A method for authorizing use of an information processing feature ("IPF") ( 12, 13 ) with an information processing device ("IPD") ( 14 ). The method includes receiving a data structure ( 20 ), which includes a first data portion ( 402 ) having information identifying the IPF, identifying a hash algorithm ( 405 ), and identifying an access condition ( 408 ) usable to provide a logical reference to one or more feature-enabling criteria ( 393 ). The data structure also includes a second data portion ( 404 ) having information identifying a hash value. The method further includes accessing the feature-enabling criteria, and applying the hash algorithm to at least part of the information in the first data portion to derive the hash value. Based on the derived hash value, authorization to use the IPF with the IPD is obtained.
