A new paper from Israel has proposed an authentication scheme based on a user's aesthetic preferences, wherein the user calibrates the system one time by rating images, thereby generating a private'domain' of that individual's visual and visual/conceptual predilections. Later, the user would be challenged at authentication time to match their recorded preferences against novel image sets. From the trials of a'game-ized' AEbA implementation – left, the user rates the aesthetic quality of an image; right, a score is signaled at the end of a stage in the active application phase of the trials . The system is titled Aesthetic Evaluation-based Authentication (AEbA), and is a submission to the 2022 USENIX Annual Technical Conference in California in July. AEbA was trialed by the paper's researchers in the form of a game series, where participants were required to train the system and then rate new images that accorded with their registered tastes.
