摘要:
A biometric authentication system including a server device for storing biometric data of a plurality of users into a registration unit and a client device for collecting the biometric data from the users. The client device comprises aholdingunit for holding biometric data which is collected by the client device and authenticated by the server device, as cached biometric data, together with user information, a client verification unit for verifying the biometric data collected from the user against the cached biometric data at the authentication, a synthesizing unit for acquiring synthesis information of the cached biometric data and the biometric data collected from the user which are successfully verified, and a transmission unit for transmitting the user information of the biometric data which is successfully verified and the synthesis information to the server device. The server device comprises a server verification unit for verifying one of a plurality of biometric data registered in the registration unit, which is specified by the user information transmitted from the client device, against the synthesis information transmitted from the client device.

To provide cancelable biometrics, random projection transforms are used to produce transformed biometric data that may be used for authentication purposes. Each random projection transform provides a one-way or irreversible transformation such that the resulting transformed biometric data alone cannot be used to reconstruct the biometric data. Enrollment and backup transforms are produced based on enrollment biometric data. Authentication is possible by similarly transforming authentication biometric and then securely reconstructing the enrollment and authentication biometric data for comparison. In a similar manner, the enrollment and backup transforms may be used to reenroll biometric data when its corresponding transformed biometric data is compromised without requiring further user intervention.

The present invention relates to a system for distributed secure storage of personal, in particular biometric, data. The invention also relates to a secure identity-monitoring system and to a local monitoring device. The invention finally relates to a secure identity-monitoring method. The personal data, in particular biometric impressions, for the persons are pre-stored in a central base, and the monitoring procedure comprises: a preliminary step of forming a base of derived data obtained from source personal data by means of a derivation function; a step (31) of acquiring data from the person; a step (32) of applying the derivation function to said acquired data; and a step (33) of comparing the result of the derivation function with the set of data derived from the base. The invention is of use in, for example, decentralized systems for biometric verification while ensuring the confidentiality of the personal data.

A vehicle handle apparatus is provided with: a handle base fixed to a door of a vehicle; an operation handle rotatably connected to the handle base; and a relay lever which is rotatably connected to the handle base, and which is driven to rotate around a pivot by operating the operation handle. The relay lever is provided with: a sub-lever member including a connecting portion connected to an operating force transmitting member coupled to a door lock device in the door; and a main lever member which is driven to rotate by operating the operation handle. The sub-lever member and the main lever member are pivotally supported around the pivot so as to relatively rotate with respect to each other. The main lever member is connected with the sub-lever member by a connecting element when the connecting element is in a connecting position. The connecting element is withdrawn from said connecting position by inputting a predetermined acceleration, so that a connection of the main lever member with the sub-lever member is released.

A method of confirming the identity of a user includes processing biometric credentials, generating a user configurablc policy (88) including a plurality of authenticating entities (90), storing the user configurable policy (88) in a device (54), presenting (100) the device (54) to an authenticating entity (90) at an authentication station, and requesting (104) biometric (76) and personal data (78) of the user from the device data. The biometric data (76) corresponds to at least one biometric feature desired for authenticating the user and the requesting operation (104) is performed by a workstation (48) of the authenticating entity (90). Moreover, the method includes consulting the user configurable policy (88) in response to the requesting operation (104) to determine whether the requested biometric data (76) is permitted to be released from the device data, and releasing (108) the requested biometric (76) and personal data (78) from the device data to the one authenticating entity (90) when the default rule (94) associated with the one authenticating entity (90) permits releasing the requested biometric (76) and personal data (78).

A security system includes a terminal system and a smart card. The terminal system generates relative fingerprint information of a user from absolute fingerprint information of the user, determines a similarity between the generated relative feature information of the user and registered relative fingerprint information of a smart card owner transmitted from the smart card to generate variation information, and applies the variation information to the user absolute fingerprint information to generate modified user absolute fingerprint information. The smart card determines the similarity between the modified user absolute feature information and registered absolute feature information of the smart card owner to perform a certification operation.
摘要:
Upon registration, a client extracts plural feature points and information (identification information) by which each of the feature points can be identified, from a user's fingerprint, and randomly generates a transformation parameter for each feature point to transform the coordinates and direction. The transformed identification information (template) is transmitted to an authentication server and stored in a,memory. The identification information and transformation parameters of the feature points are stored in a memory medium of the user. Upon authentication of the user, the client extracts feature points from the user' s fingerprint, and identifies the feature points by the identification information in the memory medium. The client transforms the identified feature points by reading the corresponding transformation parameters from the memory medium, and transmits the transformed information to the authentication server. The server verifies the received identification information against the template registered in advance, to authenticate the user.
