Latest Patents

Helle's latest patents include groundbreaking technologies such as "Semantic search and retrieval over encrypted vector space." This patent discloses a method and system for performing end-to-end encrypted semantic search and retrieval. The system is designed to conduct semantic searches of encrypted data, utilizing product quantization and distance scores to ensure efficient and secure retrieval of relevant information. Throughout the search process, user queries, indexes, document identifiers, and document contents remain encrypted, significantly enhancing privacy and security compared to traditional search methods. This innovation is particularly beneficial for applications that depend on semantic understanding in search queries, including Generative AI and Retrieval-Augmented Generation (RAG), while maintaining strict data confidentiality.

Another notable patent is the "System and method for encrypted search using hash vectorization models." This technology employs hash vectorization (HV) models, which are secure, one-way hash indices generated through a compression process, such as the modeling phase of Lempel-Ziv (LZ) parsing. Each HV model consists of a hash filter and a chain vector. The hash filter, akin to Bloom filters, allows for the rapid elimination of negative query assessments. Following the hash filter is a chain vector that provides spatial modeling of hashed elements throughout the compressed and encrypted data, resulting in improved accuracy, efficiency, and query expressiveness compared to existing techniques.
