The personal data and information in the era of artificial intelligence support the operation of AI systems. The importance and value of personal information in the present is self-evident. The identification elements of personal information include "identifiability" and "fixability". Personal information in the field of artificial intelligence presents different forms on this basis, including personal information collected by "intelligent objects" and analyzed by intelligent systems. While artificial intelligence infringes personal information in different situations, the infringing subject is difficult to determine under the current law. In the "intellectual era", artificial intelligence seriously threatens the security of personal information. Therefore, while the era of artificial intelligence is coming, it is necessary to provide effective legal protection for personal information security issues in the field of artificial intelligence.
