Select what content you need to protect

Products, protected with StarForce Content, 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 over the Internet and other media Distribution on optical media
Online DRM involves binding protected content to a user device where the protected document is opened for viewing. Binding occurs during the activation of a serial number. That is why the products can be distributed online or on any media. Access to the documents can be limited by time or revoked altogether if necessary The content burned on CDs and DVDs 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

For publishers

Protection for publishers

According to the statistics rights holders lose up to two-thirds of their income, so from 100 sold copies, only 33 are sold legally and 67 copies are pirated. Training centers, publishers and authors can use the StarForce Content Service to protect the uniqueness of their products and maximize their profits.

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).
