I added a new way for the app to detect personal information by using named entity recognition. Previously, the app could only find structured information like emails and phone numbers, but it could not detect things like names. So I integrated Presidio to identify such information from the text extracted from images. These extractions are then combined with the existing PII detections done using regex for the structured stuff. This improves the accuracy of the entire system by combining multiple detection methods instead of relying on one single approach.
Next, I will improve the detection process further as right now it isn’t too accurate, mostly because I think the OCR is missing some stuff from the text. So I might try replacing it or find some other way.
