Abstract: Various of the disclosed embodiments concern methods and systems for maintaining privacy in a machine directed workflow for the purpose of creating a set of authorized users. According to one embodiment, the system maintains privacy by dividing information associated with a user into three privacy tiers. First privacy tier is configured to authorize access to all users. Second and third privacy tiers are configured to limit access to a subset of users. Once the system matches the users and receives authorization from the users, the system creates a set of authorized users, which can freely send messages to each other, and share first, second and third privacy tiers of information with each other.
