Abstract
Today organizations face a challenge while recruiting candidates, who provide forged mark sheets in order to get a job. To prevent wrong hiring a detailed and thorough approach is needed to verify the authentication of both the candidate and the marks obtained by him/her. There are so many modern cryptographic protocols available which can be used for authenticating individual’s academic achievement certificates. Visual Cryptography is a simple and secure way to allow the secret sharing of images without any cryptographic computations or the use of encryption or decryption keys. The novelty of the visual secret sharing scheme is in its decryption process where human visual system (HVS) is employed for decryption of secret shares. In this paper we have discussed (3, 3) visual cryptography scheme which can be used to generate shares and distributes them among three parties, i.e. the Job Seeker, Certificate Issuance Authority and the Organization conducting Job interview. Secret message can be decrypted only if all the three shares are available. Every certificate carries a unique number which is encrypted using visual cryptography and without handshaking of all the parties it is impossible to decrypt, thus ensuring full proof authentication.
Highlights
Utilizing Visual Cryptography(VC) 3 shares will be created from this certificate no.,one of which(Share 1)will consistently be kept at Issuing Organization's hand,another one(Share 2) will be imprinted on the Marksheet and the last one (Share3) will be given to the up-and-comer or occupation searcher as Authentication Key
A novel certificate no.(associated with that mark sheet no.) is produced which will convey the imprints got as the suffix
Share 1 is kept at issuing association's end, share 2 will be imprinted on the mark sheet of the jobseeker, share 3 will be given to the activity searcher as an authentication key
Summary
Producing fabricated Marksheet to recruiting bodies by jobseeker has transformed into a noteworthy issue. For distinguishing forged mark sheet we will incorporate 3 shares of a Certificate no.(kept verified uniquely at Certificate Issuing Body's end) and will appoint these shares to (Share 1)Certificate issuing Organization,(Share 2)Printed on Marksheet,(Share 3)candidates as an Authentication Key. The candidate or the job seeker is producing the original certificate just if in the wake of consolidating all these 3 shares the unscrambled picture matches with the first Certificate No. From the start, the certificate issuing organization creates the Marksheet with mark sheet no imprinted on it. Utilizing Visual Cryptography(VC) 3 shares will be created from this certificate no.,one of which(Share 1)will consistently be kept at Issuing Organization's hand,another one(Share 2) will be imprinted on the Marksheet and the last one (Share3) will be given to the up-and-comer or occupation searcher as Authentication Key. Presently during the confirmation procedure of the jobseeker, the person in question will produce the mark sheet no and the authentication key to the recruiting body.
