Abstract
In one embodiment, a method for sensory verification comprises exchanging at least one data item with a computing unit and selecting a sequence number. Such selection may be accomplished by generation of the sequence number or manual entry by the user. Thereafter, a transformation is periodically performed on the data item, the sequence number and optionally a random value to produce a sequence of values, each value being used to produce a perceivable sensory element for comparison with another sensory element produced by another computing unit.
