Wireless carriers are stepping up the fight against spam calls with a new technology which identifies solicitation and scam numbers…
For anyone who feels like spam calls keep increasing in frequency, it’s not bad intuition. The Wall Street Journal came across a recent report which reveals Americans received 26.3 billion spam calls last year alone. That’s up sharply, by 46 percent, over 2017.
In fact, spam robocalls accounted for 26.3 billion outgoing calls last year for American consumers, representing an increase of 46 percent over 2017.
Mobile Carriers using SHAKEN-STIR Technology to Identify Robocalls
Although the national Do Not Call Registry came into existence in 2003, the volume of robocalls continues to grow, year after year. In fact, the Federal Trade Commission reports taking a whopping 500,000 complaints per month about spam calls.
A big reason for the steep rise in spam calls is due to the fact they work. At least, when neighborhood spoofing is part of the equation. (A technique which involves faking local area codes and prefixes — increasing the likelihood people will answer or return such calls.)
Often, neighborhood spoofing spam numbers actually get calls back from unsuspecting recipients.
How Mobile Carriers Plan to Stop the Robocall Scourge
This system uses the SHAKEN/STIR or “Secure Handling of Asserted information using toKENs” and “Secure Telephony Identity Revisited” protocol:
“SHAKEN/STIR verification lets consumers know that an incoming call is really coming from the number listed on the caller ID display. While authentication won’t solve the problem of unwanted robocalls by itself, it is a key step toward giving customers greater confidence and control over the calls they receive.”
Basically, the system matches up known legitimate numbers from fakes. It essentially validates incoming phone numbers to ensure they originate from genuine sources.
The FTC reports it receives nearly 400,000 robocall complaints per day. That works out to an astounding 146 million per year.
