  • Techniques for sharing content information with members of a virtual user group in a network environment without compromising user privacy
    Patent number: 7822812
    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.

  • Method for creating user profiles
    Patent number: 6701362
    Abstract: A method for creating personalized user profiles using a client computer. A client computer executes a method which monitors user activities and collects content and context information based on the monitored user activities. The client computer processes the content and context information to determine concepts of interest to the user and the user's level of interest in the concepts. Information related to the concepts and the user's interest level associated with the concepts is used to create a personalized profile for the user on the client computer.

  • Techniques for identifying and accessing information of interest to a user in a network environment without compromising the user's privacy
    Patent number: 6581072
    Abstract: Techniques for identifying and accessing documents (e.g., web pages) of interest to a user in a network environment without compromising the user's privacy. A user system receives index information comprising information related to documents stored in a network environment. The index information is then used to identify and access documents of interest to the user. The identification of documents of interest to the user is performed on the user system thus obviating the need to provide any information to search engines executing on remote servers. The present invention preserves user privacy by controlling and minimizing the communication and collection of user-related information from the user system. Merely by way of example, the present invention allows users to identify and access web pages from web servers coupled to a communication network such as the Internet without compromising user privacy.
