The world's oldest undeciphered writing system is close to being cracked thanks to a new technology and online crowdsourcing, Oxford University researchers have announced.

Called proto-Elamite, the writing has its roots in what is now Iran and dates from 3,200 to 3,000 B.C. So far, the 5,000-year-old writing has defied any effort to decode its symbols impressed on clay tablets.

Now a high-tech imaging device developed at the Universities of Oxford and Southampton in England might provide the necessary insight to crack the code once and for all.

Comprising a dome with 76 lights and a camera positioned at the top of the dome, the Reflectance Transformation Imaging (RTI) is able to capture extremely high quality images of ancient documents.
