Counterfeit Prevention and Detection of University and Academic Institutions Documents Using Unique Codes

摘要

The invention is related to a system that includes an integrated system for online and real-time authentication of documents using uniquely generated codes and the verification of the authenticity of the documents using online verification data identified by the unique codes. The invention contains 3 independent claims.;In this invention, the unique code (3.8) uniquely identifies a document issued by any organization for any type of documents in any part of the world, and uniqueness is guaranteed. The invention also uses another type of code, a 16 hexadecimal digit code (3.7), which is unique across all documents belonging to a single organization. The invention also uses a KAPTCHA code (3.5), which safeguards the document against auto scan and image processing and optical character recognition.;The unique code (3.8) is embedded within a technology convenient for hiding, encrypting and easy readability of the code, which can be one of a quick response (QR) two dimensional code (3.1), a near filed communication tag (NFC) (3.2), an optical medium strip (3.3), a magnetic medium strip (3.4), or a radio frequency RFID tag (3.5).;The system stores the Meta data of the document (3) which is used to generate the codes as well as the generated codes themselves and a PDF file of the document (3) and/or a photocopy of the document (3) in a secure server for verification purposes.;The verifier (4) can verify the authenticity of the document by either scanning the QR code (3.1) or the NFC tag (3.2) or the optical strip (3.3) or the magnetic strip (3.4) or the RFID tag (3.5) using a special application and submits the code hidden within the QR, NFC, optical strip, magnetic strip, or RFID to the verification server. Alternatively, the verifier (4) can use the 16 hexadecimal digit code (3.7) to access the verification server and performs the verification.;The verification server presents to the verifier all information necessary to establish the authenticity and validity of the document.;Besides authentication, verification, and counterfeit prevention and detection, the invention is also a method for tracing the verified documents based on identity, and location of the verifier.
