Ever worried that your Personal Identifiable Information such as your name, credit card number etc is exposed in personal documents, images or videos?
With the help of AWS AI services, we will see how to safeguard your personal information.
As you might all be aware that the PII Detection is already available for text documents using Amazon Comprehend, I have extended this feature for images and videos as well using Amazon Rekognition. The possible PII Information that can be detected are listed over here.
The PII is identified and redacted using Amazon Comprehend PII Detection API.
First, the text presented in the image is detected using Amazon Rekognition Text Detection API. Information such as text, their bounding box and relevant details are obtained from the API.
The text is prepared as a document and passed to the Amazon Comprehend PPI Detection API where all PII available in the text is concatenated. Then the relevant PII text in the image is blurred using Rekognition and OpenCV.
The same above technique is performed for every frame of the video.
