21. An apparatus for recognizing an identifier entered by a user, the entered identifier including a first plurality of predetermined characters, the system comprising: means for receiving a recognized identifier based on the entered identifier, the recognized identifier comprising a second plurality of predetermined characters; a first memory that stores a plurality of reference identifiers, each one of the reference identifiers comprising a different plurality of predetermined characters; a second memory that stores a plurality of probabilities, each probability representing a quantification of a tendency of one predetermined character to be recognized as one of the predetermined character and another predetermined character, the plurality of probabilities being arranged in the second memory as at least one confusion matrix; a processor, in communication with the means for receiving, the first memory, and the second memory, and determining for every one of the plurality of reference identifiers a corresponding identifier recognition probability, each of the corresponding identifier recognition probabilities being determined on the basis of the plurality of probabilities stored in the second memory, the processor selecting the reference identifier most likely matching the entered identifier based on the identifier recognition probabilities; and selecting means, in communication with the processor, for selecting among the at least one confusion matrix.
