  • Publication number: 20090310779
    Abstract: Data from biometric images such as minutiae of a fingerprint are represented in coordinates x- and y-, and the direction of the ridge flow of the minutia ?; in vector sets of (x1, y1, ?1) are used in generating a 256-bit secret key in a secure manner in enrolling the fingerprint in the Enrolment Phase. The key generation algorithm includes random key generation, threshold signature scheme using polynomial functions, generating random fake minutiae vector sets to form a locked representation of the fingerprint. In the Query Phase, the fingerprint image used to re-generate the secret key is matched against the locked template representation through automatic alignment process using geometric hash table to compare the enrolled minutiae (genuine and fake) with the vector set extracted from the query minutiae sets, and adjustable transform equation is used for adjusting for the minutiae direction, etc.

  • Patent number: 7554703
    Abstract: An optical reading device of a scanning apparatus includes two light sources and a movable lens. The first light source emits a first light when the optical reading device is operated in a flatbed scanning mode. The second light source emits a second light when the optical reading device is operated in a sheetfed scanning mode. The movable mirror is selected to allow for passing the first light without being obstructed by the movable mirror in the flatbed scanning mode or allow for reflecting the second light coming from the second mirror in the sheetfed scanning mode. Due to the special design, the overall volume of the scanning module is reduced.

  • Patent number: 7269206
    Abstract: Within a synchronization stage, m candidates are selected according to secondary correlation results that are generated in a standard code group and slot number identification process. Each candidate contains a respective code group number and slot number, and m is greater than 1. A primary scrambling code correlation process is performed with each candidate to obtain a corresponding primary correlation result for an associated primary scrambling code number. The primary scrambling code correlation process for each candidate is performed over x slots, where x is determined by the ratio f/m, f being the number of slots per frame, and x being less than f. Within integer constraints, x is ideally f/m. The respective code group number, slot number and primary scrambling code number of the candidate having the greatest primary correlation result are then selected as a synchronization result.
