## Watermarking
InvokeAI does not apply watermarking to images by default. However,
many computer scientists working in the field of generative AI worry
that a flood of computer-generated imagery will contaminate the image
data sets needed to train future generations of generative models.
InvokeAI offers an optional watermarking mode that writes a small bit
of text, **InvokeAI**, into each image that it generates using an
"invisible" watermarking library that spreads the information
throughout the image in a way that is not perceptible to the human
eye. If you are planning to share your generated images on
internet-accessible services, we encourage you to activate the
invisible watermark mode in order to help preserve the digital image
environment.
The downside of watermarking is that it increases the size of the
image moderately, and has been reported by some individuals to degrade
image quality. Your mileage may vary.
To read the watermark in an image, activate the InvokeAI virtual
environment (called the "developer's console" in the launcher) and run
the command:
```
invisible-watermark -a decode -t bytes -m dwtDct -l 64 /path/to/image.png
```

For these reasons Stable Diffusion offers a "safety checker," a
machine learning model trained to recognize potentially disturbing
imagery. When a potentially NSFW image is detected, the checker will
blur the image and paste a warning icon on top. The checker can be
turned on and off on the command line using `--nsfw_checker` and
`--no-nsfw_checker`.
At installation time, InvokeAI will ask whether the checker should be
activated by default (neither argument given on the command line). The
response is stored in the InvokeAI initialization file
(`invokeai.yaml` in the InvokeAI root directory). You can change the
default at any time by opening this file in a text editor and
changing the line `nsfw_checker:` from true to false or vice-versa:

### Watermarking
InvokeAI does not apply any sort of watermark to images it
generates. However, it does write metadata into the PNG data area,
including the prompt used to generate the image and relevant parameter
settings. These fields can be examined using the `sd-metadata.py`
script that comes with the InvokeAI package.
