Abstract(in English) In this paper, we deal with data anonymization as a privacy protection technology.Even in an anonymized database, it is possible to identify an individual by combining multiple quasi-identifiers.There is a need for k-anonymization technology that cannot be narrowed down to less than k people.In addition, even with anonymity, l-diversity is required so that the attributes of individual records narrowed down to the same category do not have the same information that requires special care, such as medical history.In this paper, the authors propose to replace the information corresponding to the information requiring special care with a high-dimensional face image tag (hereafter referred to as a face tag) that is difficult to retrieve directly.Although there have been studies that provide facial images with facial expressions instead of the original information requiring special care, they cannot directly show information that could be information requiring special care, such as medical history and age. Incorporating information as a high-dimensional face image that gives information indirectly, generating face tags with diversity.A third party can know the tendency of the information requiring special care from the deformation information of the face tag, but it is not generated from the base image of the individual's face, so it has no relation to the individual.
