The concept of identity verification is emerging in various fields such as IT and blockchain. This term refers to verifying or proving the existence of a person’s personal information in order to participate in services, rights, or online activities. In today’s digital and online world, authentication is a fundamental challenge in many industries, including banking, online shopping, and even social networking. The importance of security and protection of personal data requires an identity verification mechanism that works securely and reliably.

What is the way to show the letter?

The personality proof mechanism as a new approach, through advanced technologies such as blockchain and digital identity technologies, allows people to verify their identity digitally. In this sense, Personality Proof benefits greatly from blockchain technology, which ensures the security and transparency of identity processes. One of the important features of the Personality Test is that it does not depend on centralized centers. In other words, this mechanism allows people to prove their identity without the need for intermediaries or central organizations. This feature gives people more control over their identity and personal information.

Overall, proof of identity represents an important development in security and identity assurance in the digital world, and it could have far-reaching implications for a variety of issues, including citizenship rights, health, as well as online economic activity. As per the advancement of technology and development process in this field, concepts and tools related to proof of personality can be updated.

Prove the identity of users through authentication mechanisms

Verifying the identity of users using a personal authentication method means that people can prove their identity digitally using various technologies, especially blockchain technology. This method allows people to securely and transparently confirm their identity without the need for intermediaries or central organizations. Below are some features and possible ways to verify your identity using personal authentication.

Blockchain technology: Because blockchain is a centralized and transparent data structure, it can ensure secure storage of identity information. Each person’s identity information is recorded as a record on the blockchain, and people are allowed to access that record.

Digital imagery or biometric information: Digital imagery or biometric information can be used as an identification factor in character proof mechanisms. Facial recognition technology or other biometric information may be used to verify a person’s identity.

Digital Identity Technology: The use of digital identity technology allows individuals to access private keys and verify their identity. A combination of encryption algorithms and digital signatures are used to create a valid digital identity.

Smart Contracts: Blockchain smart contracts can be used to define proof-of-identity conditions and automate the proof-of-identity process. These contracts evaluate the person’s identity based on specified conditions and, if successful, confirm the identity. Using these mechanisms, people can securely prove their identity and use various facilities and services without relying on centralized organizations. This approach can be used in a variety of industries, including banking, healthcare, and digital asset transfers.

Which projects use the role verification method?

The proof-of-personality mechanism has recently gained attention thanks to projects such as WorldCoin. Of course, proving a user’s character or humanity is not necessarily a new concept. In 2014, Vitalik Buterin spoke about the challenge of creating a “specific identity system”. In the system mentioned by the creator of Ethereum, a special token should have been issued to each person, which was considered an identification card and a document indicating the humanity of the user. Today, this system has become a character verification mechanism, and many projects are developing protocols based on it.

Proof of Personhood

Truth of the Cloud

The WorldCoin project has developed a system where users visit a device called the Orbe in person to register their iris scan. Thus, the identity of the user is confirmed and he is issued a global ID.


This project uses a captcha based game. In order to avoid double participation, the user must participate in the game at a certain time, which also includes creating a captcha to confirm other participants.

Identity card for you

BrightID users confirm each other’s identity through video calls with other users. Increasing the authentication level of users is also done through the Bitu system. In this system, the user’s identity is only confirmed if a sufficient number of users who have already been confirmed in Bitu confirm it.

Evidence of humanity

In this project you need to upload your video and deposit money, then for verification you need another user who wants a voucher and is given a trial period for a period of time. During this special period, other users may question the authenticity of your information. All disputes are handled in the Calross Virtual Court. Finally, if the video you uploaded is found to be fake or your profile is incorrect, your deposit will be forfeited and the person who challenged your profile will also receive the reward.

It will be delayed

To join the Circle, you only need a pre-approved user. Instead of issuing cards or tokens, this project’s identity proof method is based on a social graph where people’s credibility is determined from the perspective of their identity.


The project provides online (blockchain-based) and offline identity management services to businesses, regular users and developers. In effect, users who receive a Civic Pass will have a digital identity card that can be easily used in the world of Web 3 and DeFi.

Advantages and disadvantages of using the identity confirmation mechanism

Identity verification methods are used in different industries and each of them has its advantages and disadvantages. Some of the advantages and disadvantages of these mechanisms are listed below.


Information Security: Methods of proof of identity, especially in other security systems and blockchains, increase the assurance of data security and reliability.

Fraud reduction: Since identity verification is often done using complex algorithms, the chances of fraud and misuse of accounts are reduced.

Two-factor authentication: Identity proofing mechanisms such as two-factor authentication enhance login security. Even if one identity agent is attacked, the other agent maintains security.

Ease of access management: Using identity verification mechanisms to manage access to data and systems allows administrators to more accurately control access and permissions.

Proof of Personhood


Complexity: Some authentication mechanisms can be very complex and require in-depth training and understanding by users.

Cost: Implementing and maintaining complex evidence systems is expensive, especially when specialized equipment or complex infrastructure is required.

Privacy: Some identity verification mechanisms can inadvertently challenge users’ privacy, especially if they use biometric information.

Misuse: In some cases, users may misuse the identity verification mechanism, which may cause problems.

It is always important to consider the specific needs and parameters of each project in order to choose the most suitable identity verification system based on your situation.
