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.
