iMessage Contact Key Verification Added in iOS 17.2 and macOS Sonoma 14.2 Betas

In addition to the new Journal app, the iOS 17.2 and macOS 14.2 updates add support for iMessage Contact Key Verification, a feature that Apple first previewed in December of last year.

Apple advanced security iMessage Contact Key Verification screen Feature
Designed for those who face "extraordinary digital threats," such as journalists, human rights activists, and government officials, iMessage Contact Key Verification allows people to verify the identify of the person they're corresponding with. It is available today in the iOS 17.2, iPadOS 17.2, macOS Sonoma 14.2, and watchOS 10.2 betas.

iPhone, iPad, or Mac users who have iMessage Contact Key Verification enabled will be notified if a malicious entity somehow succeeds in breaching cloud data servers and is able to eavesdrop on a conversation.

The feature also includes a Contact Verification Code that can be used in person or on FaceTime.

With iMessage Contact Key Verification, users can choose to further verify that they are messaging only with the people they intend. Contact Key Verification uses Key Transparency to enable automatic verification that the iMessage key distribution service returns device keys that have been logged to a verifiable and auditable map. When a user enables Contact Key Verification, they will be notified about any validation errors directly in the Messages conversation transcript and Apple ID Settings.

For even higher security, iMessage contact key verification users can compare a Contact Verification Code in person, on FaceTime, or through another secure call. They can also choose to create or edit a contact and save a public key to turn on CKV with that person.

To use iMessage Contact Key Verification, all devices signed into an iCloud account must have the iOS 17.2 beta, macOS 17.2 beta, and/or watchOS 10.2 beta.

I can’t imagine who would use this useless feature. Idk
I'm always puzzled by this kind of comment. It's not because it's a niche feature or that you personally don't have any need for it that it makes it useless. Especially if it's an optional feature. Just don't use it, some people will be happy to have this option.

A great example of me, myself and I

This is fantastic.

With AI / impersonation on a rampant rise for scamming, being able to know if you’re really hearing from your family member etc will become critical.

I can see this being extended to customer care / business purposes as well.

As we enter an age where trust will be eroded, having these tools is welcome news.

Jeff Bezos needs it.

His what’s app was hacked by Saudi Arabia and they gained access to his phone and were able to discover he was cheating on his wife. This then was leaked to the press. She filed for divorce and his net worth dropped by nearly half. Whoops!?

I plan to try it out with my wife. Need it? No. Interested to learn more about security? Yes.

I wonder what a typical day is like for people who legitimately need this? I wonder if it is more mundane than I’d think, or I wonder if it would be like a spy movie where you sneak secrets on an sd card in a Rubik’s cube or hide razor blades to cut free from zip ties in the leather back pocket patch of Levi’s.
Actually there is a lot of people who would benefit from this in the real world, in particular people in places where being a jounalist is just plain dangerous by having your phone intercept by some malicious entities without knowing.
