Who wouldn’t want ownership and control over their identity?
Managing digital identities can help you interact online securely and with increased privacy. Data security is a big concern in current scenarios. We usually hear that tons of data get stolen and misused. The graph given from McAfee shows an increase in identity theft from 2017-2021.
Digital identities comprise attributes like personal info, affiliations, credentials, and permissions. This generates a need for Hyperledger Indy, an open-source project for decentralized identity management. It tackles issues of centralized control, privacy, and breaches in traditional identity systems.
Decentralized identity management uses blockchain for enhanced control and security. Decentralized systems use cryptography for users to prove identity attributes without overexposing personal info. This empowers users to manage their digital identities across platforms, reducing data breach risks and giving control over their online presence.
In this blog, we’ll discuss Hyperledger Indy’s role, components, and applications!
Hyperledger’s role in addressing identity vulnerabilities through blockchain technology is paramount. Hyperledger uses blockchain’s transparency, immutability, and decentralization for secure digital identity management.
Hyperledger is working in this field with its Hyperledger Indy project. It is a blockchain app that verifies your identity and ensures reliable connections. It has a blockchain as a root. Interoperable with other chains, it extends identity management to diverse networks.
Through Hyperledger’s projects like Indy, blockchain-based identity management offers:
Through blockchain, Hyperledger fortifies identity management, enhancing security, and granting individuals safer, privacy-focused digital identity control.
Now, let’s explore Hyperledger Indy’s crucial components and concepts for identity management.
1. Self-Sovereign Identity (SSI): Hyperledger Indy advances self-sovereign identity, granting individuals control over their digital identities. Users independently manage and share identity attributes, bypassing central authorities.
2. DIDs (Decentralized Identifiers): DIDs link identities, ensuring secure communication between users and service applications. DIDs are globally unique, cryptographically verified identifiers independent of central control. They enable secure interactions between entities while ensuring data privacy and ownership. Here’s an example of DID.
In practicality, DIDs are created for each relationship you have on the internet. Both sides of relationships provide a DID for the other to use to communicate with them.
3. Transcript: Transcript is a significant component within the Hyperledger Indy framework. It’s a verifiable credential with individual identity or attribute details. It represents a piece of information that is claimed to be true and can be digitally verified.
4. Agent and wallet: Hyperledger Indy uses agents and wallets for secure interactions between identities and verifiers. Agents act for the owner; wallets store keys, DIDs, and credentials.
5. Verifiable credentials (VCs): Verifiable credentials are digital claims by entities about themselves or others. These credentials can include attributes like age, education, or certifications. VCs are cryptographically signed, making them tamper-evident and allowing for easy verification. You can show these credentials whenever it is needed. VCs are cryptographically processed for certainty when proving claims to verifiers. The receiver can be certain of:
6. State and storage: In Hyperledger Indy the state is maintained by Patricia Trie. It is a combination of Merkle Tree and Radix Trie. The storage system uses leveldb for ordered mapping of value/key database.
In the current web2 scenario, centralized storage is susceptible to data corruption and hacks. This also makes that central entity the owner of the data. The central authority can use this data as per their convenience. Blockchain provides solutions to these issues.
Decentralization addresses the core problem of data corruption and central authority control. It gives ownership of data to the user to whom this data belongs and then this user can decide to whom he wants to share. A lot of data protection laws are imposed to solve this issue of data tampering and corruption.
Data protection laws stress transparency, accountability, and individual data control rights. They mandate robust security, informed consent, and data access, correction, or deletion options.
The government is enhancing data protection laws. Europe and the USA enforce stringent data protection laws for personal info and digital privacy. These laws demand strict guidelines on collecting, processing, storing, and sharing personal data
In Europe, the General Data Protection Regulation (GDPR) is a prime example of a robust data protection law. It allows individuals to have greater control over their personal data.
In the USA, laws like CCPA and HIPAA set rigorous data protection rules. They stress transparency, accountability, and individual data control. These laws demand robust security, consent, and data access options.
Below scenario explains how Hyperledger Indy works and provides solutions to identity issue.
I hope you understood the concept of the blockchain identity project: Hyperledger Indy. It aims to balance data-driven progress with safeguarding individual privacy rights.
