PayShield

Sophisticated fraud rings were submitting doctored identity documents that passed PayShield's existing OCR-plus-rules system. Synthetic IDs combining real and fabricated data evaded detection 28% of the time. Each missed fraud case cost an average of $47,000 in losses for PayShield's clients. The company was also struggling with high false-positive rates (19%), creating friction for legitimate customers.

Mixpeek's multimodal analysis examines identity documents holistically: visual authenticity signals (microprint, hologram reflections, font consistency), document layout conformance, data field cross-validation, and facial embedding comparison against selfie verification. The feature extractors capture signals invisible to OCR-only approaches, like subtle pixel-level manipulation artifacts or inconsistent lighting across document regions.

PayShield integrated Mixpeek's inference API into their verification pipeline as a secondary analysis layer. Documents flagged by the initial check are routed to Mixpeek for deep multimodal analysis. The system processes each document in under 800ms, well within PayShield's 3-second SLA. Training data from confirmed fraud cases is used to continuously improve detection models through a feedback collection.
