US 11,240,020 B2 · Techniques for securing and controlling access to data

Abstract

Various embodiments are directed to techniques for controlling access to data in a decentralized manner. An apparatus includes an apportioning component to divide an item of data into multiple portions based on an organizational structure of the item of data; a tree component to generate a PRN tree including a multitude of nodes and a branching structure based on the organizational structure, the multitude including at least one branching node and multiple leaf nodes that correspond to the multiple portions; a PRN component to generate a PRN for each node of the multitude, the PRN component to use a PRN of a branching node of the PRN tree to generate a PRN for a leaf node that depends therefrom; and a communications component to transmit the multiple portions and multiple addresses based on PRNs of leaf nodes of the PRN tree to a server. Other embodiments are described and claimed.

Claims22

Dependent claims

An apparatus, comprising:

a processor;
and
memory comprising instructions that when executed by the processor cause the processor to:
identify a first pseudo random number (PRN) associated with a first node of a first PRN tree, the first PRN received pursuant to a first read access request associated with a first portion of data, and the first portion of the data associated with the first node of the first PRN tree;
determine an address for the first portion of the data based on the first PRN;
and
access, at the address, the first portion of the data responsive to the read access request.

4 more elements

At least one non-transitory computer-readable medium comprising a set of instructions that, in response to being executed by a processor circuit, cause the processor circuit to:

identify a first pseudo random number (PRN) associated with a first node of a first PRN tree, the first PRN received pursuant a first read access request associated with a first portion of data, and the first portion of the data associated with the first node of the first PRN tree;
determine an address for the first portion of the data based on the first PRN;
and
access, at the address, the first portion of the data responsive to the read access request.
