Introduced the concept of partially blind signatures as a cryptographic technique to combat fraud in event reporting while preserving user privacy. The post details how blind signatures can obscure individual requests by having signers not see the original data, and how using different blinding factors for each step in a user journey prevents linkability across requests. It also suggests that browsers or operating systems could facilitate this process to enhance security and privacy by managing nonces and blinding factors on-device and handling signature requests out-of-band.
