During operation a biometric identification system acquires an image of at least a portion of a user that is processed by a representation model to determine representation data. The representation data may be securely stored for later use. The image is not stored. The stored representation data is smaller than equivalent image data. The representation model may comprise a subset of a first recognition model that has been trained using image training data. The image training data may be processed by the trained representation model to determine training representation data. The representation data contains sufficient information to be used as training data for recognition models, instead of acquired images. Training of recognition models using representation data is more computationally efficient compared to training with image data. Recognition comparisons using query representation data are more computationally efficient compared to query image data.
