Personal phone number privacy-preserving models for public use

Abstract The importance of personal mobile numbers has dramatically increased in recent years. Most of social network’s apps today required a validated personal mobile number to register in their services. Publishing a person’s mobile number may lead to a privacy and security violation. In this paper, we describe how a person’s mobile number could easily be used to violate a user’s privacy. We study possible concerns and risks associated with publishing a user’s mobile number, and we propose an alternative: Virtual Mobile Number Model (VMNM) that links a user’s real mobile number with a virtual mobile number to help secure individual privacy. Telecommunication Service Provider (TSP) present privacy management system that sets up the connection between callers. Finally, we evaluate the model and explain how it helps to protect the user’s privacy as well as prevent personal data from being violated.
