Method of enforcing privacy based on All or Nothing Transform

摘要

PURPOSE: An AONT based privacy reinforcing method is provided to minimize data storage space and reinforce privacy through fragmentation by using XOR operation according to AONT property. CONSTITUTION: Information to be encoded is fragmented according to a fragmentation attribute. All attributes are divided into conversion pieces having variable size in an AONT(All-Or-Nothing Transform) mode. One conversion piece is stored in first database and the other conversion pieces are stored in second database. First and second database is security agent database and server database.
