What is the MakerNote Apple 0x0002 field in iPhone/iPad images? Is it a unique identifier for photos? What is the MakerNote Apple 0x0002 field in iPhone/iPad images? Is it a unique identifier for photos?

Example:

bplist would suggest it's a binary property list.

If you can pull out the raw binary, you can decode it. There are some command line tools available. Search for bplist online.

If that fails, a discussion of the format is available here:

My guess would be that the excellent Exiftool will decode this field for you.

I maintain an image metadata software library (for Java and .NET) and would be interested in a sample image with this field. Perhaps I can add support in my software. If you have time, please open an issue and attach a sample image.
