Kalp's Subnetwork Segmentation: A Solution for Data Privacy
Kalp's subnetwork segmentation feature provides a flexible, compliant, and privacy-focused solution to these challenges. By enabling subnetworks, Kalp empowers network participants to segregate data based on privacy needs and regulatory requirements. Here’s how Kalp addresses data privacy and compliance:
Private vs. Public Data Management: Using the Kalp SDK, subnetwork smart contract developers can choose which data to keep private and which to share on the public ledger. This segmentation enables organizations to protect sensitive data, such as PII, PHI, and PCI-related information, by storing it within the nodes of the sub-network but not on the public immutable ledger. In contrast, non-sensitive data that benefits from transparency can be made publicly available, supporting the ethos of decentralized transparency while respecting data privacy.
Compliance with GDPR: Kalp’s architecture allows subnetworks to comply with GDPR by enabling data to be stored privately, securely, and with the option for deletion if required. This granular control over data ensures that organizations operating in GDPR-governed regions can meet regulatory standards without sacrificing the benefits of blockchain technology.
Enhanced Security for PII, PHI, and PCI: Sensitive data, such as PII and PHI, can be isolated within specific subnetworks, protected by customizable access control mechanisms defined at the subnetwork level. This ensures that only authorized participants can access this data, maintaining compliance with standards like HIPAA or PCI DSS.
Jurisdictional Compliance: Kalp’s modular architecture allows subnetworks to enforce specific rules based on geographic jurisdictions, ensuring that each subnetwork adheres to local data privacy laws. This is a critical feature for organizations operating globally, where different countries have distinct data privacy requirements.
Blockchain Transparency Without Compromising Privacy: Unlike permissionless chains that cannot easily differentiate between public and private data, Kalp’s subnetwork approach offers the best of both worlds—blockchain transparency for public data and strict privacy controls for sensitive information. This makes it an ideal solution for industries like healthcare, finance, and supply chain, where data privacy is a top concern.
Right to Be Forgotten: In compliance with privacy regulations like GDPR, Kalp’s subnetworks provide the ability to fully delete private data stored within the subnet. When data is deleted, only the hash of this private data is retained on the public ledger, ensuring data integrity without compromising privacy. This means that the actual content of sensitive information is never stored on the public ledger, reducing the risk of unauthorized access while adhering to privacy laws. This capability grants organizations the flexibility to enforce the "Right to Be Forgotten," an essential aspect of modern data privacy.
