Methods of distribution and binding

In the case of StarForce Content, protected products can be distributed on optical (CD and DVD) or on any other media (USB flash drives, memory cards or portable hard drives) and over the Internet. Depending on the distribution channel, copy protection methods can be different.

Distribution on optical media

If you choose to distribute your protected products on CDs and DVDs, then the content burned on those optical media binds to the unique parameters of the disc. So the protected documents will work only with a particular CD or DVD. It renders copying or transferring the content to another disc meaningless, , as protected files will request certain parameters of the new CD that will not match the needed values. Protection against emulation and disc virtualization works similarly as described above.

Distribution over the Internet and other media

This distribution method involves binding protected content to a user device where the protected document is opened. Binding occurs during the activation of a serial number. Access to the documents can be limited by time or revoked altogether if necessary.

Business cases:

An analytics company has prepared a market report and decides to sell it over the internet using different settings, e.g. with the possibility to print and without this option. To achieve this, the company needs to encrypt the document using the StarForce Content Service and generate Serial Numbers with the appropriate settings for each type of the customer. The set of Serial Numbers can be generated in advance to be sent to customers automatically in case purchase and sale are done through an online store. When the user activates his or her Serial Number, the information about this will appear in the report section. At the moment of activation, the technical parameters of the user's PC are sent to the StarForce system. From then onwards, the protected document can only be opened on the PC where the activation took place for the first time (binding to a PC).

An educational company has created a learning course and plans to release it on CD’s with an edition of 250 copies. To protect the content, an image of the protected disk is created using the StarForce Content service. After that, the learning course can be burned on a special StarForce CD-R. In case of large circulation, a batch of CDs can be burned at the factory. The user gets access to the documents if a CD from the batch is inserted into his or her CD-ROM drive (binding to a disс).

Protection Procedure

StarForce Content PDF and StarForce Content PDF Disc protect PDF files and other documents that can be converted into PDF format (DOC/DOCX, XLS/XLSX, RTF, JPG/JPEG, PNG, GIF). First the documents are converted into PDF, and then into SFPDF format (developed by StarForce). Only a special viewer program (StarForce Reader) can open the protected documents. This program is well protected against reverse engineering and analysis, which provides a high level of resistance against tampering. Document copy protection is achieved by binding the protected documents to the end-user’s device or to an optical disc.

StarForce Content HTML and StarForce Content HTML Disc protect HTML documents and manuals (i.e. hyperlinked HTML document sets). In the course of protection, the documents are converted into a file that can be executed under Windows using the HTML Executable program. The resulting executable file contains data from HTML documents and from the built-in viewer program. A protection library is added to the file and it cannot be run without it. The executable file is protected against copying by binding it to the end-user’s PC or to an optical disc.

StarForce Content PPT and StarForce Content PPT Disc protect PPT and PPTX presentations and included video. The viewer program with an additional protection library is used for protection PPT or PPTX files. Users will not be able to open these files without it.
