Abstract: Systems and methods are directed to authenticating items using object fingerprinting and deep learning. A system extracts visual features from an image of the item to be authenticated. Using the visual features, the system performs prefiltering by comparing the visual features from the image of the item to visual features of an image of an authentic item that is same or similar to the item. Based on the prefiltering analysis indicating that the visual features from the image of the item matches the visual features from the image of the authentic item, deep learning analysis is performed by applying the image of the item and at least two other images including the image of the authentic item to a convolutional Siamese neural network (SNN). The convolutional SNN generates image embeddings used to derive similarity scores. Based on the similarity scores, a determination is made whether the item is authentic.
