    • The invention relates to the securing of information media so as to prevent any alteration or modification of the identification information and the fraudulent reuse of the media. The identification document according to the invention comprises personalisation information placed on at least one of its main sides, and invisible anti-forgery means placed on at least part of the said side and designed to undergo a change in appearance in the event of an attempt to do additional personalisation. The anti- forgery means are formed by subdividing each pixel into a matrix of N dots, the said N dots having each a different colour density in order to obtain an average colour density of the said matrix that is equivalent to the colour density predetermined for the corresponding pixel, at least some of the said N dots of the matrix being pre-sensitised so that their colour darkens at a variable speed in the event of additional personalisation, as compared to the other non pre- sensitised dots
    • 本发明涉及信息媒体的保护,以防止对标识信息的任何改变或修改以及媒体的欺诈性重用。 根据本发明的识别文件包括放置在其主要侧面中的至少一个上的个性化信息,以及放置在所述侧面的至少一部分上的不可见的防伪装置,并被设计成在尝试时发生外观改变 做额外的个性化。 防伪手段是通过将每个像素分成N个点的矩阵形成的,所述N个点具有不同的颜色密度,以便获得所述矩阵的平均颜色密度,该平均颜色密度等于为 相应的像素,所述矩阵的所述N个点中的至少一些被预敏化,使得与其它非预感光点相比,在附加个性化的情况下,它们的颜色以可变速度变暗
