System and method of providing a secure inter-domain data management using blockchain technology

A method of providing a secure inter-domain data management using blockchain technology, the method comprises the steps of:

• (A) providing at least one group managed by at least one remote server, wherein the at least one group includes a plurality of member accounts, and wherein each member account is associated with a corresponding member personal computing (PC) device and includes a member access level;
• (B) providing at least one blockchain system, wherein the blockchain system is managed by a network of computing nodes;
• (C) providing a plurality of files stored on the network of computing nodes, wherein each file includes at least one file access level;
• (D) prompting each member account to select a specific file from the plurality of files through the corresponding member PC device;
• (E) comparing the member access level of an arbitrary member account to the file access level of the specific file with the network of computing nodes in order to grant access to a decryption key for the specific file to the arbitrary member account, if the specific file is selected by the arbitrary member account in step (D), wherein the arbitrary member account is any one of the plurality of member accounts;
• (F) relaying the decryption key for the specific file from the network of computing nodes, through the remote server, and to the corresponding member PC device of the arbitrary member account, if the member access level of the arbitrary member account is greater than or equal to the file access level of the specific file;
• (G) prompting the arbitrary member account to enter the decryption key for the specific file into the blockchain system with the corresponding member PC device;
• and
• (H) accessing the specific file with the corresponding member PC device of the arbitrary member account, if the decryption key for the specific file is entered into the blockchain system in step (G).
