  • Patent number: 7433499
    Abstract: This present invention includes a method for capturing and transmitting data captured from a writing instrument in a secure manner. More specifically, the biometric information collected from the pen is coupled with at least one additional data point for encryption. The user initially uses the pen to create a signature which is converted into an encrypted reference value in accordance with the present invention. When authentication is desired, the user uses the same or similar pen to create a signature which again is converted into an encrypted data value. Thereafter, the encrypted reference value is compared to the encrypted data value to determine if the values substantially match. There is not need to retain the original reference signature, thereby enhancing the security of the overall system.

  • Patent number: 7413114
    Abstract: In the method of handling mail items, while a mail item is on its first pass through the machine, the method consists in forming a digital image of the surface of the mail item, in deriving, from the image, a digital fingerprint characterizing the mail item, and in recording said digital fingerprint in a memory in correspondence with the bar code printed on the mail item. While the mail item is on its second pass through the machine, the method consists in reading the printed bar code that is printed on the mail item, and, if it has not been possible to extract completely the information contained in the printed code read off the mail item, in using said correspondence in the memory between the printed code that is printed on the mail item and the digital fingerprint that characterizes the mail item to continue machine-sorting the mail item, thereby contributing to reducing the error rate.

    Abstract: A signature authentication device is disclosed. Even when there are variations in an input hand-written signature during the registration of the signature or during the authentication of the signature, the signature authentication device easily registers or authenticates the signature. The signature authentication device allows a user to re-register the signature without a risk that sensitive information stored in a computer is monitored by someone else. A plurality of pieces of authentication signature data for a single user is stored. If comparison for authentication between input signature data and at least a single piece of the plurality of the pieces of the authentication signature data is successful, then the authentication is regarded as successful. During signature registration, the plurality of the pieces of the authentication signature data is stored in a storage unit.

  • Publication number: 20080175445
    Abstract: Apparatus and methods are disclosed for verifying identity using a plurality of biometric samples collected during a pre-enrollment phase, where the plurality of biometric samples concern one or more biometric measures. In one embodiment, the biometric measure comprises an individual's signature, samples of which are collected over a period of time prior to an enrollment procedure. Collecting signatures over a period of time prior to an enrollment procedure allows a more robust signature model to be developed since the signature model will reflect natural, statistically significant, variations that occur over time. During an enrollment procedure, the user then attests to the validity of the signatures collected during the pre-enrollment phase. Valid signatures are used to construct a signature model that will be used to authenticate signatures provided during later transactions.

    Abstract: A method and system for the automatic identification of audio, video, multimedia, and/or data recordings based on immutable characteristics of these works. The invention does not require the insertion of identifying codes or signals into the recording. This allows the system to be used to identify existing recordings that have not been through a coding process at the time that they were generated. Instead, each work to be recognized is “played” into the system where it is subjected to an automatic signal analysis process that locates salient features and computes a statistical representation of these properties. These features are then stored as patterns for later recognition of live input signal streams. A different set of features is derived for each audio or video work to be identified and stored. During real-time monitoring of a signal stream, a similar automatic signal analysis process is carried out, and many features are computed for comparison with the patterns stored in a large feature database.

  • Patent number: 7068821
    Abstract: An input coordinate sequence is acquired by sampling a handwritten input pattern at predetermined intervals, and a pattern expressed by this input coordinate sequence is approximated by coupling a plurality of line segments to attain line segment conversion. Adjacent angle data ?[i] is generated based on the directions of the respective line segments. At this time, the segment line length along line segments of all the line segments is divided by a predetermined value at equal intervals, and the angles obtained from the directions of the line segments at respective division positions are defined as ?[i]. This ?[i] is compared with a standard pattern (adjacent angle distribution data) prepared in advance to obtain a matching level. In this way, more accurate pattern matching for a handwritten input, which is approximately invariant to affine transformation and can reduce the influence of discretization errors can be implemented.

  • Patent number: 6973204
    Abstract: It is controlled by a non-transformation coefficient calculated by a non-transformation calculation section, whether feedback is performed or not. When the feedback is ended, a collation value calculation section calculates a collation value (coincidence coefficient×non-transformation coefficient). A display process section compares the collation value with a predetermined threshold value. When the collation value is a threshold value or more, a signature is decided as a true signature, and the transformation-corrected image and the reference image are displayed such that these images overlap.
