Application: Multimodal biometric fusion based authentication (Patent ID: US20230401302A1)
The patent filed by Thales SA describes a method for recognizing individuals by combining match results from different biometric recognition systems into a fused match result using a fusion model. The method involves training the fusion model with retrieved data to optimize parameters for achieving a target performance metric. The fusion model is then updated with the optimized parameters in a database and applied to match results to recognize the individual. Various embodiments are disclosed, including scenarios where the match results are matching scores or rank lists, and different models such as a probability-ratio model or a weighted voting model are used for fusion.
The method outlined in the patent involves a multimodal biometric fusion system that includes a training engine and a fusion engine. The training engine receives a training request to optimize fusion model parameters, performs machine learning-based training on retrieved data, and updates the fusion model with optimized parameters in the database. The fusion engine receives a message from a fusion controller containing match results from different biometric modalities, retrieves optimized parameters from the database, and applies the fusion model to calculate a fused match result for individual recognition. The system also includes a computer program with instructions for executing the recognition process. Overall, the patent details a comprehensive method and system for multimodal biometric recognition through fusion of match results from different biometric modalities.
