Title: LAYERED MASKING OF CONTENT
Abstract:
Methods, systems and computer program products for layered masking of data are described. A system receives content including personally identifiable information (PII). The system redacts the content by masking the PII. The system identifies the PII in multi-layer processing, where in each layer, the system determines a respective confidence score indicating a probability that a token is PII. If the confidence score is sufficiently high, the system masks the token. Otherwise, the system provides the token to a next layer for processing. The layers can include regular expression based processing, lookup table based processing, and machine learning based processing.
