ABSTRACT:
Method, apparatus and article of manufacture for disabling on-demand access to computerized resources on a computerized apparatus. The method comprises receiving a disablement code; validating the disablement code; and disabling an on-demand resource if the validating is successful, thereby rendering the disabled on-demand resource unavailable for use by users of the computerized apparatus, wherein the disabled on-demand resource is a hardware resource of the computerized apparatus. Another embodiment includes receiving a disablement code comprising encrypted data, validating the disablement code, disabling at least one on-demand resource if the validating is successful. The validating includes generating a first key using system information unique to the computerized apparatus; decrypting the encrypted data using a second key to produce decrypted data; encrypting a value to produce an encrypted value; decrypting the encrypted value to produce a decrypted value; and comparing the value to the decrypted value.
