Abstract: In one embodiment, an authentication area on a portable object comprises a random arrangement of printed LEDs and a wavelength conversion layer. The object to be authenticated may be a credit card, casino chip, or other object. When the LEDs are energized during authentication of the object, the emitted spectrum and/or persistence of the wavelength conversion layer is detected and encoded in a first code, then compared to valid codes stored in the database. If there is a match, the object is authenticated. The LED power may be remotely inductively coupled and may flash the LEDs, while the wavelength conversion layer emission slowly decays during its optical detection. The flash of blue LED light may be emitted from the edges of the object, which may act as a light guide, for optical feedback to the user that the object is being authenticated.

Abstract: In one embodiment, a printed LED area comprises a random arrangement of printed LEDs and a wavelength conversion layer. The LED area is embedded in an object to be authenticated, such as a credit card or a casino chip. The object may include a light guide for enabling the generated light to be emitted from any portion of the object. In one embodiment, when the LEDs are energized during authentication of the object, the existence of light emitted by the object is sufficient authentication and/or provides feedback to the user that the object is being detected. For added security, the emitted spectrum vs. intensity and persistence of the wavelength conversion layer is detected and encoded in a first code, then compared to valid codes stored in the database. If there is a match, the object is authenticated.

Abstract: In one embodiment, a printed security mark comprises a random arrangement of printed LEDs and a wavelength conversion layer. During fabrication of the mark, the LEDs are energized, and the resulting dot pattern is converted into a unique digital first code and stored in a database. The emitted spectrum vs. intensity and persistence of the wavelength conversion layer is also encoded in the first code. The mark may be on a credit card, casino chip, banknote, passport, etc. to be authenticated. For authenticating the mark, the LEDs are energized and the dot pattern, spectrum vs. intensity, and persistence are converted into a code and compared to the first code stored in the database. If there is a match, the mark is authenticated.
