--- Comment #25 from Ryan Kaldari <[email protected]> --- Spent a few hours today researching EXIF filtering. First some background... We allow uploading from the following mobile browsers: * iOS Safari 6 and 7 * Android browser 3 and 4 * Blackberry 10 browser * IE Mobile 10 Of those, the vast majority of uploads come from iOS Safari and Android browser. iOS Safari 6 and 7 both strip out all EXIF data from photos except for Orientation, ColorSpace, PixelXDimension, and PixelYDimension. Android browser does not appear to strip any EXIF data. I did a random sampling of copyrighted images on the web. Most of them had no EXIF data whatsoever, but several had ColorSpace, PixelXDimension, and PixelYDimension. There are also a couple apps available for Android (like Image Privacy) that strip all the EXIF data from your photos. Given this information, we could probably block upload of all images without any EXIF data without blocking a large percentage of legitimate uploads. Such a block would not be foolproof, however, and would still allow a large number of copyvios to get uploaded. -- You are receiving this mail because: You are the assignee for the bug.
