The information, known as Exchangeable Image File Format (Exif) data, has already revealed that the camera used was a Canon Rebel 350. Because the model is three years old, the device would likely have been serviced at least once since it was purchased, in which case the owner's name would be known.
The serial number itself would not necessarily give away the name of the owner, Canon said, as it can only match serial numbers with owners if the purchaser registers the device after buying it. Every time a Canon camera is serviced, however, the serial number and owner are logged together.
"In theory, we can find out which country the camera was sold in and in turn the warranty and service centre records in that country could be checked," Vic Solomon, a product intelligence officer at Canon's UK head office, said. "It would take a lot of work, but there's a good chance they could find him or her.
"From what we know, the device is one of the original Rebel cameras, probably a 350D, and given that they've been out for three years, it's likely the owner would have had it cleaned or repaired in that time."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
