抄録
With the spread of smartphones and social media, anyone can now share media such as images, videos, sounds, and texts. Artificial intelligence (AI) technologies greatly enhance the convenience and value of social media, making it easy to analyze user preferences from a large amount of data as well as to perform media processing such as machine translation and speech-to-text conversion in accordance with user needs. However, with the evolution of AI technology and the enrichment of computer resources stemming from the ability to acquire a large amount of human-related information such as fingerprint, face, voice, body, and natural language, malicious actors can generate fake media (FM) such as fake images, fake voice data, and fake documentation that can pass for the real thing. The generation of FM has become a serious social problem.
The appearance and spread of the new coronavirus infection (COVID-19) led to the generation and spread on social media of fake news regarding preventive and therapeutic methods without scientific basis and of photographs of city scenes taken from a specific direction with a telephoto-lens camera that gave the impression of a crowded area. This "infodemic" of uncertain information can cause anxiety and confusion in society. We can easily envision an enterprising criminal group with a clear intention using AI to readily generate fake images, fake voice data, and fake documentation that can pass for the real thing and then spreading them on social media to create an infodemic. To achieve a healthy human-centered cyber society, it is essential to improve the reliability of information by appropriately dealing with such threats and, at the same time, to support diverse communication and decision-making.

This talk will outline these threats and introduce technology for users to control distribution of their own biometric data in cyberspace and technology for detecting fake media. Further, the speaker will introduce “Social information technologies to counter infodemics (CREST FakeMedia project),” which is currently being developed under JST CREST.
