Publication number: 20260119715Abstract: Methods and systems herein identify and redact personally identifiable information. A PII sensitivity detection framework includes multiple layers where each layer corresponds to a computer model. The framework analyzes data stored within different data tables and predicts whether a data column includes PII. The first layer corresponds to an artificial intelligence model that analyzes each column metadata and predicts a first score indicative of a likelihood of PII. The second layer corresponds to a rule-based computer model that uses various rules to determine a second score indicative of a likelihood of PII for each column. The third layer corresponds to a column content model that analyzes content of each column using various natural language processing techniques to generate a third score indicative of a likelihood of PII. The framework masks data being presented to a user based on the scores generated via execution of one or more of the layers.Type: ApplicationFiled: December 17, 2025Publication date: April 30, 2026Applicant: Citibank, N.A.Inventors: Shubhanshu Gupta, Ashish Awasthi, Amaruvi Devanathan, Mallapu Raghavulu Surya Prakash
