Abstract

Abstract:According to the educational statistics there are about one million graduatestudents in one year. Due to lack of effective anti-forge    mechanism, causes the certificates to beforged .To solve this digital certificates system using public keyinfrastructure is proposed. Public Key Infrastructure (PKI) is used for thesecure communication in the network. Digital certificates need to validate veryquickly and securely. For this PKI is used for security.  As per the current popular validation    system, it delivers the validationinformation to the client’s .Due to which clients system suffers from highoverhead. Motivated by this observations we present the effective validationsystem. Our implementation of the Certificate Validation System using QR Codeis able to validate the digital certificate in short period of time and in lowcost. It also provides security of the user’s documents. QR Code is basicallyused for accessing the documents easily and a database is also provided in oursystem to store the data of the student in it.
