Hydrophilic surface application for anti -

The sale of counterfeit goods is a significant issue facing consumers, industry, and governments. The Internet heightens the counterfeiting problem as counterfeiters find simplified means and additional channels in the virtual world to promote and sell counterfeits. Anti-counterfeiting technology can help protect consumers and businesses by assuring them that the goods they receive are legitimate. Disclosed is a novel anti-counterfeiting method utilizing hydrophilic surface treatments.

    Hydrophilic coatings can be deposited on a surface in a pattern. When water is deposited onto the surface, it will gather on the hydrophilic surface. The pattern and location of the hydrophilic surface can be unique to each component to prevent counterfeiting. The coating can be applied in a variety of patterns (company name, bar code, etc.) using a mask to block off areas where the hydrophilic coating will not be applied. A user can then check authenticity by applying water or other liquid to the surface of the item. With the hydrophilic coating, the liquid will only collect where the treatment is applied, thereby verifying that the item is authentic.

    The figure below discusses the process of this disclosure. A component surface is prepared to receive the superhydrophilic treatment. [1,2,3] A mask is applied to the component surface and the coating is then applied. When the end user wants to determine authenticity, a liquid water or oil...
