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.
