Abstract (en)
[origin: WO9842098A1] A digital product is freely distributed through uncontrolled channels in encrypted form (108). Security fragment(s) of the encrypted product are withheld (102), and provided only upon communication with license server (104). The customer uses reader software (106) to purchase a license. Such software (106) examines components then present on the reader system to develop a reader system signature, which the license server (106) uses to encrypt the product decryption key and the security fragments before sending them to the reader system. When the customer wishes to use the product, a new reader system signature is generated and used to decrypt the product fragments.
