Information-Theoretic Privacy

Information

The core concept revolves around quantifying the leakage of sensitive data, particularly within cryptographic systems and decentralized environments. It leverages Shannon’s information theory to measure the amount of information an adversary can gain about private inputs or states, such as transaction details or trading strategies, from observing public data or system behavior. This framework moves beyond traditional notions of privacy, focusing on the probabilistic nature of information disclosure rather than absolute secrecy. Consequently, it provides a rigorous, mathematical basis for assessing and mitigating privacy risks in complex financial systems.
