Maritime blockchain platform GSBN (Global Shipping Business Network) has chosen to partner with Decentriq, for the latter to provide data privacy technology to its blockchain consortium, says an article published on Safety 4 sea.
Data clean room
Decentriq data clean rooms have been designed to address this problem and are found complementary to the blockchain.
In short, the Decentriq data clean room leverages a technology called confidential computing, providing an execution environment at the hardware level, which no one has access to.
While the GSBN Blockchain platform provides a tamper-proof record of the hashes of the encrypted data being submitted in the clean room, Decentriq is able to guarantee secure and confidential processing of sensitive data even when it’s off-chain.
In addition, the Decentriq platform allows for granular settings in the input, output, and permission.
This introduces another layer of access control policy, which can be configured based on both roles and scenarios.
The settings are viewable by all data contributors before submitting data to the clean room and agreed upon by all participants before the data clean room is published.
Usage is restricted
Once it’s published, the settings cannot be changed without the data contributor’s approval and all actions are logged so usage is restricted and monitored.
By combining blockchain and Decentriq data clean room, GSBN can guarantee not only data integrity but also privacy, security and auditability during the whole usage is restricted data lifecycle : at rest, in transit, and in use whether on-chain or off-chain.
GSBN is currently developing use cases with Decentriq such as the sharing of shipping activity insights from multiple shipping lines with financial institutions.
“We believe the next generation of blockchain consortiums will combine blockchain technology with other emerging technologies, such as confidential computing, enabling the aggregation of data from different sources and converting them into valuable insights while keeping them safe and secure”
said Edmund To, CTO of GSBN.
