Examples of applications to which RDNA can offer ultra-secure counterfeit protection include:


Because the RDNA process requires nothing to be added to the document, it is straightforward to add to an existing security application.

While RDNA technology can scan a selected area on an identity document such as passport and confirm that the profile matches the one recorded when the passport was originally registered, it can also check that no changes have been made on the personal details page, i.e. while RDNA identifies the characteristics of the underlying material, it can also authenticate any ink or other substances subsequently added to it.

In the case of passports this means that the system can, for example, scan the MRZ as well as the photograph of the holder and the holder’s name to check that the key data elements have not been tampered with. Swipe scanheads are small enough to be added to existing passport readers, so there is no visible or operational change to the process. Once scanned, the profile of the material of the selected areas is determined, and encrypted as a digital string.

The above process is first undertaken at the point when a new passport has just been personalized for an individual. While RDNA makes it easy to add the profile string to the record in the existing passport database, it can be kept in a separate database (together with the passport number) if required.  For certain applications there’s a benefit in holding it on the document itself, either on an RFID chip, a magnetic stripe, or in a barcode format such as PDF 417. This makes the document self-authenticating.

When the passport is presented at Immigration, it is rescanned and the resulting profile matched against the one generated at time of issue. If the profiles don’t match, the passport is counterfeit. This cannot be circumvented.

Unlike all alternative protection methods, a new document does not have to be issued to add RDNA protection. As long as the current document can be confirmed to be genuine, it can be encoded and its details added to the database when next presented to an immigration officer.


Currency is clearly a different application to passports, ID cards, etc, as generally the need is not to validate a specific banknote against its serial number (although this can be done), but to confirm that it is a genuine note rather than a counterfeit, i.e. that it fits within a Gold Standard. A banknote is actually three-dimensional, such that the 3-D profile of any denomination is predictable and unique. While the surface of a note only varies at the microscopic level, RDNA can detect this and by combining it with the ink and print pattern, readily identify the type of note involved as well as the authenticity of the security ink used for printing. This can apply to any banknotes from any country, so a generic banknote authenticator can be customized, programmed, and configured via software in-country to that country’s currency, simply by reading notes that are known to be genuine and developing a gold standard for that denomination of note.


RDNA is well-suited to validating that documents transferred between bank branches and regional/head offices, or between banks, are not tampered with. Taking a bank draft as an example, it can be scanned when initially produced in a branch, and its profile sent to a central server. When subsequently presented by the recipient it is scanned again and the profile matched against the original. By positioning the scanhead to read along, for example, the line stating the amount of the draft, any change in the pattern of the ink on the paper will be detected, as well as confirming that the paper itself is the original and not counterfeit. Multiple heads can be incorporated in the scanner if required so that other lines (e.g. the signature and/or date lines) can be profiled as well.

RDNA is available in client-server and application-server models. Where a bank prefers to operate on a transaction fee basis, Rogue DNA offers access to its own application server, minimizing the time and upfront cost involved in setting up and running the system.

Where access to a central server is impractical, the system can work on a closed-loop approach, where the profile is encrypted and printed back on the document as, say, a 2-D barcode. When the document is subsequently read the profile is matched against the decrypted barcode. If the two don’t match the document is counterfeit or has been tampered with.

RDNA offers banks the ability to confirm in real time that any draft, cheque, or other secure document is the original and has not been altered.


A major application of RDNA technology is brand protection. RDNA technology provides the manufacturer and each party in the distribution channel with a means of easily determining whether a product is genuine or not.

The basic system works on a closed-loop basis by authenticating the label using a handheld scanner containing optical/electronic technology. During the production process the RDNA profile of the label is determined by scanning an area on the label defined by pre-determined coordinates. This can then be profiled, encrypted, and the resulting string printed back on the label as a barcode in the user’s format of choice.

Where access to broadband is available, a central database of label usage is maintained, ensuring that each label is only used once.

While the current RDNA scanner uses a motorized feeder mechanism for paper documents, the brand protection scanner uses a static page reader. When triggered, the scanner captures an image of the label. RDNA firmware parses the image to separate out the standard barcode and the RDNA profile. It will then analyze the predefined area inside the markers, generate the new profile, and match it against the version printed on the same label during manufacture. If they don’t match, the product the label is attached to is counterfeit. The label can’t be removed or switched because the encrypted barcode will be used to record the transaction and generate the customer receipt.

This approach enables us to produce a generic handheld scanner that can be adapted and packaged to any type of label with a minimum of modification. This application supports many vertical markets – from luxury goods to circuit boards, cigarette cartons, spare parts, etc.
