Data access control for edge devices using a cryptographic hash

A non-transitory computer readable medium storing instructions that, when executed by at least one processor of a first node in a secured network, cause the at least one processor to perform a data access method comprising:

• transmitting, to a second node in the secured network, one or more characteristics of at least one of a user device with which the first node is associated or the first node;
• receiving, from the second node, a request to execute a first test script of a plurality of test scripts, wherein at least one of the user device or the first node is selected for execution of the first test script based on the transmitted one or more characteristics of at least one of the user device or the first node;
• executing or causing the user device to execute the first test script to generate one or more first test script results;
• generating a first cryptographic hash of a blockchain for the one or more first test script results by performing one or more authorized modifications of first data of the blockchain;
• and
• transmitting the first cryptographic hash to the second node and causing the second node to verify the one or more first test script results based on the first cryptographic hash generated by the first node and a second cryptographic hash received from a first one or more other nodes in the secured network executing the first test script, the first one or more other nodes sharing at least some of the one or more characteristics with at least one of the user device or the first node.

• receiving, from a second node in a secured network, one or more characteristics of a user device associated with the second node;
• receiving, from a third node, a request to execute a first test script of a plurality of test scripts on at least one of the second node or the user device, wherein at least one of the user device or the second node is selected for executing the first test script based on the received one or more characteristics of at least one of the user device or the second node;

• receiving a second cryptographic hash from the second node, the second cryptographic hash generated in response to execution of the first test script;
• verifying the one or more first test script results based on the first cryptographic hash and the second cryptographic hash;
• and
• transmitting the verification and the one or more first test script results to the third node.
