Google DeepMind 推出 SynthID Bio 生物安全水印技术
原标题：Introducing SynthID Bio
AI 摘要
Google DeepMind 推出 SynthID Bio，将 SynthID 水印技术扩展到合成生物学领域，用于标记 AI 生成的生物序列和结构。该技术可为 DNA 合成筛查提供自动化验证信号，帮助合成供应商识别订单是否来自带安全防护的可信模型，并协助维护 Protein Data Bank、UniProt、GenBank 等数据库的完整性。DeepMind 还将其集成到基因组模型 Evo 2 中，对设计的噬菌体基因组加水印，早期实验室测试确认其功能正常，并开源代码、体外数据和模型权重。

Strengthening biosecurity and information integrity Biosecurity relies on layered defenses – think of it like a “Swiss cheese” defense model, where multiple independent safety measures work in tandem to cover each other’s blind spots. Safeguards like model-level mitigations and customer vetting each represent critical layers with potential gaps. As a part of our broader vision for bioresilience, SynthID Bio’s watermarking approach serves as an important, tangible verification layer embedded in t
