Abstract
This application relates to a client-server architecture that enables user accounts registered with a service to be discoverable to other users of the service. A discovery protocol includes accessing personal information data stored in an address book of a client device, obfuscating the personal information data, transmitting a request to a service to determine if the obfuscated personal information data matches any potential contacts that have registered as discoverable with the service, and comparing information related to the potential contacts with the contacts included in the address book to determine if the contacts in the address book match any of the potential contacts.
