Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Artificial intelligence models, particularly large language models, are vulnerable to prompt injection attacks that manipulate their behavior for malicious purposes, leading to unreliable outputs and potential security breaches.
Innovation Solution
A prompt injection classifier is trained using a dataset populated with benign and malicious content in predefined structures to identify and categorize malicious prompts, allowing for remediation actions such as blocking or modifying inputs to prevent undesired model behavior.

Engineering Contradiction Analysis
1Reliability
If a prompt injection classifier is trained to identify malicious prompts, then the security and reliability of AI models is improved, but the complexity of the system increases due to the need for additional training data generation and classification infrastructure
Solution Approach 1:
A prompt injection classifier is introduced as an intermediary component between the user input and the AI model. This classifier analyzes prompts before they reach the main AI model, identifying and blocking malicious inputs. The classifier acts as a mediator that filters harmful content while allowing legitimate requests to pass through to the AI system.
Solution Approach 2:
The system performs preliminary analysis of prompts before they are processed by the AI model. By pre-processing inputs through the classifier and generating embeddings in advance, the system identifies potential threats early in the workflow, preventing malicious prompts from reaching the vulnerable AI model and allowing for preventive security measures.
2Measurement precision
If malicious content is generated using misaligned or jailbroken large language models, then the training dataset comprehensiveness is improved, but the ethical and safety risks increase
Solution Approach 1:
The system converts potentially harmful misaligned or jailbroken language models into beneficial tools for security training. By using these models to generate malicious prompts in a controlled environment, the system creates comprehensive training datasets that improve the classifier's ability to detect real threats, transforming a security risk into a security solution.
Solution Approach 2:
The system takes preliminary anti-action by using misaligned models to generate malicious content before deployment. This pre-generated malicious content is used to train the classifier, creating a prepared defense mechanism that can recognize and counteract similar attack patterns before they reach the production AI model.
3Measurement precision
If prompts are vectorized and embeddings are generated for classification, then the classification accuracy is improved, but the computational resources and processing time increase
Solution Approach 1:
The system changes the parameter representation of prompts by converting text inputs into vector embeddings. This transformation converts discrete text data into continuous numerical representations that capture semantic meaning, enabling more accurate classification while optimizing the data format for efficient processing by machine learning models.
Data Source
AI summary
An analysis engine receives data characterizing a prompt for ingestion by a generative artificial intelligence (GenAI) model. The analysis engine, using a prompt injection classifier determines whether the prompt comprises or is indicative of malicious content or otherwise elicits malicious actions. The prompt injection classifier can be trained using a dataset generated by populating benign content and malicious content into a plurality of different prompt attack structures at pre-defined locations. Data characterizing the determination is provided to a consuming application or process. Related apparatus, systems, techniques and articles are also described.
