This document discusses two types of "digital fault lines" - access fault lines and trust fault lines. Access fault lines refer to the global uneven access to digital technology and connectivity. Efforts are being made to reduce this digital divide and connect the next billion users, including building new infrastructure. While mobile access has helped increase connectivity, many challenges remain. Trust fault lines refer to issues with trusting technology companies with our data. There is a lack of accountability and responsibility on the companies' part. Increased certification of products and regulation of data use could help address trust issues and reduce the cracks in the digital fault lines.
