A method and apparatus for automatically identifying the contents of an instrument tray by use of a radio-frequency tag (RFID) is disclosed. The method, apparatus, and system enable the instrument tray to receive an interrogation signal from a reader and to respond to the interrogation signal with a code comprised of its identifying information as well as its contents of radio frequency tagged instruments. Both the instrument tray and / or the reader may be coupled by a proximity electromagnetic field, an inductive coupling, or may be units of a wireless LAN system such as a wireless fidelity local area network. The interrogation signal interrogates the tray to ascertain its contents, and the tray in turn transmits a signal to the reader to inform the reader of its contents. The method, apparatus, and system can track, inspect, and verify inbound and outbound surgical instrument trays and kits, to assess, for example, the surgical instruments' and trays' duty life cycle usage.

A biometrics authentication system utilizes information of the palm of the hand of a body to perform individual authentication. A processing unit obtains an image of the palm of the hand of the same body a plurality of times from an image capture unit, judges the degrees of similarity among the characteristic data sets of the plurality of images of the palm of the hand, and registers a plurality of characteristic data sets with a high degree of similarity in a storage unit. And the shape of the hand in the image is checked from the outlines in the image of the palm of the hand, so it is possible to rapidly judge whether image capture has been successful and extract characteristic data, and registration processing can be executed in a short length of time.

Described are a signature verification method, apparatus, and system. The method includes: encrypting a third-party payment identifier and payment information according to a first key to obtain a first signature; encrypting a third-party client identifier and first signature information according to a second key to obtain a second signature; and providing the third-party client identifier, the first signature information, and the second signature to a client server for verification, thereby solving a problem in the background that both a third-party merchant and a payment service party have a key of the third-party merchant used in a payment information transmission process, and once the key is leaked, other people can tamper with or forge order information by using the key, which easily causes property losses to a user or the third-party merchant and has low security, and achieving an effect of improving verification accuracy and improving security of payment information by verifying two signatures.

A speaker verification method is proposed that first builds a general model of user utterances using a set of general training speech data. The user also trains the system by providing a training utterance, such as a passphrase or other spoken utterance. Then in a test phase, the user provides a test utterance which includes some background noise as well as a test voice sample. The background noise is used to bring the condition of the training data closer to that of the test voice sample by modifying the training data and a reduced set of the general data, before creating adapted training and general models. Match scores are generated based on the comparison between the adapted models and the test voice sample, with a final match score calculated based on the difference between the match scores. This final match score gives a measure of the degree of matching between the test voice sample and the training utterance and is based on the degree of matching between the speech characteristics from extracted feature vectors that make up the respective speech signals, and is not a direct comparison of the raw signals themselves. Thus, the method can be used to verify a speaker without necessarily requiring the speaker to provide an identical test phrase to the phrase provided in the training sample.

The invention provides a facial feature verification apparatus capable of synthesizing an image suitable for verification to identify a person subjected to surveillance whom surveillance staff desires to watch. The facial feature verification apparatus includes a plurality of pickup units 1, a pickup controlling unit 2 for controlling the pickup units 1, a displaying unit 3 for displaying images picked up by the pickup units 1, and a verifying unit 4 for detecting a person from the picked up images, extracting a facial image by determining a face area of the person, extracting a facial image from the images picked up by the pickup units 1, synthesizing a plurality of facial features by extracting facial features from the extracted facial images, and verifying the synthesized facial features with the facial features enrolled in advance in a facial image database 5.
