Abstract: Systems, methods and apparatuses to perform self-authentication are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, to perform authentication using a tag. The method can further include retrieving a unique identifier from the tag. A second unique identifier is used to determine lighting parameters to be used by the mobile device to illuminate the tag. The method can include, illuminating the tag using the lighting parameters determined and capturing an image generated from the tag in response to illumination of the tag using the lighting parameters. A mathematical representation derived from the image can then use used to generate a hashing function used in authentication.

Abstract: Methods create images viewable under different selected angles on optical storage devices and other photosensitive surfaces and optical storage devices with super-imposed images. Generally, a photosensitive surface is exposed with multiple diffraction patterns creating super-imposed images. These diffraction patterns create super-imposed images on the photosensitive surfaces, which can be read by either a human or a computer.

Abstract: The present invention is directed to methods for creating pseudo-holographic images viewable under different selected angles on optical storage devices and other photosensitive surfaces. The present invention also discloses novel optical storage devices with super-imposed pseudo-holographic images. Generally, a photosensitive surface is exposed with multiple diffraction patterns creating super-imposed pseudo-holographic images. These diffraction patterns create super-imposed images on the photosensitive surfaces, which can be read by either a human or a computer.

Abstract: A laser beam recording system for exposing a photoresist master disc having a photoresist layer formed over a substrate for making a hybrid optical recording disc having a read only (ROM) portion and a writable portion, including a first optical modulator for modulating an intensity of a first laser beam having a wavelength selected to provide activating radiation to expose a pattern in the photoresist layer formed over the substrate of the master disc between a lower intensity for exposing a groove in the photoresist layer and a higher intensity for exposing the groove and a pattern of depressions in the groove in the photoresist layer; and a second optical modulator for frequency-modulating an intensity-modulated second laser beam with a wobble-frequency to cause the exposed groove to be a continuously frequency-modulated groove.
