Abstract— A QR code is a quick response code. To access
information present in a QR code, we have to scan it by using
any type of scanner in order to get stored information. Data
is not safe in the system[1] where there is a need for instant
sharing of files in a limited time. To overcome problems, in
this paper we present JWT (JSON Web Token) Token for Qr
generation and to validate whether a user OTP(One Time
Password) system is implemented. JSON Web Token creates
a JSON object that is used to transfer information between a
client and a server on the web. After generating a QR code
we can scan with the help of any device that has a QR
scanner as a medium. After scanning the user will get the
information about the particular Users & will be able to
download their basic documents in different formats. We
have used NodeJS to develop the user interface that contains
libraries to generate QR codes. This system guarantees the
safety of documents as we used JWT and OTP two
authentication methods.

1. INTRODUCTION
Our primary objective is to create QR codes by which
the users will be able to view or download all of their
documents in different text formats. After generating a QR
code we can scan with the help of any device that has a QR
scanner as a medium. Bar codes are machine-readable tags
attached to items that have information related to that
detail. Nowadays, the QR Codes are mostly used due to
their high reliability and space as compared to barcodes.
In QR code the information is mainly stored in formats
such as number, alphabet & binary, etc.
QR code, in Fig.1 is scanned by a scanning device, like a
camera or scanner, and formatted algorithmically by
underlying package till the image is fully understood.
information is then discharged from patterns given in each
horizontal and vertical part of the image severally. The QR
characteristics are listed in table 1. The figure shows a
sample of an encrypted QR code used by the proposed
system.
QR codes are helpful to users in sending information. QR
codes are reliable and have high space. QR can store any
kind of data. A QR code is a tag that can only be read by
scanner and contains the data related to the product.
Fig. 1 Structure of QR Code
In above Fig.1, the QR code format is clarified in a
detailed way. The QR code design comprises different
design patterns like arrangement design, position design,
rendition data, timing example, and calm zone. Position
designs recognize the place of the QR code. An alignment
pattern design assists with the change when QR code size
is surpassing the cutoff. Timing design pattern , which is
addressed by spotted lines, is utilized to decide the size of
the information framework. The configuration data locales
contain blunder remedy techniques. Whenever QR code
size is enormous then alignment pattern designs assist
with direction. Different adaptations of QR codes are
involved and translation in Fig.1 distinguishes the form of
the QR code. The quiet zone is utilized for the end scanning
purpose. Shortcoming amendment pieces are put away in
the variant data. Real information is available in data and
error resolving bits. QR code has some unique attributes
that are as follows-
• QR code can organize different types of data.
• It stores data in a small space.
• The QR code can be restored if any malpractice occurs.

Fig 2. Capacity, characteristic, and Norms for QR Code
Our system can be merged with the platform used by
the institute or it can be made as a separate platform. The
following points will describe the tasks of our system.
Our system performs the following tasks:
● Insert information and documents
● System creates QR Codes
● Runs Identity check
● Scan and download the documents
including the user’s information
In this paper, we will explain about existing systems,
their challenges, and lastly our proposed system.
2. RELATED APPROACHES/WORK
In this section the existing system is studied actually,
the QR codes are created for storing data and also for fast
reading applications like payment apps, shopping
referrals, product descriptions and registration etc. In
Paper[2] two storage level QR code is used for document
authentication which mainly contains 2 levels as private
storage and Public Storage. Public Storage level is standard
QR code which can be accessed by anyone but private
storage level having encoding Of data with error
correction. Due to this it is easy to differentiate the original
document from the copy one. So there are some drawbacks
in this system also. In paper[3] document generation and
authentication mechanism is introduced in which the
VSS(visual secret sharing) algorithm is used. This
algorithm divides the image into two parts and encodes it
into two different QR codes. From that share1, one QR
code is used for sharing and printing on identity
documents, whereas the share2 stores in database. By
using scanner If we scan the share1 QR code,
It authenticates with share2 QR code from the database
and generates the desired document. System is a little bit
confusing and difficult to maintain two QR codes for a
single document.
Fig. 3. Detailed QR code structure
Related approaches contain the work other author’s
have done previously. Existing systems have used QR code
as their primary part in their systems in various ways. We
will highlight some of the systems that have used QR code
along with other features that profoundly contain
document sharing. Document verification through QR code
has been the simplest system among them all and it uses 2
level QR code for the purpose [4]. It uses QR code as an
encryption method for document sharing only. Another
system that implements the concept of QR code for image
storing and retrieval purposes has been specifically related
to the medical field [5]. It uses API for authentication and
JSON format to store image and data and whenever needed
the DICOM image can be retrieved with the use of QR code.
As mentioned above, it only deals with the DICOM image of
the patient and stores his image in a database. It uses APIs
for authentication of the patient while retrieving the
patient’s DICOM image. One more system that deals with
the implementation of QR code can be highlighted here.
File sharing system [1] deals with the working of QR code
that contains files encrypted within itself. Thus, QR code
along with the encrypted file can be shared to any user
that needs the file at the moment. It consists only of
encryption that is present in the QR code and not any other
frameworks and token systems that we have implemented
in our system. Data and files are stored in the QR code by
using the benefits of QR code’s encryption only. They do
not have any other encryption methods that are active and
working for their system.

3. CHALLENGES FACED IN EXISTING SYSTEM
● Instead of 2D QR codes they are implemented
dynamic QR codes
● Only image retrieval using QR code is present in
the existing system.
● Multiple algorithms had made the system complex
to run.
● Dedicated storage increases budget.
● Existing system has implemented various
techniques only for text storing into the QR code.
It has a missing concept of document storage and
retrieval.
4. THE PROPOSED SYSTEM
QR codes are systematically used to store and
download the private information and documents
alongside the General information because of high
authentication and security. We proposed a separate
concept to enhance the security of the website using the
JWT authentication. To use the system, the user registers
himself into the system and stores all his documents and
other personal details in the dashboard of the particular
user. On the basis of those details, the system will generate
QR codes respective to the user base of the system. Then
the user will be able to scan and download the documents
using authentication. When a user sends his/her
information to the system, as shown in Figure 6 in
response, the system will send the QR code to the user.
Fig 4. System Architecture
Getting access to the required document with QR code
is the cheapest and most adaptable option among all of the
solutions. With the automatic generation of JWT tokens,
cheating can be avoided.
This is the unique system in which if a user wants to
generate their own QR code which contains the all-basic
details in text format and the link of all soft copies of the
document, then they have to register with the system. In
other scenarios, if a user wants to download and access the
details of the other user by scanning their QR code, the
user need not have registered. Even if you're not the
registered user of the System you are able to download the
document. For Authentication users need to provide valid
credentials so that the document misused cannot be done.
In this system we use the JWT authentication process as
well as OTP.
Fig 5. Home Dashboard
In Fig (5) Dashboard allows the user to upload his/her
documents. The user needs to 1st signup by entering their
basic details such as username and password. After
successful registration, users are now able to access their
account by providing login credentials. On the server side
These details are then verified and along with this JWT
token is generated by the server. Session then redirects the
user to the web page where they can upload all their
documents which can be stored on the share Drive and
also generate the QR code if the user clicks on the
generated QR code the new web page will be opened
where. Fig 6 shows the form where Users can fill up All
basic details like name, age, birthdate, address, phone
number, email address along with the social media IDs like
Facebook and Instagram etc. After filling all the details the
user needs to click on the submit in order to generate his
QR code. This QR code can be stored and downloaded by
the user for further use. If the user has this QR code then
there is no need to carry the hard copy of all documents
every time. Just carry the QR code which can be printed on
the ID card.

Fig 6. QR Code Generation
After generating QR code, users can now share the
generated QR Code which is shown in fig.6 with anyone
who wants their details. Suppose if a user is an external
user who has not registered with the system, they can scan
this QR code. After scanning the QR code, they will be
redirected to the page where all basic details are shown
along with the link of the storage drive where documents
are stored. After clicking on download, the system fetches
the respective user’s access code. Which is the JWT token
said by the owner of the QR code generator for accessing
details.
Fig 7. User generated QR Code
After generating the qr code, it gets authenticated via
the auth code. Users are then redirected to the document
dashboard where they can download the documents after
validation of the OTP. Once the validation gets done it
redirects to the shared drive portal which contains
students/person's personal information as well as his
documents. Each user gets a size of 500mb to store their
documents. Those documents should be in any form like
.pdf, .jpg, .jpeg, .png, .docx, .txt, .xls, etc.

5. CONCLUSION
Getting access to the specified document with QR code
is the cheapest and most adaptable option among all of the
solutions. It doesn't require infrastructure changes to
adapt to that. With the recognition of the smartphone and
internet accessibility, it is often widely utilized in
universities. With the automated generation of JWT
tokens, cheating is avoided. Because the Technologies still
grow, the requirement for QR codes will diminish.
