Latest Patents

Cook holds a patent for "Privacy-preserving dataset sketches that can be joined non-interactively." This invention discloses computer systems and associated methods that enable the non-interactive joining of privacy-preserving dataset sketches. In this patent, an entity can publish a one-time sketch of their dataset, allowing another entity to join their data without exposing private information. The sketch utilizes a hash function to map identities associated with a first value of the dataset to a data structure. Furthermore, a same or different entity can join the first sketch with a privacy-preserving second sketch of a second dataset that includes added noise. This method allows for estimating the number of identities corresponding to specific values of both datasets from the joined dataset. The sketch can be published just once, eliminating the need for separate new private computations with privacy budgeting for each additional party when a join is desired.
