User authentication

摘要

An apparatus lets a user to determine a pool of images and then forms from the pool of images a set of images for user authentication and divides the set of images into two mutually exclusive subsets: a key image subset comprising images referred to as key images and a decoy image subset comprising images referred to as decoy images. The apparatus displays the key images to the user to teach the key images to the user. Then, to authenticate the user, the apparatus produces an assortment of decoy images and key images, and displays the assortment to the user. The apparatus receives from the user identification of images held as key images and verifies whether the identification of key images matched with the key images selected by the processor.

1. An apparatus comprising:
a processor and a memory including computer program code, the memory and the computer program code configured to, with the processor, cause an apparatus to: receive a user-defined pool of images; form only from the user-defined pool of images a set of user-pooled images for user authentication; divide the set of user-pooled images into two mutually exclusive subsets: a key user-pooled image subset comprising user-pooled images referred to as key user-pooled images and a decoy user-pooled image subset comprising images referred to as decoy user-pooled images; perform user-education regarding said key user-pooled image subset resulting from said division and regarding said decoy user-pooled image subset resulting from said division, wherein there is display regarding the key user-pooled image subset resulting from said division and regarding the decoy user-pooled image subset resulting from said division; produce an assortment of decoy user-pooled images and key user-pooled images; cause displaying the assortment of decoy user-pooled images and key user-pooled images; cause receiving user identification of user-pooled images held as key user-pooled images; and verify whether the identification of key user-pooled images matched with the key user-pooled images selected by the processor.
