ResultsEnd-to-end architecture for cross-modal prompt injection detection, from multi-modal input ingestion through explainable output generation.
A curated cross-modal benchmark for evaluating prompt injection detection across diverse vision-language scenarios.
The Prism dataset comprises 125,000 image-text pairs spanning 12 distinct attack categories, including typographic overlay injection, semantic prompt manipulation, and adversarial perturbations targeting vision-language model pipelines. Samples are sourced from publicly available VQA benchmarks, synthetically generated attack scenarios, and real-world adversarial examples collected through red-teaming exercises. Each sample is annotated with ground-truth labels, attack type metadata, and confidence calibration scores.

Modular, production-ready Python codebase powering the cross-modal prompt injection detection pipeline. Built with FastAPI, PyTorch, and clean architectural patterns.
End-to-end training workflow for the cross-modal prompt injection detection system, from raw data preprocessing through model evaluation and deployment readiness.
Raw image-text pairs undergo normalization, tokenization, and augmentation. Vision inputs are resized and transformed, while text prompts are cleaned and embedded. Adversarial samples are injected to strengthen robustness during training.
Pre-trained vision encoders (ViT/CLIP) extract spatial features from images while transformer-based language models encode textual semantics. Cross-modal alignment layers fuse both modalities into a shared embedding space.
The detection model is trained using a multi-task loss combining binary injection classification, confidence calibration, and contrastive alignment. Gradient accumulation and mixed-precision training accelerate convergence on multi-GPU setups.
Trained checkpoints are evaluated against held-out test sets and adversarial benchmarks. Metrics including accuracy, F1 score, precision, recall, and AUC-ROC are computed. Explainability heatmaps validate model attention alignment.
We present Prism-Dashboard, a comprehensive cross-modal prompt injection detection framework designed for Vision-Language Models (VLMs). As VLMs become increasingly deployed in security-sensitive applications, the risk of adversarial prompt injection attacks that exploit the interplay between visual and textual modalities has grown significantly. Our framework introduces a modular seven-stage pipeline encompassing input processing, multi-modal feature extraction, attention-guided fusion, ensemble detection, and gradient-based explainability. We evaluate on 12 benchmark datasets spanning text-image, text-video, and text-document modalities, demonstrating a 96.3% detection accuracy while maintaining sub-45ms inference latency. Through adversarial training with novel gradient perturbation strategies, we achieve a 22% improvement in robustness against adaptive attacks. The accompanying dashboard provides researchers and practitioners with real-time visualization, interactive heatmaps, and publication-ready analytics for understanding model behavior under adversarial conditions.
