Management of Classified Information for Information Dispersion Technology
Kentaro Ishibashi, Kazuaki Tanaka · 2011
In recent years, we treat various electronic documents in a computer. This makes reuse and redistribution convenient. However, the information on electronic data has risks. We propose the technology of dividing information safely and managing it for avoiding of this problem. This technology is designed based on the algorithm of mathematical information division. The features of this technology are conditions which restore the divided information. For example, original information is divided into N blocks. The divided block required in order to restore this information is M pieces (M≥N). It is impossible to restore the original information in less than M blocks. This technology is realized by M-1 degree equation. Original information is intercept of the equation, and N number points one the equation are divided data. We program this technology, and implement the application which put together this technology and AES[1] (AES: Advanced Encryption Standard).
