Burning the Garden Wall: Usable Content Security for the Web

Short Form


Want to build secure and powerful applications inside your favorite web communities? Learn about application-injection, a new augmented browsing method built into the Privly application stack.


The browser extension Greasemonkey supports thousands of scripts that alter the web browsing experience. With Privly, we extended Greasemonkey’s augmented browsing from simple scripts, to application injection, meaning that we inject full applications into the host page.

Privly allows you to:

  • Build applications spanning social networks, web mail, and forums.
  • Interact with applications on websites (Facebook, Twitter, etc) without allowing them to access the content. Privacy and security are built into the stack.
  • Provide for fault-tolerance in instances where the user does not have the extension installed.
  • Build APIs spanning the user accounts of multiple online service providers.

This talk will focus on the issues and solutions surrounding injecting applications into web sites, including:

  • Methods of application injection.
  • Usability in no-boundaries ecosystems.
  • Security solutions for spoofing, clickjacking, message passing, tracking, DDOS, and phishing.
