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.

The security document, such as a passport, comprises a lightguide having an incoupler structure and in outcoupler structure. The outcoupler structure is sparse in the sense that any part of the protective area is close to a part of the outcoupler structure. However, to secure a large protective area with a limited amount of incoupled light, outcoupler structure covers no more than 20% of the protective area. This allows to protect a large area of the security document, such as a photograph or other personalized information, by means of the lightguide.

An identity document and method for manufacturing the identity document, the method including providing a document body that includes at least a first and a second transparent external layer and a white central layer, the white central layer including a transparent substrate at least partially covered with a photosensitive opaque white coating, and exposing at least a point of the photosensitive opaque white layer to a first radiation, the radiation being able to perform ablation of the photosensitive opaque white layer, so that the point exposed to the radiation becomes transparent, and so that light passes through the thickness of the identity document at that point.

Methods, systems, and devices are provided for an authentication system configured to verify the identity of a person. According to one aspect, the system can determine that a first set of image pixels contains a first side of an authentication document. The system can determine that a second set of image pixels contains a second side of an authentication document. The system can determine whether the first side of the authentication document of the first image and the second side of the authentication document match. The system can compare a third image with the first image and determine whether the third image and the first image match to the same person. And the system can perform each step of authentication after receiving an image and prior to requesting more images from the user, reducing the overall processing time.

A system is capable of generating identifications that include distinctive line patterns corresponding to different portions of secure customer information. In some implementations, data indicating one or more linear patterns and data indicating customer information to be embedded within an identification document is obtained. Respective subsets of the customer information are assigned to each of the one or more linear patterns. A photographic image to be included within the identification document is then modified based at least on generating a portion of the photographic image that is composed of at least one of the one or more linear patterns. The modified photographic image is then disposed on an identification document to yield embedded customer information.

A multilayer identification document including a first layer including a color component of a color image and a second layer including a grayscale component of the color image, wherein the grayscale component is laser-engraved on the second layer. The color component is printed on the first layer and defines a multiplicity of voids in a preselected arrangement. The color component and grayscale component are at least partially superimposed to yield a hybrid color image.
