Data Integrity Using Blockchain with case studies
- 2. Mechanisms to protect change of historical records, or at least to detect when someone is trying to do so Usually contains financial transactions Is replicated across a number of systems in almost real-time Can be read by participants, often a wider audience Uses cryptography and digital signatures to prove identity, authenticity and enforce read/write access rights Can be written by everyone in a public blockchain (but only certain participants in a private blockchain) What is Blockchain? Blockchain is more than a technology… © 2021 IBM Corporation Block 2 Block 3 Block 4 Block 1 hash hash hash hash
- 3. BLOCKCHAIN TECHNOLOGY Blockchain is a digital ledger technology Distributed - Records transactions across multiple computers Immutable - Registered transactions cannot be altered retroactively Transparency: Participants on the blockchain have access to the same ledger versions, providing visibility to the ledger. Technology underpins cryptocurrencies like Bitcoin and Ethereum which are popular among people
- 4. BLOCKCHAIN TECHNOLOGY 1. Distributed Ledger are shared records 2. Decentralized and does not have a Central Authority 3. Immutable and hence cannot change the history 4. Cryptographically Secure with encryptions and integrity assurance 5. Smart Contract which is an automated agreement between the involving parties
- 5. TYPES OF BLOCKCHAIN Low performance Scalability issue Anonymous Limited privacy & confidentiality Storage constraint Unsustainable consensus mechanisms Lack of governance and standards Not suitable for Enterprises where privacy and confidential is needed Public blockchain Private blockchain Restricts who can access and do what on the network Participants must be identified/identifiable Network is permissioned High transaction throughput performance Low latency of transaction confirmation Privacy and confidentiality of transactions Decentralized within the involved parties Governance is enabled
- 7. IMPACT OF BLOCKCHAIN INTEGRATION IN VARIOUS USECASES
- 8. KEY INDUSTRIES THAT UTILIZE THIS TECH BLOCKCHAIN NOW IN INDIA Secure Transaction Enhanced Transparency HEALTHCARE SUPPLYCHAIN FINANCE Protecting Patient Data Integrity in Clinical Trials Ensuring Authenticity Efficiency and Transparency GOVERNANCE Transparent and accountable record-keeping
- 9. What can be the major use cases for Government ? Government Public Utilities Logistics and Supply Chain Healthcare Finance Records management
- 10. IBM Institute for Business Value Financial Transactions • Retail consumers and utilities can benefit from timely and secure payments Energy Generation and Distribution • Highly regulated by Federal and regional organizations Renewable Energy • Blockchain “Renewable Energy Credit” tokens • One platform to track calculations of carbon emissions Infra Management • Detailed tracking • High-levels security for complex service delivery infra • Blockchain- integrated automated metering infra to gain real- time usage data Public Utilities © 2021 IBM Corporation
- 11. IBM Institute for Business Value Perfect geo location to serve as a logistics hub • Within 600 miles of 54% of US population • CVG airport is the 8th largest cargo hub (Amazon + DHL) Blockchain can provide: • Advanced communication flows between untrusted parties • Paired with other technologies, increased data access and reliability • Reduces costly errors, decreases delivery time, lowers overall costs Logistics & Supply Chain
- 12. IBM Institute for Business Value Healthcare Data Analytics • Track outbreaks across locations • Identify outbreak hot spots, speed containment response time, track community spread of disease Medical Research • Commonwealth: home to leading healthcare research institutions • Blockchain opportunities act as a draw healthcare business within state Controlled Substances • Add efficiency and security with National data sharing capabilities
- 13. IBM Institute for Business Value Empowers business and trade with highly secure and attestable financial transactions Improves currency conversion and clearing houses, increasing speed and efficiency Bringing about the “Digital Dollar” Finance: Digital Currency
- 14. IBM Institute for Business Value Physical signatures → Digital Signatures (DocuSign) • Lack of security and trust in the signer Blockchain Smart Contracts: • Validation of the signer using private keys • Increased security with decentralization • Automate process Records Management: Contracts Traditional Contract Smart Contract
- 16. HOW BLOCKCHAIN WORKS? Decentralization ◦ No Central Authority ◦ Resilience to Attacks Consensus Mechanisms ◦ Validation of Transactions (PoS, PoW etc.) ◦ Democratization of Operations Smart Contracts ◦ Automated Agreements ◦ Versatility
- 17. WHAT IS DATA INTEGRITY? Data is a valuable asset, ensuring its integrity is paramount Any compromise to data integrity can lead to severe consequences, including financial losses and damaged reputation Refers to the accuracy and reliability of data over its entire lifecycle
- 18. BLOCKCHAIN FOR DATA INTEGRITY Blockchain technology plays a pivotal role in preserving data integrity. Its cryptographic algorithms secure data and once information is added to the blockchain, it becomes virtually impossible to alter. Decentralization ensures that no single entity has control over the data, enhancing transparency and trust.
- 19. BLOCKCHAIN FOR DATA INTEGRITY Hash Identifications To ensure data integrity Proof of Work To ensure immutability in transactions Digital Signature Authenticated and untampered data is assured
- 20. BLOCKCHAIN INTEGRATION ROCESS FOR DATA INTEGRITY
- 21. BLOCKCHAIN BASED ARCHITECTURE FOR DATA SHARING Data owner requests keys to do encryption with Authorization center Data owner encrypts data using this key and store in IPFS and the Hash value of this Encrypted file is computed. The same is sent as a transaction to the Blockchain with the data records data and storage data Data owner who has received the keys to retrieve the file retrieve the Hash Values from the Blockchain and then download the data ciphertext which points to the data records and initiate decryption
