Patent number: 10498766Abstract: A computer program product has a computer-readable storage medium having computer program instructions embodied therein for performing a method for implementing a privacy policy for a user. The method may include the user developing rules that determine whether another user (requester) can access information related to the user. The rules may be stored in a database coupled to a server and evaluated when a request is received from the requester to access the information. If a rule is satisfied by the requester, the server can return the information to the requester. The information can be returned at a level of granularity specified by the user in the satisfied rule. A privacy level can be set by the user to allow access to requesters based on the rules or to deny access to any requesters.Type: GrantFiled: July 5, 2016Date of Patent: December 3, 2019Assignee: Google LLCInventors: Yan Yu, Michael Chu, Chung-Man Tam, Steven Lee, Ravi Jain, Tu Tu Tsao, Christopher Lambert

Patent number: 9984164Abstract: Computer systems and methods allow users to annotate content items found in a corpus such as the World Wide Web Annotations, which can include any descriptive and/or evaluative metadata related to a document, are collected from a user and stored in association with that user. Users are able to annotate and view their annotations for any document they encounter while interacting with the corpus, including hits returned in a search of the corpus. Users are also able to search their annotations or to limit searches to documents they have annotated. Metadata from annotations can also be aggregated across users and aggregated metadata applied in generating search results.Type: GrantFiled: July 28, 2011Date of Patent: May 29, 2018Assignee: EXCALIBUR IP, LLCInventors: Eckart Walther, Qi Lu, David Ku, Kevin Lee, Chung-Man Tam, Ali Diab
