    摘要: A method and apparatus for collecting and securely transmitting biometric data over a network contains a sensor, preferably a camera, for collecting biometric data and code generating hardware and software. The camera data is digitized and a unique code which is a function of the digitized camera data, a secret key and a transaction token is attached to the digital file. The code may identify the sensor which acquired the biometric information, a time at which the biometric information was acquired, or a time interval during which the data is considered to be valid, and a unique transaction code. The data and code are transmitted over a network to a server which authenticates that the data has not been altered by recomputing the code using its own knowledge of the secret key and transaction token needed to generate the code. If the data is authentic the server then computes a biometric template using the data. This biometric template is then compared to a previously defined biometric template to identify the user and give the user access to a secured resource. The system can be used for online banking and Internet commerce transactions.

    摘要: Disclosed are techniques for transforming a biometric template so that each application uses a unique template format. One transformed template cannot be successfully matched to a second template extracted from the same biologic entity unless the second template is transformed so that its format is identical to that of the first template. Thus a template generated in a format corresponding to application A could not be used to authenticate a user for application B because the enrollment database for application B would have a different format than the enrollment database for application A.

    摘要: A method and apparatus are disclosed whereby a person signs an electronic document using a personal biometric. A sample of biometric data is collected from the person at the time of the signing of the document, and encrypted with the document itself and various other data to form a digital signature. The encryption technique utilized irrefutably couples the biometric data with the document. To authenticate the coupling, an authenticator signature is generated using the original data and is then compared with the original signature to verify a match there between. The biometric data used to generate the authenticator signature is then matched with a sample provided by an alleged signer of the document to verify his or her identity.
