Cooperative storage cloud : ウィキペディア英語版
Cooperative storage cloud
A cooperative storage cloud is a decentralized model of networked online storage where data is stored on multiple computers (nodes), hosted by the participants cooperating in the cloud. The total storage contributed in aggregate must be equal to the amount consumed for the viability of the co-operative. However, some nodes may contribute less and some may contribute more. There may be reward models to compensate the nodes contributing more.
Unlike a traditional storage cloud, a cooperative does not employ dedicated servers for the actual storage of the data, thereby eliminating the need for a significant dedicated hardware investment. Each node in the cooperative runs specialized software which communicates with a centralized control and orchestration server, thereby allowing the node to both consume and contribute storage space to the cloud. The centralized control and orchestration server requires several orders of magnitude less resources (storage, compute and bandwidth) to operate relative to the overall capacity of the cooperative.
== Data security ==
Files hosted in the cloud are fragmented and encrypted before leaving the local machine. They are then distributed randomly using a load balancing and geo-distribution algorithm to other nodes in the cooperative. Users can add an additional layer of security and reduce storage space by compressing and encrypting files before they are copied to the cloud.
Symform generates and keeps the keys used to encrypt/decrypt, and since it also decides which server will host which piece you have to trust Symform not to share those with any other party or misuse it.〔http://virtualserverguy.com/blog/2012/12/19/symform-security-analysis〕
