Abstract
Techniques for sharing content information between members of a virtual user group without compromising the privacy of the members. A user can identify content information to be shared with other members of a virtual user group using a user computer system. The content information is then communicated to the other members of the virtual user group and can be accessed by members of the virtual user group in such a manner that the privacy of the user and of the other members of the virtual user group is not compromised. The present invention preserves user privacy by controlling and minimizing the amount of user-related information available/accessible to server systems hosting the virtual user groups.
