The Canadian Radio-television and Telecommunications Commission (CRTC) said in a statement Tuesday that telephone companies must now implement technology on their networks that can better eliminate fraudulent phone calls, which are calls that sound familiar. . Canadian phone numbers they might want to answer, but are actually unsolicited spam and nuisance calls from shady companies. Earlier this month, CRTC Chairman Ian Scott announced that the regulator will force phone companies to do more to crack down on those calls, which he says account for up to 25 percent of all telephone calls over mobile networks in Canada. now.
“Most people probably perceive spoofed calls as a nuisance,” Scott said in a speech at a telecommunications conference earlier this month.
“The truth is, they are more than that. They are gateways for criminals to fool hard-working people with their money and sensitive data. And they are relentless, ”he said, citing data from US Federal Communications. Commission that suggests there are over 2,100 robocalls made to phone users in the United States every second of every day.
Technology to reduce identity theft
The technology, known as STIR / SHAKEN – which stands for Secure Telephony Identity Revisited / Signature-based Handling of Asserted Information Using toKENs – will not completely block fraudulent phone calls, as it will only work on calls that go over a IP voice network. . But it will help slow down the flood.
“This new caller ID technology will allow Canadians to determine which calls are legitimate and deserve an answer, and which should be treated with caution,” said Scott. “As more providers upgrade their networks, STIR / SHAKEN will undoubtedly reduce identity theft and help Canadians regain peace of mind when answering phone calls. “
In addition to IP-driven technology, some phone companies are already experimenting with artificial intelligence technology that allows them to screen phone calls on their network that they suspect are fraudulent.
Scott said Bell Canada has tested such a system and successfully blocked 1.1 billion such calls on its network between July 2020 and October 2021.
Ultimately, the telephone industry in Canada could evolve into a system where users would see a red or green light next to incoming calls: green for calls for which the caller ID has been verified and red for others.
