Embodiment Construction

[0031] Figure 1 shows a basic prior art system for identifying and authenticating an individual based on biological data associated with the individual. The individual's raw biometric data, such as fingerprints, iris or retina, face or hand geometry, voice characteristics, etc., are obtained on the sensor 101 . The acquired data is typically processed on a processing device 102, such as a digital signal processor (DSP). This data is then stored in the service provider's database 103, preferably in encrypted form. This is a one-time initialization process for an individual wishing to access a particular system in order to register that individual. Encryption is performed to protect the identity of the individual, i.e. the individual's biological data. Then when the individual wants to access this service, she will provide the biometric data to the sensor 102 . The data is then processed and compared with the individual's pre-stored biological data in a database. If there is...

Abstract

The present invention relates to a method of authenticating an individual (321) at an authenticating device (311) and an authenticating system for authenticating an individual. A basic idea of the present invention is to store, at a device or a system with which an individual wishes to authenticate herself, one or more data structures each comprising a value based on an identifier pertaining to the individual and an encrypted copy of the identifier. When the individual wants to authenticate herself, she contacts the authenticating device whereby a request is made to attain the encrypted identifier included in a specific data structure stored at the authenticating device. The individual subsequently provides proof to the authenticating device that she actually knows the identifier.

Description

technical field [0001] The invention relates to a method of authenticating an individual on an authentication device and an authentication system for authenticating an individual. Background technique [0002] Verification of physical objects may have many applications, such as conditional access to secure buildings or conditional access to digital data (e.g. stored on computers or removable storage media), or for identification purposes (e.g. for a particular activity to identify person charges). [0003] Biometrics for identification and / or authentication are increasingly recognized as a better alternative to traditional means of identification such as passwords and pin codes. The number of systems requiring authentication in the form of passwords / pins is steadily increasing, and thus the number of passwords / pins users must remember. And further, due to the difficulty of remembering passwords / pin codes, users must also write them down, which is easy to steal. Some solut...
