Abstract

A document, preferably in the form of a lottery ticket has a security system in which a substrate has thereon an encoded game data portion including a base layer printed with an ink having a first reflectance value as measured by the reflectance of a given wavelength of light and a second layer of ink having a second reflectance value together having an encoded pattern of symbols. The encoded game data portion is covered with a scratch-off layer in which improper removal of the scratch-off layer can be detected through either the change in the reflectance pattern of the encoded game data portion or by an alteration in the encoded pattern of symbols.
