Generally, the documents like academic certificates, Aadhar Card, PAN card and so on are very important in everyday life. For example, if the person is going for interview or admission; we have to carry these paper documents for verification and other purposes. As we are living in digital world, it can be replaced with the help of some software technologies. Now days, almost all the students are using smart mobiles. It is inevitable in this pandemic situation across the world. It becomes part and parcel of student’s community, especially college going students. Paper documents can be replaced with digital documents which is the main motto of this project. Also, if anyone loses the paper documents or drop them somewhere by mistake, they can be misused. Uploading them on servers is risky as it can be hacked. On the other hand, keeping them openly on our phones is not good either. Thus, this research is going to develop this app that will save the uploaded document in an encrypted form and store them in the Internal Memory, to avoid any kind of hacking. The data will be stored in the device using SQLite and for the front end and functioning; you can use the platform of Android Studio. The best thing about this system is that it is secured with Pin. This PIN is created by the users to access the file while registering them on the application. Secure pin will ensure the safety of the document even if the phone is with someone else. The files are secured in such a way that no intruder can access them in any case. The same work is developed as windows application which will be installed in some cloud server. The staff in-charge of certificate verification, He or she gets the PIN from the student and verifies the certificates with certificates which are saved in his or her smart mobile phone. At the same time, this research can check the authenticity of the students by using bio-metric system, that is, fingerprint system can be used. If everything is verified, then we can issue the certificates. Moreover, this research promotes authenticated person only can access this server.
