Title : Twin Key Implementation in Aes
Country : India

Abstract: In February 2001, NIST announced that a draft of the Federal Information Processing Standard (FIPS) was available for public review and comment. Finally, AES was published as FIPS 197 in the Federal Register in December 2001. Rijndael's has been standard by the NIST as the Advanced Encryption Standard (AES). This makes the AES essential and necessary for protection of data. We propose to reconfigure the structure of the advanced encryption standard (AES), especially in constant rotation and replaced it with variable rotation using a single key (Twins Key) that can be used for both ciphering and inverse ciphering. We demonstrate that changes can develop twin ciphers which are similar to the original one. The use of single key in AES helps to solve complexity faced during ciphering and deciphering, but it still maintains the same degree of Confusion and Diffusion. Confusion and diffusion make the use of key thus more very complex and very difficult to discover it. The use of a single key also makes this process more time efficient and variable rotation can protect data from continuous tries to attack encryption algorithm.

Keywords: AES, Twin key, Encryption, Decryption.

Abstract: The objective was to examine the frameworks needed to foster innovations and to mobilize innovation towards co - creating computers in the context of developing countries' challenge of unreliable energy supply, in order to enhance performance of information and communication technology (ICT) as teaching aids for educational attainment. The basic underlying assumption is that computers are the simplest interactive instructional devices and that energy is a fundamental requirement for its functionality. A sample survey was conducted to ascertain the existing energy and ICT situation and needs amongst students. 213 questionnaires were administered to students of the University of Ibadan, and the Polytechnic, Ibadan in Oyo state of Nigeria. Investigation on technologies that can make the computer more relevant to users and adaptable to the environment revealed 51.4% suggesting longer battery life, 21.8% - double battery pack, 8.5% - both longer battery life and double battery pack and 7% - a reduction in the energy consumption of component parts of the computer. Apparently, there is a need to maximize the full potentials of the computer to enhance educational development and to expose students across the globe to equal platforms and opportunities for learning.

Title : Privacy and Security in Data Storage Using Two Layer Encryption and MAC Verification
Country : India

: 10.9790/0661-16581723     logo

Abstract: For the privacy and security of data stored in data storage a new Two Layer Encryption (TLE) approach is developed. This technique performs an encryption at two layers based on some ACP(Access Control Policies)on the data owner as well as on the datastorage.The data owner and the data storage utilizes a key management scheme with the help of a key generating algorithmABGKM (Attribute Based Group Key Management)whereby the actual keys do not need to be distributed by the users. The single layer encryption approach using keyword search has some drawbacks such as the privacy of the identity attributes of the users is not taken into account so that the data storage can learn some information about the users and the organization. The random keyword search request also cause loss of information and degrade the privacy of encrypted data. This thesis of two layer encryption allows more secure and private way to handle data updates, user dynamics and policy changes. If there is a change in user dynamics or policy the outer layer of encryption needs to be updated. Since the outer layer encryption is done at the data storage, no transmission of data required between the data owner and data storage. The user who satisfies the access control policies should be able to decrypt the keys twice in order to access the data makes the system more secure and private. Hence my propped thesis has a newly added advantage of two layer encryption using Attribute Based Group Key management (ABGKM) provides a strong secure layer for data storage in servers.

Title : Text Clustering in Distributed Networks with Enhanced File Security
Country : India
Authors : Teena Susan Chandy
: 10.9790/0661-16582430     logo

Abstract: Text Clustering technique is widely used in both centralized and distributed environments for information retrieval. Centralized approaches are used in traditional text clustering algorithms. In such approaches, clustering is performed on a dedicated node and also they are not suitable for deployment in large distributed networks. This centralized approach require high processing time and retrieving time during searching due to scalability of users. To overcome this, the Probabilistic text clustering for peer to peer(PCP2P) algorithm was introduced. It provides improved scalability by using a probabilistic approach for assigning documents to clusters. Only most relevant clusters are considered for comparison with each document. PCP2P alone does not provide any security for the system. It only ensures efficient information retrieval of text data by assigning document to most relevant cluster. This project is implemented within a medical research environment. Here, the system is implemented using this PCP2P algorithm and an enhanced version of a security related technique called LZW. Enhanced LZW technique can ensure secure transmission within the system. This technique includes hiding information directly in compression codes. Lempel -Ziv-Welch (LZW) coding is a well known lossless compression algorithm is simple and does not require prior analysis of the source or send extra information to the decoder. This introduces a new input table which contains 255 contents. This method, reversibly embeds data in LZW compression codes by modifying the value of the compression codes. The value of the LZW code either remains unchanged or is changed to the original value of the LZW code plus the LZW dictionary size according to the data to be embedded.

Abstract: Flash memory storage such as SSDs (Solid State disks) have been gaining popularity due to its low energy consumption and durability in embedded systems and laptops. With the fast technical improvement, Solid State Disks (SSDs) are becoming an important part of the computer storage hierarchy to significantly improve performance and energy efficiency. However, due to its relatively high price and low capacity, a major system research issue to address is on how to make SSDs play their most effective roles as a high-performance storage system in cost- and performance-effective ways. In this paper, we describe a NAS prototype that eliminates most software overheads and makes Solid State Disks a high-performance storage system in cost- and performance-effective ways. NAS integrates a network adapter into SSDs, so the SSDs remove the random access time, Reduce administrative overhead while delivering scalable, reliable data storage. NAS can also give support block based I/O rather than traditional NAS system which supports only file I/O protocol such as NFS and CIFS. Our scale-out NAS solutions can boost capacity and performance while enabling flexible provisioning, no disruptive operations, easy scalability, and virtualization. As the storage and processing requirements of the file server continued to increase data security and integrity became difficult to manage in conventional NAS, this NAS can ensure the data integrity and sanctity as well.

Title : Optimized Hypergraph Based Social Image Search Using Visual-Textual Joint Relevance Learning
Country : India
Authors : Arya S
: 10.9790/0661-16584049     logo

Abstract: Recent years have witnessed a great success of social media websites. Tag-based image search is an important approach to access the image content of interest on these websites. However, the existing ranking methods for tag-based image search frequently return results that are irrelevant or lacking in diversity. Most of the existing methods estimate the relevance of images by using tags and visual characteristics either separately or sequentially. The proposed system uses an approach that utilize simultaneously both visual information and textual information in real time to estimate the relevance of user tagged image. The method used to determine the relevance estimation is the hypergraph learning approach.

Abstract: Text based password is most commonly used user authentication .To log on to websites, users must memorize the selected password. Password based authentication can resist brute force and dictionary attacks, if they select a stronger password but users often select weak password for their convenience and remembrance. They reuse password in different sites for simplicity, it would make the attacker to find their passwords in different sites. These are caused by the negative impact of human behavior. Typing password on untrusted computers suffers from stealing of password i.e. shoulder surfing. Then researchers have designed graphical password which made attackers to find out the commonly selective areas (Hotspots). Some researchers have focused on three-factor authentication for reliability and depends on password, token, biometric. For this authentication, the user must input a password and provide a pass code generated by the token, and scan her biometric features (e.g., fingerprint). This is a comprehensive defense mechanism against password stealing attacks, but it requires high cost. Another user authentication is Opass,

Abstract:Construction of a decision tree is a well researched problem in data mining. Mining of streaming data is a very useful and necessary application. Algorithms such as VFDT and CVFDT are used for decision tree construction, but as a lot of new examples are added, a new optimal model needs to be constructed. Here in this paper, we have provided an algorithm for decision tree construction which uses discriminant analysis, to select the cut point used for splitting tests, thus optimizing time complexity from O(nlogn) to O(n). We have also analyzed several learning strategies such as dynamic ensemble, contextual, forgetting and detection approaches. We have also discussed handling of concept drift which occurs due to gradual change in the data set using the naive Bayes classifer at each of the inner node.

Abstract: Over the previous couple of years, organizations across public and personal sectors have created a strategic call to show massive information into competitive advantage. The challenge of extracting price from huge information is comparable in many ways to the antique drawback of distilling business intelligence from transactional knowledge. At the center of this challenge is that the method costumed extract information from multiple sources, remodel it to suit your analytical wants, and load it into an information warehouse for consequent analysis, a process called "Extract, Rework , Batch" (ERB). The character of huge knowledge needs that the infrastructure for this method can scale cost-effectively.

Abstract: Healthcare is the diagnosis, treatment, and prevention of disease, illness, injury, and other physical and mental impairments in human beings. Healthcare is delivered by practitioners in allied health, dentistry, midwifery-obstetrics, medicine, nursing, optometry, pharmacy, psychology and other care providers. In healthcare service to provide better performance to identify some diseases like blood pressure, skin cancer, diabetes etc. with the sensor devices those are connected with home server by using wireless sensor or wired network policies. The size of data sets being collected and analyzed in the industry for healthcare business intelligence is growing rapidly. In healthcare service case we have to concern about massive data services. To store and process huge amount of unstructured data by using traditional database system is so difficult. To alleviate this drawback we can use Hadoop architecture that has functionality to store and process huge amount of unstructured data.

: 10.9790/0661-1658106111     logo

Abstract: MRI head scan images contains some non-brain tissues and it is necessary to remove these non-brain tissues for further processing. The Brain Extraction Tool (BET) is one of the most popular brain segmentation technique which removes the non-brain tissues in MRI head scan volumes. It is a simple and robust brain extraction method. It is a boundary based method and uses deformable surface to detect brain boundaries. Due to its over smoothing capabilities it always under-segment the brain images by including more non-brain tissues in its final segmentation. The aim of this proposed method is to overcome the problems encountered with the existing BET method by using the marker-controlled watershed segmentation.
