European Officials to Seek Privacy Changes to Microsoft's Passport

European privacy authorities this week will outline changes it wants Microsoft Corp. to make to its Passport online authentication system to settle a yearlong investigation of its privacy policies, according to people familiar with the situation. The recommendations, some of which Microsoft is said to have advanced itself in the course of discussions with European authorities, would also target Microsoft's rivals in the so-called Liberty Alliance, which includes Sun Microsystems Inc. and several other multinational companies.
