Secret editing of EXIF data for photographs using freeware

Imagine that person you never met before approaches you in the
street and tells you he needs to falsify a document and would
like some advice on how to do it.

"What kind of document is it?", you ask.

He says, "Just a document, any document."

"How do you want to falsify it?", you ask.

"Any way at all", he answers.

"Do you want to lie about who wrote the document?"

"Maybe - but that's my business" he answers.

"Who are you trying to fool?", you ask.

"None of your business", he answsers.

"What's your name?", you ask.

"Why my name is EXIF Info. I'm the son of Mr. Gimmeyour Info and
Mrs. Whosaysitsnotmy Info.

My advice to EXIF Info is that he's probably already left an
indelible trace of himself, including a unique and traceable IP
address leading to his front door, stored in his ISP's archives
(within reach of a subpoena), asking for advice on how to falsify
evidence.

So, if I were you Mr. Info, I would take up honest work. You'd
be surprised. It's actually very satisfying, less anxiety
producing, and more fun. It produces more long lasting rewards
than falsifying data. It may even keep you out of trouble.
