Data ownership and access



Some vendors have developed proprietary viewers for files to protect their information in use -- a version of "security by obscurity" -- while others implement extensions for browsers or productivity tools, such as document editors and electronic spreadsheets, which are able to decrypt file content as needed. Many of these solutions have additional features allowing data owners to apply centralized policies or user rights to individual files, where each file can have permissions setup for "view-only," "view and print" or "disable printscreen" and combinations of those functions.

In the best of these solutions, the encryption keys and permissions are stored on a proprietary server and get securely downloaded on demand. Those permissions can be removed even after the document has left the enterprise perimeter and changes take effect immediately, allowing the owners to maintain control of the content.

Watermarking

However, IRM alone does not provide protection from data thieves who use video equipment or screen capturing techniques to get illegal copies of documents. IRM needs to be combined with robust watermarks where it can enforce read-only access to the file content. This type of digital watermarking has proven to be an effective deterrent against data theft with in-house as well as SaaS solutions.

Curtains

Other vendors have recently started offering technologies that obscure the document view so only a small area around the mouse cursor is visible. This type of functionality might also close a curtain over the browser when the focus is lost to protect from screen capture or what some call "shoulder surfing."

While the curtain is useful against older screen capture technologies and is not as intrusive, it does not always protect from newer screen capture products that have built-in capturing delays. From a user perspective, curtain technology obfuscates your view to the point it is either annoying or even unusable (in the case of complex diagrams). This kind of protection often punishes legitimate users and is doing very little to protect the data, so it should be implemented with care and at least be configurable.

In conclusion, good IRM deployment will protect against all accidental document leaks both inside and outside the enterprise with on-the-fly decryption of files. Robust watermarking combined with granular access control and auditing capabilities will deter most data thieves.
