1. A system comprising:
one or more processors; and one or more non-transitory computer-readable media storing computer-executable instructions that, when executed, cause the one or more processors to perform operations comprising:
receiving, from a user-recognition system, a request to verify that a first palm depicted in first image data corresponds to a second palm depicted in second image data;
receiving the first image data depicting the first palm;
receiving the second image data depicting the second palm;
identifying, using the first image data, a first characteristic exhibited in a first portion of the first palm, the first portion being less than an entirety of the first palm;
extracting, from the first image data, first feature data representing the first characteristic exhibited in the first palm;
extracting, from the second image data, second feature data representing the first characteristic exhibited in the second palm;
analyzing, by the system, the first feature data with reference to the second feature data;
calculating, based at least in part on the analyzing the first feature data, a first similarity score representing a measure of similarity between the first characteristic exhibited in the first palm and the first characteristic exhibited in the second palm;
identifying, using the first image data, a second characteristic exhibited in a second portion of the first palm, the second portion being less than an entirety of the first palm;
extracting, from the first image data, third feature data representing the second characteristic exhibited in the first palm;
extracting, from the second image data, fourth feature data representing the second characteristic exhibited in the second palm;
analyzing, by the system, the third feature data with reference to the fourth feature data;
calculating, based at least in part on the analyzing the third feature data, a second similarity score representing a measure of similarity between the second characteristic exhibited in the first palm and the second characteristic exhibited in the second palm;
verifying, based at least in part on the first similarity score and the second similarity score, that the first palm corresponds to the second palm; and
sending, to the user-recognition system, output data verifying that the first palm corresponds to the second palm.
