A Algorithm for Safety Storing Data
Gu Jian · Hainan Daxue xuebao. Ziran kexue ban · 2001
In a system,how the very important data should be safely and reliably stored is a key question that all information systems must process,and it is a very good data storing method to devide the important data into groups and to store it in different nodes,and to take it from some stored nodes for making up the whole data when needing.This method makes the important data in a system unavailable without outhorized by a system,i.e.,when a few data stored in parts of nodes are obtained,it can't make up the complete data; and when some stored nodes are destroyed,the data stored in a system are still undisturbed.
