zk-Cookies: Continuous Anonymous Authentication for the Web https://eprint.iacr.org/2025/1938
Frolov et al. proposed a continuous anonymous authentication (CAA) scheme named zk-Cookies in their paper , which utilizes zkSNARKs for efficient behavior signal analysis to prevent credential sharing and theft, and supports differential privacy. Frolov等人在论文中提出了一种连续匿名认证方案(CAA) zk-Cookies，使用zkSNARKs实现高效行为信号分析，防止凭证共享和盗窃，并支持差分隐私。
Notes
- Shifts behavior signal processing to the client, reducing server data collection
- Utilizes zkSNARKs for efficient computation and privacy protection
- Supports common behavior signals such as IP addresses, geolocation, and browser fingerprints
- Prototype application for age verification based on traditional credentials
- Integrates differential privacy analysis to enhance data security
- Performance optimization, updating operations completed in 200 milliseconds
