摘要：The system Passport Authentication Using PNG Image with Data Repair Capability introduces a passport authentication method for preventing the criminals and terrorists to travel between countries with fake or forged documentation. The more effort those countries, universities and other organizations put into verifying the identity of foreign nationals, the better the chance of keeping criminals and terrorists from entering a country and causing problems. The main aim of the proposed system is to design innovative system which deals with passport authorization management. The motto of the project is to develop a new and secure passport system and to simplify the job of the security people. In short, have a flawless passport verification system. In the proposed system, as first phase the stego image formation and as second phase, the verification stage, in this the authentication and self repairing are carried out. If part of a document image is verified to have been illicitly altered, the destroyed content can be repaired in the second phase. Such image content authentication and self-repair capabilities are useful for this security protection. In short the system proposes an authentication method that deals with binary like color docum ent images instead of binary, grayscale ones and simultaneously solves the problem of image tampering detect `ion and visual quality keeping.
