Abstract
A system may configure a safety-tag that indicates whether a private data area is safe to preserve. During operation, the system receives a file with a private data area. Specifically, in one embodiment, the private data area is contained within an Exchangeable Image File (EXIF) MakerNote tag, which allows makers of EXIF writers to record any desired information. Next, the system determines whether the private data area is safe to preserve. If the private data area is safe to preserve, the system configures a safety-tag to indicate that the private data area is safe to preserve. Otherwise, if the private data area is not safe to preserve, the system configures the safety-tag to indicate that the private data is not safe to preserve. Specifically, in one embodiment, the safety-tag is a Digital Negative (DNG) MakerNoteSafety tag.
