“The right to be forgotten” is the right to take measures to prevent the further spread of personal information in the network, in order to realize the forgetting of personal information objectively. As a new type of right derived from the internet in the era of big data, the right to be forgotten has been separated from the traditional privacy right and has become an important part of the personal information right. Within the framework of personal information protection legislation in China, the subject of personal information can exercise the “right to be forgotten” to delete the information of illegality and uselessness, so as to protect the value orientation of personal interests, but it can be an exception in the academic field of historical research.
