What is Web3?  

The concept of Web3 is often attributed to British computer scientist Tim Berners-Lee's 1998 proposal to describe a semantic web, which aims to make the web more comprehensible to machines and provide smarter services to users. In recent years, with the rapid development of blockchain technology, the era of Web3 has been gradually approaching.

Web3 aims to create a more decentralized and secure internet by designing new technical protocols and building new infrastructures, allowing users to have control over their digital identities and digital assets.

The importance of Web3 in the digital world is reflected in the following aspects:  

• User-Data Control: Users own and manage their own data, no longer relying on centralized service providers.  
• Transparency: Blockchain technology provides transparent transaction records, enhancing user trust in the platform.  
• Decentralized Finance (DeFi): Provides financial services without intermediaries, granting users greater financial autonomy.

Web3 Data Privacy Challenges

The emergence of Web3 signifies a new era emphasizing decentralized technology, user empowerment, and the critical importance of digital identity and privacy. However, with these advancements come several challenges, particularly concerning privacy issues related to personal information protection and data security. On one hand, personal information and data have become vital foundational elements and strategic resources on a global scale; on the other hand, security issues arising from data leaks and the flow of personal information cannot be overlooked. It is essential to understand the significance of personal information within the Web3.

When discussing personal information, two key terms inevitably come to mind: Personal Information and Sensitive Personal Information.

• Personal Information refers to any information that can identify an individual, directly or indirectly. This includes details like names, email addresses, phone numbers, and physical addresses. It is essential for a person's digital identity and is often collected by online services for account creation, marketing, and analytics.
• Sensitive Personal Information, however, is a specific type of personal information that could cause harm or distress if exposed. This includes data such as medical records, financial information, Social Security numbers, and biometric data (like fingerprints or facial recognition). Because of the serious risks associated with its exposure, sensitive personal information requires stronger protection and is usually governed by stricter regulations.

As the "next generation of the internet," Web3 revolves around the core principles of decentralization and user sovereignty. In the Web3 architecture, users have the autonomy to control their personal data and digital identities, which represents a significant advantage and distinction from Web2. Therefore, the protection of personal information is of paramount importance in the Web3 landscape.

Privacy Issues in Web3

In the decentralized environment of Web3, data privacy issues are particularly significant, encompassing multiple dimensions and having a substantial impact on user security and finances. Here are some common data privacy issues:

1. Privacy Breaches Due to Transparency: In many blockchain networks, the records of transactions and activities are public, allowing anyone to see addresses, transaction amounts, and timestamps. While this transparency enhances trust, it may also lead to the inference of users' personal information. For example, if a wallet address is linked to a user's identity, transaction history, or other data, an attacker could identify the user by analyzing these transaction records.

2. Complexity of Identity Management: While Web3 promotes decentralized identities, users face complexities in managing these identities. Many users lack the necessary technical knowledge to effectively set up and secure their digital identities, which may lead to the exposure of their personal data during use.

3. Data Misuse and Surveillance: Although Web3 aims to provide users with greater control, some decentralized applications may still collect and use user data without sufficient transparency. This data collection could be used for inappropriate purposes, leaving users unaware of and unable to control the usage of their own data.

Despite these challenges, innovative solutions are facilitating broader adoption. For instance, zkMe addresses these issues by providing user-friendly, privacy-focused tools that comply with regulatory standards while ensuring data security and interoperability.

zkMe: Revolutionizing Privacy Control in Web3

As a decentralized identity infrastructure, zkMe provides secure and private identity verification within the Web3 ecosystem. It uses zero-knowledge proofs (ZKP) to enable users to verify their identity without disclosing any sensitive information, offering a truly private and decentralized identity solution.

zkMe empowers users and businesses with a revolutionary approach to digital identity in the Web3.

Advantages of zkMe in Privacy Protection:  

• Self-Sovereign Identity: Credential holders have full control over all data sharing, including anonymous information.  
• End-to-End Zero-Knowledge: All personal data processing is fully automated and takes place directly on the user's device or a decentralized oracle network. During due diligence, regulators, companies, third-party data processors, or even zkMe cannot access any personal identity information.  
• Selective Disclosure: Personal information is only shared when necessary, and only in response to predefined demographic questions with yes/no answers.

The zkMe network uses advanced technologies such as cryptography, blockchain, and artificial intelligence to ensure the security and privacy of personal data, for example, through zkMe’s zkKYC and zkMe DID.

• zkKYC

zkKYC is a solution that allows Web3 businesses to comply with regulations while preserving decentralization and customer data privacy. By utilizing zero-knowledge proofs, it verifies user identities without disclosing sensitive information, enabling compliance with global KYC requirements in the least intrusive manner.

zkKYC effectively addresses the data privacy issues associated with traditional KYC processes. First, it emphasizes personal data protection by using zero-knowledge proofs (ZKP), allowing users to verify specific attributes without disclosing any raw data. This approach not only protects user privacy but also ensures that users have full control over their data, reflecting the decentralized and user-sovereign principles of Web3. 

Additionally, zkKYC offers reusability, allowing users to reuse previously collected KYC data across multiple services and institutions, simplifying the identity verification process. This method improves the user experience by eliminating the need to repeatedly submit personal information, enabling users to verify once and access multiple partnered services. 

zkKYC also addresses regulatory compliance by enabling users to prove their adherence to KYC/AML requirements without revealing personal details to service providers. Finally, it allows users to reclaim and migrate their data if issues arise with a system or service provider, enhancing trust and control over digital identities.

• zkMe DID

zkMe DID uses CKKS Homomorphic Encryption technology to create facial DIDs. "One Face, One DID," ensuring that each user has a unique DID. Homomorphic encryption technology allows calculations to be performed on data in an encrypted state, which can prevent sensitive data from being exposed in plaintext. At the same time, liveness verification technology can prevent malicious users from uploading photos of others to register fake accounts. 

Users can easily access zkMe to create privacy-focused identities. When a user (Credential Holder) creates a DID using zkMe, they are issued a unique Soul Bound Token (SBT) that is cryptographically linked to their public key. An SBT is a specific type of token that represents a user's identity within a blockchain network and can be verified by other parties in the network.

How Does zkMe Help Users?

zkMe utilizes zero-knowledge proofs (ZKP) to enable secure and private credential issuance and verification, helping users manage their personal data more cautiously and securely:

• Data Sovereignty: Users have full control over their personal data on zkMe. By creating a decentralized identity, users can selectively share relevant information without disclosing their complete personal data. This ensures that users decide what information is shared in any interaction, protecting their privacy.
• ZKP Technology: zkMe employs zero-knowledge proof (ZKP) technology, enabling users to verify their qualifications or attributes without revealing personal identity information. For instance, users can prove they meet certain requirements (like age or nationality) without disclosing specific identity details. 
• Secure Identity Verification: By creating a zkMe DID, users can achieve secure identity verification across multiple platforms and services. This security is powered by encryption protocols that ensure personal data remains confidential and is not misused during the verification process.
• Transparency and Traceability: zkMe provides transparent permission management, allowing users to track who view their sharing history. This transparency empowers users to manage and monitor their data effectively.
