1. An apparatus for producing an identification device, comprising: a capture device for capturing at least one biometric output data record (BD) having a number (n) of output data elements (b 1 -b n ) for an object; a random element generator device for producing a number k of random elements (c 1 -c k ), a production device for producing an artificial neural network, namely a bidirectional associative memory; an encoding device for combining the output data elements (b 1 -b n ) with random elements (c 1 -c k ) in order to produce at least one training data record (BD′); a training device which trains the bidirectional associative memory, such that the latter outputs the training data record (BD′) at least when the at least one biometric output data record (BD) is input; and a memory device for storing configuration data (Konf) which describe the trained bidirectional associative memory.
