Abstract
A label for concealing proprietary information is attached to a backing material and includes a layer of adhesive, a base layer, an opaque scratch layer, which can be removed by rubbing, and an authentication mark applied to the scratch layer. The information may be on the backing material or between the base and scratch layers. In another embodiment, an ink film is located between the base layer and an object. Areas of anti-stick lacquer are provided between the ink film and the object, so that the relative adhesive force on the ink film has spatial variations.
