Protection Countermeasures to Caller ID spoofing
Clearly, one should be VERY careful when speaking to someone over the phoneline unless they can prove that they are who they say they are (if a Bank phones you, then they should clearly know your financial details, etc... - but even then, this might not be enough information to the very cautious).
Anyhow, are there any **Cryptographic Methods of Caller ID spoofing protection** (or, potentially, cryptographic methods for detecting whether a call has been spoofed)? The article mentions some technical information, but it DOES NOT MENTION PROTECTION COUNTERMEASURES to Caller ID spoofing, and I really think it should.
