Metadata in photoshop

Are there any photoshop gurus out there who know something I don't about securing the metadata in your digital files??

Has anyone been given any upto date info of how this can be done, for copyright purposes?
All can find is Picscout or Tin eye, but they still don't realy address the issue of somehow securing the data so no one can just simply remove it?

I have been bursting my brain over the last few weeks to come up with a solution, and thought I found one, but...it is still purely based on trust.
I know about watermarking and paying a fortune for encryption, but surely there is an easier way?

Anyone have any suggestions on how to send digital files, and address the copyright issue?

To the best of my knowledge, there's no effective way of securing metadata.

An alternative would be to supply ,pdf files, instead of jpegs ans pdfs have inbuild encryption and password protection. If you have the professional Acrobat, you can turn it on. Probably not unbreakable, but more robust than most.

Thanks Gggggggraph Smile

oops too many g's

I use photoshop CS3 and have only just got my head around the metadata.
So, if i save in pdf, does this lose print quality when the image is printed?
I have studied the resolution , and know my dpi from my ppi, but I can't get my head around how my 80 mg Tiff will print out ok saved as a pdf.
Does the printer decompress and upsize at the time of printing, without jeapordising image quality?

And when i save , and it asks me what quality i want to save at ( by moving the slider) I assume i am compressing the image. So what then happens to this image when it is printed?
Sorry to sound dumb.

Hi Vansprang - if you save as a Photoshop PDF, the compression scheme is JPEG, so the same principles apply: Bigger file = better quality.

You would need to open the PDF in Acrobat to set the permissions. For instance, you can prevent copying, editing or printing. On the other hand, this doesn't stop somebody simply taking a screen grab.. (Nothing can stop that.)
