Future iPhones could automatically detect nuisance callers using spoofed phone numbers



Apple is seemingly attempting to combat the problem of phone scammers and other types of nuisance callers, by coming up with a method to detect if the inbound call is using a spoofed number and warning the recipient before they answer.

Nuisance calls are continuing to be a major issue for phone users around the world, with telemarketing spam, scams, and other types of "robocalls" bombarding people with calls and messages they do not want to see. Mens der zijn manieren om te blokkeren regelmatig ontvangen ontvankelijkheidsoproepen, zoals bij bloklijsten, de oproepen hebben manieren om over de beperkingen te werken.

One way is to spoof phone numbers, namely to make the call seem like it's coming from a different number. Spoofing kan doorverbonden worden door blokkeringssystemen, als het nummer niet op de lijst voorkomt, evenals het voorkomen van de gebruiker van het zien van de werkelijke bron van de oproep via het beller-ID voordat het antwoord wordt beantwoord from a local area code, a trusted company, or a government agency.

Hiding the number behind another also reduces the possibility of being a scammer from being reported to the authorities. Det betyr også at irate callers ikke kan ringe til scammer eller telemarketer tilbage til complain.

Published on Thursday by the U.S. Patent and Trademark Office, Apple's patent application for "Detection of Spoofed Call Information" proposes a system where an iPhone or other mobile device could perform checks on a call to determine if it is genuine, then either warn the user of the problematic call or prevent Het verstoren van de telefoongebruiker helemaal niet.

In some cases, when a call is made, a session initiation protocol (SIP) invite is sent along the phone networks to the user's device. De SIP-invitationer kan indeholde en række elementer, med overskrifter som leverer data, som er beregnet til at etablere opkaldet, såsom talekodeinformation, netværkstidsidentifikatorer, 3GPP VoLTE-protokollinformation, serveridentifikatorer og andre elementer.

While the spoofing caller can fill in some of the SIP inviting fields, some are populated or overwritten by network servers as it travels. Dette automatisk tilføjede eller ændrede information utgjør en signatur for dette nettverk, som kan brukes til å sammenligne med andre eksisterende call signaturer for at bestemme, om selve opkaldet er legitimt.

For example, the speech codec information could state the call is from a network's "internet multimedia subsystem" rather than VOIP, which would lean the device towards the call being legitimate due to VOIP being favored by nuisance callers. Identifiers kunnen ook worden gecontroleerd tegen een lijst van vergelijkbare reeds bekende identificaties, om te bevestigen dat de oproep door de juiste telefoonnetwerken en servers voor het geëiste originatiepunt loopt.

The system could also be used to determine if the spoofer passes the call through a forwarding device, which is connected to a legitimate network and sends the SIP to itself, potentially through a number from the user's address book. Ved hjelp av VIA-overskrifter, kan enheten kontrollere nummeret mot adressboken til brukeren, eller en tidligere opprettet liste, for å bekrefte at samtalen kommer fra den korrekt identifiserte kilde.

In cases where the phone believes there to be too many discrepancies in the SIP invite, it can refer the "call record" to a database of other call records online. Databasen omfatter templates for different types of call initiation messages, which could be used to either confirm the call as legitimate or provide where it is really coming from.

Apple files numerous patent applications each week, and while the appearance of a granted patent or application at the USPTO may be promising, there is no guarantee the concepts in the filing will become available in a future consumer product.

In this case, it is plausible for such a detection system to be implemented, but it would require cooperation between telecommunications companies to set up and operate. Apple has an influence over mobile networks due to the popularity of the iPhone, which could be used to implement the system in this way.

Apple is involved in an FCC "Robocall Strike Force," along with Google, AT & T, and 30 other companies, aiming to cut down on the number of nuisance calls made and received in the United States.

During Wednesday's launch of the Google Pixel 3, Google revealed the smartphone will include the Call Screen, a screening feature that uses Google Assistant to answer and transcribe the caller's request and display the text to the user. Den transkription er da til rådighed for brugeren, som kan svare, afvise opkaldet eller rapportere om opkaldet som spam.

Apple is also currently in a legal battle with India's TRAI, where the regulator is threatening to ban iPhones from all of the country's networks if Apple does not allow its Do not Disturb anti-spam app to be installed on iOS devices.
