Abstract
A first data handling node () is configured to verify data received in a data distribution network with multiple data handling nodes forming a distribution path of a network topology, by obtaining tag information from a hash server (). The first data handling node () receives data (D) and a hash tag (H) from a second data handling node (). The received data (D) and hash tag (H) have been generated by the second node based on a previous hash tag (H, H) generated by a preceding third data handling node (). The third node has delivered data (D, D) to the second node, and the received data (D) has been generated by the second node based on the data (D, D) delivered by the third data handling node. The first data handling node () verifies the received data (D) based on the tag information from the hash server, which indicates whether the received hash tag (H) corresponds to a 'valid hash tag' (Hx) which is calculated by applying a predefined hash algorithm on the previous hash tag (H, H). When the received tag corresponds to the valid tag, the data is verified as trustworthy and not faked or manipulated.
