Combating Spoofed Robocalls with Caller ID Authentication

How Will Caller ID Authentication Help Consumers?

Caller ID authentication is a new system aimed at combating illegal caller ID spoofing. Such a system is critical to protecting Americans from scam spoofed robocalls and would erode the ability of callers to illegally spoof a caller ID, which scammers use to trick Americans into answering their phones when they shouldn’t. Additionally, consumers and law enforcement alike could more readily identify the source of illegal robocalls and reduce their frequency and impact. Industry stakeholders are working to implement caller ID authentication, which is sometimes called STIR/SHAKEN. Once implemented, it should greatly help the accuracy of caller ID information and should allow voice service providers to provide helpful information to their consumers about which calls to answer.

What Does STIR/SHAKEN Mean?

STIR/SHAKEN is a framework of interconnected standards. STIR/SHAKEN are acronyms for the Secure Telephone Identity Revisited (STIR) and Signature-based Handling of Asserted Information Using toKENs (SHAKEN) standards. This means that calls traveling through interconnected phone networks would have their caller ID “signed” as legitimate by originating carriers and validated by other carriers before reaching consumers. STIR/SHAKEN digitally validates the handoff of phone calls passing through the complex web of networks, allowing the phone company of the consumer receiving the call to verify that a call is in fact from the number displayed on Caller ID.
