Provided is a security device for securing a substrate comprises at least one connection device, and at least one output device. The security device is configured to be connected to the substrate via the connection device. The output device is configured to emit at least one output signal. The output signal is outputted to an outside of the security device when the connection device and the output device are coupled to one another. A change in the coupling between the connection device and the output device results in a change in the output signal or in an absence of the output signal, and wherein the change in the output signal or the absence of the output signal is indicative of a manipulation of the security device and/or of the substrate. Other embodiments disclosed.

Security device for securing an article such as a passport

Provided is a security assembly including at least one substrate element, at least one first pattern, and at least one second pattern. The at least one first pattern is associated with the at least one substrate element. The at least one first pattern is at least in part translucent or transparent. The at least one second pattern is associated with the at least one substrate element. Each of the at least one first pattern overlaps at least in part the at least one second pattern. Upon viewing the assembly, the at least one first pattern and the at least one second pattern are configured to generate, at at least one side of the assembly, at least one third pattern, each of the at least one third pattern including an optically variable image.
