Abstract:
A system for checking the right to access to information, the checking being based on current fingerprint data of a person whose right to access to the information is to be checked, the system comprisinga portable data carrier comprising a signal processing means for processing signals, a communication means for performing communications and a memory containing the information, feature reference data of a fingerprint of a person who has the right to access to the information and fingerprint reference data in the form of a digital representation of at least a partial area of the fingerprint of the person who has the right to access to the information, and a processing unit, which is adapted to receive the current fingerprint data from the person whose right to access to the information is to be checked, comprising a memory, a signal processing means for processing signals and a communication means for communicating, wherein the signal processing means of the processing unit is adapted to pre-process the current fingerprint data, the pre-processing comprising extracting features from the current fingerprint data and comparing them with the feature reference data which has been transferred from the data carrier to the processing unit, and to transfer the pre-processed current fingerprint data to the signal processing means of the data carrier via the communication means of both the data carrier and the processing unit, and wherein the signal processing means of the data carrier is adapted to compare the received pre-processed fingerprint data with the fingerprint reference data stored in advance in the memory of the data carrier to determine whether the right to access to the sensitive information exists.
