    • An authenticable optical disc and a system and method for authenticating the optical disc are provided. The optical disc comprising a reflective layer; an optically transparent substrate disposed between the reflective layer and a light incident surface of the optical disc; a data layer disposed between the substrate and the reflective layer, the data layer including a predetermined signature; and at least one measurable feature, wherein the at least one feature is compared to the predetermined signature for authenticating the optical disc. The method comprises the steps of preparing an optical disc with at least one optical feature; measuring intensity of transmitted light from the at least one optical feature; and comparing the measured intensity to a predetermined signature, wherein if the measured intensity and predetermined signature matches, access to the optical disc is granted.
    • 提供了一种认证光盘和用于认证光盘的系统和方法。 该光盘包括反射层; 设置在所述反射层和所述光盘的光入射表面之间的光学透明基板; 设置在所述基板和所述反射层之间的数据层,所述数据层包括预定的签名; 以及至少一个可测量特征,其中将所述至少一个特征与用于认证所述光盘的所述预定签名进行比较。 该方法包括准备具有至少一个光学特征的光盘的步骤; 测量来自所述至少一个光学特征的透射光的强度; 以及将测量的强度与预定签名进行比较,其中如果所测量的强度和预定签名匹配,则允许对光盘的访问。
