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。
