Abstract
A method for supporting a tie of a chip to an electronic apparatus includes generating once a chip-specific characteristic variable in a chip, reading out the chip-specific characteristic variable by the chip, and transmitting characteristic data representing the read-out characteristic variable of the chip to an electronic apparatus.
Claims8
A method for supporting a tie of a chip to an electronic apparatus, comprising:
- generating once a chip-specific characteristic variable in a chip;
- reading out the chip-specific characteristic variable by the chip;
- transmitting characteristic data representing the read-out characteristic variable of the chip to an electronic apparatus;
- receiving at the chip identification data transmitted by the electronic apparatus;
- comparing the received identification data with the characteristic data;
- and
- deactivating at least one function of the chip if the comparison reveals no correspondence of the received identification data to the characteristic data.
4 more elements
A chip, comprising:
- a first device operable to generate once a chip-specific characteristic variable in the chip;
- a second device operable to red out the chip-specific characteristic variable within the chip;
- a transmitting device operable to transmit characteristic data representing the read-out characteristic variable of the chip to an electronic apparatus;
- a third device operable to receive identification data via the chip, which were transmitted by the electrical apparatus;
- and
- a fourth device operable to compare the received identification data with the characteristic data and deactivate at least one function of the chip if the comparison reveals no correspondence of the received identification data to the characteristic data.
