Concern 35 · Working draft · editorial review in progress
Steganographic poisoning
Steganographic poisoning hides a malicious training signal inside content that appears ordinary to a human reviewer.
Understanding the concern
Steganography means concealing a signal within other material. In AI, a subtle visual or other pattern may serve as a hidden cue. This is a concealment technique, not a separate guarantee that an attack will work.
The original entry grouped images, audio, and documents together. Evidence depends on the particular format and system, so one demonstration should not be generalized to all of them. A readable preview may reveal less than the full data a model processes.
An example
A watermark too subtle for a quick glance could still be a pattern a machine repeatedly notices.
Illustrative unless identified as a documented case.
Words in plain English
- AI
- Software that learns patterns from examples or uses rules to perform tasks such as recognizing images or generating text. It can make mistakes and does not understand every situation as a person would.
- Model
- The learned part of an AI system. It uses patterns found during training to produce an answer or prediction.
- Training
- The process of using examples to shape how an AI model behaves. Learning patterns from material does not establish that the material is true or fair.
- Data poisoning
- Deliberately changing training material to push a system toward unwanted behavior.
Evidence and its limits
NIST describes backdoor and input-manipulation mechanisms; format-specific effectiveness requires additional evidence.

Virtues and principles to consider
Virtues are qualities we practice in how we treat people and make choices. They are not scores for judging someone. Use these ideas to explore what a thoughtful response could look like.
Truthfulness
Truthfulness means making claims that match the evidence and being clear about what we do not know. It includes correcting mistakes rather than protecting a polished story.
Check sources, label guesses, and distinguish a trial result from a proven benefit. If AI helped produce a claim, someone still needs to take responsibility for checking it.
Ask together: What can we honestly say, and what still needs checking?
Justice
Justice means fair treatment, fair procedures, and attention to who receives benefits and burdens. It asks whether people with less power can be heard and seek repair.
Look at outcomes across different groups and individual cases. Provide a usable way to challenge decisions and correct harm. Equal wording in a policy does not guarantee equal treatment in practice.
Ask together: Who benefits, who bears the cost, and who can challenge the decision?
Stewardship
Stewardship means caring for resources and systems that others depend on, including people who will use them later. It looks beyond the benefit of a quick launch.
Plan for maintenance, energy use, data protection, and eventual shutdown. Ask who will look after the tool when the original team moves on and how future users can avoid inheriting hidden costs.
Ask together: What are we responsible for caring for over time?
