Abstract:
The present disclosure is drawn to a method and system for the excitation, identification, and authentication of light emitting materials using a mobile device comprising at least one Vertical Cavity Surface Emitting Laser (VCSEL), for use in a variety of applications.
Abstract:
A method for authenticating an object, comprising determining a physical dispersion pattern of a set of elements, determining a physical characteristic of the set of elements which is distinct from a physical characteristic producible by a transfer printing technology, determining a digital code associated with the object defining the physical dispersion pattern, and authenticating the object by verifying a correspondence of the digital code with the physical dispersion pattern, and verifying the physical characteristic.
Abstract:
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.
Abstract:
A method for determining a manipulation or forgery of an object which is identified with a graphical representation of an information, wherein the graphical representation of the information forms light and dark regions and the object has a surface having a contrasting, irregular microstructure. A system is also related, the system being suitable for carrying out the method according to the invention.

Abstract:
Provided is a system and a method for generating and authenticating a digital signature on a physical document. The system and method includes the use of a document having a code embedded therein (e.g., a Radio Frequency Identification Code and/or a Near Field Communication Code), a first user computing device having a first user application software and a code reader, a second user computing device having a second user application software and a code reader, a printer for printing a digital signature on the document, and a main application server for generating, encrypting and authenticating a digital signature, the data integrity of the document and status of the document.
Abstract:
Systems and Methods for identity information verification. The system includes an electronic device and a computing authentication unit. The electronic device includes a data capture unit for electronically scanning first data and second data corresponding to respective first and second locations of an identity document indicative of an individual. The computing authentication unit is configured to: perform a first verification to verify whether the first data matches the second data; perform a second verification, when the first data matches the second data, including comparing aggregated data from both the first and second data to identity data in one or more identity databases to verify personal identity information of the individual indicated in the identity document; and cause the electronic device to indicate a result of at least one of the first verification or the second verification.
Abstract:
Polymer microparticles spatially and spectrally encoded using upconversion nanocrystals (UCN) are described for labeling of articles and tissues. UCN having spectrally distinguishable emission spectra are disposed in different portions of an encoding region of each microparticle.
Abstract:
An authentication system is provided. The authentication system may include an object, predetermined data, an encrypted barcode, an authentication device, a computer and a database. The database may include a plurality of associations between a random unique number and an object and predetermined data thereof. The encrypted barcode may include barcode information, such as but not limited to, predetermined data and the random unique number. The barcode information may be encrypted so that only the database may decrypt. A user may use the authentication device to machine read the encrypted barcode of the object. The authentication device may remotely communicate the encrypted barcode to the database so that the database may perform process steps, including: comparing the barcode information containing a specific random unique numbers with the plurality of associations so as to identify the association having the identical specific random unique numbers; and authenticating whether the association having the identical specific random unique numbers contains identical predetermined data as the barcode information containing the specific random unique numbers. A failure of either identification and or verification may be communicated to the authentication device.
Abstract:
A method and apparatus for determining a digital signature from an article. A coherent light source directs a beam to illuminate the article and a detector arrangement collects data points from light scattered from many different parts of the article to collect a large number of independent data points, typically 500 or more. By collecting a large number of independent signal contributions specific to many different parts of the article, a digital signature can be computed that is unique to the area of the article that has been scanned. This measurement can be repeated whenever required to test authenticity of the article. Using this method, it has been discovered that it is essentially pointless to go to the effort and expense of making specially prepared tokens, since unique characteristics are measurable a in a straightforward manner from a wide variety of every day articles.
