Digital sovereignty is a new concept in the digital era suggesting that parties should have sovereignty over their own digital data. On an individual level, digital sovereignty demonstrates the capacity of individuals to own their personal data and control its use. According to relevant empirical privacy studies (Acquisti et al., 2015), it is very clear that individuals find it difficult to make reasoned and rational decisions on their personal data due to behavioral bias and the complexity of the issue. Moreover, individuals demonstrate significant uncertainty about the importance of privacy due to difficulties in evaluating the relevant consequences derived from the intangible nature of the privacy harms. When it comes to VET teachers / trainers and their activities, the aspects of digital sovereignty and data / privacy protection become of even higher importance. Therefore, supporting VET teachers/trainers in becoming sovereign of their digital data and in enhancing their digital security skills serves a two-fold purpose:

1. On an individual level, VET teachers/trainers will improve and enhance their knowledge and the available tools that will help them control and evaluate the use of their personal digital data and history.
2. On a societal level, VET teachers/trainers will be enabled to teach and promote safer and more responsible use of digital technology. And this is exactly where DiSCVET project steps in aiming to develop a new innovative form of training content along with an online simulation platform that will empower VET teachers/trainers throughout Europe to develop and enhance their digital sovereignty and digital security skills as well as to enrich their portfolio with relevant training materials for teaching others on digital security topics.
