Definitions

  • the invention is a unique digital system in an integrated process that initially prevents counterfeiting of any document issued through our system by any public organization, academic institution, as well as all official and private offices; it also allows for an efficient, effective and fast turn around time for authentication and verification of records.
  • Current Used Technique
  • ID documents, land registry certificates, vehicle licenses and diplomas issued by the academic institutions and organizations are falsified by altering names, validity dates in power of attorney attested by the notary, laboratory analysis results etc. These alterations may not be recognized or identified by the institutions or organizations where such documents are used. Also, cancelled or expired documents to which annotation is attached may not be determined. For example; a document which is attached an annotation after being issued pursuant to the directives may be submitted to and accepted by the organizations and institutions. In the mean time the process of Authentication and Verification is time consuming, costly and difficult.
  • the organization requesting the document may authenticate the document on the system if the organization issuing the document permits. For example, when you go to a notary, your identification may be compared to the particulars in the system of the civil registry office by the notary based on the authorization granted by the civil registry. However, this gives rise to a flaw in system security as an individual other than the civil registry has an access to the system. In other words, identification may be altered in the system and this facilitates fraud.
  • the invention is a unique digital system and a process that is lean, fast, reliable, effective in producing safe documents that can not be falsified and easily authenticated with a press of a button any where in the world.
  • the invention provides a novel technology for preventing falsification of documents by providing an integrated process for the authentication and verification of documents such as those produced by academic institutions and potentially by government and private organizations.
  • the method combines the recent technology advances in coding theory, communications, smartphones and cloud computing.
  • Examples of documents to be authenticated using the proposed technology include certificates, transcripts, student identifications and can be extended to licenses, food and medicine certificates, insurance ID cards, reimbursement forms and many other document types.
  • Primary aim of the method is preventing the issuance of fraudulent documents and detection of any fraudulent document where fraud is committed after the issuance of a document.
  • the invention will both detect any alteration made after issuing the document and original electronic data on the authenticity server belonging to the organization.
