In case it would influence the answers, my home made tools are written in Java, sometimes using external tools like exiftool. extracting photos from my phone to my pc, detecting duplicates before I back things up, etc. The above is in the context of trying to automate how I manage my photos, i.e. But is there a way to extract from the JPG only the bytes representing the image, so that I can do a digest of these bytes and see that both files are actually the one and same image? Is there a way to verify that the image inside both JPG files is actually the same? I mean, if I do a digest of both files, I will obviously get a different hash.
Let's assume a JPG file (or any other image/video file format), that I duplicate the file, and I modify the tags on the copy.
