Systems and methods for secure data exchange and data tampering prevention. A secure data system receives electronic data files from data entities and stores the files in a first storage. Each file includes data values collected by a respective data entity over a predefined time period. A benchmark system determines plural randomized snapshot times corresponding to the predefined time period. A data mapping is created between the first storage and plural second storage, based on the snapshot times and the number of files. Data values samples in each file are selectively transferred from the first storage to the plural second storage according to the data mapping. Each second storage stores samples synthesized from among the data entities associated with a single respective snapshot time. A benchmark data value is determined based on the synthetized samples stored in the plural second storage associated with the snapshot times.
