Investigators around the world are all facing the same problem: each holds a wealth of information, but the sensitive documents and data are entirely locked behind their organization’s firewall. There are hundreds of stories and investigations that could be done, if only these data collections were interoperable. DataShare allows for valuable knowledge about people and companies to be “sieved” into indexes and shared securely within a network of trusted individuals, fostering unforeseen collaboration and prompting new and better investigations that uncover corruption, transnational crime and abuse of power. The DataShare team consists of Mar Cabra, a fellow at Columbia Journalism School in 2009-10, and Julien Martin, both from the International Consortium of Investigative Journalists. It will be funded by the Brown Institute and supported by PBS’ investigative series FRONTLINE.
