The sensitive data can be secured while remaining useful as contextual data using a secure augmentation logic. The secure augmentation logic receives sensitive data related to a plurality of entities and generates a knowledge graph that encodes relationships among the entities. The secure augmentation logic consistently anonymizes one or more entities in the knowledge graph according to a sensitive data anonymization policy. The secure augmentation logic generates a set of data representations based on the consistently anonymized knowledge graph.Type: GrantFiled: March 25, 2025Date of Patent: November 3, 2026Assignee: Cisco Technology, Inc.Inventors: Vasudha Venkatesh, Eva Hamburger, Reshmi Raj Chittette Rajappan, Saurabh Sharma
