I need to use the aws Rekognition with Galleries so client that use my service can upload his photo and search his photos inside the gallery, like Google Photos. but lets say we have 1000 images inside the gallery and 200 clients enter the service. its like 1000x200 = 200K scans in the worst scenario. My question is if there way to make that the same person will have the same scan results so I can search by results (like same ID or something) and not by scans every time so I can reduce costs because in the regular way in worst scenario I will pay too much and it will be not very nice to my pocket and the service will cost to much for costumers . Thank you
