How and why are my image files altered during processing with Deep CDR and Proactive DLP?

To process image files, the Deep CDR engine engages the following process:

1. The image file is decompressed in order to access and process the raw data.
2. The engine then reconstructs a safe-to-use file by processing the pixels from the image.
3. During content disarming and reconstruction, potential steganography (data concealment) is treated by adding noisy data to ‘break’ hidden elements, while unnecessary data is discarded.
4. In the final stage of reconstruction, the file is compressed with the same image encoding as the original file.

To process image files, the Proactive DLP engine engages the following process:

1. The image file is decompressed in order to access and process the raw data.
2. The decompressed file is systematically scanned for sensitive and possibly confidential information.
3. This information, if any, is redacted or removed.
4. In the final stage of reconstruction, the file is compressed with the same image encoding as the original file.
