摘要： The present invention relates to a combined fingerprint sensing and body area network communication system (102, 400) for communication with an electronic unit (302, 312) using the body (301) of a user as communication medium. The system is operable in two states, a fingerprint sensing state, in which a readout circuitry (902) is controlled to provide sensing signals indicative of a fingerprint pattern, and a body area network communication state in which a communication signal is provided to at least a portion of a sensing arrangement(402) by one of the electronic unit and a body area network communication circuitry (404). The communication signal is transmitted using an alternating reference potential of the sensing arrangement. The communication signal being sent from one of the electronic device(100) and the body area network communication circuitry via the user's body and via the sensing arrangement portion to the other one of the electronic unit and the body area network communication circuitry.

摘要： To authenticate a user, fingerprint data for multiple fingers of the user fingers is sensed by a fingerprint sensor (504). Each of these multiple fingers is situated adjacent to at least one other of these multiple fingers while the fingerprint data is being sensed by the fingerprint sensor. Various characteristics of the user's fingers can be analyzed (506) as part of the user authentication, such as the length of the user's fingers relative to one another, the width of the user's fingers relative to one another, the locations of minutiae of one of the user's fingerprints relative to the locations of minutiae of other of the user's fingerprints, and so forth.

摘要： Techniques for generating a gradient characterization for a first fingerprint image are provided. One or more fingerprint feature points are selected from the first fingerprint image. A region is obtained for each of the one or more selected fingerprint feature points. The region is a representation of an area proximate a given fingerprint feature point. Each of the obtained regions is divided into a plurality of sub-regions. A histogram is generated for each of the plurality of sub-regions. For each of the one or more selected fingerprint feature points, the one or more generated histograms are combined into a concatenated histogram. The concatenated histogram is used for identification purposes.

摘要： A method of comparing a first representation of an identifier with a second representation of an identifier, for instance two fingerprints is provided. The method includes selecting a plurality of features in the first representation of an identifier, such as minutia, and linking each feature to one or more of the other features. The information on the features, such as is the minutia type, and on the link or links, such as distance, can then be expressed as a vector. By comparing the vector for the first representation with a vector for the second representation information on the possibilities for them having a common source can be obtained.
