Abstract

These days, cloud computing is producing large volume of repository area and enormous parallel computing at adequate cost. Extreme volume of data is being reserved in the cloud since the cloud computing is becoming more popular. In spite of, the aggressive rise of growing amount of the data has erected mo re number of novel challenges. In this task, the issue with integrity auditing and the secure deduplication exist on cloud data is studied. Especially, the target is on gaining both the data integrity and deduplication which is existing in cloud, two secure systems is designed called SecCloud and SecCloud+. The SecCloud will offer an auditing stuff with the alimentation of a Map Reduce cloud that aid the clients in order to provoke the data tags before they are being uploaded as well as to audit the integrity of data that is being reserved in cloud.

Keywords

Cloud Computing, Secure Deduplication, Data Integrity.

Abstract

Environmental concerns have led to the need of sustainable use of natural resources. It is important to use natural bacterial population for environmental cleaner techniques. One of those strategies is biodegradation of natural or man made xenobiotic compounds. The present investigation is on isolation of hydrocarbon utilizing Pseudomonas from local red soil. The isolates were identified to species level by performing biochemical and physiological tests as P. aeruginosa, P. aureofaciens, P. putida and P. fluorescens. The isolates were screened for the utilization of petroleum hydrocarbon (kerosene) and the conditions (temp and pH) optimum for its utilization. The isolates were screened for their ability to utilize petroleum hydrocarbon (kerosene) as their sole source of carbon and energy. Biodegradation results revealed that, the highest growth was showed by P. putida followed by P. fluorescens, P. aureofaciens and P. aeruginosa. The results evidenced that, all the four isolates harbored two low molecular weight plasmids one with 3Kb and the other with 10kb to 12Kb.
