The need for security systems and related ICT solutions poses new challenges to the individuals in terms of fundamental rights such as the right to privacy. Those challenges generate mistrust at the same time to the end-users. Standardisation and certification can have a significant role in changing the picture and help reinstate the lost confidence. This paper examines the concept of “trust” to ICT employed for security purposes, identifies the needs of the stakeholders and concludes with recommendations for the potential role of standardisation and certification through the implementation of a pan-European seal based on robust standards.
