A security insert with at least one optically recognizable character and at least one tactilely detectable character for an identity document comprises at least a first at least partially transparent layer which has blackenings which form at least one optically recognizable character. A varnish arrangement forming at least one tactilely detectable character is disposed on a layer of the security insert. The at least one optically recognizable character is, at least from the perspective of an observer of the security insert, partially overlaid by the at least one tactilely detectable character, wherein at least a portion of the outer contours of the at least one tactilely detectable character is optically recognizably reproduced by the optically detectable character.

A display body includes a base material having a first region, a second region, and a third region. In the display body, the first region is formed with a code or an image of identification information, and the second region is formed with a hidden code containing information obtained by encoding at least a part of the identification information. An encrypted ciphertext is recorded in the third region, and the ciphertext is generated from at least one of the code of the identification information and the hidden code.

A security device and a method for verifying such a security device are disclosed. The security device has at least two security features. At least one of the security features is a tamper-evident security feature, which is configured to alter irreversibly upon mechanical tampering with the security device. At least one other of the security features is a robust security feature, which is robust against tampering with the security device. The at least two security features can be extracted from at least one image of the security device with a programmable device having a camera at least in an intact state of the security device.

A reading device, a reading method and a reading program that can easily and quickly read a composite symbol, and a settlement processing method are provided. A moving image of a composite symbol which includes a plurality of symbols emerging in the same location and whose appearance changes depending on a viewing angle, is captured. The symbols included in the composite symbol are detected from the moving image obtained by image-capturing. Authenticity of the composite symbol is determined based on the obtained moving image.

Systems and methods to authenticate a security device are disclosed. In one aspect, embodiments of the present disclosure include a method for capturing, by an optical sensor, sequential image frames of the security device. From the sequential image frames of the security device, changes to an optical property of the security device can be measured. The optical property can include an optical refractive property. In a further embodiment, changes in optical refractive properties of the security device can be identified from the changes to the optical property measured from the security device. It can be further determined whether the changes in the optical property matches or fails to match a valid change.

There is provided a holographic security element including a substrate; and an array of nano-reflectors configured to form a pattern on the substrate and to generate a holographic image corresponding to the pattern at a predetermined distance from the substrate when irradiated with a predetermined light source. In particular, the array of nano-reflectors is configured to generate the holographic image at the predetermined distance to have a size that is larger than a size of the pattern. There is also provided a method of forming the holographic security element, and an article having one or more holographic security elements incorporated therein.
