What is this event?
HENNGE TECH SYNC. is an open forum event to discuss technology.
The second HENNGE TECH SYNC. theme is Verification & Validation on the Future of Security from a Science Fiction Perspective. We will have a talk session on SF-based analysis and security with Yuya Takashima and Ichijo Takeda as guests.
Cutting-edge science fiction works depict evolved cyberattacks and advanced defense technologies, offering insights into real-world security challenges. For example, the science fiction anime Ghost in the Shell features cyber offense and defense technologies like “Attack Barriers” and “Substitute Barriers,” illustrating the never-ending battle where security evolves in response to technological progress.
The event explores the intersection of SF-based Verification & Validation perspectives and real-world security expertise, providing insights that corporate decision-makers and engineers can apply to their business strategies.
Who is this event for?:
- For those who want to gain hints for new risk countermeasures from both SF-like future insights and current security challenges
- For those who are interested in science fiction prototyping and innovative ideas
- For those who want to learn the latest security knowledge
- For those who want to incorporate science fiction prototyping into their company to improve creative problem-solving skills
