Abstract:
A method of generating a number within a random sequence of numbers using a device comprising a charge coupled device array, the method comprising the steps of:a) sensing, with a first imaging transducer of the charge coupled device array, a first signal to provide first data indicative of the first signal, wherein at least a portion of the first signal comprises noise presented to or from within the first imaging transducer;b) sensing, with a second imaging transducer of the charge coupled device array, a second signal to provide second data indicative of the second signal, wherein at least a portion of the second signal comprises noise presented to or from within the second imaging transducer;c) determining a first value from the noise portion within each of the first data and the second data;d) sending, with a third imaging transducer of the charge coupled device array, a third signal to provide third data indicative of the third signal, wherein at least a portion of the third signal comprises noise presented to or from within the third imaging transducer;e) sensing, with a fourth imaging transducer of the charge coupled device array, a fourth signal to provide fourth data indicative of the fourth signal, wherein at least a portion of the fourth signal comprises noise presented to or from within the fourth imaging transducer;f) determining a second value from the noise portion within each of the third data and the fourth data; andg) generating the number within the random sequence of numbers by modifying the determined first value using the determined second value.
