New 'Semantic Overlays' Technique Enhances LLM Security Against Prompt Injection

Researchers have developed a new technique called Semantic Overlays to combat prompt injection attacks in language models. This method introduces a non-textual channel to the model's input, allowing it to understand the identity of text spans beyond just their token representation. By applying learned adapters to the model's residual stream, Semantic Overlays can encode complex semantics, such as marking a span as non-executable, which significantly reduces the success rate of various prompt injection attacks while maintaining the readability and utility of the original content.
