Patent ID: 8306216

Claim:
A system for facilitating tracing copies of an implementation of a computational method, the system comprising: a computer processor; a network generator for generating, using the computer processor, a network of look-up tables representing steps of the computational method, the network being formed by using an output value of a first look-up table as an input value of a different second look-up table; a personalizer for generating a plurality of different versions of the network of look-up tables by changing at least one value in the network of look-up tables, end results of the version corresponding to a relevant domain of input values being substantially the same for each version, each version being unique so that output encodings and/or input decodings of the white-box implementations of the computational method are different in the plurality of different versions; an associator for uniquely associating each of the plurality of different versions with an individual station or a user of the station, in a computer readable memory.
