As AI technology continues to advance, it is being increasingly used in social media and entertainment platforms to improve user experience, detect and prevent security threats, and generate engaging content. However, the use of AI in these areas also raises important ethical and security concerns, such as the protection of user data and the potential misuse of AI for malicious purposes. In this keynote, we will explore the latest trends and developments in the intersection of AI and security in social media and entertainment and discuss the potential implications and challenges of these technologies for users, companies, and society.
