New and innovative aspects
CODA is a low cost, individualised product designed for use in anticounterfeit labels that uses light beams to produce unique patterns of light. These patterns can be read on a hand-held device. CODA technology can be used for many anti-counterfeit security purposes. Examples include security inks, tamper proof labels and security holograms. Currently, many of these products use a broad range of technologies but it is hoped that CODA will improve covert security in these areas, therefore removing the need for several security labels on a single product.
Main advantages of its use
CODA offers a number of advantages over existing anti-counterfeit technologies:
• Tamperproof – CODA adds a tamperproof layer of security to a product.
• Unique fingerprint – DOAD technology uses light beam patterns that cannot be easily duplicated.
• Covert – CODA is covert and machine readable for authentication purposes.
• Unobtrusive – the label is transparent and requires very little packaging ‘real estate’.
• Works in low-level and ambient light – DOAD technology works even in limited light conditions.
• Authentication and traceability – CODA is easily individualised and combines the two most important interests of covert security; authentication and traceability
CODA is a transparent plastic photopolymer layer containing a diffractive optical authentication device (DOAD). The DOAD produces a specific pattern of light beams that can be read via a separate machine but are practically invisible in room lighting. DOADs work by creating a pattern that corresponds to a geographical area, product batch or line. When a product is checked, a pattern that corresponds to the DOADs pattern can be certified as genuine. Similarly, if a pattern on a product does not match the DOAD pattern it can be noted as counterfeit. CODA technology is novel, efficient and easily incorporated into existing security systems. By using CODA, the user gets a level of security that is not currently commercially available on the market
CODA’s principal application is as a covert anti-counterfeit label. This would be of interest to companies in a range of industry sectors, particularly those which rely on high-quality, efficient security for their products such as pharmaceutical and consumer goods. CODA simply adds an extra level of covert security to existing systems. By using a transparent plastic layer on products, the user can be sure of the security of their product without the use of intrusive tags. CODA technology prevents the sale of counterfeit products, therefore improving the marketplace for both consumer and seller.
Current development status
The research team has developed the method and processes for the large scale production and fabrication of these devices. These methods allied to the use of the IEO’s patented photopolymer material makes it possible to obtain high efficiency devices.
Desired business relationship
DIT is currently seeking expressions of interest from companies interested in licencing and developing the product.
