    • When a signature is registered, a signature in Japanese characters, for example, ‘’ (‘Fujitsu’), or a signature in English characters, for example, ‘Fujitsu’ is input n times through an input device of an input equipment of a signature authentication system, and each element of the shape of handwriting, writing speed, writing acceleration, and writing pressure is computed. A combination of nC2 is set for each element of the data input n times, the reciprocal of each similarity is obtained, an average value of the similarity is computed for each element, a weight is determined for each similarity from the average value, a weighted average value of the four elements is computed and defined as the total similarity of the registered signature. In an authenticating process, signature data to be compared is input/output m times. In the same method, the total similarity of a signature to be compared is obtained.
    • 当签名被注册时,以日文字符的签名,例如'“自定义字符”img-content'('Fujitsu')或英文字符的签名,例如'Fujitsu'通过输入设备输入n次 的签名认证系统的输入设备,并且计算手写形状,写入速度,写入加速度和写入压力的每个元素。 为数据输入的每个元素n次设置nC2的组合,获得每个相似度的倒数,为每个元素计算相似度的平均值,从平均值确定每个相似度的权重,加权 计算四个元素的平均值并将其定义为注册签名的总相似度。 在认证过程中,要比较的签名数据是输入/输出m次。 在相同的方法中,获得要比较的签名的总相似度。
