Synthetic DNA Molecular Code
U.S. Patents – 6,082,775 & 6,106,021
CodeSafe® offers unique Non-Organic “DNA” Molecular Code protection for absolute court enforceable authentication on any security document. The CodeSafe® technology can be verified immediately in the field by three methods:
Verifying CodeSafe® with a black light will cause the CodeSafe® area to fluoresce to blue.
Inspection with a specially tuned laser will cause CodeSafe® to flouresce to a red/orange color.
Inspection with a go/no go audible reader is ideal as a higher level of field verification.
For exact code identification, a spectral analysis can be accomplished in a forensic laboratory to assure document authenticity.
1 – UV
2 – Laser
3 – Audible
- The first tier of “field verification” is a fluorescing reaction from the CodeSafe® when targeted with a black light. More than just UV black light verification, we view this as an important tool in catching a thief. The taggant embedded in CodeSafe® has never been reverse engineered. A typical counterfeiter, when looking for covert security features will assume that the fluorescence is just a UV fluorescing patch, not realizing that it holds other forms of verification. This dual fluorescing reaction is also known as “up and down” conversion.
- As mentioned in the UV description, this is the second tier of field verification. This laser device is specially tuned to an exact wavelength designed to react with CodeSafe®; undeniable secure document verification is achieved with the laser’s red/orange fluorescent reaction. This wavelength is out of the normal visual spectrum of light making the beam invisible to the human eye, but will fluoresce when targeting the CodeSafe® area. Once again, due to its up and down conversion characteristics, the CodeSafe® will react by turning a different color, dependent upon which wavelength of light that targets it.
- The third tier of “field verification” shows an audible reader. This reader has an audible tone plus the signal of a green light (shown in picture) that signifies the authenticity of your secure document. This reader, as with the laser pen, is specially tuned to the CodeSafe® patch and will only react when it’s near a CodeSafe® area. Dependent upon the “loading” of the CodeSafe®, the reader is able to give solid verification through a substrate. Our security envelope is a good example of an application that could use CodeSafe® on the interior and be verified through the envelope without ever needing to be opened. Likewise, any document with a printed CodeSafe® seal could also be verified while still inside the sealed envelope.
