Abstract
Methods for authenticating an article with a cyanoacrylate solution comprising a water soluble security marker compound are described. The methods for producing a nucleophilic security marker/cyanoacrylate solution as well as methods for labeling an item and detecting the nucleophilic security marker/cyanoacrylate from an item being authenticated are also described. A method for using a nucleophilic cyanoacrylate security marker for antitheft purposes is also described.
Claims30
A method of making a security marker, comprising:
- providing a water soluble security compound in a aqueous solution and a co-solvent,
- adding said water soluble security compound to said co-solvent in an amount to produce a water soluble security compound/co-solvent solution,
- providing a cyanoacrylate solution, and
- incorporating an amount of said water soluble security compound/co-solvent solution into said cyanoacrylate solution to produce a water soluble/cyanoacrylate security marker solution.
A method for authenticating an article, said method comprising:
- providing a cyanoacrylate security marker solution, the cyanoacrylate security marker solution comprising a water soluble security compound and a co-solvent;
- applying said cyanoacrylate security marker solution to an article of interest;
- collecting a sample of said cyanoacrylate security marker from the article of interest;
- analyzing said sample of said cyanoacrylate security marker for said water soluble security compound;
- detecting said specific security compound;
- and
- verifying that the article of interest is genuine.
A method of using a nucleophilic cyanoacrylate security marker for anti-theft purposes, the method comprising:
- providing a nucleophilic cyanoacrylate security marker solution, a triggered exploding device and an item to be secured, said item to be secured being housed in a secured container;
- placing said nucleophilic cyanoacrylate security marker solution into said triggered exploding device;
- and
- placing said triggered exploding device comprising the nucleophilic cyanoacrylate security marker solution into the secured container.
