Abstract
A method for encoding a block of data to allow it to be stored or transmitted correctly in the face of accidental or deliberate modifications, the method including constructing a number n greater than one of original components, each of which is derived from the block and each of which is smaller than the block, and combining original components to construct a number m greater than one of new components, wherein each of the new components is smaller than the sum of the sizes of the original components combined to produce it, wherein the block can be reconstructed from any set of n different components selected from the original components and new components, and wherein a set of n different components selected from the original components and new components contains more redundant information about the block than the set of n original components.
