MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641049850 A) filed by Ms. K Ashika Jebalin; Dr. Sanjith S; and Dr. A. Shalini Divya Prasanna, Vadakankulam, Tamil Nadu, on April 19, for 'a system and method for secure encrypted data pattern analysis using adaptive multi-layer cryptographic processing.'
Inventor(s) include Ms. K Ashika Jebalin; Dr. Sanjith S; and Dr. A. Shalini Divya Prasanna.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a system and method for secure encrypted data pattern analysis using adaptive multi-layer cryptographic processing. The invention comprises an encrypted data intake interface configured to receive encrypted files, encrypted communication streams, encrypted transactional records, protected telemetry, and cryptographically secured digital artifacts from one or more sources. A pre-processing module organizes the received encrypted data according to temporal and contextual associations, and a secure feature extraction layer derives non-plaintext analytical attributes including ciphertext block distribution characteristics, entropy variation indicators, repetition density markers, segmentation patterns, timing signatures, packetization features, session continuity states, relation structures, and contextual execution observables. A pattern synthesis engine generates composite encrypted behavior profiles, which are compared by an adaptive correlation engine with reference models, historical baselines, suspicious activity templates, and contextual operational models. A decision engine generates anomaly scores, encrypted behavior classifications, deviation summaries, and response recommendations, while an immutable audit module stores analytical lineage and decision outcomes in tamper-resistant form. The invention enables confidential, scalable, and policy-aware pattern recognition in encrypted digital environments without requiring unrestricted decryption of underlying plaintext content."
