Checking of right to access

Abstract

A system for checking the right to access to sensitive information is described, said checking being based on current biometric data of a person whose right to access to the sensitive information is to be checked. The system comprises a data carrier (1) and a processing unit (2). The data carrier (1) comprises a memory (6) containing sensitive information, a signal processing means (5) and a communication means (3). The processing unit (2) is adapted to receive the current biometric data from the person and comprises a memory (10), a signal processing means (7) and a communication means (4). The processor (7) of the processing unit (2) preprocesses the current biometric data and transfers the same to the processor (5) of the data carrier (1) via the communication means (3, 4). The procesor (5) of the data carrier (1) compares the received preprocessed biometric data with biometric reference data stored in advance in the memory (6) of the data carrier (1) to determine whether the right to access to the sensitive information exists. A data carrier (1), a processing unit (2) and a method of checking, based on current biometric data of a person, the right to access to sensitive information stored on a data carrier (1) are also described.

Description

technical field [0001] The invention relates to a system for checking the right to access sensitive information based on biometric data of the type stated in the preamble of claim 1 attached hereto. The invention also relates to a data carrier, a processing unit and a method of checking, based on biometric data, the right to access sensitive information stored on the data carrier. Background technique [0002] In many cases access to information, access to rooms, etc. must be restricted to certain individuals. For example, there are situations where electronic money transactions take place over the Internet, in hospitals where access to medical records must be restricted, or in workplaces where only certain individuals are allowed to access certain information or enter certain rooms. [0003] For this purpose, something called a smart card is often used. A smart card can be described as a credit card-sized card with an internal processor or signal processing device, memory...

Problems solved by technology

[0011] Although this solution removes the use of the PIN code and keeps the template always on the smart card, it still leaves certain disadvantages

For example, smart cards are relatively expensive and difficult to make acceptable to a large number of users, because smart cards contain a large number of components and must be specially customized

Increased probability of smart card outages due to the large number of components and all operations affecting the smart card
