Are there any programs that read jpg file data headers?

okay my topic question may be illogical in itself, but thats okay.

I am asking if anyone knows of any programs that can take a file (.jpg file in my case) and look at the coding for any additional information.

For example, I have a picture from a cell phone and I want to see if there is any other information coded within that .jpg file to determine what kind of phone it came from or also the company.

Can you program? there are many code libraries that can do this, but you have to write the code to call into those libraries.

Otherwise, Irfanview or PhotoShop or other viewers might show "attribute" information.

There's no guarantee though that the software creating the JPG stored anything useful in the file.
