Abstract
In an embodiment, a method includes receiving a prompt provided to a large language model (LLM), generating a semantic fingerprint for the prompt based on semantic and syntactic features associated with the prompt, generating a vector representation incorporating the semantic fingerprint for the prompt, calculating semantic distances between the vector representation and multiple vector representations associated with multiple malicious intents, determining an intent associated with the prompt based on the semantic distances, and determining a defense action on the prompt based on the intent and multiple policies to mitigate a security risk associated with the prompt.
