I'm concern that someone with physical access to my iPhone as well as knowledge of my PIN could have done that.

By looking at my iPhone, is there a way to figure out if my iPhone has been imaged / accessed or backed up to a third party computer (via iTunes) ?

  • Welcome to Ask Different. I’ve added a brief answer to cover a casual effort. How much time, money, effort would you consider reasonable to learn if this happened? You could hire a forensic investigator and lawyer to get all this data and not have to learn anything. That would be overkill if you just were curious.

Does that person know your passcode?

If not, then no.
You need passcode or fingerprint before the phone will trust the computer.

From comments - If they did know the passcode, there is no way to tell.
Giving someone your passcode or Apple ID password is almost the same as giving them your ATM card & PIN, if not worse. They can do what they like, because every system they interface with will think it is you.

  • yes presumably that person know my passcode

  • Yes but nevertheless it is possible to know if you have a backup on icloud, so I was wondering if there could be a trace on the iPhone of Itunes Backup or history of connected or trusted computer

In general, this will be difficult on the phone itself since you’re trying to forensically reconstruct past events from log files that expire routinely. The easiest thing would be to take your phone to each computer you suspect and see if there’s a pairing record or backup stored on the filesystem.

Each phone makes it’s own folder, so you might see two phones backed up to a computer you only expected one.

A pairing and backup surely leave log messages on iOS, but since you can’t easily inspect those, you would need Xcode to open the console and read the log files from the phone.
