A “Media Sharer” operates within peer-to-peer (P2P) networks to provide a dynamic peer-driven system for streaming high quality multimedia content, such as a video-on-demand (VoD) service, to participating peers while minimizing server bandwidth requirements. In general, the Media Sharer provides a peer-assisted framework wherein participating peers assist the server in delivering on-demand media content to other peers. Participating peers cooperate to provide at least the same quality media delivery service as a pure server-client media distribution. However, given this peer cooperation, many more peers can be served with relatively little increase in server bandwidth requirements. Further, each peer limits its assistance to redistributing only portions of the media content that it also receiving. Peer upload bandwidth for redistribution is determined as a function of surplus peer upload capacity and content need of neighboring peers, with earlier arriving peers uploading content to later arriving peers.

A content distribution method and system for distributing content over a peer-to-peer network such that the full potential throughput of the network is achieved. The content distribution method divides the content to be distributed into many small blocks. Each of the content blocks then is assigned to a node, which can be a content-requesting node, a non-content-requesting node or a source node. Content is assigned based on a capacity of the node, where nodes having a larger capacity are assigned a greater number of content blocks and nodes having a smaller capacity are assigned a fewer content blocks. The capacity generally is defined as the upload bandwidth of the node. Redistribution queues are employed to control the throughput of the distribution. This bandwidth control strategy ensures that upload bandwidths of the peer and source nodes are fully utilized even with network anomalies such as packet losses and delivery jitters.

The embodiment of the invention discloses a cloud storage data method. The method comprises: a first server receives a file uploading request sent by a client, according to a first digital fingerprint therein, a second digital fingerprint of a first file is calculated, a block chain database is inquired according to the second digital fingerprint, and if it is determined that the block chain database stores the second digital fingerprint of the first file, the user ownership of the first file is directly recorded, and the client is indicated not to upload the first file. The block chain database can store second digital fingerprints of the files in a plurality of servers, the block chain database is inquired to determine whether the servers store the first files or not, if there are the first files, users do not need to perform upload again so as to allow the servers not to store repetitive files, effectively avoid the problem that the data stored in the cloud storage is subjected to duplication eliminating processing to cause that there is a lot of calculated amount and save the uploading bandwidth and the uploading time of users.

The invention relates to a mobile Internet data transmission and storage method. A client transmits data which needs to be uploaded to a storage cloud system. The storage cloud system carries out identification and encryption to each information. When needing the information, the other client sends a request to the storage cloud system and sends a verification code. After receiving the relevant information and performing the verification, the storage cloud system sends the relevant information to a user. The cloud computing safety architecture has the following advantages: for a video file, a recipient can perform playback without storing the whole file; the storage cloud system is used to receive the file, receive a demand of the playback and then receive the file; many times, the recipient does not play the whole video; for an image and a photo, if the recipient does not have an enough space, other parts of the file can be eliminated; after the file is stored in cloud, if the same file is sent to other friends, uploading bandwidth is not consumed any more; a file name needs to be transmit so that a server can push the file to the recipient.
