占 16 字节:曝微软 Win11 画图 / 照片向 AI 生图嵌入 128-bit 隐藏标识符_我的网站

A | The Chang'e-7 lunar probe is scheduled for launch at an appropriate time, according to the China Manned Space Agency (CMSA).
The combination of the Chang'e-7 lunar probe and the Long March-5 Y14 carrier rocket was transferred vertically on Wednesday to the launching area at the Wenchang Spacecraft Launch Site in south China's Hainan Province, the CMSA said.
The lunar probe and rocket had arrived at the launch site in April and July, respectively, and have since completed assembly and testing. The CMSA said all facilities and equipment at the launch site are in good condition, and the functional checks, joint test and propellant filling will be carried out before the launch as scheduled.
The Chang'e-7 mission aims to achieve breakthroughs in multiple key technologies, such as high-precision soft landing on the lunar surface, legged movements, hopping and exploration of permanently shadowed craters.
According to the CMSA, the mission will employ a comprehensive detection approach, which involves orbiting, landing, roving and hopping to conduct environmental and resource surveys of the lunar south pole. It will also involve international cooperation.
。 8 月 26 日消息,科技媒体 NeoWin 昨日(8 月 25 日)发布博文,报道称安全研究员 Xusheng Li 通过逆向分析,发现微软画图(Paint)和微软照片(Photos)会把 GDID 标识符嵌入到 AI 生成的图片中。注:GDID 最早于今年 7 月报道,在针对 19 岁黑客的 39 页联邦起诉书,指出微软承认在 Windows 11 系统中,内置全局设备标识符(Global Device Identifier,简称 GDID),且没有完整关闭选项。全局设备标识符是微软用于识别某次 Windows 安装实例的持久设备级标识,可关联实体设备或虚拟机,并在部分微软服务中作为统一识别键使用。典型场景包括设备目录登记、跨设备服务协同、更新分发与企业级状态上报。GDID 以 128 位数值(128-bit value)占用 16 字节(bytes),在微软画图和照片的相关功能中,微软服务器似乎会为提示词分配这类标识符。即使 Copilot 在本地生成图片,用户输入的提示词仍可能先发送至微软服务器。Li 分析微软画图应用的 AI 功能时,发现了 Watermarker.dll 组件。画图本身已经提供可见水印选项,可以在生成图片上添加小型 Copilot 标志;但研究员发现,另一套隐藏水印功能独立于该选项运行。研究还称,微软会把 C2PA 内容认证(C2PA Content Credentials)添加到 AI 生成图片中。

B | 李旭升发现,同一个 watermarkId 也会出现在 C2PA 元数据中,作为一种“软绑定”值,用于关联图片像素中的隐藏水印与图片来源元数据。

C | 微软照片也包含 Watermarker.dll。

D | 研究员发现,照片中的本地 Image Creator 和 Restyle Image 功能似乎同样会向生成图片嵌入 GDID。相关阅读:。
