Cloud computing offers a high scalable environment for data outsourcing in the cloud. This allows a user to access all the cloud applications of any complexity, without thinking about the limitations of the local system infrastructure. It also provide medium to share the data among others. However originality and authenticity of data that is stored in cloud is an open challenge as it has large provision for data lose and date correction. In order to prevent the outsourced against various challenges, many tradition data auditing mechanism on employing third party auditor has been provided in the literatures with computation and communication capabilities. A portable data management system to will be able to perform auditing process, so that we can ensure the accuracy of the data which is stored on a unreliable third party server. This process is done without even, retrieving all the data. Despite of various advantage of public auditing, preserving the identity privacy from third party auditor has become vital task for the current research. In this paper, we have proposed a reliable and secure ring signature for preserving the privacy of data that is outsourced and shared, using public auditing in the computing paradigm. In this work, ring signature is exploited to privacy preserving of the data auditing of common outsourced data. Further the idea of ring-signatures has to be used to build the authenticator on each block of the data that is outsourced, while keeping maintaining the authenticity of the shared-data to be audited. Finally this model can support multi auditing task simultaneously. Experimental analysis on the proposed system proves that it is more secure and highly efficient against data based attacks. Evaluation the performance of the proposed model has been validated that it outperforms state of arts approaches on computation cost and time.

Now days the conflict takes place between human and elephant is one of the biggest issue throughout the world. In Tamilnadu the biggest elephant conflict arise in villages available near nilgris, muthumalai, etc. Most of the Asian and African countries has farm land, it gets affected by elephants. The crop land are affected by elephants it is one of the biggest issue throughout the world. There some traditional methods like use of fire crackers, drum beating, construction of elephant barriers, noise-making, fencing etc. are used so far. But these methods are not effective in all the situation to prevent the crop as well as human from elephants. The proposed system is more efficient and accurate than the other systems. The vibration sensor is used to detect the movement of elephant in forest border areas. The elephant is captured through camera. The animal is found out of camera zone it is detected through the sound produced by elephant. The captured image is send to database and the SMS is sent to nearby forest officers, crop field owner and also public people. The SURF algorithm is used to match the captured image with database. Likewise audio finger print algorithm is used to detect the algorithm through voice command. Here ZigBee is used to transmit the SMS to 25 meter around the forest areas.
