Some conspiracy sites claim that this is a photo from one of the passengers on the missing Flight MH370. The specific claim is that this is a camera-original "selfie" with GPS coordinates that identify the location as the island of Diego Garcia.
The claims are false. The conspiracy is promoting a hoax.
While the GPS data does identify the location as tiny island of Diego Garcia, the metadata is inconsistent with an iPhone 5 running iOS 7.0.6. In particular, it is missing metadata fields that should be present (e.g., Makernotes and EXIF thumbnail), contains metadata that should not be present (Image Unique ID and IPTC Digest information -- both are created by applications), and has inconsistent timestamps: the "Modify Date" is 18 minutes 53 seconds after the creation date. Even the GPS information is inconsistent with the data generated by an iPhone. The metadata has been intentionally modified in order to support the hoax. For more details, see the Hacker Factor Blog.
