Abstract
A system for trustlessly proving possession of secured data includes a storing device designed and configured to store a collection of data, divide the collection of data into a plurality of lots, receive a cryptographic accumulator of the collection of data, the cryptographic accumulator having a root and a plurality of accumulated elements, wherein each accumulated element is produced by performing an encryption process on each lot of the plurality of lots, evaluate a posting of the root to an immutable sequential listing, select an accumulated element as a function of the root and a public pseudorandom function, generate a secure proof of possession of a data lot used to produce the accumulated element and transmit the secure proof and the accumulated element.
