摘要：A secure software system includes a transformation processor for transformingan original program capable of being executed on a lessee site into a vendor serverprogram, a first program intended to be executed at the lessee site which lacks some ofthe functionality of the original program and a second program. The first programprovides some of the computation of the original program but is unable to provide all ofthe functionality of the Original Program and requires cooperation with the secondprogram which corresponds to an excised portion of the original program to provide thefunctionality of original program. The excised program is executed or otherwise utilizedby a vendor server program which, in one embodiment, is generated by thetransformation processor. With this arrangement, the lessee obtains the total
functionality of the original program without having access to the original program codeand the excised program is selected such that it would be relatively difficult to recreatethe total functionality of the original program.
