Abstract:
The present invention proposes a method for generating a security bi-level image used to form one of the inks of a banknote, said image comprising an original bi-level image and a security pattern, said security pattern being obtained in the spatial domain by the inverse Fourier transform of the combination in the frequency domain between the Fourier transform of an auxiliary image and a two-dimensional sweep, said two-dimensional sweep being a circularly symmetric, two-dimensional pattern created by sweeping a self-similar, one-dimensional function along a 360-degree arc, such as said security pattern being detectable from the maximum value of the cross- correlation of said one-dimensional function with the Fourier transform of one line of said banknote, said method comprising the step of: -determining a distance map of the original bi-level image, -generating a merged image by linearly interpolating at least a part of said distance map with said security pattern, -thresholding the merged image to obtain the security bi-level image, -applying the security bi-level image on a support.
Abstract:
A method for using void pantographs (12) involves generating a test sheet (10) including multiple void pantographs (12, TP), where each of the multiple void pantographs (12, TP) includes a pantograph foreground (14) and a pantograph background (16). The test sheet (10) is printed, and from the printed test sheet (10), at least one of the multiple void pantographs (12, TP) having a covert or semi- covert pantograph foreground (14) and background (16) is identified. The printed test sheet (10) is scanned, and from the scanned test sheet (10), at least one of the multiple void pantographs (12, TP) having an overt pantograph foreground (14) is identified. A workflow is developed for the at least one of the multiple void pantographs (12, TP) having both i) the covert or semi-covert pantograph foreground (14) and background (16) after printing, and ii) the overt pantograph foreground (14) after scanning.
Abstract:
A method for enhancing security printing includes determining fields associated with print job variability. Physical security information is entered, and a physical security data stream is generated from the physical security information. The physical security data stream is mapped to a data stream that is used to provide settings for the fields for the print job variability. The fields for the print job variability are set based upon the mapping the physical security data stream.

A secure media storage device for an imaging device, comprising an interface (40) for receiving digital data, a memory (44) for storing the digital data and for allowing read out of the digital data and a security layer (42) integrated onto the storage device for embedding security data onto the digital data to enable verification of the integrity of the digital data.
Abstract:
A system and method for reliable content access using a cellular/wireless device with imaging capabilities, to use part of a printed or displayed medium for identifying and using a reference to access information, services, or content related to the reference, including capturing an image of the reference with an imaging device, sending the image via a communications network to a processing center, pre-processing to identify relevant frames within the image and to perform general purpose enhancement operations, detecting the most relevant frame within the image, and frame properties, applying geometric, illumination, and focus correction on the relevant frame, using color, aspect ration, and frame color, to perform a coarse recognition and thereby limit the number of possible identifications of a reference within the relevant frame, and using specific techniques of rescaling, histogram equalization, block labeling, edge operation, and normalized cross correlation, to identify the reference within the image.
Abstract:
An image sensing and processing apparatus includes an image sensor that is capable of generating signals carrying data relating to an image sensed by the image sensor. The apparatus includes a microcontroller. The microcontroller includes a wafer substrate. VLIW processor circuitry is positioned on the wafer substrate. Image sensor interface circuitry is positioned on the wafer substrate and is connected between the VLIW processor circuitry and the image sensor. The image sensor interface circuitry is configured to facilitate communication between the VLIW processor circuitry and the image sensor. Bus interface circuitry that is discrete from the image sensor interface circuitry is connected to the VLIW processor circuitry so that the VLIW processor circuitry can communicate with devices other than the image sensor via a bus.
Abstract:
A watermark embedder decomposes a media signal from its perceptual domain to subbands (fig. 2) and embeds a message signal in the edge information of neighboring coefficients of those subbands (fig. 1). A compatible watermark decoder decomposes the watermarked signal into subbands and demodulates the message signal from the edge information of neighboring coefficients.
