Abstract:The situation in India about road accidents is a serious problem. The State and Central government have been implementing measures to prevent the accidents on road by making helmets compulsory for two wheelers, speed limits, banning drivers from using mobile phones,etc. But if the accident occurs there is no provision for the victims to get the medical assistance immediately. So, accidents are the considerable economic losses to victims, their families, and to countries as a whole. To help the victims of road side accidents an android application will be developed. The witness of an accident can help the victim by just sending the image of that accident spot to nearby hospital or ambulance and nearby police station for further inquiry. A provision can also be made in future to get the identity of the victim to inform his/her relatives, this can either be done by matching the captured image of the victim with Aadhar card linked database or by bio-metrics. The main goal behind the development of our app will be to save the victim's life, as soon as any witness have noted the accident spot or whoever had notice such an incident.

Cloud computing allows network access to a computing resources like servers, storage and applications. These shared resources can be increasingly use-full to the consumers on the basis of paying only for resources they use. Cloud provides the delivery of storage resources to the consumers over the Internet. Private cloud storage is to a particular organization and data security risks is more in cloud. Hence, private cloud storage is built by using the commodity machines within the organization and the important data is stored in it. When the use of cloud increases the problems also increase like performance & storage demand, privacy & security, data integrity. Increase in storage leads to extend the cloud storage with more storage nodes. During such expansion, the storage on the cloud needs to be managed In order to maintain the load across storage nodes, the data need to be move across the storage nodes. This data that is moved from one location to other, consumes more network bandwidth. The key idea behind this is to develop a dynamic load balancing algorithm based on de-duplication to balance the load across the storage nodes during the Extension of private cloud storage. For maintaining privacy, security & data integrity we will use AES algorithm & SHA algorithm. SHA algorithm also used to avoid duplication.
