Document Storage And Retrieval System Using Aadhaar Number

Abstract

Aadhaar Number issued by UIDAI (Unique
Identification Authority of India) has many advantages. They
are used to create an authorized identity of individual by which
individuals can be identified. This identity can be useful in
applications of documents in banking, college, RTO’s, etc. Our
system is focused on storage of personal confidential
documents of individuals by which they can access it from
anywhere and at any time. To uniquely identify each
individual, we use Aadhaar number as a unique user ID for
everyone. User can be identified by their Aadhaar number as it
is a unique number for each individual. Document security is
provided using AES (Advanced Encryption Standard)
algorithm. Documents will be encrypted using the AES Image
Encryption Algorithm and stored. During document Retrieval
the encrypted documents are decrypted using the Decryption
Algorithm and then user can access them. User Validation is
done by sending OTP (One Time Password) to the user or by
providing a Biometric Scan of the user. Individuals documents
can be accessed by either providing the OTP received by the
user or by biometric scan of the user. At time of document
retrieval, users permission is needed for his/her document
access. This permission is given either by OTP or Biometric
Scan. The application of this system in real world environment
will reduce the paperwork related to documents in
Government sectors. The use of documents in a digital way will
reduce the maintainability and the effort of carrying the
documents everywhere.
