Abstract:Enterprises protect their internal storage and retrieval process using firewalls and also protect it from insider attacks by formulating secure data access procedures. If the enterprises are willing to store data in cloud, cloud computing service providers have to take care of data privacy and security. A common way to achieve security is encryption/decryption mechanism employed by cloud service providers. However, performing both tasks such as storage and encryption/decryption mechanism by cloud server causes security problems as the administrators know the sensitive information and may involve in illegal practices. To overcome this problem, this paper presents a mechanism where the storage is done by one provider while encryption/decryption mechanisms are provided by another service provider. In the proposed system the party that uses cloud storage services must encrypt data before sending it to cloud while the service provider who is responsible for encryption/decryption must delete data once encryption/decryption process is completed. To illustrate the proposed mechanism, this paper uses a CRM service example that demonstrates how the parties involved in secure storage and retrieval when data is saved to cloud. It also provides insights into multi-party SLAs for the proposed system.

Abstract:IT has moved into next generation with cloud computing being realized. The way application software and databases are stored has been changed. Now they are stored in cloud data centers in which security is a concern from client point of view. The new phenomenon which is used to store and manage data without capital investment has brought many security challenges which are not thoroughly understood. This paper focuses on the security and integrity of data stored in cloud data servers. The data integrity verification is done by using a third party auditor who is authorized to check integrity of data periodically on behalf of client. The client of the data gets notifications from third party auditor when data integrity is lost. Not only verification of data integrity, the proposed system also supports data dynamics. The work that has been done in this line lacks data dynamics and true public auditability. The auditing task monitors data modifications, insertions and deletions. The proposed system is capable of supporting both public auditability and data dynamics. The review of literature has revealed the problems with existing systems and that is the motivation behind taking up this work. Merkle Hash Tree is used to improve block level authentication. In order to handle auditing tasks simultaneously, bilinear aggregate signature is used. This enables TPA to perform auditing concurrently for multiple clients. The experiments reveal that the proposed system is very efficient and also secure.

Abstract:The World Wide Web is a popular and interactive medium to distribute information in this scenario. The web is huge, diverse, ever changing, widely disseminated global information service center. We are familiar with terms like e-commerce, e-governance, e-market, e-finance, e-learning, e-banking etc. for an organization it is new challenge to maintain direct contact with customers because of the rapid growth in e-commerce, epublishing and electronic service delivery. To deal with this there is need of intelligent marketing strategies and CRM (customer relationship management) i.e. the effective way of integrating enterprise applications in real time. Web mining is the vast field that helps to understand various concepts of different fields. Web usage mining techniques are attempted to reason about different materialized issues of Business Intelligence which include marketing expertise as domain knowledge and are specifically designed for electronic commerce purposes. To this end, the chapter provides an introduction to the field of Web mining and examines existing as well as potential Web mining applications applicable for different business function, like marketing, human resources, and fiscal administration. Suggestions for improving information technology infrastructure are made, which can help businesses interested in Web mining hit the ground running.

Abstract:A large amount of storage and bandwidth is needed when data transmission is done using uncompressed digital video. This results in a large amount of data that demands the need of video compression. Many of the existing video compression standards share common or similar coding tools, and there is currently no explicit way to exploit such commonalities at the level of implementations. Moreover, the possibility of taking advantage of the continuous improvements in coding is only possible by replacing the existing approach with a new one. This paper proposes an efficient video content representation by exploiting the temporal redundancies using optimal extraction of repeated frames and scenes. A new standard for video coding called Optimal Repeated Frame Compensation (ORFC) is used, in which the repeated frames are combined together to form a single frame in order to reduce the total number of frames..

Abstract:In recent years, internet revolution resulted in an explosive growth in multimedia applications. The rapid advancement of internet has made it easier to send the data/image accurate and faster to the destination. Besides this, it is easier to modify and misuse the valuable information through hacking at the same time. Digital watermarking is one of the proposed solutions for copyright protection of multimedia data. A watermark is a form, image or text that is impressed onto paper, which provides evidence of its authenticity. In this paper an invisible watermarking technique (least significant bit) and a visible watermarking technique is implemented.
Key words:Watermarking, Least Significant Bit (LSB), JPEG (Joint Photographic Experts Group), Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR).

Abstract:Data compression plays an important role to deal with high volumes of DNA sequences in the field of Bioinformatics. Again data compression techniques directly affect the alignment of DNA sequences. So the time needed to decompress a compressed sequence has to be given equal priorities as with compression ratio. This article contains first introduction then a brief review of different biological sequence compression after that my proposed work then our two improved Biological sequence compression algorithms after that result followed by conclusion and discussion, future scope and finally references. These algorithms gain a very good compression factor with higher saving percentage and less time for compression and decompression than the previous Biological Sequence compression algorithms.
Key words:Hash map table, Tandem repeats, compression factor, compression time, saving percentage, compression, decompression process.
