Overlay human interactive proof system and techniques

摘要: The overlay human interactive proof system (“OHIPS”) and techniques described herein operate in conjunction with any known or later developed computer-based applications services to provide secure access resources by reliably differentiating between non-human users. Humans have a generally superior ability differentiate misaligned characters objects from correctly aligned ones. As such, the OHIP splits an image including one more visual into two partial images form HIP. may also be further split groups of sub-partial images, and/or (or images) moved, so that at given alignment position, user can recognize only some objects. A is instructed reassemble predetermined positions using GUI, asked identify information regarding visible
