Abstract
Embodiments described herein are directed to generating a tree-based data structure representative of a data set and the verification thereof. As each data item of a data set is updated, a leaf node is generated that stores a hash value therefor. For every even leaf node generated, a parent node storing a hash value based on the hash values of its child nodes is generated. For each level of the tree, the hash value of the last odd node generated therefor is maintained. The foregoing process is performed recursively at each level of the tree. During verification, a new root hash value is determined for a new tree-based data structure generated for the data set to be verified. The old and new root hash values are compared. If the hash values do not match, a remediation is performed to restore the data set.
