Latest Patents

One of her latest patents is titled "Scalable auditability of monitoring." This invention focuses on secure auditability of monitoring processing using public ledgers, which is particularly useful for monitoring surveillance orders. The technology allows an overseeing enforcer to verify that law enforcement agencies and companies are not over-requesting or over-sharing user data beyond what is permitted by the surveillance order. Importantly, this process is designed to preserve user privacy, ensuring that the enforcer does not know the real identities of the users being surveilled or gain access to their unencrypted data. The invention also includes built-in checks and balances to require unsealing of surveillance orders at appropriate times, thereby enabling accountability and protecting users from government overreach.

Another notable patent is "Revocable and traceable blockchain rewrites using attribute-based cryptosystems." This invention provides a method and apparatus for the efficient and authorized rewriting of records already written to a blockchain. While mutable transactions will constitute a small fraction of all blockchain transactions, they are essential for compliance with privacy regulations such as the General Data Protection Regulation. This patent offers a framework for transaction-level blockchain rewrites that is fine-grained and supports revocation, featuring a novel revocable chameleon hash with an ephemeral trapdoor method, a revocable fast attribute-based encryption method, and a dynamic group signature method.
