Abstract
The present invention is a multi-section lens for decoding at least two encodings, as a function of the parameters of a lens section, of at least one latent image, 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 is a function of distinct lenticular parameters which may include the frequency and lens radius of curvature of a particular lens section. Each section has a corresponding encoded latent image thus allowing for multiple latent images and multiple encodings making it virtually impossible to counterfeit the encoded object or the decoding apparatus.
