Excerpt
Excerpt Col. 1 Line 65: The present invention is a fail-safe technique for ensuring a software product operates on secured customer systems, without opportunities for reverse engineering the technology that secures these products. A protection file is created that is stored in the storage media associated with a customer's software utilization-system. The protection file contains internalized attributes that characterize a specific customer system environment. ..........
Col. 2 Line 15 - 43:
When the computer software product is distributed on copyable media, the protection file must be created on the product distributor's system environment. The unique attributes of the customer's system environment are encoded within a binary file, that is sent to the product distributor by electronic mail. The binary file that is encoded during this process is not the same as the protection file that.is required for software product usage. Upon receiving the binary file, the product distributor decodes the attributes and prepares the required protection file. The product distributor sends the protection file to the customer by electronic mail, along with instructions describing where the protection file should be placed within the customer's storage medium.
When the computer software product is distributed via a communications media download, the protection file can be created directly on the customer's system environment. However, this requires encryption of the programs that prepare the protection file. These programs create the protection file by a cascade of successive steps. A parameter that is passed to the product distributor's installation program contains the required keys for decoding the programs in all steps. Each program that participates in this process:
* eliminates the previous program
* extracts the key that is required for decrypting the next program
* decrypts the next program
* invokes the next program with the remaining parameters after key extraction
