Issue/Introduction

You have successfully implemented Optical Character Recognition (OCR) in your DLP environment

However in the Enforce console, you notice a significant number of alerts with the code 4803 - OCR Request was not successful

Clicking on the details of the alerts shows the subcatagory: Image Size Error

Eg. Error while loading page: Image error: [8004c70e]: IMG_SIZE_ERR - *2363063181216,3924 (0)

Cause

These alerts are because the OCR pre-filter on the detection server is mistakenly passing images to the OCR servers that are of incorrect size and are unsuitable for OCR extraction.

The OCR server then drops that file and posts the alert to the Enforce

Environment

Release : 15.x

Component : OCR

Resolution

Alerts of this type can be safely ignored, no extractable data was available in those images in the first place, so OCR detection is not failing.
