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.
Claims15
An authenticity verification apparatus comprising;
- a lens including at least a first section and a second section, each said section containing distinct lenticular parameters,
- said first section being constructed and arranged for decoding a first encoded latent image;
- said second section being constructed and arranged for decoding a second encoded latent image;
- whereby the authenticity of an object containing plural latent images, each defined by a distinct set of lenticular parameters, may be verified.
A method for authenticating an object containing encoded images comprising;
- selecting at least first set of distinct lenticular parameters;
- selecting at least a second set of distinct lenticular parameters;
- creating a multi-section decoding lens by incorporating said at least first set of parameters within a first section of said lens and incorporating said at least second set of parameters within a second section of said;
- inputting each said set of parameters into a software program;
- encoding, via said software program, at least a first latent image as a function of said parameters of said first lens section;
- encoding, via said software program, at least a second latent image as a function of said parameters of said second lens section;
- rastorizing, via said software program, a source image;
- combining, via said software program, said at least first and said second encoded latent images with said rasterized source image;
- encoding an object by imprinting said latent images within said source image onto said object;
- and
- verifying authenticity of said object by decoding said at least first and said second latent images with said multi-section decoding lens.
