Methods, systems, and apparatus, including computer programs encoded on computer storage media, for validating data authenticity. One of the methods includes retrieving data that includes (i) an archived version of a data source, (ii) a first hash value, and (iii) a set of provenance data for the archived version of the data source; hashing the archived version of the data source to generate a second hash value; determining that the second hash value and the first hash value satisfy a similarity criterion; detecting one or more differences between archived data in the archived version of the data source and current data in a current version of the data source; determining, using the set of provenance data, whether the archived version of the data source is likely authentic; and in response, restoring one or more portions of the data source corresponding to some of the one or more differences.
