Multispectral imaging technology is a direct imaging approach where the object is illuminated under multiple illumination states and an image is collected for each of those states. If a two-dimensional barcode is presented and imaged, the barcode can be read using standard techniques and then authenticated with a Lumidigm device.
Lumidigm barcodes are printed on media containing copy-resistant features such as holograms or color-activated inks. A replica of a copy-resistant barcode, even a high-quality color copy, can be distinguished from an authorized barcode using techniques similar to those used in Lumidigm’s liveness detection. In addition to copy protection, the message contained in the barcodes can be encrypted using standard, trusted algorithms which ensure the barcode cannot be altered or read by devices other than the authorized sensors.
With this unique capability, Lumidigm technology can read and authenticate a credential (barcode) and verify that the person carrying the credential is the authorized individual (fingerprint) — all with a single sensor. In this way, our customers can add a second factor to their authentication solution for the cost of credential issuance — and without the added cost of additional hardware.
Some customers want to eliminate the credential altogether. In today’s BYOD (bring your own device) environment, people expect to transact with their smartphone or other mobile device. It is possible to transmit an encrypted barcode to a smartphone and for the user to wave it over the Lumidigm sensor. The barcode is read, decrypted, and decoded and then the user is prompted to confirm with their fingerprint that they are the authorized individual.
Two factor authentication using a single sensor — that’s the Lumidigm Advantage.
