Abstract: A method is presented for decoding an encoded image produced from a primary image and at least one secondary image using at least one encoding parameter. The encoded image is formed so that when the encoded image is printed, the secondary image is not discernible to a viewer without an optical decoding device having characteristics corresponding to the at least one encoding parameter. The method comprises obtaining a digital version of the encoded image, determining the at least one encoding parameter, and constructing a decoded image from the digital encoded image using at least one of the encoding parameters in the encoding parameter set.

Abstract: A reflective decoding device is provided for use in decoding an encoded image comprising a latent image encoded using at least one encoding parameter.

The predetermined pattern is configured with at least one geometric characteristic corresponding to the at least one encoding parameter so that placement of a light-transmissive sheet having the encoded image formed thereon over the predetermined pattern of topographical features allows the latent image to be viewed.

Abstract: A method is provided for determining whether a test object is an authentic object having an authentication image applied to an authentication image area thereof. The method comprises positioning and orienting a portable image acquisition device for selectively viewing and capturing a magnified image of a target surface area of the test object. The target surface area corresponds to the authentication image area of an authentic object. The method further comprises capturing a magnified digital image of the target surface area using the image capture acquisition device. The captured digital image is then processed to obtain a processed digital image and an authentication result is determined based on whether the processed digital image meets predetermined authentication criteria.

The request includes user-supplied data for producing the encoded image, the user-supplied data including user-supplied authentication indicia and/or at least one user-supplied encoding parameter. The method further comprises determining whether the user is authorized to produce an encoded image using the user-supplied data. Responsive to a determination that the user is authorized to produce an encoded image using the user-supplied data, encoding actions are carried out. The encoding actions include establishing at least one digitized authentication image and establishing an encoding parameter set including any user-supplied encoding parameters. The encoding parameter set is usable to encode one or more of the at least one digitized authentication image.

The method comprises attaching a digital data storage medium to the object and storing an optically decodable digital encoded image in the data storage medium. The digital encoded image comprises authentication information determinable by decoding the digital encoded image. The method further comprises downloading the digital encoded image from the digital data storage medium and applying a digital decoding algorithm to the captured digital image to establish a decoding result. The decoding result is then compared to object authentication criteria to establish an authentication result.

The method comprises receiving from a user data processor a request for authorization to produce an encoded image. The authorization request includes user-supplied data comprising at least one authentication image file.

Responsive to a determination that the user is authorized to produce an encoded image using the user-supplied data, an authentication image signature is generated from the at least one authentication image file using an image signature algorithm and a positive authorization response is returned to the user data processor. The positive authorization response includes the authentication image signature.

The system also includes a central authentication system in communication with the imaging device to receive optical images recorded by the imaging device.

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.

Positioning is achieved so that the line elements are disposed substantially parallel to the lines in the lineticular dissection.
