ABSTRACT:
Techniques for authenticating certificates of authenticity (COAs) are discussed. The techniques provide for a simplified authentication system that is easily utilized in a field setting. In described embodiments, COAs are attached to or otherwise associated with goods to be authenticated. The COAs incorporate random or pseudo-random arrangements of optically sensitive fibers to create unique identifiers. A COA reader device optically scans each COA and characterizes the COA according to its unique arrangement of optical activity. A COA reader device may also scan data (e.g., a barcode) that is associated with the COA. The data contains information about the COA to further strengthen the COA authentication process. Based on the scan, the goods associated with the COAs can be verified as genuine (i.e., not pirated).
