Title: Innovations of David Bruce Cousins

Introduction

David Bruce Cousins is an accomplished inventor based in Swansea, MA (US). He has made significant contributions to the field of secure data processing through his innovative patent. His work focuses on enhancing the efficiency of string searches in encrypted environments, which is crucial for maintaining data privacy and security.

Latest Patents

Cousins holds a patent for "Efficient secure string search using homomorphic encryption." This invention allows for the efficient search of a target string by a query string within a homomorphically encrypted space. The target string is encoded by reordering its characters into multiple target substrings, which encode non-sequential characters separated by a periodic stride K. Different target substrings have stride sequences that are offset relative to each other. The query string is similarly encoded into multiple query substrings, each defining a repeating sequence of different character values. These substrings are then homomorphically encrypted and hashed. The hashed encrypted target and query substrings are compared to determine if there is a match. A rolling hash iteratively updates the hashed encrypted target substrings, allowing for repeated comparisons with each update.
