Photo hosting site with true privacy and security

Photo hosting site with true privacy and security

I'm looking for a photo hosting site with following properties:
SSL usage is enforced for any access (including image data).
Access to any image data (including thumbnails) requires user being logged
in (and the specific image/album can be shared with just specific users).
To verify point 2 above:
Upload an image.
Get URL of thumbnail/image (use "View Source" or "Inspect Element" in
modern browsers).
Open Private/Anon browser window.
Try to open URL from step 2.
Expected behavior: user is prompted to login.
As an example, Flickr and Google+ Albums fail this test.
