CaMeL offers a promising new direction for mitigating prompt injection attacks
Google DeepMind's CaMeL system aims to mitigate prompt injection attacks in LLMs by converting user commands into secure steps, enhancing AI security through robust design while requiring user-defined security policies.

A new paper from Google DeepMind introduces CaMeL (Capabilities for Machine Learning), a system designed to mitigate prompt injection attacks, which have posed significant security challenges for LLM-driven assistants. Prompt injection occurs when untrusted text is combined with trusted user prompts, leading to potential misuse, such as unauthorized data access. CaMeL addresses this by converting user commands into a sequence of steps using a restricted Python-like programming language, ensuring that data is only passed to trusted locations. This system builds on the Dual LLM pattern, which separates the processing of trusted and untrusted data through two distinct LLMs. While CaMeL significantly enhances security by implementing capabilities and data flow analysis, it is not a complete solution, as it requires users to define and manage security policies, which can lead to user fatigue. Despite these limitations, CaMeL represents a promising advancement in the field of AI security, moving away from reliance on additional AI for protection and instead focusing on robust system design principles.
