the multiple DOVID layers.
- Figure 4D illustrates the image that would be printed by the K or black panel of the print ribbon and that the images in Figures 4A-C would be formed over. The image constitutes the pixels of the white light image and is created by accepted dithering practices.
- Figures 4A-4C each form one layer of the DOVID, with each layer having a different diffraction grating axis as discussed above.
- the DOVID security features described herein could be produced over any other information on the card 10. Further, the DOVID layers could be offset from the information or a combination of offset and registered.
- Figure 5 illustrates a DOVID 50 that is created as discussed above for Figures 3A-C, but which is offset from the image 14. Additional implementations of the DOVID security technology described herein are illustrated in Figure 1.
- a DOVID that is based at least in part on at least a portion of the text 16 is produced in multiple lines 40 across the surface 12 of the card 10.
- each line 40 extends substantially the entire length of the card, and the lines are spaced from one another along substantially the entire height of the card, although other configurations are possible.
- the text upon which the DOVID is based could be, for example, the card holders name.
- the card holders entire name could be reproduced as a DOVID, in which the name repeats in each line 40, and forms the background to the card.
- a DOVID that is based at least in part on at least a portion of the logo image 18 is produced in multiple lines 42 across the surface 12 of the card 10.
- each line 42 extends substantially the entire length of the card, and the lines are spaced from one another along substantially the entire height of the card, although other configurations are possible.
- the entire logo image could be reproduced as a DOVID, in which the DOVID logo repeats in each line 42, and forms the background to the card.
- the technology and concepts described herein can be further enhanced by utilizing microprinting on the last (or uppermost) layer of the DOVID.
