Blockchain Method and Apparatus for Protecting Sensitive Data of Trading Activities

Glossary

Term Definitions Blockchain systems, also known as distributed ledger systems (DLS) or consensus systems, allow multiple parties to securely store and verify data. Smart Contracts Computer programs embedded in blockchains that are automatically executed when predefined conditions are met. Trading Activities Activities that utilize blockchains and smart contracts, such as promotions or marketing activities. Sensitive Data User information that needs to be protected, such as identity or contact information. Activity Data Information related to trading activities, such as the identity, expiration time, and budget of smart contracts. Digital Certificates Electronic documents issued by an authentication server to verify the authenticity of information or entities. Authentication Servers Trusted entities that issue and manage digital certificates. Accounts of Trading Activities Blockchain accounts associated with specific trading activities that are used to manage activity funds and execute transactions. Budgets Funds allocated to trading activities.

Answer

What are the advantages of blockchain systems in protecting trading activity data? Blockchain systems provide an immutable and transparent record of data. Once data is added to the blockchain, it cannot be changed, which ensures the integrity of the data. In addition, transactions on the blockchain are visible to all participants in the network, promoting transparency and accountability.

What role do smart contracts play in trading activities? Smart contracts automatically execute the terms and conditions agreed upon in trading activities. They act as a decentralized medium to ensure that transactions are executed when predefined conditions are met, without the need for intermediaries and reducing the risk of disputes.

What is sensitive data and why is it important to protect sensitive data in trading activities? Sensitive data refers to any information that may compromise an individual's privacy, such as name, address, or financial details. Protecting sensitive data in trading activities is critical because it prevents identity theft, fraud, and other privacy-related risks.

How do digital certificates play a role in protecting sensitive transaction data? Digital certificates help establish trust by verifying the identities of the parties involved in a transaction. They act as electronic credentials, confirming the identity of the user and ensuring that they are authorized to participate in the transaction.

What role does the authentication server play in blockchain-based transactions? The authentication server is responsible for issuing and verifying digital certificates. It acts as a trusted entity, confirming the identity of the individual or organization associated with the transaction.

How do transaction accounts differ from users' personal accounts? Accounts for transaction activities are dedicated to specific transactions and are associated with the smart contract to which they are associated. They are separate from users' personal accounts and do not contain any sensitive user information, thereby protecting user privacy.

What information does activity data typically contain? Activity data includes information related to the transaction, such as the identity of the smart contract, expiration time, budget, and transaction rules. It may also include details about the nature of the transaction, such as the goods or services provided.

How can the identity of the smart contract be used to protect sensitive transaction data? The identity of the smart contract can be used to protect sensitive data by associating the account of the transaction with the identity of the smart contract instead of the personal identity of the user. This association ensures transparency of the transaction while hiding the identity of the user from the public.

What are the benefits of setting the expiration time of digital certificates to the same expiration time as transaction activities? Synchronizing the expiration time of digital certificates with transaction activities prevents unauthorized use or misuse of certificates after the activity ends. It adds an extra layer of security and ensures that transactions are processed only within the validity period.

Describe how blockchain-based transaction activities can help maintain data transparency while protecting user privacy. Blockchain-based transaction activities promote transparency by recording transactions on a public and immutable ledger that is visible to all participants. However, by using the identity of the transaction activity's account and smart contracts, the user's sensitive data remains hidden, ensuring privacy and preventing information leakage.
