内容总结：

YouTube正式面向所有年满18周岁的用户开放AI肖像识别功能。这意味着普通用户现在也能主动监测平台上是否存在利用自己面部特征生成的深度伪造视频。该功能通过自拍式面部扫描在YouTube数据库中检索相似面孔，一旦发现匹配内容，系统会立即通知用户，用户可据此向平台提出删除请求。此前这项功能仅面向内容创作者、政府官员、记者及娱乐行业人士开放，如今全面下放至成年用户群体。YouTube表示，删除请求将根据隐私政策评估，重点考量内容是否逼真、是否标注AI生成、能否准确识别当事人等因素，但讽刺或恶搞类内容可能获得豁免。该功能目前仅覆盖面部特征识别，暂不支持声音等其他身份标识。用户可随时退出该计划并删除个人数据。YouTube发言人杰克·马隆强调，无论用户已上传内容十年还是刚刚起步，都将获得同等保护。深度伪造技术不仅威胁名人政要，普通青少年也屡遭侵害——近期就有三名青少年起诉马斯克旗下xAI公司，指控其Grok聊天机器人生成了她们的儿童性虐待素材。

YouTube正在将其AI肖像识别程序扩展至所有年满18岁的用户——这意味着几乎任何人都可以借助该平台搜索可能涉及自身的深度伪造内容。
YouTube将AI深度伪造检测工具向所有成年用户开放
这项肖像识别功能可扫描YouTube平台以寻找面部匹配内容，如今凡年满18岁且拥有YouTube账户的用户均可使用。
肖像识别功能通过采集用户面部自拍样本来监控YouTube上的相似面孔。一旦发现匹配，YouTube便会向用户发出警报；用户随后可选择要求平台删除相关视频。YouTube此前曾表示，收到的删除请求数量“非常少”。
YouTube最初面向内容创作者测试该功能，随后逐步扩展到政府官员、政客、记者，最终覆盖娱乐行业。此次向所有年满18岁用户开放是一个重大转变——它实质上赋予了普通人持续监控YouTube平台可能使用其肖像内容的权利。删除请求将依据YouTube的隐私政策进行评估，公司表示会基于以下标准考量删除权限：内容是否逼真、是否标注为AI生成、人物是否可被唯一识别。该工具对恶搞或讽刺类内容设有豁免条款，且仅覆盖面部肖像，不包括声音等其他身份特征。用户可选择退出该计划并让YouTube删除其数据。
这一消息在YouTube创作者论坛上公布，但发言人杰克·马隆表示，关于何为符合资格的“创作者”并无硬性要求。
“通过这次扩展，我们明确表明：无论创作者是在YouTube上传内容十年，还是刚刚起步，他们都将获得同等水平的保护。”马隆在邮件中表示。
深度伪造内容通常聚焦名人、政客或其他公众人物，但制作逼真数字复制品的能力同样令普通公民担忧。已有多起青少年被同学用深度伪造技术制作虚假影像的事件发生，另有三名青少年起诉xAI公司，指控其Grok聊天机器人生成包含她们的儿童性虐待材料（CSAM）。

YouTube is expanding its AI likeness detection program to all users over the age of 18 — meaning just about anyone can have the platform hunt for potential deepfakes of themselves.
YouTube is expanding its AI deepfake detection tool to all adult users
Likeness detection, which scans YouTube for facial matches, will now be available to anyone 18 years or older with a YouTube account.
Likeness detection, which scans YouTube for facial matches, will now be available to anyone 18 years or older with a YouTube account.
The likeness detection feature uses a selfie-style scan of a person’s face to monitor YouTube for lookalikes. If there is a match, YouTube alerts the user; the person then has the option to request that YouTube remove the content. YouTube has said in the past that it has found the number of removal requests to be “very small.”
YouTube began testing the feature with content creators, and then expanded it to government officials, politicians, journalists, and finally the entertainment industry. The expansion to any user 18 years or older is a significant shift — it essentially gives the average person the ability to constantly monitor content on YouTube that could use their likeness. Takedown requests are evaluated using YouTube’s privacy policy, and the company says it considers removals based on criteria like whether the content is realistic, is labeled as AI-generated, and if a person can be uniquely identified. There are carveouts for things like parody or satire, and the tool only covers facial likeness, not other identifying features like a person’s voice. Users can withdraw from the program and have YouTube delete their data.
The news was announced on YouTube’s creator forum, but spokesperson Jack Malon says there are no requirements on what constitutes a “creator” who is eligible.
“With this expansion, we’re making clear that whether creators have been uploading to YouTube for a decade or are just starting, they’ll have access to the same level of protection,” Malon said in an email.
Deepfake content often centers on celebrities, politicians, or other public figures, but the ability to create a convincing digital replica is a concern for private citizens, too. There have been instances of teenagers being deepfaked by classmates, and three teenagers sued xAI alleging that the company’s Grok chatbot generated child sexual abuse material (CSAM) of them.
