The iPhone already alerts you to “potential spam” calls. However, Apple wants to beef ups this feature even more. The tech giant has been granted a patent (number 11,095,664) for “detection of spoofed call information.”
In the patent data, Apple notes that users may get an invitation to join a phone call or a media session. The invitation may be from a legitimate caller or from a spoofing caller.
Apple’s idea is for the iPhone to check parameters using templates to evaluate a consistency of the invitation with respect to a database in the smartphone. The templates include session protocol, network topology, routing, and social templates.
Specific template data includes standardized protocol parameters, values from a database of the mobile device and phonebook entries of the iPhone. The smartphone would use such data to differentiate between legitimate and spoofed phone calls.
