Abstract
Disclosed is a device and process for marking and detecting labels with spectral band authentication features utilizing a reader that can be affixed to a smart phone and positioned so as to align the lens of the phone's camera with a reader aperture. The reader aperture allows the camera to view an item through a spacer, wherein a UV and IR light source is used to reveal indicia within invisible ink. The light source employs a distinct emission spectrum characterized by narrow peaks and gaps which can illuminate pigment of the invisible ink that is selectively responsive at the wavelengths of specific peaks and/or unresponsive at the gaps in the spectrum. The smart phone captures the indicia revealed and interfaces with a cloud-based database to provide verification of authenticity.
Claims20
An authentication device comprising:
- a reader body having a microprocessor based computer function including a touch screen interface, a camera, memory, internet access, an operating system and a power source;
- a lens attached to said reader body, said lens housing a light source coupled to said power source for producing light of a predetermined wavelength capable of reacting with an invisible ink to reveal a hidden image, said lens communicating with said camera to capture said hidden image;
- wherein said light source illuminates an invisible ink to reveal said hidden image, said hidden image captured by said smart phone and compared with an authentic image stored on a cloud based database to determine authentication.
An authentication device comprising:
- a reader having a front surface and a rear surface spaced apart a continuous sidewall forming a cavity with a power supply, said front surface having a connector mechanism constructed and arranged to physically couple a smart phone to said reader;
- a light source attached to said reader, said light source having a light of a predetermined IR or UV wavelength to which an invisible ink having a wavelength absorptive pigment matched to at least one narror band of said light source and is reactive to reveal a hidden image;
- a lens spacer attached to said support body, said lens spacer housing said light source and communicating with a smart phone camera to capture said hidden image;
- a shroud coupled to a distal end of said lens spacer constructed and arrange to reduce or eliminate ambient light;
- wherein said light source illuminates an invisible ink to reveal a hidden image, said hidden image captured by said smart phone and compared with an authentic image stored on a cloud based database to determine authentication.
A process for authenticating an image on a product or document comprising the steps of:
- printing hidden indicia with an invisible ink;
- affixing a reader device to a smart phone, said reader having a power supply and a selectable IR or UV light source producing a predetermined wavelength;
- placing said reader device and said smart phone over a document containing said invisible ink;
- decoding said invisible ink with said light source to reveal a first image;
- capturing said first image with said smart phone;
- communicating said first image to a cloud based database containing authentic images;
- comparing said first image with said authentic images;
- and
- displaying confirmation of the authenticity of said first image on said smart phone.
