BACK IN TIME

An interdisciplinary research effort to build automation tools for the decryption of historical documents.

The BACK IN TIME Project

Get ready to uncover unexpected plots and secrets as old as time!

BACK IN TIME brings together expertise of researchers from three disctinct fields - Artificial Intelligence, Cryptography and History - to decipher encrypted historical letters, some of which have lain dormant for centuries! Given the sheer number of pages and the variety of symbols and rules involved, our aim is to develop software to assist or even automate the deciphering of documents from ancient, medieval and modern History.

BACK IN TIME is an Inria Exploratory Action led by Cécile Pierrot.
