Description

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] In various embodiments, the invention relates to analyzing data associated with taggants contained within an adhesive sealant for authenticating performed work and forensically linking parts and assemblies according to their configuration management and control scheme throughout the lifecycle of the manufactured good. In particular the present invention relates to embedding identification data into an adhesive sealant material that is extruded onto various surfaces of assemblies to enable visual inspection of tampering and quality control while creating a forensic layer of authentication data, unifying parts and assemblies within manufactured systems using taggant identifier data.

[0017] The present invention allows for the interrogation of taggant data contained within an adhesive inspection sealant applied throughout manufactured assemblies systems and subsystems for traceability and determining if an original equipment manufacturer (OEM) or unauthorized party performed work on the system.

[0018] Molecular markers and taggants described in prior art can be embedded into products and various mediums to embed unique identifier data for one item or a batch or items. The identifier data enables product traceability for anti-counterfeiting purposes.

[0019] Various anti-counterfeiting technologies were developed to mitigate the risk of counterfeit products entering supply chains. Packaging technologies such as holograms, barcodes, QR codes, special pigments and dyes protect product packaging, but do not authenticate the physical product. Furthermore, counterfeiters are mimicking packaging technologies meant to authenticate goods, thereby defeating the reliability of package-only protection technologies.

[0020] Physical and chemical taggants have been developed to protect at-risk materials such as fuels, bulk chemicals, and other products. These taggants can be composed of organic molecules, inorganic fluorescent markers, or nucleic acids such as deoxyribonucleic acid (DNA). Conventional taggant technologies contain data about products or they are associated with authentication and traceability data. In simple systems, if the taggant is present but does not contain data that can be interrogated and decrypted, its mere presence may indicate a product is authentic.

[0021] DNA authentication technologies are gaining traction in various industries because of DNA's scalability as well as its ability to hide in plain sight; DNA can be embedded in materials without disclosing the exact DNA sequence. Like barcodes in the super market or unique fingerprints, DNA sequences are data codes that can be customized for a unique authentication signature.

[0022] DNA sequences are synthesized into physical DNA molecules. The synthesized DNA molecules can be embedded into materials such as chemicals or surface witness marks for authentication purposes. Due to the prevalence of DNA in environmental conditions, unless a user knows the target sequence they are looking for, it is nearly impossible to interrogate a DNA taggant using the polymerase chain reaction (PCR) analytical method.

[0023] Industrial applications may not rely on authenticating one part or item. Rather, manufactured assemblies and sub-assemblies may be comprised of various parts that adhere to a configuration management and control scheme. For example, aircraft configuration management and control governs specifications of various parts and spares as well as the conditions in which parts are modified, introduced, or released into the manufacturing process. Taggants can be specific to an aircraft or a subassembly. For example, an airplane fuselage can be assigned its own taggant material. Later, critical parts can be marked only with the same material containing an identical taggant that matches the original parts and configuration.

[0024] Primers and probes hybridize with complementary nucleotides of the target DNA sequence. In PCR, primers and specifically probes bind to the correct DNA fragment assuming the adenine, thymine, guanine, and cytosine pairs match. Probes are used in the PCR process to detect the target sequence and help with target sequence detection.

[0025] Instead of compromising the DNA taggant's authentication security sequence by embedding DNA taggants into a mark of inspection paint, primers and probes would solve possible sequence decryption by obfuscating the DNA taggant's sequence. Primers and probes are designed to be specifically compatible with a unique nucleic acid sequence. In an embodiment of the present invention, an operator would interrogate the primer and probe chemistry present in a given sample, match that data to a computer networked system lookup table, and determine if the target DNA sequence matches the witness mark's unique primer and probe signature.

[0026] The present invention covers another embodiment wherein designer molecules are uniquely synthesized to pair with a DNA sequence. For example only, pyrrole-imidazole (Py-lm) polyamides recognize and bind DNA with specific sequence characteristics. They are aromatic ring, synthetic small molecules that have a high affinity of binding with compatible DNA double helixes.

[0027] Py-lm molecules can be embedded within various products, fluids, bulk chemicals, and other materials for authentication purposes when associated with a given DNA sequence. Py-lm data can protect the identity of a DNA sequence associated with a certain authentication security scheme.

[0028] The compounds used to formulate the present invention aid in the homogenous distribution, suspension, durability, and viability of the taggant. In order to achieve this, a colloid was developed. Colloid solvent chemistry was also selected to help blending and ballasting of taggant particles, and maintain consistent and event distribution during manufacturing, shipping, handling, long term storage, prior to, and after the present invention has been opened and partially used. Tack time under 30 seconds was needed, while at the same time, quick and simple solvent sample extraction that is uniform of the taggant was necessary.

[0029] Turning now to FIG. 1, a piping system 100 is shown having torque specific couplings 110. Adhesive sealant 120 having molecular taggants contained therein are shown applied to the surface. These serve as witness marks for tempering, but more importantly, are sophisticated evidence of the authenticity of the parts making up piping system 100. The sealant may be integrated and a DNA sequence verified through PCR.

[0030] In FIG. 2, a known DNA sequence A is present in the sealant used on all of the nuts 140 after assembly.

[0031] In FIG. 3, it has been determined that B DNA is present on some bolts. If part of a maintenance plan, the pressure of B DNA indicates that authorized work was performed subsequent to the original installation. If no DNA is present, the work was not authorized.

[0032] The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims, rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
