New Office locks down documents

C|Net | at | by Mike

As digital media publishers scramble to devise a foolproof method of copy protection, Microsoft is ready to push digital rights management into a whole new arena--your desktop.

Office 2003, the upcoming update of the company's market-dominating productivity package, for the first time will include tools for restricting access to documents created with the software. Office workers can specify who can read or alter a spreadsheet, block it from copying or printing, and set an expiration date.

The technology is one of the first major steps in Microsoft's plan to popularize Windows Rights Management Services, a wide-ranging plan to make restricted access to information a standard part of business processes.
