Abstract: A method for applying user profiles in electronic sessions is described. In one embodiment, the method includes detecting a request to initiate an electronic session with a web server; identifying a user profile associated with the request; generating an alternative profile; initiating the electronic session; and replacing the user profile with the alternative profile during the electronic session. In some examples, the method includes performing a security action, including modifying one or more data points in a set of metadata and/or a set of latent user characteristics associated with the user profile. In some cases, the alternative profile includes a set of modified metadata and a set of modified latent user characteristics. In some examples, the method includes replacing a cookie associated with the user profile with a cookie associated with the alternative profile.

Abstract: A user creates dynamic meta-communities that span membership of multiple existing third-party online communities, based on profile attributes. This allows the user to create targeted sub-communities for specific purposes without recreating or duplicating community information. The user can communicate with members of created meta-communities by leveraging the mechanisms provided by the third party online communities.
