摘要： A character code conversion device (10) utilizes not a standard character code table but a conversion character code table that is the converted standard character code, and transmits a conversion character code string indicating a sentence subjected to transmission to a sentence recognition device (20) via a network (N). Hence, even if a third party obtains the conversion character code string, the standard character code table is utilized, and thus the character string specified from the conversion character code string is completely different from the sentence subjected to transmission. Accordingly, proper recognition of the sentence subjected to transmission is difficult. Consequently, the security of the sentence subjected to transmission is enhanced.
摘要翻译：字符代码转换装置（10）不使用标准字符代码表，而是使用作为转换的标准字符代码的转换字符代码表，并且将表示发送的句子的转换字符代码串发送到句子识别装置（20）通过网络（N）。因此，即使第三方获得转换字符代码串，也使用标准字符代码表，因此从转换字符代码串指定的字符串与经过传输的句子完全不同。因此，对发送的句子的适当识别是困难的。因此，增加了传输语句的安全性。

摘要： A two-dimensional code authenticating device reads a self-authentication two-dimensional code to obtain an RS bit string, and detects a bit string c' as an error using the RS bit string. Next, an exclusive OR between a bit string 1 included in the RS bit string and the bit string c' detected as an error is calculated to obtain a bit string c', and a bit string md is obtained by decrypting the bit string c' through a scheme corresponding to the encryption. Subsequently, it is determined whether or not the decrypted bit string md matches the bit string m included in the RS bit string, thereby authenticating the self-authentication two-dimensional code.

摘要： A two-dimensional code display system (1) has a display unit (4) which can display a two-dimensional code representing predetermined information by plural cells arrange in a matrix, and a control unit (2) which changes the display form of the two-dimensional code. For example, after 0.5 second has elapsed since the display unit (4) starts displaying the image of a logo mark, the control unit (2) controls the display unit (4) to change the display from the image of the logo mark to a two-dimensional code. After 2.0 seconds has elapsed since the display unit (4) starts displaying the two-dimensional code, the control unit (2) controls the display unit (4) to change the display from the two-dimensional code to the image of the logo mark. By repeating such control, the control unit (2) can control the display unit (4) to display alternately the image of the logo mark and the two-dimensional code.
摘要翻译：一种二维码显示系统（1）具有：显示单元（4），其能够通过排列成矩阵的多个单元来显示表示预定信息的二维码;以及控制单元（2），其改变二维码。例如，在显示单元（4）开始显示徽标标记的图像之后经过了0.5秒之后，控制单元（2）控制显示单元（4）将显示从徽标标记的图像改变为二维码。从显示单元（4）开始显示二维码开始经过2.0秒之后，控制单元（2）控制显示单元（4）将显示从二维码改变为标志标记的图像。通过重复这种控制，控制单元（2）可以控制显示单元（4）交替地显示徽标标记和二维码的图像。
