Abstract

Methods and apparatus are described for generating a gaming application signature which uniquely represents a gaming application having a plurality of gaming application objects associated therewith. A subset of the plurality of gaming application objects are retrieved. An object signature is generated for each of the retrieved gaming application objects. The object signatures are combined to generate the gaming application signature.
