In a couple of years it will be almost any iPhone instead of 18 Pro. And if it catches on, other phone vendors will provide a similar service.
And then stop the 3rd party app which is vendor-agnostic and works on all devices?
I'd say that's unlikely.
IF that's an industry this Apple-feature will disrupt, it seems it will barely have an impact on the process of insurance companies themselves, but will actually disrupt the service-provider industry FOR insurances:
The insurance won't be able to stop their existing 3rd party cost-saving, as it provides the largest device-coverage for offloading to the customer.
Instead, either the insurance or the 3rd party service-provider will have to pay Apple in addition to make use of this feature, with the hopes that the provided data will reduce fraud.
Which brings me back to my actual question: What is the fraud-vector here?
The industry has some extensive experience in independently verifying signatures, I don't see how the manufacturers factor in here. And for app features, just ask banks how integrating biometrics, payment services, etc. goes. Tends to be preferred, once Apple and Google Pay became fully available here in Austria, banks dropped their own NFC payment solutions in rapid succession.
This will allow banks to trust these cameras more on the long run, allowing higher security ID checks.
Banks are offloading the trusted process of ID verification to an untrusted entity (end-user, merchant,...) and compensate for the loss of security by using a trusted service-provider (now Apple AND an iPhone 18 Pro).
This is already happening today in two scenarios:
1. lower-risk scenarios (remotely) with trusted 3rd party service-providers and very low Hardware-requirements ("use this app on your phone to take a picture/video") and
2. higher-risk scenarios (on-site) with trusted 3rd party service-providers ("use THIS expensive device to take a picture/video of the customer/citizen")
Apple now potentially disrupts the service-provider industry of #2 (higher-risk scenarios) by
#a grabbing a part of this hardware/service market that MAY allow the end-user to be in control of the device and
#b replacing the on-site hardware/service with an iPhone "in a box".
They can't disrupt #1 because their cost-saving can't mandate the end-user to buy a 1000+ USD device just for THEM to provide the contracted service. (They can add convenience if you have it, but they can't reject their service if you don't)
Which means they disrupt mainly #2: The industry providing trusted imaging solutions for higher-risk scenarios.
--> So it's the Watch Ultra game all over again.
On Watch Ultra they disrupted the diving-watch market by the sheer scale of selling their development to everyone buying a Watch Ultra, driving down the cost so much that they can undercut every diving-watch company on the market.
Now they use the sheer scale of iPhone 18 Pro sales to enter the trusted-imaging market-segment, undercutting every player there and take that market.
Back in the day Canon and Nikon tried this with embedded private keys on their cameras, and with Sandisk's WORM SD cards. Then, somebody extracted the keys and it was game over.
While my iPhone 17 can't match a full frame mirrorless camera, it can take pretty impressive photos, so they are already more than adequate in detail and clarity department. So making these images trusted is a huge win for them.
