OCR is a commonly-used technology to recognize text inside images. It examines the text of the documents and converts the characters into code that can be used for data processing. Proactive DLP now can utilize this technology to detect and redact sensitive information.

OCR Quality:
Normal: detect the information without pre-processing images
Best: pre-processing images before detecting the image to have a better detection rate, however, performance will be impacted
