As artificial intelligence (AI) has been widely adopted in a variety of applications, it is time to consider the security and privacy of AI. For example, we may wonder whether the AI model will be backdoored such that the face recognition system for access control is useless. We may also have a question about whether object detectors will be fooled such that the self-driving cars cause the accidents. We might also wonder whether the chatGPT will output illicit or discriminative contents. In this talk, we assume that the audience has certain background on AI and summarize the security and privacy issues of AI.
