, Description:TECHNICAL FIELD OF INVENTION
This invention is related to managing online education system with the help of blockchain technology.
BACKGROUND OF THE INVENTION
“Education is the most powerful weapon you can use to change the world.” – Nelson Mandela
In past decades education was bound to school, colleges. Students have to go school, colleges for particular time to get education. In that era, all the education system is maintained by written ledger.
But as time changes, computer had arrived in the world. Then with use of computer it was going to easy to maintain the system in educational field. Then came internet, which changes the face of each and every field. Education filed also got affected by it very vastly.
Online education is also new trend came into picture due to internet. Due to rapid development in Internet technology, online education has entered into a stage of rapid growth. Online education is also known as online learning or distance education, which is web-based teaching method. It is fast learning using information technology and internet technology. Using internet as medium, online education transcends the limits on venue, environment, time and teachers. It offers students quality teaching activities anytime anywhere.
With immense popularity, the current form and systems of online education have many drawbacks due to increasingly open and digital internet. For example, many online courses provide certificates of online courses, that can be viewed by anyone because that system was centralized. That cause risk to students’ privacy. Students intellectual property cannot be maintained effectively due to the openness of the internet and temper ability of data.
To make learning process and results more trustable, it is necessary to develop a distributed and trustable data storage method to record the students learning process, disclose all learning data to public and ensure security and non-temper ability of data. Blockchain technology is most simply defined as a decentralized, distributed ledger that records the provenance of a digital asset.
The present invention is the solution of all above question.
OBJECTS OF INVENTION
The main object of the presented invention is that it is online education system achieved by using blockchain technology.
Another object of the presented invention is that privacy of student information is maintained.
Another object of the presented invention is that due to blockchain technology, it is distributed data architecture.
Other object of the presented invention is that data is stored on server in cryptographic form.
SUMMARY OF THE INVENTION
The present invention discloses, the online education system using blockchain technology. At backend blockchain server the students learning data, learning time, with marked timestamp is stored in cryptographical form. The student personal information also stored at backend blockchain server. As the student login to the system the stored information in distributed, immutable form will be shown to student. This information couldn’t be modified or deleted by anyone. The queries get answered by the application. As the course completed, the certificate is provided to student. The information about certificate is added to student’s data in block format.

DETAILED DESCRIPTION OF THE INVENTION
The present invention discloses a system for online education by using blockchain technology.
Blockchain is, in essence, a digital database (or ledger) distributed across a network of computers.
The records are protected by cryptography and are, therefore, protected against human error, editing and removal. The versatility of blockchain means it is being widely considered as a way to manage financial transactions, asset transfers and regulatory obligations.
Security, transparency, time and cost efficiencies are some of the reasons, for which blockchain has found applicable to online educational system.
The online education system with blockchain technology is comprising of contents such as,
Any Electronic computing device with active internet connection-
Students sign up and log in purpose.
Student learning purpose.
Application Interface for educational system-
Provide all learning course with timeline to student
provide certificate of completion of course to student
Backend server –
All student data, all course data is stored in cryptographically form with help of blockchain technology.

The system and method for aiding land registration by using blockchain technology is comprising of the steps are as;

Step 1) Backend blockchain server has fed with all data about all courses provided online in the form of blocks and these blocks are hash to blockchain.
Step 2) As student sign up for first time, all credentials are provided by student is stored on backend blockchain server.
Step 3) The student selects particular course by requesting to online application.
Step 4) The requested course is sent to student in the form of block which are in only view mode. No deletion or alteration is possible.
Step 5) Student ask queries if have, then answer will be provided to student by online application.
Step 6) After completion of course, student will be awarded with grades and certificates online, as smart contract be formed in between student and online institute.
Step 7) The record of grades and certificate obtained by student is stored in the form of block and hash to the blockchain in cryptographically form.
Step 8) Student can see all the course, grade and certificate he has earned.

Blockchain technology also be useful with regards to online certifications. Since any block added to the chain must be approved by other participants, the record cannot be falsified. This prevents people from creating fake certifications to say that they passed or excelled at a particular course. The records are also quite easily checked.
Blockchain technology represents a major part of human innovation and existence. We have only begun to scratch the service of what it can do for the advancement of society. Whole industries will be transformed, and the online education sector will be no different as blockchain provides added security in the sector.
There are some advantages of the blockchain technology in online education system, such as:
Decentralized eLearning platform - Blockchain offers the possibility of decentralized education platforms maintained by consensus rather than a central authority. It makes a truly peer-to-peer learning experience possible.
One startup creating a decentralized e-learning platform is LiveEdu, who are building on top of the Ethereum blockchain. LiveEdu connects content creators and learners, with a focus on content that focuses on real projects and not theoretical knowledge.
Securing Student Data - As educational establishments rely increasingly on Internet-accessible databases, the risk of a hacker changing their grades, adding unearned certifications or even deleting (or stealing) an entire database also increases. Blockchain solves this problem at a fundamental level: the technology requires consensus to confirm transactions, which become immutable once sufficiently confirmed. Since each full node maintains an independent copy of the blockchain and verifies it against all others, there are no central attack points. The cost of protecting student data falls while security improves.
Authenticating and Securing Certification - Confirming authenticity is easy with blockchain. Once an educator adds an individual’s certificate(s) to the ledger, the details not only become immutable but are publicly available and separated from the issuing establishment. Employers can simply reference the online record to verify a potential hire’s learning history.
