Techniques are described to embed graphical identifiers into a ghost image within a layer of laminate of an identification document. The ghost image includes optically variable media that has a first appearance when viewed from a front of the identification document in reflected light at a first angle and a second, different appearance when viewed from the front of the identification document in reflected light in a second, different angle. During the ghost image generation process, a graphical identifier can be placed on a baseline ghost image to generate an adjusted ghost image. Once the adjusted ghost image is printed onto the identification document, the graphical identifier can be viewable based on the appearance of the adjusted ghost identifier in relation to the reflected light.

Aspects described herein may provide detection of a physical characteristic of a credential, thereby allowing for authentication of the credential. According to some aspects, these and other benefits may be achieved by detecting the physical characteristic with the credential. An image of a credential may be received. An optical characteristic of a secure feature of the credential may be determined. An expected optical characteristic of the secure feature may be determined based on known properties of the secure feature. A determination as to whether the credential is authentic may be based on a comparison of the determined optical characteristic of the secure feature to the expected optical characteristic of the secure feature.

A user is guided to move a device equipped with an illuminator and a camera with respect to a document whose genuineness is to be assessed. The motion includes changing the distance between the device and the document by moving the device or moving the document. Imagery of the document is captured during the movement and analyzed to determine a likelihood that the document includes features indicative of genuineness, such as a hologram, an original photograph, and other regions matching those of a genuine document. The analysis may include identifying regions exhibiting large changes in appearance over relatively small distance changes which characterize holograms, and obtaining the spatial extent of document features.

A security document with a first security element, which includes a first item of visually recognizable and in particular machine-readable information, and a second security element, which includes a second item of in particular machine-readable information which can be used to verify the first item of information. A method for the authentication thereof is also described.

The disclosure relates to the technical field of secure identification document, specifically to a method for producing a color secure identification document and a color secure identification document thereof. The method comprises: etching identity information on the substrate of the data surface of document by laser, and the identity information comprises a black-and-white image and text information; printing a color image on the black-and-white image with color ink so that the color image and the black-and-white image are aligned and coincide with each other to form a personalized data surface; and printing a transparent protective layer on the upper surface of the personalized data surface with a transparent varnish, wherein the protective layer covers the color image.

Security features used on identification documents such as plastic cards and passport pages are described. The security features include a textured portion that is formed on a portion of the surface of the identification document using a laser. The security features can also include a printed portion and/or a laser marked portion. The printed portion (if present) can be formed above or beneath the textured portion. The laser marked portion (if present) is formed within the thickness of the identification document below the textured portion. The textured portion and the printed portion and/or the laser marked portion can be in congruence with one another to form the security feature.
