Abstract
A method, apparatus and system for rendering a security mark, can involve providing two variable layers of data text for a security mark including a first variable layer and a second variable layer, and applying the security mark to a recording medium using the two variable layers to create a third variable layer of the security mark. The second variable layer can be applied out of phase or orthogonally from the first variable layer at the same frequency, which can form the third variable layer with data text that is decodable. The third variable layer with the data text can be decodable with a decoding screen. In addition, the first, second, and third variable layers can share the same area. The security mark may comprise a correlation mark.
