7. How does Sentinel LDK protect my intellectual property? 
The Sentinel Envelope is an automatic file wrapper that provides robust intellectual property (IP) protection against software reverse engineering through file encryption, code obfuscation, and system-level anti-debugging. This ensures that algorithms and trade secrets that are embedded in the software are secured against hackers.

To protect data files, the Sentinel Envelope wraps the application, encrypting and controlling access to the software data files so that only authorized users and the hosting software can decrypt and access it. The Sentinel Envelope secures your application by adding a protective shield responsible for binding the application to the Sentinel protection key, encrypting the application file, while managing and tracking the licensing information stored in the key.

9. What does Sentinel LDK have to offer in terms of software-based protection and licensing?
Sentinel LDK offers an unparalleled solution for vendors requiring software-based protection and licensing. As a means of further enhancing our security and flexibility, we are introducing two modes of operation allowing software vendors to balance licensing agility/flexibility and security.

 

  • Software vendors have the option of providing a User-Mode software-based license for Windows platforms that does not require the installation of the Run-Time Environment on the end-user’s computer. This approach allows for unmanned installations to take place regardless of the end-user’s administrative rights on the target machine, reducing any delays or additional overhead as they relate to mass deployment.
  • Additionally software vendors can provide their application to be installed requiring full administrator rights in addition to the installation of the Run-Time Environment (RTE).
