An image captured for a currency note is preprocessed to correct pixel intensity values to expected pixel intensity values. The corrected image is passed to a currency validator for determining whether the currency not is genuine or non-genuine.

The disclosure relates generally to checks and other negotiable financial instruments and particularly to mitigating exposure to financial fraud. Specifically, the disclosure relates to systems and methods of authenticating checks issued by a first entity for the benefit of a third party.

The SACOS apparatus solves counterfeiting issues instantaneously and develops new security features in order to improve the role that international regulatory commissions, governments, and central banks play to effectively fight counterfeiting.

Existing currency validation (CVAL) devices, systems, and methods are too slow, costly, intrusive, and/or bulky to be routinely used in common transaction locations (e.g., at checkout, at an automatic teller machine, etc.). Presented herein are devices, systems, and methods to facilitate optical validation of documents, merchandise, or currency at common transaction locations and to do so in an obtrusive and convenient way. More specifically, the present invention embraces a validation device that may be used alone or integrated within a larger system (e.g., point of sale system, kiosk, etc.). The present invention also embraces methods for currency validation using the validation device, as well as methods for improving the quality and consistency of data captured by the validation device for validation.

A method of authentication using surface paper texture includes steps of capturing a topographic pattern image of a surface of a region of interest of the paper artifact and extracting a plurality of specific features from the captured topographic pattern image. The method further identifies the location of the specific features of the paper artifact from the captured topographic pattern image. A bit map of the identified location of the specific features is generated. Then, a reference image of a reference bit map printed on the region of interest of the paper artifact is captured. Finally, the method compares the generated bit map with the captured reference bit map to generate a score. The score of the comparison determines the level of authentication. The method provides an offline method of authentication.

According to one embodiment, a sheet processing apparatus includes: an image acquiring device configured to acquire a sheet image that is an image on a sheet; a setting portion configured to set a reference area in the sheet image acquired by the image acquiring device, wherein the setting portion repeats moving the reference area from a starting position to an end position in a first direction by a first moving width, and, upon the reference area reaching the end position, moving the reference area in a second direction intersecting the first direction by a second moving width; a degree of similarity calculating portion configured to extract a feature from an image in the reference area set by the setting portion, and calculate a degree of similarity between the extracted feature and a typical sheet pattern; a moving width calculating portion configured to calculate the first moving width and/or the second moving width based on the degree of similarity calculated by the degree of similarity calculating portion; a position specifying portion configured to specify a position at which the typical sheet pattern is present in the sheet image based on a plurality of the degrees of similarity calculated by the degree of similarity calculating portion; and a kind of sheet discriminating portion configured to discriminate a kind of the sheet based on the sheet image at the position specified by the position specifying portion.

Systems for item validation and image evaluation are provided. In some examples, a system may receive an instrument and associated data. The instrument may be received and a user profile may be retrieved. The user profile may include a plurality of previously processed instruments that have been determined to be valid and/or authentic. The instrument may be compared to the plurality of previously processed instruments to determine whether one or more elements of the instrument being evaluated match one or more corresponding elements of the plurality of previously processed instruments. Matching or non-matching elements may be identified. In some examples, one or more user interfaces may be generated displaying the instruments and including any highlighting or enhancements identifying matching or non-matching elements.
