Patent ID: 7543337

Claim:
System for reading a document comprising a card provided with machine-readable holder details in a machine readable zone and for establishing whether a person presenting the document has a predetermined right, the machine readable zone being provided on the external surface of the card and which document at least contains a chip containing one or more private keys and a biocertificate containing biometric data on the holder as well as data with a predetermined relationship to the machine readable holder details in the machine readable zone which predetermined relationship is based on a one-way function, and wherein the system comprises: a reader for reading the chip and for reading the machine-readable holder details in the machine readable zone; a memory containing details with regard to the predetermined right of the holder; a biometric feature scanner arranged to scan a biometric feature of the holder and to generate scanned biometric data; a processing unit that is connected to the reader, the memory and the biometric feature scanner and is equipped to: establish the authenticity of the chip by transmitting a random challenge code to the chip, receiving a digitally signed random challenge code from the chip that is obtained by digitally signing said random challenge code by said chip using one of said one or more private keys and checking the digitally signed challenge code with a certificate from an issuing authority, establish the authenticity of the data in the biocertificate by receiving digitally signed biocertificate data that is obtained by digitally signing said data in said biocertificate by said chip using one of said one or more private keys and checking the digitally signed biocertificate data with the certificate from said issuing authority, and receive the scanned biometric data on the person presenting the document from the biometric feature scanner and to compare these with the biometric data on the holder from the chip as present in said digitally signed biocertificate data to determine whether the person presenting the document is the holder; receive the machine readable holder details in the machine readable zone as read by the reader from the external surface of the card, check said one-way functional relationship between the machine readable holder details and the data in said chip having said one-way functional relationship to the machine readable holder details in order to authenticate the machine readable holder details in the machine readable zone; read the predetermined right of the holder from the memory; and provide a signal to indicate the predetermined right for the person presenting the document if the chip, the biocertificate data and the machine readable holder details are authentic, the predetermined relationship has been established and the person presenting the document is the same as the holder.
