  • Patent number: 7366301
    Abstract: A multiple-layered watermark is generated to be placed on document, to protect against counterfeiting and forgery. Hidden information embedded into each of the watermark's layers is only detectable by using a corresponding decoder. Because of the multiple-layered structure, it is difficult to reverse engineer the optical watermark. The generalized watermark structure significantly increases the “key space” of the decoder.

  • Patent number: 7315621
    Abstract: A characteristic amount is retained and calculated from an entered video signal. Embedment intensity is retained and calculated from the retained characteristic amount. Embedment information is embedded as digital watermarks into the entered video signal in accordance with the retained embedment intensity of the previous frame or field that is located at a position earlier in time than a target image subject to digital watermark embedment. As a result, an output signal of video having the digital watermarks embedded therein is produced. The digital watermarks are embedded into the target image with reference to another image located at a position earlier in time than the target image. Such digital watermark embedment suppresses a delay in output of an output image with reference to an input image.

  • Patent number: 7227972
    Abstract: The disclosure describes a method of progressively decoding a digital watermark on a distributed computing platform. A client device equipped with a digital camera, such as a PDA or cell phone, captures a digital image of a watermarked object, and pre-filters the image to isolate a portion of the image data suspected of containing a digital watermark. The pre-filter de-correlates a portion of the image data suspected of containing a digital watermark from the remaining host image signal using a predictive filter. The client then quantizes the filtered data and progressively transmits the quantized data to a watermark decoder. The progressive transmitter sends image data as necessary to achieve a valid decoding operation. To reduce bandwidth requirements, the transmitter starts with the most highly quantized version of the filtered image, and sends lesser quantized versions until the watermark decoder completes a successful decoding operation.

  • Patent number: 7203666
    Abstract: A virtual postage metering system and method provides value added services corresponding to postage metering transactions. Funds are not stored at a user's site, reducing the risk of unauthorized modification of accounting balances. There is a database record of every mailpiece, thereby improving verification since all valid pieces are known. Furthermore, the present invention enables the Post to know the volume of mail to be processed prior to receipt of physical mail pieces. Since more mailer data is available (e.g. when users usually mail, how much mail per day, average postage amount) the virtual postage metering system enables the postal service to predict mail handling patterns. Additionally, users have the option to pay as they go which contrasts present systems in which funds must be on deposit prior to being downloaded to a meter although such downloaded funds may remain in the meter for weeks before being used.

  • Patent number: 7058199
    Abstract: We propose methods for generating a halftone image, in which each pixel takes one of two tone values. The generated image contains hidden data, which is present at data storage pixels chosen using a pseudo-random number generator. In a first case, the data is hidden within an existing halftone image by reversing the tone value at certain of the data storage pixels, and at pixels neighboring the data storage pixels. In a second case, the halftone image is generated from a grey-scale image, and data is hidden during this conversion process.

  • Patent number: 7036016
    Abstract: A method for securing passwords, personal identification numbers and identifying patterns utilizes a MasterCode camouflaged within a grid which contains all the characters, symbols or pictograms of which the MasterCode is a subset. For securing numeric sequences, the MasterCode is comprised of ten characters randomly associated to a corresponding digit (including zero). The characters thereby associated with each numeric password are expanded into an ordinary, natural language word, a SecureWord using non-associated letters. The MasterCode is masked by its unique placement in a MasterGrid known only to the user. For securing passwords comprised of alpha numeric symbolic characters, each unique character, the MasterCode, is assigned a sequential number which becomes a sequence of positions in the MasterGrid with each MasterCode character placed in the appropriate position and the remainder of the character set filled in. SecureNumbers are the positions in the MasterGrid of each character in a password.

  • Patent number: 7003501
    Abstract: A method and a system for enabling secure authentication of a user in a computerized card access transaction. A card, identified by an identification number is issued to the user, containing software for generating a surrogate number referred to as a Cybercoupon for use in place of the regular card number. Online intrusion is avoided and the system is rendered portable for use on any computer equipped with a compatible operating system, by avoiding storage of any part of the system on the user's computer, placing the entire system instead on the card itself. The card contains advertising which appears on the user's computer screen. The card is protected by a password. If an incorrect password is entered more than a preset number of times, an “alert” Cybercoupon is generated containing a code advising the card issuer that an irregular attempt has been made to access the card.
