For some embodiments, there may also be many other gatekeeping controls, such as frequency and precedence controls that will affect how the system queues up information from partners for the user's life view—which will be a key control in promoting partners to only push the information that really counts, while the user receives only the information that really counts.
In general, gatekeeping features are different from security in that they determine how information is delivered and displayed to the user's life view. This includes controlling the frequency, extent, type, and volume of filtered information that is pushed by the partner. This is where the marketplace implementation becomes important. When a user wants to allow information for a specific attribute to be sold in the marketplace, but no information is delivered for that attribute, then the security settings would allow visibility in the marketplace, and the gatekeeping settings would not allow information delivery to the portal (or when surfing to external sites).
