This tutorial offers an insight into the world of digital authenticity and provenance mechanisms. While we have gained experience with analog solutions in the past, our current focus is on the digital level. With the proliferation of social media, deep fakes and disinformation, this topic is becoming increasingly relevant. In this tutorial, we shed light on the role of technologists, the importance of provenance and authenticity in digital media, and discuss technical approaches. Our main focus is on the use of C2PA, not only in the field of images and moving images, but also in other possible applications.

The tutorial is structured as follows:

• Provenance & authenticity: Importance in the context of digital media
• The role of technologists and research in the fight against counterfeiting
• Open standards: Introduction to the Coalition for Content Provenance and Authenticity (C2PA)
• C2PA in video sections: Our experiences with VoD, Dash and Live
• Multilayered areas of application: Where C2PA could play a role alongside image & video media
• Development status and challenges for the application areas of C2PA
• Practical examples of application and case studies on C2PA
• Future developments and trends in digital authenticity
