Abstract (en)
[origin: WO2020146448A1] A computer-implemented method for content-agnostic referencing of a binary data file, the method comprising: pregenerating a table of all permutations of data of a particular length, determining a length of the binary data file, the length comprising the number of bits of the binary data file; chunking the binary data into chunks of data of a smaller length; for each chunk, determining if the chunk is in the pregenerated table, and if so using that chunks index in the pregenerated table, and otherwise chunking the data again until the sub-chunks are located in the pregenerated table, and using the number of chunks and associated indices to indicate the binary data file.
