Information Dispersal Algorithm
It is an implementation of Information Dispersal Algorithm.
In short Information Dispersal Algorithm (IDA) breaks a file F of length L = |F| into n pieces Fi , 1 ≤ i ≤ n, each of length |Fi| = L/m, n > m so that every m pieces suffice for reconstructing F. It has vast area application, can be used to provide data redundacy protection against unauthorized access.
