Abstract: Aspects of the present invention relate to systems and methods for generating and personalizing a profile, which may be a user account profile. In embodiments, a profile for a non-authenticated user may be generated, which may be referred to herein as a “phantom profile.” In embodiments, the phantom profile provides a means for creating and personalizing user accounts by appending data (which data may comprise content, links and IDs to data on a website or other websites, summaries, photos, one or more unique identifiers, etc.) to a profile, as well as a means for sharing and improving (adding and editing data) these profiles—whether or not the user is an authenticated user of the services associated with the user account.

Abstract: Disclosed are embodiments of systems and methods that allow for the robust, flexible, and efficient sharing of content. In embodiments, content items may be associated with metadata, third parties may be associated with metadata, and sharing with the third party may be based upon comparisons of the metadata associated with the content items and the metadata associated with the third parties.
