A fingerprint sensor device with built-in liveness detection capabilities includes: an area sensor disposed on a top surface of a substrate; a stiffener disposed below a bottom surface of the substrate; a printed circuit making electrical connection to the sensor disposed below the stiffener; and a light source and a photodetector. At least one of the light source and photodetector is disposed on the printed circuit below the area sensor. The stiffener includes at least one through-hole located with respect to the light source or photodetector to allow light from the light source to transmit through the stiffener towards a finger located on the area sensor or to allow light reflected from the finger to pass through the stiffener to the photodetector.

Fingerprint sensor with liveness detection

The invention relates to a process for releasing the access to a computer system or to a program for a user via a terminal () without software having to be installed solely for this purpose on the terminal (). A data connection is established between a portable data carrier () of the user and the terminal (). An authentication of the user is performed by the portable data carrier (). If the authentication is successful, an access code is made available by the portable data carrier () for releasing the access to the computer system or to the program for a transmission via the data connection.

Process for releasing the access to a computer system or to a program

A portable device for activating access in or over a computer network that is connectable to a terminal, which is connected to the computer network at least temporarily. The portable device is configured to be insertable into a communication path between the terminal and the computer network, for authenticating a user, and for providing access data for activating access.

Portable device for clearing access

The present invention relates to devices and a method for biometric authentication by means of reference data stored in a memory of a portable data carrier. For biometric authentication methods to make their final breakthrough with respect to more widespread use, there is a need for standardized generation of reference data for the particular biometric features used for authentication. Different suppliers of methods and devices for biometric authentication have hitherto used algorithms for generating the reference data which normally lead to different reference data which are not interchangeable. This limits the employability of biometric methods to the supplier's particular system. The present invention avoids this problem by storing several sets of biometric reference data, thereby increasing the likelihood of the evaluation of at least one set of stored biometric reference data being possible. Thus, the desired system-independent authentication can be attained.

Devices and methods for biometric authentication

A data carrier has stored thereon a secret code and a user's biometric data. In using the data carrier, a data carrier terminal is first authenticated for access to data stored in the data carrier by reading a secret code from the data carrier in a manner known only to an authorized terminal, and then displaying the read secret on the data carrier terminal. If the user determines that the displayed secret code is correct, the user then presents a biometric feature which is read and compared to the biometric data stored on the data carrier. If the read biometric data matches the stored biometric data, then the user is authorized for further use of the data carrier on the data carrier terminal.

Method, data carrier and system for authentication of a user and a terminal

A method, apparatus and system for biometric authentication of a person are proposed. Since the detection of biometric data never matches 100 percent, authentication is already effected when the detected data exceed a defined threshold value in comparison to stored reference data. In order to increase security, the invention provides that information about the person's individual properties influencing the biometric data is stored and taken into account in the authentication process. For example, the threshold value is set low upon comparison of a fingerprint only if the person has exceptionally dry or moist skin. On the other hand, the sensor for detecting the biometric data of the fingerprint can also be set to be more sensitive or less sensitive depending on the stored information.
