DATA PROTECTION SYSTEM, METHOD, AND COMPUTER READABLE RECORDING MEDIA RECORDED AN PROGRAM

摘要

A data protection system, a method and a computer readable recording media recorded program are provided to generate partition data at a very high speed by using only exclusive or operation for making a signed partition data. A data protection system includes a data protecting unit(20), and the data protecting unit includes a data partitioning unit(26), a sign assigning unit(28), a distribution preserving unit(30) and a decoding unit(32). The data partitioning unit divides data which should be protected into n block data. The sign assigning unit generates signed data m according to pre-determined redundancy Q. The distribution preserving unit stores the m generated signed data distributed in a network storage connected through network. The decoding unit decodes the original data collecting more than k signed data among distributed and preserved m signed data.
