Why not accepted by Intelectual Property if I am the true autor and owner of the PIC?????

The test for determining whether a model release is required is whether a person would be able to recognize themselves in the image. I believe this woman would recognize herself. If she posed for you and is someone you know, ask her to sign a model release.

I personaly see no reason for IP refusal. On the other hand, technical issues can be seen.

I wonder if they made a mistake. By the way, "IP issues" is not talking about who owns the photo. It may mean

- there is a trademark or any identifiable business or brand in the photo (including clothing)

- there is a recognisable made object (building, car, sculpture) in the photo 

- that this seems to be an illustration - the illustrator must sign a form. 

None of these seem to apply - unless you did say it was an illustration.

"I am the true autor and I own the exif file to prove it."

When it's rejected because of IP, it's not because they don't believe you're the author, but because of content.

As @Test Screen Name mentioned, it's possible there is an issue with some keyword or the title, as IP is not limited to what's in the picture. Or it's too similar to some trademarked illustration, maybe.

" The person shown is a silhouette, not been able to get reconized. "

It's tricky, sometimes. I've had the same problem a while ago with a silhouette where the person was not even exactly from profile, but a little from the back.

Some say that if the person can recognize him/herself, then a model release is required. In this picture (as in mine), it could be argued that the woman could recognize herself, though it's does not seem obvious.

That said, the woman is clearly out-of-focus, so it would most likely be rejected for "technical issues" anyway.

Hope that helps,

Michael

I wonder if it's something in your title or keywords... can you let us know what they were?
