"Did a real camera take this photo?" "Did that person actually say those words?" "Did a human write this?" Answers are no longer intuition — they are infrastructure. This article maps the 2026 landscape of synthetic media detection and content authenticity in one page: standards (C2PA, JPEG Trust ISO 21617, CAI, Project Origin), watermarks (Google SynthID, OpenAI Sora watermarks, Anthropic), detection tools (TrueMedia.org, Sensity, Reality Defender, DeepMedia, Hive Moderation, Optic, Microsoft Video Authenticator), text detection (GPTZero, Originality.ai, Copyleaks, TurnItIn), Korea (KAIST, AI Open Innovation Hub), Japan (NICT, NTT DATA, AISI Japan) — who is who, what works and what is broken, and what media, security, policy, and academia need to know.

"이 사진은 진짜 카메라가 찍었나?" "이 영상의 그 사람은 실제로 그 말을 했나?" "이 글은 사람이 썼나?" 답은 더 이상 직관이 아니라 인프라가 한다. 이 글은 합성 미디어 탐지와 콘텐츠 진정성의 2026년 지도를 한 장에 담는다. 표준(C2PA, JPEG Trust ISO 21617, Content Authenticity Initiative, Project Origin), 워터마크(Google SynthID, OpenAI Sora 워터마크, Anthropic), 탐지 도구(TrueMedia.org, Sensity, Reality Defender, DeepMedia, Hive Moderation, Optic, Microsoft Video Authenticator), 텍스트 탐지(GPTZero, Originality.ai, Copyleaks, TurnItIn), 한국(KAIST·AI Open Innovation Hub), 일본(NICT·NTT 데이터·AISI Japan)까지 — 누가 누구인지, 무엇이 작동하고 무엇이 깨졌는지, 미디어·보안·정책·학술에서 무엇을 알아야 하는지.
