Abstract
An optical character recognition (OCR) filter described herein filters non-textual files in scanned customer data from OCR and pattern analysis of text generated thereof for sensitive customer data. The OCR filter is trained on files labelled using feature values for features generated from OCR applied to the corresponding files. Moreover, the OCR filter stores internal representations of the files during training to avoid leaking potential sensitive customer data contained therein. Once trained, performance of the OCR filter in filtering files comprising image data without text is evaluated according to false positive rates and false negative rates by comparing classifications of the OCR filter to classifications according to feature values for features generated from OCR. Evaluation of the OCR filter ensures continued model performance and informs model updates.
