  • Patent number: 7999973
    Abstract: A method of controlling an apparatus which is capable of determining a dot disposition of a copy-forgery-inhibited pattern image is disclosed. The copy-forgery-inhibited pattern image has a latent image area in which a number of first dots and a number of second dots smaller than the first dots are disposed and a background area in which a number of the second dots are disposed. The first dots can be reproduced when copied. The method includes displaying information related to a disposition of the first dots and the second dots in the latent image area, setting a rate of the first dots that are disposed in the latent image area, or a rate of the second dots that are disposed in the latent image area, in accordance with a designation performed by a user, and determining the dot disposition in the latent image area in accordance with the setting of the rate.

  • Patent number: 7995246
    Abstract: The present invention is concerned with detection of a “fragile watermark” in a printed image to aid in a determination whether a document under examination is an original or a copy. The watermark may be applied by phase-space encoding data to be included in the watermark. The image may be examined on a block-by-block basis after scanning. Correlation of detected watermark strength with block brightness and/or with wave vectors used for encoding may be used to detect that the image is a copy.

    Abstract: A method of managing and recovering from the failure of cryptographic devices in a secure transaction processing system including a database, a plurality first cryptographic devices and a standby cryptographic device. Each of the first cryptographic devices periodically generates and sends to the database a total freshness counter record and generates and sends to another of the first cryptographic devices a digital signature and time stamp record. Upon failure of a first cryptographic device, the standby cryptographic device requests and receives the current total freshness counter record and digital signature and time stamp record for the failed first cryptographic device, and uses the digital signature and time stamp record to verify that the total freshness center record is most current. If so verified, the standby cryptographic device assumes the operation of the failed first cryptographic device.

A user establishes various configuration parameters for selected text entities desired to obfuscated. The document is processed and text entities matching the configuration parameters are tagged for obfuscation. The tagged entities are then substituted in the document with obfuscating text. The obfuscating text can be derived from a hash table. The hash table may be used to provide a reverse obfuscation method by which original data can be restored to an obfuscated document.

  • Patent number: 7721099
    Abstract: A printer that prints encrypted information in a document can be the key authority for that document. A document containing encrypted information and a source reference can be printed by a printer associated with a key module. The key module contains the key for decrypting the information. A scanner scanning the document obtains the source reference and the encrypted information. The scanner can use the source reference to send a key request to the printer and the printer can respond with the appropriate key. A decryption module associated with the scanner can use the key to decrypt the information. The decrypted information can be incorporated into a second document that can be electronically stored or printed.

  • Patent number: 7711140
    Abstract: An anti-tampering method for processing documents is disclosed. The method comprises, in regard to an encoding step, the steps of resolving (in a step 2303) in regard to an N-level image to be recorded, a pixel of the image into a major component having N possible values, selecting (in the step 2303) a pattern element depending upon the major component and the position of the pixel in the image, and recording the selected pattern element (in a step 2308) onto a transfer medium. In regard to a corresponding decoding step the method comprises extracting (in a step 2405) from the recorded document, a retrieved pattern element for said pixel, determining a pattern element (in a step 2407) depending upon a major component extracted from the retrieved pattern element and the position of the pixel on the recorded document, and comparing (in a step 2409) the retrieved pattern element and the said determined pattern element.

  • Patent number: 7684064
    Abstract: In order to maintain high security of a job that requires a high security level even after a print interrupt factor has been removed, and to achieve both the effect of maintaining high security of a job that requires a high security level even after the print process is interrupted, and the effect of improving the productivity of jobs other than a job of this type, when a print apparatus which can process a plurality of print jobs including a print job of a first type and that of a second type restarts a print operation of a print job, which is interrupted in the print apparatus, and when the print job is a print of the first type, the print apparatus is controlled to execute an authentication process, and then allowed to restart the print operation of the print job.

  • Publication number: 20100067691
    Abstract: This invention safeguards the integrity of a machine-printed paper document by entangling a characteristic signature derived from the document's paper grain structure with the identities of the printing device and the person or organization which issued the document. This protection is achieved using a certification phase performed by an augmented document printer and an authentication phase performed by an augmented document scanner. In the certification phase, the grain structure of a specific area of the original paper is imaged and processed to generate a unique signature for the paper. This signature is doubly encrypted using the private keys of the augmented printer and the certifier. These encryption steps entangle the signature of the paper with its source information in a way that thwarts counterfeiting attacks which either copy the document or falsely attribute its source to a specific printer and/or certifier.

  • Patent number: 7676038
    Abstract: A method for authenticating a target item with a security code is provided. The method includes the steps of determining a first content of security information to be coded, determining a second content of security information to be coded, printing a plurality of color tiles on a target item where the plurality of color tiles define the first content of security information, and printing one or more micro-markings on one or more of the color tiles located on the target item. The one or more micro-markings define the second content of security information.

    Abstract: A method for secure printing is presented. A document management system (DMS) is provided within a server computer for storing, displaying and printing a plurality of documents. At least a portion of the documents require authentication information for displaying and printing. A web-based capture protection system is provided that prevents proprietary content displayed on a display device from being screen-captured. The web-based capture protection system is combined with the DMS to augment the DMS with capture protection of displayed documents, including intercepting retrieval requests from a client computer to display documents from the DMS.

  • Patent number: 7657031
    Abstract: In a method and system for printing of sensitive data, encrypted sensitive data to be printed is transferred to a printing device having a printing unit. This sensitive data to be printed is decrypted to create decrypted sensitive data. The decrypted sensitive data is converted into control signals for activation of the printing unit. The decrypted sensitive data is stored in a non-volatile memory such that the decrypted sensitive data are distributed in a plurality of memory segments of the non-volatile memory where a relationship of the memory segments is stored as relationship data independently of the stored decrypted sensitive data. The decrypted sensitive data is printed with the printing unit on a recording medium.
