MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202621023969 A) filed by Hyprofound Technologies Private Limited, Maharashtra, on Feb. 27, for 'system and method for privacy-preserving dual-store hybrid search, sectional pagination, grouping, and notifications.'
Inventor(s) include Neeraj Nathany.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to a computer implemented system and method for privacy preserving storage, search, retrieval, pagination, grouping, and notification delivery of electronic communication objects. The system employs a dual store architecture wherein sensitive content is maintained in encrypted form within a primary store, while search optimized representations are maintained in a separate search store with pseudonymized identifiers. An adaptive hybrid search pipeline integrates lexical and semantic modalities, invoking semantic search conditionally and combining normalized scores into hybrid rankings. A section aware pagination mechanism maintains per section cursors and applies ancillary markers to prevent gaps in threaded retrieval. Communication objects are organized into metadata driven hierarchies for structured grouping and stratification. A notification subsystem generates context aware payloads tailored to message type and metadata, with aggregation and user preference filtering. The disclosed system achieves improvements in processor utilization, storage input/output, network bandwidth consumption, and cryptographic processing load while ensuring privacy-preservation and efficient delivery."
