摘　　要：验证码技术是有效防止非人为控制程序的一种防范机制,技术应用领域很广泛。在互动多媒体技术领域中的验证码技术,应通过自带的系统字库生成英文验证码,并对传统的验证码生成技术进行优化改进,采用交错式方法混乱字符增加噪点,经过多次实验该验证码加大了程序系统自动识别难度,从而达到了降低其机器识别率效果。Identifying code is a prevention mechanism which can effectively prevent non-manual control programs and has a wide application area. In the field of interactive multimedia technique, it is supposed to use word library came with the system to create English identifying code, and carries on optimization and improvement on the traditional generating technique. It adopts interlac-ing method to confuse characters and increase noise. After several experiments, the difficulties of automatic recognition of pro-gram systems are increased so that the effect of reducing machine recognition rate is successfully achieved.
