EURion constellation

非常有趣的东东,这是在各国钞票上做的一个类似星座的标记,这个标记使得软件可以在一幅图像中检测出是否存在钞票,如果存在,软件将拒绝对其编辑而避免伪造钞票。参见Wikipedia的解释:

The EURion constellation is a pattern of symbols found on a number of banknote designs since about 1996. It is added to help software detect the presence of a banknote in a digital image. Such software can then block the user from reproducing banknotes to prevent counterfeiting using colour photocopiers.

这个标记大约是这个样子的:

支持这个系统的国家非常多,中国的2004年的一元纸币、2005年的5元纸币及以后的所有版本人民币都支持。
支持这个系统的软件包括著名的adobe photoshop,因此,photoshop是无法是PS新版人民币图像的?有时间测试一下……
