Create or edit an Image Analysis profile

Select Create New to open the Create Image Analysis Profile window.

To open the Edit Image Analysis Profile window, select a profile and then click Edit.

Configure the following settings and then click OK:

Name

Enter a name for this profile.

Comments

Optional description of the profile.

Image Skip Size

Enter a value between 0 and 2,048.

This value represents the image size that will be skipped by the image scan unit, in kilobytes. Images that are too small are difficult to scan and are more likely to be rated incorrectly by the image scan engine.

The default value is 1.

Image Skip Width

This value represents the image width that will be skipped by the image scan unit, in pixels. Images that are too small are difficult to scan and are more likely to be rated incorrectly by the image scan engine.

The default value is 30 pixels; the minimum value is 5 pixels.

Image Skip Height

This value represents the image height that will be skipped by the image scan unit, in pixels. Images that are too small are difficult to scan and are more likely to be rated incorrectly by the image scan engine.

The default value is 30 pixels; the minimum value is 5 pixels.

Rating Error Action

Set to either Pass or Block the image when it exceeds the rating threshold.

The default is Pass.

Replace Image

Select a replacement image in the following formats:

  • JPEG

  • GIF

  • TIFF

  • PNG

Other image types are not supported.

To specify the replacement image, go to System > Replacement Messages and select Manage Images.

Log Option

Select All to log all content or Violation to log content that exceeds any of the strictness levels.

Saving Blocked Images

Enable to save blocked images.

Optical Character Recognition

Enable or disable optical character recognition which detects and extracts text in images with a score greater than the configured OCR threshold and takes action accordingly as defined in the DLP profile.

Note

This option takes effect only if the policy meets the following requirements:

  • Content Analysis is enabled with this image analysis profile selected.

  • DLP Profile is enabled with a profile configured and selected.

OCR Activation Threshold

When Optical Character Recognition is enabled, configure the threshold to activate optical character recognition. The value range is 0 - 100, where 0 means bypassing all images without DLP and 100 means processing all images with DLP that triggers OCR. The default is 30.

Block Strictness Level

For each category, select to Allow, Deny, or Monitor content that exceeds the strictness level, and set the level between 0 and 100.

The higher the image score, the more chance of the image being explicit. The challenge with this setting is that if you set it too high, it will block legitimate images. If you set it too low, it will allow explicit images through. If the image score is above this setting, the Rating Error Action is taken.

The default value is 30.

Alcohol

The alcohol category is designed to identify images containing alcoholic brands and beverages, people drinking alcohol, frat parties, keg stands, bars and nightclubs, party aftermaths, shots, beer pong, kegs, and plastic cups associated with drinking.

Drugs

The drugs category is designed to identify images containing illegal and legal drugs, drug use, drug paraphernalia, and plants and symbols relating to drugs.

Extremism

The extremism category is designed to identify images containing terrorist militants, beheadings, executions, propaganda, acts of terrorism, KKK rallies, Hitler, insignia related to Nazism, KKK, ISIS, and white supremacy icons.

Gambling

The gambling category is designed to identify images containing gambling.

Gore

The gore or graphic violence category is designed to identify images containing gore, graphic violence, self-harm, suicide, horrific imagery, bloody wounds, accident victims, shooting victims, beatings, mutilation, decapitation, and images that contain blood and guts.

Porn

The pornography category is designed to identify images and videos containing commercial pornography, amateur pornography, sexting selfies, nudity, sex acts, grayscale pornographic images, sexually explicit cartoons, and manga.

Swim Underwear

The swim and underwear, or risqué, category is designed to identify images containing people wearing swimwear or beachwear, underwear, and lingerie.

Weapons

The weapons category is designed to identify images containing rifles, machine guns, handguns, grenade launchers, swords, knives, and people holding handheld weapons.

Alternatively, use the config image-analyzer profile command to configure an image analysis profile in the CLI.
