给主流编程助手做隐私评分，揭示数据安全短板
Can You Trust Your Copilot? A Privacy Scorecard for AI Coding Assistants
- 设计14项加权指标，分析法律文件与审计报告
- 最高分与最低分差20分，多数工具未主动过滤密钥
- 适合关注代码安全的开发者和企业决策者
AI编程助手快速融入开发流程，但其数据处理方式不透明，带来安全与合规风险。本文提出并验证了一种新型隐私评分卡，通过分析四类文档（法律政策、外部审计等），对五款主流助手在14项加权标准下进行评估。由法律专家与数据保护官共同制定标准及权重。结果揭示明显隐私保护层级差异，最高与最低得分相差20分。普遍问题包括：模型训练采用默认勾选式同意机制，且几乎全部未主动从用户输入中过滤敏感信息。该评分卡为开发者和组织提供可操作的选型依据，建立行业透明度新基准，推动AI领域向以用户为中心的隐私标准转型。
原文摘要 · Abstract (English)
The rapid integration of AI-powered coding assistants into developer workflows has raised significant privacy and trust concerns. As developers entrust proprietary code to services like OpenAI's GPT, Google's Gemini, and GitHub Copilot, the unclear data handling practices of these tools create security and compliance risks. This paper addresses this challenge by introducing and applying a novel, expert-validated privacy scorecard. The methodology involves a detailed analysis of four document types; from legal policies to external audits; to score five leading assistants against 14 weighted criteria. A legal expert and a data protection officer refined these criteria and their weighting. The results reveal a distinct hierarchy of privacy protections, with a 20-point gap between the highest- and lowest-ranked tools. The analysis uncovers common industry weaknesses, including the pervasive use of opt-out consent for model training and a near-universal failure to filter secrets from user prompts proactively. The resulting scorecard provides actionable guidance for developers and organizations, enabling evidence-based tool selection. This work establishes a new benchmark for transparency and advocates for a shift towards more user-centric privacy standards in the AI industry.
