<p>The present invention is a multi-section lens (14, 16) for decoding at least two encodings, as a function of the parameters of a lens section (12, 18), of at least on latent image (20), as implemented by a software program on a computer system, for security measures such as determining the authenticity of an object. The encoded latent image (20) is a function of distinct lenticular parameters which may include the frequency and lens radius of curvature (12, 18) of a particular lens section. Each section (14, 16) has a corresponding encoded latent image thus allowing for multiple latent images (20) and multiple encodings making it virtually impossible to counterfeit the encoded object (24) or the decoding apparatus.</p> |
