Safein provides a unique solution for both users and merchants. Users will be able to login into websites directly with no registrations. The Safein account will at the same time provide merchants with the information necessary for client acceptance and service provision. For example, if a user is signing in to a forum, the forum usually only needs to know user’s display name or some unique identifier enabling it to separate the user from others. In this case, Safein would not disclose data like user’s full name, address, etc. Instead, it will only provide the forum with the required username. On the other hand, should the same user be buying a physical book, additionally, the merchant would be provided with user’s full name and address for shipping. Despite this, the user will have full control of his data at all times, always seeing what information is being requested by the merchant and giving a clear consent to such transfer up front.
