Abstract

A method for secure data sharing includes creating uniform resource identifiers associated with a dataset. The method also includes generating and storing data access permissions for the dataset in an immutable decentralized ledger with a distributed ledger technology, creating a metadata describing the dataset and enabling access to the metadata via uniform resource identifiers, receiving a request from a client device to access a data subset associated with the dataset, verifying a digital credential of the client device using a secure authentication method, authorizing the request and confirming that the client device has a permission to access the dataset based on the distributed ledger technology, and providing multiple instructions and keys to the client device to access and retrieve the data subset. A system including a memory storing instructions and a processor configured to execute the instructions to cause the system to perform the above method are also provided.

A computer-implemented method, comprising:

creating a uniform resource identifier associated with a dataset;
generating and storing a data access permission for the dataset in an immutable decentralized ledger with a distributed ledger technology;
creating a metadata describing the dataset and enabling access to the metadata via the uniform resource identifier;
receiving a request from a client device to access a data subset associated with the dataset;

5 more elements

A system that includes protocols, standards, processes, and systems, operating over a decentralized network, comprising:

a data sharing engine, including:
a one or more distributed ledger technology nodes linked with nodes of data sharing engines installed by other participants to form a decentralized network;
a directory tool that interacts with the one or more distributed ledger technology nodes to manage digital identities, authorizes a one or more data access requests, creates and updates a data point and their metadata, and manages a data point catalog;
a scalable data storage that is used to keep a dataset associated with the data point;
an encryption tool configured to generate encryption keys, encrypt data before storing them and decrypt it after retrieving data from the scalable data storage;
an access tool configured to receive a request from a client device to access the data point, authenticate the client device, and validate permission to access the data;
a request management tool configured to receive data from the client device and to store it in the scalable data storage;
a request management tool configured to retrieve data from the scalable data storage and send it to the client device;
and
a website engine that interacts with the data sharing engine to enable clients to operate the system using a web browser.
