Blockchain technology can help secure identity data in a number of ways, including:

• Immutability: Once data is stored on a blockchain, it cannot be changed or deleted. This makes it much more difficult for hackers to steal or modify identity information.
• Transparency: All transactions on a blockchain are publicly visible. This means that anyone can verify the authenticity of identity data and see if it has been tampered with.
• Decentralization: Blockchain networks are not controlled by any single entity. This makes them more resistant to cyberattacks and makes it more difficult for hackers to target identity data.

In addition to securing identity data, blockchain technology can also help improve the security of the information security triad, which consists of confidentiality, integrity, and availability.

• Confidentiality: Blockchain can help protect confidentiality by encrypting data and using digital signatures to authenticate users. This makes it more difficult for unauthorized individuals to access sensitive data.
• Integrity: Blockchain can help ensure the integrity of data by creating a tamper-proof record of transactions. This makes it more difficult for hackers to modify or delete data without being detected.
• Availability: Blockchain can help ensure the availability of data by distributing it across a network of nodes. This makes it more difficult for hackers to take down a system and prevent users from accessing their data.

Overall, blockchain technology has the potential to significantly improve the security of identity data and the information security triad. However, it is important to note that blockchain is not a silver bullet. It is still important to implement other security measures, such as strong passwords and two-factor authentication, to protect identity data.

Here are some specific examples of how blockchain is being used to secure identity data and improve the information security triad:

• Self-sovereign identity: Self-sovereign identity (SSI) is a blockchain-based system that allows individuals to control their own identity data. This means that individuals can share their identity information with only the parties that need it, and they can revoke access to their data at any time. SSI has the potential to significantly reduce identity fraud and improve the privacy of individuals.
• Supply chain management: Blockchain is being used to track the movement of goods and materials in supply chains. This can help to prevent counterfeit products and ensure that goods are not being diverted to unauthorized channels. Blockchain can also help to improve the traceability of products, which can be helpful in the event of a product recall.
• Healthcare: Blockchain is being used to store and share medical records. This can help to improve the efficiency of healthcare delivery and ensure that patients have access to their own medical records. Blockchain can also help to protect the privacy of medical records.

Blockchain enables more secure management and storage of digital identities by providing unified, interoperable, and tamper-proof infrastructure with key benefits to enterprises, users, and IoT management systems. With blockchain technology, information about identity is auditable, traceable and verifiable in just seconds. Individuals can curate their own profiles and control data sharing. Issuers easily connect with others and provide nearly instant verification of credentials. Each user who registers on the blockchain identity management system will get a unique identity number. The user's unique ID number consists of all personally identifiable information in an encrypted format stored on their device backed by IPFS. Blockchain-based authentication system helps verify the user's identity, helping to prevent identity theft. It ensures the tamperproof security of the digital ID of a person. The blockchain network is created based on a request for authentication and permission. Using a decentralized and immutable ledger, there is no need for a central trust authority to verify and validate transactions. So how does blockchain impact Information Security's CIA-triad? Integrity since all data stored as transactions in the blocks are signed, it provides a high level of integrity protection. Blockchain technology provides a secure and transparent way to record and transfer data. Its decentralized nature, encryption, transparency, immutability, and smart contracts all contribute to resolving data privacy and security issues for businesses.

Integrity since all data stored as transactions in the blocks are signed, it provides a high level of integrity protection. Confidentiality, Integrity, and Accountability, commonly called CIA Triad, are critical principles in cybersecurity. These principles help to ensure that data and systems are protected from unauthorized access, alteration, and misuse. Blockchain technology digitizes and distributes record-keeping across a network, so transaction verification processes no longer rely on a single central institution. Blockchains are always distributed but vary widely in permissions, sizes, roles, transparency, and types of participants and how transactions are processed.

For IoT safety, the blockchain is able to monitor the information collected by the sensors, without allowing them to be duplicated by any wrong data. Sensors can also transfer data using Blockchain technology, without the need for a trusted third party.
