摘要: The invention discloses a generation method and apparatus of verification picture belongs to the computer technical field. includes following steps that: an initial containing code is obtained; first region at least part content selected from in picture; noise points are generated on contained region; second other region, namely picture, so that can be obtained. According invention, therefore, machine cannot filter out through simple algorithms, thus, identification difficulty increased, risk cracked by lowered, has strong anti-cracking ability.
