Secure Software Licensing Part 2

Posted by John Browne on Aug 1, 2012 4:46:00 AM

In the last blog post, we talked about what is meant by "secure" in the phrase "secure software licensing." But what exactly do we mean by "software?"software

At first blush I think most of us think of "software" as a desktop application like Photoshop or perhaps an OS like Windows. And frankly this is the bulk of what we see people needing advanced secure software licensing for. But wait, as they say, there's more:

  • Executables: Anything in the PEF (portable executable file format) can be protected against license abuse or copying. 
  • DLLs: dynamic-link libraries (DLLs) and shared libraries on MacOS and Linux can be used to store a significant amount of protectable code. 
  • Data files: files associated with particular applications may need to be protected as well. For example, PDF files (used by Adobe Acrobat) are a popular format for distrubuting electronic documents, some of which can contain sensitive information. You might want to secure the availability of these to certain people or certain time frames. Additionally, if your application uses a database of proprietary data (perhaps industry benchmarks you have painstakingly collected over the years) you might want to prevent unauthorized access or copying of that data.
  • Media files: Both music and video have multiple DRM systems in place for commercial distribution. But what if you want to stream video from your website but limit its distribution to a set of license rules? This can be difficult without a secure software licensing system. 
  • Website access: As more and more applications move into the cloud, or are presented as Software as a Service (SaaS) like salesforce.com, access control and authentication become more and more important. Current systems like named users with passwords are ripe for abuse (sharing credentials among multiple users). 
In the next article I'll dig into the term "software licensing" to discuss what is arguably the most interesting part of this concept.
