Efficient and secure data destruction ledger system
System Overview:
Distributed ledger system: The system uses immutable distributed ledger technology to provide data availability, integrity and processing visibility.
Data destruction support: The system supports efficient destruction of sensitive data while maintaining the immutability of the ledger.
Technical components:
Technical integration: The system combines technologies such as encryption, digital signatures, data structures, distributed storage, distributed ledger technology, and smart contracts.
Distributed ledger nodes: Nodes maintain distributed ledgers, execute smart contracts, and process transactions.
Data subject database: Stores data subject records and data subject keys for encryption and decryption of sensitive data.
Data destruction mechanism:
Destruction engine: The distributed ledger Oracle server contains a destruction engine that is responsible for processing deletion requests and destroying related data.
Delete request processing: Receive a deletion request containing a data subject identifier and delete the corresponding data subject record and data subject key from the data subject database.
Security assurance: The destruction process ensures that sensitive data becomes inaccessible in the distributed ledger system without destroying the integrity and availability of the ledger.
Data recovery mechanism:
Recovery request processing: The system supports restoring previously deleted data subject records to make them accessible again.
Recovery engine: The destruction engine also supports recovery operations by inserting previously deleted data subject records and data subject keys into the database.
Transaction processing process:
Encoding and decoding process: Transaction requests are processed by the encoding and decoding engine to ensure that sensitive data is encrypted during transmission and decrypted after processing.
Consensus mechanism: Use consensus protocols (such as PBFT) to reach consensus among distributed ledger nodes to ensure the validity of transactions and the consistency of ledgers.
Performance and efficiency:
Efficiency: The system ensures the efficiency of data destruction and recovery by optimizing the encoding and decoding process and using compression and encryption technologies.
Availability: Even when performing data destruction operations, the system maintains the availability and processing capabilities of unaffected data.
Application scenarios:
Sensitive data processing: The system is particularly suitable for industries that need to process sensitive data, such as finance and insurance, to ensure data compliance and privacy protection.
Regulatory compliance: Supports enterprises and organizations to comply with regulations such as GDPR and provides data deletion functions to meet requirements such as the "right to be forgotten".
What is the main function of the system?
The main function of the system is to provide a system and method that supports efficient and secure destruction of sensitive data in an immutable distributed ledger.
What key technologies does the system use?
The system combines multiple key technologies such as encryption, digital signatures, data structures, distributed storage, distributed ledger technology, and smart contracts.
How does the data destruction mechanism work?
The data destruction mechanism receives a deletion request containing a data subject identifier and deletes the corresponding data subject record and data subject key from the data subject database to ensure that sensitive data becomes inaccessible in the distributed ledger system.
How does the system ensure the security of data destruction?
The system processes deletion requests through the destruction engine to ensure that sensitive data is not leaked during the destruction process without destroying the integrity and availability of the ledger.
How is data recovery achieved?
The system supports the recovery of previously deleted data subject records, and reinserts the previously deleted data subject records and data subject keys into the database through the recovery engine to make them accessible again.
How does the system handle transaction requests?
The system processes transaction requests through the encoding and decoding engine, encrypts and decrypts sensitive data, and ensures the security of data transmission and processing. At the same time, consensus protocols are used to reach consensus among distributed ledger nodes to ensure the validity of transactions and the consistency of ledgers.
What are the application scenarios of the system?
The system is particularly suitable for industries that need to process sensitive data, such as finance and insurance, to help companies and organizations comply with regulatory requirements, such as GDPR, and provide data deletion functions to meet requirements such as the "right to be forgotten".
