Claim 0:
1. A method in which one or more processing devices of an authentication server system perform operations comprising:
servicing an authentication query by matching an unstructured input data object included as a query parameter in the authentication query to an unstructured reference data object stored in a memory device of the authentication server system, wherein matching the unstructured input data object to the unstructured reference data object comprises:
providing the unstructured input data object to a dual deep learning network having an embedding subnetwork and a relationship subnetwork, wherein outputs from an output layer of the embedding subnetwork are provided as inputs to the relationship subnetwork via an input layer of the relationship subnetwork, wherein the dual deep learning network is configured for:
generating, via the embedding subnetwork, an input feature vector from the unstructured input data object, wherein the embedding subnetwork is trained to generate training feature vectors from unstructured training data objects, and
providing, from the output layer of the embedding subnetwork to the input layer of the relationship subnetwork, the input feature vector and a reference feature vector, wherein the relationship subnetwork is trained, with relationship training feature vectors generated by the embedding subnetwork, to output probabilities of pairs of the relationship training feature vectors belonging to common classes, and

obtaining, from the dual deep learning network, an output probability of the unstructured input data object and the unstructured reference data object belonging to a common class, the output probability generated by the dual deep learning network applying the relationship subnetwork to the input feature vector and the reference feature vector; and
transmitting, to a client computing system, a responsive message to the authentication query that is generated from the output probability, wherein the responsive message is configured for causing the client computing system to grant or deny access to the client computing system by a user device from which the unstructured input data object was obtained.
