The Counter-Terrorism Currency System is a type of currency designed to combat financial fraud and Terrorism. The Counter-Terrorism Currency System is also known as the CT Currency System

The CT Currency will be in two forms.

The CT Paper Currency and the CT Digital Currency

The CT paper Currency will be paper money with an embedded CT Code, which stands for “Counter-Terrorism Code. “This CT code allows users to scan the CT paper currency with their smartphone through the CT Currency Mobile App.

Both sides of the CT paper Currency will be embedded with the CT code. one side is for transactions, and the other is for the bank used only. The bank used the only section used by the bank whenever the paper gets lost to find the rightful owner.

A method for authenticating a security document by means of at least one device includes: a) providing the security document having at least one first security element and at least one second security element; b) providing the at least one device, wherein the at least one device includes at least one sensor; c) capturing first items of optical information of the at least one first security element by means of the at least one sensor of the at least one device during a first illumination, wherein at least one first dataset specifying these items of information is generated therefrom; d) capturing second items of optical information of the at least one second security element by means of the at least one sensor of the at least one device during a second illumination, wherein at least one second dataset specifying these items of information is generated therefrom; e) capturing third items of optical information of the at least one second security element by means of the at least one sensor of the at least one device during a third illumination, wherein at least one third dataset specifying these items of information is generated therefrom, wherein the second illumination differs from the third illumination; f) checking the genuineness of the security document and/or the second security element at least on the basis of the at least one second dataset and the at least one third dataset.

A banknote is irradiated with lights of plural wavelengths. Images of the banknote for each wavelength are acquired. An IR ratio image having a pixel value that is a ratio of a pixel value of the image acquired by the visible light to a corresponding pixel value of the image acquired by the infrared light is generated. The banknote image and the IR ratio image are corrected by a coefficient corresponding to the banknote type, the banknote orientation, and the wavelength. From the banknote image or the IR ratio image, by using the information pertaining to the banknote type, the banknote orientation, and the wavelength, intermediate evaluation values are calculated for each wavelength. Mahalanobis distance is calculated based on the intermediate evaluation values, an average value and a variance-covariance matrix of the intermediate evaluation values, and a degree of soiling is determined based on the Mahalanobis distance.

Provided is a multi-banknote cassette with a movable stopper, which is capable of storing various kinds of banknotes at the same time. The multi-banknote cassette includes a movable stopper which is installed in a stack guide for guiding banknotes introduced into a cassette body of the banknote cassette toward a banknote stopper, and rotated to protrude from or retreat into a transfer path of the banknotes. When a banknote having a relatively small size among the banknotes inserted into the banknote cassette is introduced, the movable stopper is rotated to protrude from the stack guide and regulates the front end of the introduced banknote, and when a banknote having a relatively large size is introduced, the movable stopper is rotated to retreat into the stack guide, and a banknote stopper installed at the rear of the stack guide regulates the front end of the introduced bank.

A document liveness detection method comprising using a hardware processor for prompting an end-user of an electronic device, having a camera, to provide an image sequence of a physical document whose orientation is undergoing change; and image-processing the image sequence to yield an output indication of whether or not the image sequence was generated by capturing a live or physical document; and providing the output indication to at least one computerized system or human.

An identification apparatus or system includes an estimation unit that estimates an operating distance between the surface of an optical device and an imaging unit as an estimated value. A reference distance refers to the distance between a first face of an identification target and the imaging unit and at which light diffracted by a diffraction grating is capable of being recorded by the imaging unit. A first determination unit is included that determines whether the estimated value matches the reference distance and a second determination unit that determines whether an image captured by the imaging unit matches a reference image. Conditions for identifying the optical device as the identification target include a condition that the first determination unit determines that the estimated value matches the reference distance and a condition that the second determination unit determines that the image captured by the imaging unit matches the reference image.
