ScoreShield 为 AI 相似度分数提供隐私保护

研究人员开发了 ScoreShield,这是一种旨在保护从向量嵌入派生的相似度分数隐私的新型机制。发布这些分数(对于检索增强生成 (RAG) 和生物识别等应用至关重要)的传统方法存在泄露敏感信息的风险。ScoreShield 通过应用差分隐私高斯噪声来解决此问题,该噪声根据分数发布的全局敏感度进行校准,然后将结果投影到余弦对象的可行集上。与朴素的加噪相比,这种方法显著减少了失真并提高了效用,为 RAG、面部识别和推荐系统等任务提供了更好的性能。 AI

影响 增强了依赖向量嵌入和相似度分数的 AI 系统的隐私性,有可能提高敏感应用中的信任度和采用率。

    ScoreShield:相似度得分的差分隐私发布

    A growing number of applications, such as biometrics and retrieval-augmented generation (RAG), rely on cosine similarity scores computed between vector embeddings of text, images, or audio. These systems return similarity scores through their APIs for ranking and verification. Ho…
