Abstract

A data tracking method, which is performed by a data tracking apparatus in an edge cloud environment including at least one edge node communicating with an end device and a central cloud, includes receiving data from the end device by a first edge node, creating, by the first edge node, a tracing history and distributing the data to a plurality of edge nodes so as to allow the plurality of edge nodes to create tracing histories, transmitting the created tracing histories to the central cloud by the first edge node and the plurality of edge nodes, and verifying, by the central cloud, linkability of the tracing histories transmitted to the central cloud, storing the tracing histories, analyzing the tracing histories, and providing a data tracking function.

Claims6

Dependent claims

A data tracking method performed in an edge cloud environment including a plurality of edge nodes each communicating with an end device and a central cloud, the data tracking method comprising:

receiving, by a first edge node, data from the end device, creating, a tracing history for the data to transmit to the central cloud, and generating a copy of the data to distribute to at least one edge node determined according to a data distribution policy determined by the central cloud;
receiving, by the at least one edge node, the copy of the data and creating a tracing history for the copy of the data to transmit to the central cloud;
receiving, by the central cloud, the tracing history for the copy of the data and verifying linkability of the tracing histories to store the tracing histories;
and
analyzing, by the central cloud, stored tracing histories to provide a data tracking function based on the stored tracing histories,
wherein the data distribution policy comprises a policy for selecting the at least one edge node in which the copy of the data is to be stored in consideration of storage spaces, activation states, and data processing speeds of the edge nodes and a tag of the data.

3 more elements

In an edge cloud environment including a plurality of edge nodes each communicating with an end device and a central cloud, a data tracking apparatus implemented in the central cloud comprising:

a processor;
and
a memory storing at least one command to be executed by the processor,
wherein the at least one command is configured to cause the processor to:
determine a data distribution policy to be used by the plurality of edge nodes for distributing a copy of data and provide the data distribution policy to the plurality of edge nodes;
receive a tracing history for data from a first edge node receiving the data from the end device, creating the tracing history for the data, and generating a copy of the data to distribute to at least one edge node determined according to the data distribution policy;
receive a tracing history for the copy of the data from the at least one edge node receiving the copy of the data and verify linkability of the tracing histories to store the tracing histories;
and
analyze stored tracing histories to provide a data tracking function based on the stored tracing histories,
wherein the data distribution policy comprises a policy for selecting the at least one edge node in which the copy of the data is to be stored in consideration of storage spaces, activation states, and data processing speeds of the edge nodes and a tag of the data.
