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.

How can public-key cryptography be leveraged to validate zero-knowledge proofs?

Posted on March 25, 2021 By Author

Introduction: the importance of data security and protection in this day and age.

Given that a bulk of communication today is conducted within the webspace, an essential requirement for anyone engaged in online exchanges becomes data protection. There is always a possibility that one’s private data can be acquired by unethical means and then used and manipulated to benefit fraudsters.

According to McKinsey,75 percent of experts across various industries view cyber risk to be a significant concern.

There is much concern about how data is exchanged and apprehension about third parties’ unquestioned acceptance to entrust them with personal information. Fortunately, now there is the technological possibility of systems that deal effectively with these worries by employing encryptions that strictly keep the exchanged data between the parties engaged in the process.

The necessity of leveraging public-key cryptography arises because of sensitive and private information on the internet and the urgent need to protect them from falling into the wrong hands.

The importance of zero-knowledge protocols.

Public-key encryption uses asymmetric keys to encrypt and decrypt messages to ensure cybersecurity. Asymmetrical encryption is considered better because it prevents a user’s private-key from being compromised and yet doesn’t hinder the receiver from successfully decrypting the message with the public-key they already have. This process of the zero-knowledge protocol transfers data and verifies reception and possession without putting the owners in danger as a target of unscrupulous external parties out there on the Internet. The process mentioned makes sure of the reception of particular knowledge without revealing the exact nature. Online communication is always in need of such validation of proofs.

Why is public-key cryptography used to validate proof?

There are several reasons to be mentioned as to why encryptions of this kind using similar technologies are essential:

1. A digitized database: Filing and documentation are universal requirements of all organisations, irrespective of nature, goal, or location. Traditional methods of creating a database can fall prey to human errors or, more dangerously, tampering people with the wrong intentions. The benefit of a database would be the fact that it organises and keeps necessary documentation without worrying about the compromise of accuracy, physical space-related issues, or even unlawful acquisition. 2. Minimum face to face interaction: Especially concerning current global problems and general currents of professional activity, interactive practices in person are becoming less and less customary. Using public-key encryption and zero-knowledge protocols makes it possible for data authentication and user verification work without actual human presence, thus creating a more vital case for safe online interaction. 3. Equal relationship between a server and the client: The unique feature of public-key encryption is that it demands authentication on both sides of the transaction. The client can leverage the server’s key for encryption, generating a secret key that can only be decrypted with the actual private-key. Again, the receiver can decrypt data with the help of the private-key only available to them. 4. Protection of sensitive documents, even in the absence of creators: Of course, the most important benefit and the primary purpose of public-key cryptography is to protect sensitive documents. When sending contractual papers, financial and legal documents, transaction details, one’s certificates, and even credit card applications, it is possible that the information generated by users can fall prey to fraudulent activity. With encryption that makes easy and straightforward validation attainable, it is possible to imagine a safe and secure exchange process. These technologies also work to protect very confidential and potentially high-value documents like wills and testaments. It ensures the safety and integrity of such papers even if the original creator is not present corporeally. 5. Easy to learn and use: One of the general requirements from software presently is that it be user-friendly. From the needs of different enterprises to regular communicators on the internet, it seems much better to control software one uses, into their own hands. Beyond the issues of privacy, third-party involvement also often renders the user dissatisfied and unsure. The verification process used by public-key cryptography is simple enough to be handled by non-expert users. People can quickly learn to use it, and it becomes an effortless part of daily activities. 6.Ideal for organisations of all sizes: The fact that such software is cost-efficient makes it more inviting for use. As mentioned before, data security and safe exchanges concern all users irrespective of their data’s scale and nature. Smaller organisations run into the same risks and find themselves unable to employ third parties or get stuck with traditional data protection methods that don’t guarantee a hundred percent efficiency. Therefore, such technology’s development is a welcome change in such smaller or newer organizations or individual communicators in cyberspace. 7. No third party involvement: Since most people are reluctant to involve third parties in their equation of exchange, public-key encryption can be used to create a reference point for verification on the untampered, immutable blockchain. This removes the need for third-party verification. It is reliable because it uses a unique hash value on the blockchain, as mentioned earlier, and this cannot be altered.

Conclusion

To find reliable software to guide the exchange processes taking place online is an essential engagement of all organisations functional today. Having the guarantee that what is sent over a particular network remains within that and doesn’t get tampered with is the primary concern.

ProofEasy, a beneficial product from RightCliq Solutions, uses similar technology to help people have safe transactions over the internet.
