Abstract
An apparatus for generating encoded data includes processing circuitry configured to encode data using a Mojette transform (MT) based on generating encoded representations of data blocks. Generating the encoded representations of data blocks includes reading data in the form of a data block formatted according to specified settings to comprise rows and columns, creating a set of projections, and outputting the created set of projections to enable storage of the data in the form of the set of projections. The apparatus then transmits the encoded data over a network to another device. Additionally, creating the set of projections includes applying the Mojette transform on the data block, and creating a first number of projections based on mapping each row of the data block to a corresponding projection, wherein the first number of projections carries the same information as a corresponding row.
