Patent attributes
According to various embodiments, a shipping label validation system is provided for determining whether a shipping label is valid or counterfeit. The system may be used, for example, by a shipping entity (e.g., a common carrier) to prevent counterfeiting by generating and embedding onto the shipping label a shipping label hash index based upon at least a portion of the data located on the shipping label. The shipping label data may include, for example, a sender's address, recipient's address, package weight, tracking number, routing code, service code, and/or MaxiCode. The system may also be used to detect existing counterfeit shipping labels by independently generating a confirmation hash index based upon the same portion of the data used to calculate the shipping label hash index. In various embodiments, the system identifies counterfeit shipping labels based upon any discrepancies revealed when comparing the shipping label hash index to the confirmation hash index.
