随着时代不断地发展，计算机技术迅速地更新，为了人们的信息安全，验证码技术已经成为保护网络安全的重要手段。验证码技术属于人机区对于大小固定的、质心位置居中的验证码，可以得到百分之百的识别率。由于扭曲字符干扰较大，所以识别率达不到理想效果。文章采用的方法有助于提高验证码的安全性。

With the development of times constantly, computer technology quickly updates. In order to protect people's information security, the verification code technology has become an important means of protecting the security of network. The verification code technology is used to distinguish between computers and humans, so hacker's attack could be prevented efficiently. This article analyzes the working principle of verification code, by use of projection of the N* N template segmentation, Euclidean distance method is also used to identify the verification code. For a fixed size, the centroid position of the verification code, this method can reach to one hundred percent recognition rate. Because the distortion character has larger interference, so the method can't achieve a good recognition rate. This article uses the method is helpful to improve the safety verification code.
