Image Policy Settings

[Policy] > [Basic Decontamination Policy] > [Image] Settings​

The image tab sets policies that allow you to balance security and image quality preservation when processing the de-identification of image files.
You can choose the level of steganography removal to determine the priority between security enhancement and preservation of original image quality.

⚠️ The permission to set the basic de-identification policy is granted to [Administrator Type - System Administrator], and
Administrator permission settings can be configured in [Administrator Settings] > [Account and Permission Management].
