The concept of "Information Integrity" has been increasingly employed towards a propositive agenda that aims to encompass the addressing of disinformation, misinformation, hate speech and threats for democracy in the online environment (see, for instance, the recently-launched United Nations Global Principles For Information Integrity). Nevertheless, it still lacks a solid theoretical framework. Joining forces, the DC on Platform Responsibility (DCPR) and the DC on Internet Rights and Principles (IRPC) organize this session to explore the concept from a perspective of human rights and platform responsibilities. The session clearly states challenges for trust and security in the current digital information ecosystem, including those related to algorithmic recommendation systems and the attention economy. The session also aims to evaluate and support the ongoing activities of all stakeholders toward strengthening information integrity, for social media platforms particularly how to live up to their responsibility while complying with human rights principles. A 90 minute roundtable is instrumental to allowing meaningful interactions with the large number of stakeholders participating in the session.
