ABSTRACT:
An apparatus for the electronic generation and comparision of non-predictable codes. The appartus of the invention comprises a first mechanism for calculating a first non-predictable code according to a predetermined algorithm, the first mechanism for calculating including a first mechanism for inputting a unique static variable into the predetermined algorithm; a first mechanism for automatically defining a first dynamic variable according to the interval of time in which the first mechanism for inputting is activated, the first mechanism for automatically defining including a mechanism for automatically making the first dynamic variable available to the predetermined algorithm of the first mechanism for calculating; a second mechanism for calculating a second non-predictable code according to the predetermined algorithm, the second mechanism for calculating including a second mechanism for inputting the unique static variable into the predetermined algorithm; a second mechanism for automatically defining a second dynamic variable according to the interval of time in which the second mechanism for inputting is activated, the second mechanism for automatically defining including a mechanism for automatically making the second dynamic variable available to the predetermined algorithm of the second mechanism for calculating; and a mechanism for comparing the first non-predicatable code with the second non-predictable code.
