Abstract
A method of redundantly encoding data includes formatting the data into columns and rows, and generating first and second sets of projections of the data using an encoding transform. For each set of projections generated, an encoding parameter of the encoding transform is set to a different value. The first and second sets of projections are stored as the encoded data. A decoding method reads settings including an indication of a number of data fragments. The number of data fragments is compared to a number of projections in a first set of projections of the encoded data in order to determine whether to use a first or a second decoding mode. The encoded data is then decoded according to the selected decoding mode and the result is outputted.
