Optical encryption structure which allows for creating shapes on a surface that cannot be detected with eyes or cameras and revealing these created shapes with a key, the structure comprising the following: the following; an encryption layer consisting of a dielectric layer hiding the information wherein the information consists of the shape desired to be hidden is processed and a metal layer used to create Fabry-Perot, plasmonic or powerful interference effects, • a decryption layer which enables visualizing the hidden information, is located on the encryption layer in order to visualize the hidden information, consists of a transparent substrate which enables the required mechanical support to dielectric, semi-conductive films and an absorber layer which enable creating Fabry-Perot, plasmonic or powerful interference effects wherein, the encryption and the decryption layer that have key and lock integrity between them and the dielectric layer having thicknesses sections which is t1 and t2 that are different from each other and varies the spectrum of the reflecting or transmitting light, the differences in the dielectric thickness are selected to enable visualization of the shapes in a manner such that it is perceivable with eyes when only the decryption layer is present in such a way that the encryption and the decryption layers are positioned to provide key and lock integrity between them. the following; an encryption layer consisting of a dielectric layer hiding the information wherein the information consists of the shape desired to be hidden is processed and a metal layer used to create Fabry-Perot, plasmonic or powerful interference effects, • a decryption layer which enables visualizing the hidden information, is located on the encryption layer in order to visualize the hidden information, consists of a transparent substrate which enables the required mechanical support to dielectric, semi-conductive films and an absorber layer which enable creating Fabry-Perot, plasmonic or powerful interference effects wherein, the encryption and the decryption layer that have key and lock integrity between them and the dielectric layer having thicknesses sections which is t1 and t2 that are different from each other and varies the spectrum of the reflecting or transmitting light, • a decryption layer which enables visualizing the hidden information, is located on the encryption layer in order to visualize the hidden information, consists of a transparent substrate which enables the required mechanical support to dielectric, semi-conductive films and an absorber layer which enable creating Fabry-Perot, plasmonic or powerful interference effects wherein, the encryption and the decryption layer that have key and lock integrity between them and the dielectric layer having thicknesses sections which is t1 and t2 that are different from each other and varies the spectrum of the reflecting or transmitting light, the differences in the dielectric thickness are selected to enable visualization of the shapes in a manner such that it is perceivable with eyes when only the decryption layer is present in such a way that the encryption and the decryption layers are positioned to provide key and lock integrity between them. <EOS>
