摘要:In cloud computing, cloud user’s sensitive data is in the control of a third part, where cloud users feel there is no privacy and security of the data. But an economic choice is to use cloud computing and cloud storage instead of manage data center by itself. The difficulty is how to ensure their data is safe in cloud storage. In this paper, we present a framework to ensure Data security in cloud storage system. And we discuss several technologies to make the data is stored in cloud safe. The main goal of this paper is to design and implement a secured system against Server hijacking. This system uses more than one port for providing security. But only one port will be fixed for one customer at a time. When the user hits a wrong port is recorded and all its future requests are dropped. Thus this system acts as an Intrusion Detection System (IDS). Moreover, the UDP/TCP port number used by the server is different for different users and a shared secret between the server and the client. This mechanism simplifies both the detection and it does not require any change to existing protocols. This port switching technique is compatible with the UDP and TCP protocols. This system can be implemented in real time successfully. Now this paper proposed a new policy to encrypt the data by using UNICODE and Colours (supported by computer). This paper introduces a new technique for protecting the distribution of data by digital images through UNICODE and colours in universe (supported by computer).
