Electronic data storage medium with fingerprint verification capability
First Claim
1. An electronic data storage medium adapted to be accessed by a data terminal, said electronic data storage medium comprising:
- a non-volatile memory device for storing a data file and fingerprint reference data obtained by scanning a fingerprint of a person authorized to access the data file;
a fingerprint sensor adapted to scan a fingerprint of a user of said electronic data storage medium and to generate fingerprint scan data;
an input/output interface circuit activable so as to establish communication with the data terminal;
a processing unit connected to said non-volatile memory device, said fingerprint sensor and said input/output interface circuit,means for controlling said processing unit in a programming mode, where said processing unit activates said input/output interface circuit to receive the data file and the fingerprint reference data from the data terminal, and to store the data file and the fingerprint reference data in said non-volatile memory device, andmeans for controlling said processing unit in a data retrieving mode, which is performed subsequent to the programming mode, where said processing unit receives the fingerprint scan data from said fingerprint sensor, compares the fingerprint scan data with the fingerprint reference data in said non-volatile memory device to verify if the user of said electronic data storage medium is authorized to access the data file stored in said non-volatile memory device, and activates said input/output interface circuit to transmit the data file to the data terminal upon verifying that the user of said electronic data storage medium is authorized to access the data file stored in said non-volatile memory device.

Abstract
In an electronic data storage medium accessed by a data terminal, a fingerprint sensor scans a fingerprint of a user of the electronic data storage medium and generals fingerprint scan data. A processing unit is operable operable selectively in a programming mode, where the processing unit activates an input/output interface circuit to store a data file and fingerprint reference data obtained by scanning a fingerprint of a person authorized to access the data file in a memory device, and a data retrieving mode, where the processing unit activates the input/output interface circuit to transmit the data file to the data terminal upon verifying that the user of the electronic data storage medium is authorized to access the data file stored in the memory device as a result of comparison between the fingerprint scan data from the fingerprint sensor and the fingerprint reference data.

12. An electronic data storage medium adapted to be accessed by a data terminal, said electronic data storage medium comprising:
-
a non-volatile memory device for storing a data file and fingerprint reference data; a fingerprint sensor adapted to scan a fingerprint of a user of said electronic data storage medium and to generate fingerprint scan data; an input/output interface circuit for establishing communication with the data terminal; a processing unit coupled to said non-volatile memory device, said fingerprint sensor and said input/output interface circuit; a function key set connected to said processing unit and operably arranged such that a user is enabled to initiate operation of said electronic data storage medium in a selected one of a programming mode and a data retrieving mode by manipulation of the function key set; means for controlling said processing unit when the electronic data storage medium is in the programming mode such that the processing unit writes at least one of the data file and the fingerprint reference data into said non-volatile memory device; and means for controlling said processing unit when the electronic data storage medium is in the data retrieving mode such that the processing unit compares the fingerprint scan data entered through said fingerprint sensor with the fingerprint reference data stored in said non-volatile memory device, and transmits the data file through said input/output interface circuit to the data terminal only when the fingerprint scan data matches the fingerprint reference data. - View Dependent Claims (13)
