摘要: Systems and methods to tell apart computers humans using image recognition task having a dynamic graphical arrangement of randomly selected images. The images can be arranged as grid or matrix for presentation on device display authentication user human. kinds derived from category the task. A series generated access codes corresponding displayed with may enter category. An server compare code entry an reference particular selection images, their codes, dynamically change in between verification sessions.
