Patent ID: 7636854

Claim:
A security device for online transaction between a service provider furnished with a computer and an operator furnished with a station of computer type, wherein the operator computer station comprising a screen and a keyboard is linked at least mediately and in an interactive manner with said service provider computer, said security device comprises: a signals reception facility devised to receive a signal originating from said operator computer station; a first read only memory of programmable type, in which a program for analyzing the signal and a program for decryption are recorded; a second read only memory of programmable type, adapted to record information specific to the operator; a microprocessor for implementing said programs and for carrying out the processing and the decryption of an encrypted signal received by the signals reception facility, by means of the information contained in the memory, and for transforming it into a code; communication means for rendering said code accessible to the operator; a biometric sensor devised to capture biometric data from the operator; a locking/unlocking facility disposed between the signals reception facility and the communication means; wherein said first read only memory of programmable type comprises a program processing program for processing the biometric information originating from the biometric sensor; wherein said signals reception facility is a photoelectric sensor and said communication means are a display cell; and wherein said microprocessor is devised to implement the processing program to generate an information item from the biometric data captured from the operator by said biometric sensor, to compare the information item with the information previously stored in the second read only memory of programmable type, to order the locking/unlocking facility in case the comparison leads to a match, to transmit said code to the communication means to render it accessible to the operator, to allow the operator to enter said code by means of the keyboard and transmit it to said service provider computer, with a view to authorizing said transaction.
