How useful it is to issue digital certificates on the blockchain?

Blog content:

Blockchain technology is used in several ways in varied industries for offering high-security managing distribution systems and recording valuable information. Blockchain records all transactions without any verification from third parties. An evolving issue in recent years is - counterfeiting certification. It is posing serious threats to people. Issuing paper-based certificates manually is prone to errors and time- consuming. Day by day, the number of people's data is increasing, so deploying a system for both issuing and verifying digital certificates based on blockchain technology can solve issues of forged documents.

What is the current problem with document certification?

Many organisations and businesses need original documents for verification purposes before further processing. Some valuable documents like (birth certificates) exist only once. Parties involved in verification and issuing other certificates may experience hesitancy to handle these sensitive documents and that can result in damage or even loss. Many parties are unable to protect the valuable physical pieces of paper with this process. Another big problem comes from data theft. Many people have reported it. So the question comes: how can this issue be solved? Creating digital proof or digital certificates certified or signed by respective institutions or authorised organisations can be beneficial. With blockchain-based digital certificates, you can access and verify the digital asset's authenticity without depending on any intermediary or third party. Traditional data records like paper files deteriorate over time. storing records like digital certificates on the blockchain can help in safeguarding sensitive credentials from destruction & damage. Blockchain document security methods can help users seamlessly secure their sensitive documents.

What about blockchain solutions?

Blockchain technology has brought a revolution in storing and sharing data. The mechanism of cryptography helps in keeping information fully secured. Blockchain offers a digital ledger or decentralised database of data. Centred on computer networks that approve updates before data get recorded and verified. It lessens the reliance and vulnerability of centralised data storage. Instead of handling physical pieces of documents, issuing and storing digital certificates in blockchain can be advantageous to users. You can efficiently utilise the benefits of blockchain, like - authentication, encryption and decentralisation. Every certificate consists of references of both issuer and receiver with a hash (a sign of document), that is stored in the public database. It is identical in the number of computers throughout the globe. These digital certificates with blockchain technology have vital additional advantages over any other certificates.

How does blockchain make digital certificates work?

When a digital certificate is issued, data gets digitised. A digital identity gets assigned to every certificate. All of the digital certificates are tagged as well as traceable. Original documents are stored safely in the computer networks in the blockchain which are known as nodes. In totality, blockchain makes digital certificates highly transparent and secured. It also makes it easy to unfurl any fraud because this technology can expose any forged or outdated certificates.

Are these digital certificates tamper-proof?

Yes, the digital certificates are tamper-proof not by just signing but right after the beginning of the transaction. A signing algorithm produces a signature that is encrypted through a private key. The digital signature in these certificates can never be forged without having access to the private key of the user or members. With the help of document security QR codes, users can secure their valuable credentials.

What are the potential benefits of issuing digital certificates on the blockchain?

Blockchain has evolved to be beneficial for the financial industry. This technology is the most talked about and sought-after technology used in the world. There are innumerable benefits of issuing digital certificates on the blockchain. Some of them are here: a) Require fewer resources for issuance: Issuance and maintenance of digital certificates on the blockchain require a very less number of resources. As a result, the whole process saves time, effort and human capital. b) Digital certificates are conveyable: Contrary to physical certificates, the digital ones issued on the blockchain need not be carried around every place. Digital certificates are there to exist for a lifetime. These certificates can be easily accessed on any of your devices from any part of the world. c) Ideal as Identity proof: Digital certificates based on blockchain are the best substitution for the traditional proofs of paper identification. Digital certificates are issued on a highly secured framework of blockchain which is fully secured. These verifiable certificates can be easily traced all the way back to an issuer. This method makes the procedure transparent. You can use the blockchain document security method for securing and storing your valuable documents. d) Gives overall data security: Paper certificates can also take days and months to get issued and dispatched. Paper certificates can be altered without issuing the institute's knowledge and that is risky. Digital certificates issued on the blockchain can not be altered by any person. If someone tries to tamper with it, then verification will fail. This makes data in your digital certificates fully secured as well as traceable. e) No third party requirement: Blockchain verification of digital certificates can be performed by any person having access to the network. There is no need for any third party interference for verification. Digital certificates can be verified even if any organisation that issued them no longer exists. f) For micro-credentialing: Every data remains encrypted in the digital certificates issued on the blockchain. Organisations or businesses can issue "micro-credentialing" for recognizing, career skills, learning and so on. It can help both students and organisations. g) Comes at an affordable cost: Using blockchain is not expensive. With the help of the blockchain-powered platform, you can issue digital certificates for numerous services with ease. You may need no extra software or hardware and be done with an internet connection. So in nutshell, the unique features of blockchain technology make issuing digital certificates easy and tamper-proof. Blockchain technology simplifies and facilities the entire process of issuance of digital certificates. It also helps in the easy transfer of these certificates leading to the expansion of contents and information. We hope in the next few years, more and more organisations will come forward in embracing digital certificates issuance on the blockchain. A blockchain document security system can help you to secure sensitive credentials with ease.

Everything You Should Know About a QR Code: How is Blockchain Encrypted QR Code Different?

Posted on April 1, 2022

Qr code means quick response code. A Japanese automotive company Denso Wave developed it in 1994. It works somewhat similar to a barcode, but it is much faster as it proceeds the information in a couple of seconds.
Contrary to a barcode reader that one needs to read information embedded in barcodes, QR codes do not need specials devices, and one can access it by a smartphone camera. One can use a QR code in many ways, such as to show product details, track overall product delivery, track the documents, to show menu to customers in hotels/restaurants, for accessing social media platforms, to get access to any webinar or any website or link, and even to transfer money etc.

Blockchain-Based QR Codes

Experts are making blockchain-encrypted QR codes in their sectors to bring a better level of security and safety. Over the last decade, you might have seen QR codes grow in popularity across different applications away from their original uses in manufacturing, thanks to the massive ownership of camera smartphones with applications that could read the QR codes.

It headed to an explosion of its utility – in marketing, secure documents, and more. In the last year, it steeply further in popularity because of its use for contract tracing for covid-19 and is presently omnipresent.

During the same decade, blockchain technology has also risen in popularity for possible uses beyond its initial use in cryptocurrency bitcoin. Now professionals are looking at it actively for smart contracts, trade finance, education documents, and the medical field. In addition, they are talking about using it to secure confidential documents like certificates.

Blockchain-Based Secure QR codes

You can consider a blockchain secure QR code because it is tamper-proof and secure on the blockchain, just like the immutable ledger. Being a validator user, you can still validate the documents or data even if you are not part of the network, which is the need in the blockchain. The point is that verification is decentralized in the blockchain. Thus, secure QR codes combine the utmost of both worlds for you.

For example, you can quickly secure your confidential documents and data in a secure QR code. Once you put a secure QR code on any record or data, one can access it only if the hash value of the code matches with the hash value of the secure QR code on the blockchain network. Hence, there is no room for any tampering or fraud. One can quickly validate the documents and stay at peace. For your understanding, the prime elements of blockchain are like:

– Better security: it is with the use of hashing, encryption and cryptography
– Distributed ledger: each participant can see every transaction and validate and even keep a copy
– Immutability: one cannot change or alter anything in an unauthorized manner
– Decentralised: there is no one governing authority
– It is based on consensus procedures.

The Bottom Line

Blockchain technology is expanding, and secure QR codes permit you to use them in different use cases such as cheques, invoices, id cards, passports, school certificates, trade finance documents, vaccination certificates, covid19 test reports, etc. If you want to integrate QR code security into your business procedures and documents, you can talk to experts at ProofEasy.
