Patent ID: 8279049

Claim:
A multimedia device with a remote control, comprising the remote control, comprising, a first microprocessor; a first hardware device for identifying the remote control; a second hardware device for detecting biometric data of a person; and a transmitting device for transmitting data; in combination with a multimedia apparatus comprising a receiving device for receiving the data; a memory; and a second microprocessor; wherein the first hardware device is a SIM card on which the following data is stored: a first pair of digital codes (PubK 1 , PrivK 1 ); a second pair of digital codes (PubK 2 , PrivK 2 ); a personal identification code (PIC); and personal data of at least one user; wherein the memory of the multimedia apparatus holds the following data stored after a first initialization: only one code (PrivK 1 ) of the first pair of digital codes; only one code (PubK 2 ) of the second pair of digital codes; biometric data and personal data of a user, as well as the personal identification code (PIC) encoded with the only one code (PubK 2 ) of the second pair of digital codes; wherein the second hardware device reads in biometric data of the user upon an established connection between the remote control and the multimedia apparatus; adds the personal identification code (PIC) and the other code (PrivK 2 ) of the second pair of digital codes to the biometric data, wherein the biometric data, the personal identification code (PIC), and the other code of the second pair of digital codes form a data set; encodes the data set with the other code (PubK 1 ) of the first pair of digital codes; and transmits the encoded data set to the multimedia apparatus; wherein the multimedia apparatus receives the encoded data set; decodes the received, encoded data set with the stored one code (PrivK 1 ) of the first pair of digital codes; extracts from the data set the other code (PrivK 2 ) of the second pair of digital codes, the personal identification code (PIC) and the biometric data; extracts from the memory the encoded biometric data, the encoded personal data and the encoded personal identification code (PIC) and decodes them with the other code (PrivK 2 ) of the second pair of digital codes; and compares the received, decoded personal identification code (PIC) and the decoded, stored personal identification code (PIC) with one another and upon agreement compares the received, decoded biometric data and the stored, decoded biometric data with each other and only clears the multimedia apparatus upon agreement.
