Hello everyone. My name is Tobias Gondrom. I'm the Chief Technology Officer for security at Huawei. And it's a great pleasure and honor for me to welcome you all to join me at the Mobile World Congress in Shanghai this year. I will have the honor to chair the Data Security Summit on June 28th. With a number of interesting speakers and panels, we will discuss all kinds of topics around security, be it privacy for data in motion, and be it data legislation and regulation, how to use security as a competitive advantage going forward, how to manage data breaches and identify them. Again, welcome you to the Data Security Summit on June 28.
