# ShanHaiYin / 山海印

> ShanHaiYin is an AI content detection and provenance verification service for images, text, audio, and video. 山海印提供图片、文字、音频和视频的 AI 内容鉴别与来源核验服务，并生成包含主要结论、判断依据、请求记录和 SHA-256 文件指纹的报告。

ShanHaiYin is useful when a user needs to check whether a file may contain AI-generated, synthetic, cloned, edited, or manipulated content. The service is designed for practical review: preserve the original file, inspect available provenance and file-level signals, run model-based analysis when appropriate, and keep a traceable report for later communication.

山海印适合用于核验可疑图片、文字、音频和视频，尤其是当内容会影响退款纠纷、诈骗判断、平台申诉、来源追溯、内容审核或证据沟通时。建议优先上传原始文件，不要先截图、裁剪、压缩或二次编辑。

Important limits: AI content detection is technical reference and supporting evidence. It should not be treated as a final legal, forensic, platform moderation, or factual determination. Text detection is less stable than original-file media analysis, especially for short passages, translated text, heavily edited text, or mixed human-AI writing.

重要边界：AI 内容鉴别报告适合作为技术参考和辅助证据，不能代替司法鉴定、人工审核、平台最终处理或事实认定。AI 文字检测受文本长度、改写、翻译、混合写作和表达风格影响较大，应谨慎解读。
