UNESCO, Keystones to Foster Inclusive Knowledge Societies; Access to Information and Knowledge, Freedom of Expression, Privacy, and Ethics on a Global Internet (UNESCO Internet Study) (2015) (full-text).
UNESCO has worked with Member States and other stakeholders to analyse four separate but interdependent fields of Internet policy and practice, within the mandate of UNESCO, perceived to be central to achieving this vision. These are access to information and knowledge, freedom of expression, privacy, and ethical norms and behavior online. This report assesses these four fields by viewing them as keystones for building a free and trusted global Internet that will enable inclusive Knowledge Societies. The metaphor of "keystone" refers to the architectural element which links an arch at the top, and thereby holds other stones in position. It is used to convey the importance of these four dimensions to the structure of the overarching Internet.
