Chatbots in Hospitality and Travel Industries

At the Privacy Week conference in Vienna I gave a talk called;Privacy and Data Security of Chatbots.; I wanted to point out that you should consider what data to share with a bot and in which steps the data is processed when talking to a bot: How secure are the messenger apps themselves, the connection the data is transferred over, the natural language processing (NLP) and machine learning tools used, and, last but not least, the backend of the bot itself and its database?
