KBF: Knowledge Boundary as Fingerprint for Language Model and Black-Box API Auditing

Researchers introduce KBF, a black-box auditing protocol that detects fraudulent LLM API substitutions by analyzing model behavior at knowledge boundaries. Testing across 16 production endpoints revealed all economically relevant model swaps without false positives, and identified inconsistencies in 7 of 27 model cells across major AI platforms, particularly affecting Claude premium endpoints.

BinaryShield: Cross-Service Threat Intelligence in LLM Services using Privacy-Preserving Fingerprints

BinaryShield is the first privacy-preserving threat intelligence system that enables secure sharing of attack fingerprints across compliance boundaries for LLM services. The system addresses the critical security gap where organizations cannot share prompt injection attack intelligence between services due to privacy regulations, achieving an F1-score of 0.94 while providing 38x faster similarity search than dense embeddings.

idSCD: Identifying Training Datasets through Semantic Correlation Descriptors

Researchers have developed a new method called Semantic Correlation Descriptors (SCDs) to identify whether a specific dataset was used to train a machine learning model by analyzing the spurious correlations embedded in its learned structure. This white-box approach outperforms existing black-box membership inference techniques, achieving up to 60% higher accuracy in detecting dataset membership across natural language and medical text classification tasks.

Efficient and Scalable Provenance Tracking for LLM-Generated Code Snippets

Researchers introduce SourceTracker, a 300M-parameter encoder combined with a hybrid two-stage pipeline that uses vector search and fingerprinting to efficiently track code provenance in LLM-generated snippets. The system achieves logarithmic-time query complexity while maintaining high precision on billion-scale datasets, addressing scalability challenges in detecting plagiarism and license violations in AI-generated code.
