EMBODIMENTS OF A SYSTEM AND METHOD FOR SECURELY MANAGING MULTIPLE USER HANDLES ACROSS MULTIPLE DATA PROCESSING DEVICES

摘要

A system and method for are described for securely linking a phone number and user identification code in a directory database. A computer-implemented method comprising: receiving a first request from a first user device to register with a first service, the request identifying a phone number of the user device and including a fingerprint code uniquely identifying the first user device; registering the phone number in a directory service; receiving a second request from the first user device to register with a second service, the request including a user identification code which is not a phone number and the fingerprint code; registering the user identification code in the directory service; detecting that the first request and second request are from the same mobile device using the fingerprint code; and responsively linking the phone number and the user identification code in the directory database.
