Generating a modified protected file is disclosed, including: renaming a primary content object of a protected file; and creating a modified protected file based at least in part by inserting into the protected file a replacement object for the renamed primary content object. Using the modified protected file is disclosed, including: determining that a file includes a renamed primary content object; and redirecting a data access operation to the renamed primary content object.

Generation and use of a modified protected file

Disclosed are systems and methods for context-based dynamic information rights management (IRM) in a cloud-based document management environment. A system may include a document server configured to store a plurality of documents. The document server is coupled to an information rights server and a plurality of client computer systems via a network. One or more of the document server and the information rights server may be cloud-based. The information rights for a document stored in the document server may be determined by the information rights server based on context parameters associated with a request to download the document from the document server.

Context-based dynamic information rights management

Generating a modified protected file is disclosed, including: creating a modified protected file at least in part by embedding a protected file into an at least partially unprotected file; and modifying a set of content type information included in the at least partially unprotected file to include a content type associated with the protected file as embedded. Using the modified protected file is disclosed, including: receiving, using a processor, a data access operation to an at least partially unprotected file; determining that the at least partially unprotected file includes a portion associated with a content type associated with embedded protected content; and redirecting the data access operation to the portion of the at least partially unprotected file associated with the content type associated with embedded protected content.

Methods and systems for rendering watermarks in a computer system are provided. One technique renders a content unit based on a call from an application, and renders a watermark for the content based on a call from a tool separate from the application. Another technique for rendering a watermark for content displayed on a display screen renders the content via a content window on the display, and renders the watermark via another window on the display that overlays at least a portion of the content window.
