Image steganography, which is the art of hiding secret data within the images, can be performed using different software tools available. These software tools use different steganography algorithms to perform the operation. Steganography hides the fact that the communication is taking place by hiding the secret data within a carrier file whereas cryptography is a technique that encrypts the secret data during communication. Steganography along with cryptography is more secured data hiding technique and is thus used in many software tools. The paper aims at comparing the properties of the stego image of a carrier file produced from different tools. The steganography methods are experimented and their results are analyzed. Different measures of the stego images such as peak signal to noise ratio, mean squared error etc. are compared and are graphically represented. Thus the pa...

Recent studies have shown that ensuring load balancing (LB) in different data centre is critical for achieving optimal resource utilisation, maximise throughput, minimum response time and avoid overloading of resource. The traditional techniques of LB are not suitable for the cloud data centre's because of the virtualisation of the physical systems. In a centralised approach, scalability issues are more especially on machines with small amount of memory. On the other hand, a fully distributed approach tends to yield a poor performance on very large number of systems. In this paper, we propose a hybrid agent-based LB algorithm for cloud computing using Bees algorithm and queuing theory for Infrastructure as a Service platform. The proposed algorithm solves the problem of load unbalance and ensures high resource utilisation with minimum response time.

The exponential growth of cloud computing services in the last few years has resulted in extensive use, especially in storing and sharing the data on various cloud servers. The current trend in the cloud shows that the cloud owners use relative functions and target areas in such a way that cloud customers access or store their data either in the same servers or related servers. Simultaneously, from the security point of view, the lack of confidence about the customer's data on the cloud server is still questionable. The hour's need is to provide the cloud service in a 'single port way' by forming the joint management policy to increase customer satisfaction and profitability. In addition to this, the authentication steps also need to be improvised. This paper discusses issues on the security authentication and access provisioning of the cloud service consumers in federated clouds using subscribed user identity. This work proposes the user identity verification module (UidVM) in the cloud service consumer's authentication process to serve as a cloud broker to minimize the work overloads on the central cloud federation management system, thus enhancing the cloud security.

Hadoop bunch is worked for running information intensive distributed applications. Hadoop distributed file system is the essential stockpiling territory for BigData. MapReduce is a model to total undertakings of a job. Task assignment is conceivable by schedulers. Schedulers ensure the reasonable assignment of assets among clients. At the point when a client presents a job, it will move to a job queue. From the job queue, job will be divided into tasks and distributed to various nodes. By the correct assignment of tasks, job finish time will decrease. This can guarantee better execution of the job. This paper gives the comparison of different Hadoop Job Schedulers.

Internet users depend daily on SSL/HTPS for secure communication on internet. Over the years, many attacks on the certificate trust model it uses have been evolved. Mutual SSL authentication shared verification alludes to two parties validating each other through checking the digital certificate so that both sides are guaranteed of the other’s identity. In technical terms, it alludes to a client (web program or client application) authenticate themselves to the server (server application) and that server likewise confirming itself to the client through checking the general public key certificate issued by trusted Certificate Authorities (CA). Since confirmation depends on computerized Certificate, certification authorities, for example, Verisign or Microsoft Declaration Server are a critical part of mutual authentication process. From an abnormal state perspective, the way toward authenticating a...

Methods: a performance difference between Bit-Locker enabled device and Bit-Locker not enabled device with varying of read/write operation is more in non-enabled Bit-Locker device, so we will suggest to encrypt SD card using Existing Method Bit-Locker and also we suggest an Idea that User can Encrypt once in Windows Platform and Decrypt in Other Platform (Ex: Ubuntu) better way of protecting the SD card. Findings: The issues of Bit-Locker device that is we enabled Bit-Locker drive encryption, even the drive is locked but the user can be able to format the entire drive without any interruption.so we have given better solution for these type of problem and also if you lost your portable device without encrypting the unknown user can easily misuse the data present in portable device, so we provided a solution if any unknown user wants to access your data it will ask for password, if unknown user enters 5 times wrong password the portable device will be locked and all the data is format the unknown user cannot perform any read/write operation on portable device. And also if we enabled bitlocker drive encrypted it will have decrypted in windows operating system so we introduced a concept of encrypt once and decrypt in any operating system [EODAOS]. Improvements: The privacy data is more secured compared to Bit-Locker technology, with reset operation if unknown user enters five times wrong password the portable device will be format and lock the portable device with read/write operations. Performance is more improved.

Load balancing is one of the main Challenges in cloud computing which is required to distribute the workload evenly across all the nodes. Load is a measure of the amount of work that a computation system performs which can be classified as CPU load, network load, memory capacity and storage capacity. It helps to achieve a high user satisfaction and resource utilization ratio by ensuring an efficient and fair allocation of every computing resource. Proper load balancing aids in implementing fail-over, enabling scalability, over-provisioning, minimizing resource consumption and avoiding bottlenecks etc. This paper describes a survey on load balancing algorithms in cloud computing environment along with their corresponding advantages, disadvantages and performance metrics are discussed in detail.
