摘要： Disclosed is a low-cost fingerprint capture device that can be integrated in a computer mouse. Fingerprint information captured with such a device is transmitted to a computer via a serial port. As such ports are relatively slow, the capture device provides a low resolution fingerprint image (having less than 512 x 512 pixels). This low resolution data is processed by an iterative method that contrasts sectors of the image in a direction specified by 'flow vectors'. These flow vectors specify an average direction of fingerprint ridgelines in the sector under consideration. These methodologies enable the transmission of fingerprint data over the relatively slow RS232 serial protocol, in a manner that allows virtually instantaneous fingerprint identification.

摘要： Disclosed are a system and a method employing a user's fingerprint to authenticate a wireless communication. The user's personal fingerprint is employed as the secret key in the context of a modified "challenge-response" scenario. The system includes a fingerprint capture module on a mobile personal wireless communication device (e.g., a wireless telephone) and a central authentication system coupled to a conventional mobile switching center. The central authentication system contains information that associates each mobile identification number ("MIN") with a particular user's fingerprint. When a wireless communication is to be initiated, the central authentication system engages in a challenge-response authentication with the mobile switching station or the wireless phone using the stored fingerprint associated with the MIN through the common air interface. The correct response from the mobile station will only be generated when the user's fingerprint entered through the fingerprint capture module attached to the mobile station matches the information sent from the central authentication system, and only calls placed from authorized users are connected.

摘要： A method is provided for protecting distributed software, either through the internet/telephone networks or via physical storage media like floppy diskettes, magnetic tapes, CD-ROMS, DVD-ROMS, etc., by using biometric information (personal fingerprint information in particular). In one approach, the fingerprint of the software purchaser is embedded into the purchased software at the time of purchase. All subsequent use of the software by the purchaser at his/her home or office is subject to (a) providing his/her fingerprint again and (b) the fingerprint matches that embedded in the purchased software. In another related approach, prior to the use or installation of distributed software, the user's computer calls a central management server station. The software then requests the user to provide his or her fingerprint by any device that would capture such information. The fingerprint information is then processed on the local user computer by any image processing program, and the relevant information is then sent to the central server along with a key or serial number that is built into the distributed software. The central management server then compares the provided information with the information previously stored in its central database and decides whether the user is authorized. Such a method can also be employed in a licence management system whereby software product usage can be remotely monitored and fees for usage charged appropriately.

摘要： A method for modelling the electron density distribution of a macromolecule in a defined asymmetric unit of a crystal lattice having locations of uniformly diffracting electron density includes the steps of: producing an initial distribution (42) of scattering bodies with a asymmetric unit having the same dimensions as the defined asymmetric unit; calculating scattering amplitudes (37) of the initial distribution and determining the correlation (37) between the calculated scattering amplitudes and the normalized amplitudes; moving at least one of the scattering bodies (36) within the asymmetric unit to create a modified distribution; calculating scattering amplitudes and phases of the modified distribution and determining the correlation between the calculated amplitudes and producing a final distribution of scattering bodies by repeating moving and calculating steps until the correlation between the calculated scattering amplitudes and the normalized amplitudes is effectively maximized, the final distribution of scattering bodies defining the electron density of the crystal (38).
