摘要
Method and apparatus which restricts software, distributed on magnetic media, to use on a single computing machine. The original medium is functionally uncopyable, until it is modified by the execution of a program stored in a tamper proof co-processor which forms a part of the computing machine. The modified software on the original medium may then be copied, but the copy is operable only on the computing machine containing the co-processor that performed the modification.
