As digital technologies penetrate every area and domain of the public sector, society investigates the extent to which regulation is needed to ensure that this new phenomenon is an advantage rather than a threat. This Track discusses privacy, security, legal informatics, and the ethical dilemmas associated with the proper use of the “traditional”, as well as the use of frontier and disruptive digital technologies such as AI, IoT, DLT, Blockchain, Big Data processing, among others. Emphasis may be placed on privacy protection and security, both regarding traditional regulatory frameworks, such as GDPR or ISO 27000, or self-regulating approaches, practices, and technologies to promote privacy protection and security in digital governance. As digital technologies have a significant impact on legislation creation and access, there is increasing interest and emphasis on “digitisation ready” legislation, legal text mining, legal XML standards and models, legal ontologies, as well as further argumentation and reasoning models and approaches towards more automated legal services and information systems. New tools, practical and theoretical approaches, frameworks, and case studies concerning the ethical and secure use of digital technologies that respect privacy are also part of this Track.
