If the exif can be stripped, then it can also be edited, seems like a way to establish false data.

Yes, I changed the date from April 6 to April 7, checked it against my exif reader, and it read out everything right except the date, had an 07 instead of 06. There were two places for it, so I changed both, then used find to see if I could find the same pattern again and couldn't. I was also able to see EXIF.

If I fooled around with it more, I might be able to pick out and change the other numbers. Will work on it, I like challenges, some other time.

A possible clue it has been tampered with. The original I did a get info and saved it on April 6, same evening it was taken and emailed to me from miles away. My copy I made to experiment with says created today.

Now I can fix that second date by changing the date on my computer. I'm not completely used to this mac yet so don't want to change too much like I could easily with Windows.

If I open it and just save it again under yet a different name, it changes all the dates to today. but preserved the rest of the exif.

I see how you can easily clean off the exif on this mac. Er no, I can't. There is a check in the box for exif when I go to save it. If I uncheck it and save under yet another name, all it does is change the orientation, preserves all the other original EXIF info. I thought you maybe could strip it off that way, but you still need a photo editor. iPhoto might do it or I could tinker around with various formats just using find, double clicking on the thumbnail and resaving in the various formats, then checking for exif. .bmp used to strip it off, also .tiff Ithink, but may preserve it now. That's one problem I've had making an album using some photos I saved in .bmp (.tiff takes up huge memory) and moving them over to the mac, exif is gone. So I go back to the original which I always preserve unedited and get it that way.

So an exif stripper might be more intuitive and useful for my son, but I have no need for one.
