Abstract: Cloud computing has been envisioned as next-generation architecture of IT enterprise. Cloud computing is the internet based model which delivers computing services on demand. Cloud storage moves the users data to large data centers, which are remotely located and on which user does not have any control. Apart having more benefits, this unique feature of the cloud also poses many new security challenges which need to be clearly understood and resolved. The important concerns that need to be addressed in cloud computing is to assure the integrity of data i.e. correctness of his data in the cloud. In this paper we provide a scheme which gives a proof of data integrity in the cloud which the customer can employ to check the correctness of his data in the cloud. This proof can be done by both the cloud and the customer and can be incorporated in the Service level agreement (SLA). Here we are encrypting the hash values and providing the more security. This scheme ensures that the storage at the client side is minimal which will be beneficial for thin clients. Here the computational time is minimized by using integrity and encryption methodology on the data in cloud . It should be noted that this scheme applies only to archive storage data.

Key words : Cloud Computing, Data Integrity, Data Encryption.

Abstract:This Article Presents The Design Of Continuous Video Streaming Compression Of A Networked System For Joint Compression, Error Detection And For Error Correction. Video Compression Applications Are Becoming More Popular Over Wireless Multimedia Sensor Networks. To Save Energy In Bit Transmissions And Receptions Over A Video Sensor Network, The Video File Contents Need To Be Encoded Packet By Packet Before Its Transmission Over Network. The Quality At The Receiver Side Can Be Maximized By Designing The Cross Layer System. The Transmission Rate And Encoding Rate Can Be Controlled By The Cross Layer System. The Fairness Of The Received Video Quality Can Be Developed By The Rate Controller. Instead, An Adaptive Parity Scheme That Drops Samples In Error Is Proposed And Shown To Improve Video Quality. Finally A Low Complexity, Adaptive Video Encoder, Is Proposed That Performs Low Complexity Motion Estimation On Sensors And Implemented To Further Optimize Energy Consumption., Thus Greatly Reducing The Amount Of Data To Be Transmitted And Video File Can Be Decompressed.

Abstract: Unstructured peer-to-peer file sharing networks are very popular in the market. They introduce network traffic. The resultant networks are not perform search efficiently because existing overlay topology formation algorithms are creates unstructured P2P networks without performance guarantees. In this paper, We compares structured and unstructured overlays, Showing through analytical and simulation results how an unstructured solution relying on a scale-free topology is an effective option to deploy for offering services based on equivalent servants. Based on this result, The EQUivalent servAnt locaTOR (EQUATOR) architecture, which overcomes the issues related to the deployment of a scale-free topology for service location in a real network, mainly due to the static nature of the ideal scale-free construction algorithm and the lack of a global knowledge of the participating peers. Simulation results confirmed the effectiveness of EQUATOR, showing how it offers good lookup performance in combination with low message overhead and high resiliency to node churn and failures. Some possible future works are introduced and are related to some complementary issues ranging from the proximity-aware selection of servants to the introduction of proper incentives to encourage nodes to join the EQUATOR overlay and offer their resources.

Abstract: Software testing is an activity that will aim at evaluating an attribute or capability of system and determine that whether it meets required expectations. Test cases can be designed at model level of software development. But to visualize the software model or architecture is difficult due to its large and complex structure. We have presented a novel methodology to extract the sub-model from model diagrams correspond to point of interest to ease the software visualization. The proposed methodology use the concept of model based slicing to slice the sequence diagram to extract the desired chunk.

Abstract: Stealing Identity of the user is a crime in which hackers does the unauthorized activity under the stolen identity by using credentials such as passwords, usernames etc. User verification system provides security layer in addition to username and password by continuously validating the identity of the logged-on user based on their behavioral and physiological characteristics. We introduced a novel method that continuously verifies the user according to characteristics of their interaction with the mouse. The research contribution is in two parts. First, user signature is created according to the user's interaction with mouse while he is doing some predefined activity such as, drawing any alphabet or his signature on canvas application and it gets stored in a database and used for verification purpose. In the second part design hierarchy, to generate a user signature for the current session is discussed. The paper also discusses a decision making system to take decision about to continue the log in or log out from the system based on matching of his current signature and previously created signature. The system developed gives better verification accuracy by reducing the response time of the system.

Title : Human Skin Cancer Recognition and Classification by Unified Skin Texture and Color Features
Country : India
Authors : Dr. Shubhangi D. C., Nagaraj
: 10.9790/0661-1244249      logo

Abstract: In this paper we have proposed a novel method called automatic segmentation of skin lesion in conventional macroscopic images. Many approaches have been proposed to determine the skin cancer. An extensive literature survey is done to study the state-of-art techniques for skin cancer recognition; level set active contours (LSAC), skin lesion segmentation (SLS) and multidirectional gradient vector flow (MGVF) have given considerable results. A technique based on stochastic region merging (SRM) and region adjacency graph (RAG) is adopted in the proposed method. Segmenting the skin lesion from macroscopic images is a very challenging problem due to some factor such as, illumination variation, presence of hair, irregular skin color variation and multiple unhealthy skin regions. To solve all these factors we have introduced a new approach called novel iterative stochastic region merging likelihood for segmenting the skin lesion from macroscopic images based on the discrete wavelet transformation (DWT).

Abstract: An accurate depth location of pelvic land mark could be affected by the acoustic properties of the penetrated tissues and improper depth estimation could lead to a miscalculation of the acetabular cup implant. In the case of obese patient it is very difficult to locate the place of damage. Errors in land mark location leads to the improper treatment by orthopedic surgeons. The aim of this system is to determine pelvic orientation from CT scan images based on patch statistical shape model multilevel measurement utility tools by image calibration system; by applying a hierarchical registration scheme. Here a plastic bones and cadaveric specimen are used. Many approaches have been proposed in the literature to replace the percutanesous digitization, Involvement of the experts in the system to give the solution or conclusion.

Abstract: Denial of Service Attacks basically means denying valid Internet and Network users from using the services of the target network or server. It basically means, launching an attack, which will temporarily make the services, offered by the Network unusable by legitimate users. In others words one can describe a DOS attack, saying that a DOS attack is one in which you clog up so much memory on the target system that it cannot serve legitimate users. Or you send the target system data packets, which cannot be handled by it and thus causes it to either crash, reboot or more commonly deny services to legitimate users. In this paper we focus on the cause and severity caused by some of the major types of DoS/DDos attacks and their countermeasures.

Abstract: Word sense disambiguation (WSD) is an open problem of natural language processing, which governs the process of identifying the appropriate sense of a word in a sentence, when the word has multiple meanings. Many approaches have been proposed to solve the problem, of which supervised learning approaches are the most successful. However supervised machine learning are limited by the difficulties in defining sense tags, acquiring labeled data for training and cannot utilize raw un-annotated data. Semi-supervised learning has recently become active research area because it require small amount of labeled training data and sometimes able to improve performance using unlabeled data. In this paper, we discuss the methods of semi-supervised learning and their performance.

Keywords: -word sense disambiguation, supervised learning, semi-supervised learning.

Abstract: Cloud computing provides users to remotely store their data and high quality of cloud applications by reducing risk of local hardware and software management. To protect data from outsourced leakages, we propose a flexible distributed storage integrity auditing mechanism (FDSIAM), these mechanism utilizes the homomorphic tokens (MAC address and secret key), blocking and unblocking factors and distributed erasure-coded data. Suppose user is out of station we can generate alert information to mobile devices, if any attacker attacks the data immediate message has been given to particular user through mobiles. The auditing results not only ensure storage correctness, but simultaneously identifies misbehaving server. Our proposed design provides very lightweight communication and computation cost for users to audit the data. Cloud data are dynamic in nature, our design supports secure and efficient dynamic operations on outsourced leakages, including block insertion, modification, append and delete operations. Our experimental results are highly efficient and secure against malicious data modification attack, server colluding attacks and byzantine failures.

Abstract: In this paper we have taken one of the most amazing network concepts which makes network simpler. By considering the aspect of both side as of good and its related issues like most important and unavoidable is i.e. "Security". Hence, enhancing the security in wireless networks has become of vital importance. In this perspective of concept, we mainly study two security aspects of wireless networks. One is service confidentiality and access control that is to ensure only legitimate users can access service data according to their privileges and in other perspective is of service attack. Wireless broadcast is a convenient and effective approach for disseminating data to a number of users. User training in computer and network security is crucial to the survival of modern networks, yet the methods employed to train users often seem ineffective. The secrecy issues in the context of mandatory and discretionary access control in a multilevel networked environment. Hence of, we stressed on two aspects key management scheme is proposed to address secrecy and efficiency in broadcast services, where keys are used for service confidentiality and access control.

Abstract: Mobile Ad-Hoc Networks (MANETS) are dynamic in nature. Because of its dynamic nature of its network infrastructure, MANETS are highly vulnerable to attacks. Among these attacks routing attack has considerable attention, since it could cause most destructive damage to MANET. In existing system, binary isolation and DRC techniques are used to isolate the malicious nodes. However, binary isolation leads to unexpected network portioning and DRC is associative and non-weighted. In this paper we proposed adaptive risk-aware response mechanism with an extended trusted center, where a risk-aware approach which is based on an extended Dempster-Shafer mathematical theory of evidence introducing a notion of importance factors. Adaptive decision making technique has been used to prevent routing attacks. We also analyses and evaluate routing cost with respect to different technique.

Title : To Improve the Recognition Rate with High Security with Ear/Iris Biometric Recognition Technique with feature Extraction & Matching
Country : India
Authors : Paridhi Agarwal , Dr. Naveen Hemrajani

Abstract: Ears are the new biometric with major advantage in that they appear to maintain their structure with increasing age. Contending that the ear is mainly a planar shape 2D images are used, which are consistent with deployment in surveillance and other planar- image scenarios. In this paper, a new model-based approach to ear biometrics is proposed. The model parts are derived by a stochastic clustering method on a set of scale invariant features on a training set. The model description is extended by proposing a new wavelet-based analysis with a specific aim of capturing information in the ear's outer structures. The performance is evaluated on test sets selected from the XM2VTS database. By results, both in modeling and recognition, the new model-based approach does indeed appear to be a promising new approach to ear biometrics. The recognition performance has improved notably by the incorporation of the new wavelet-based analysis. A model-based approach has an advantage in handling noise and occlusion. A wavelet can offer performance advantages when handling occluded data by localization. A robust matching technique is also added to restrict the influence of corrupted wavelet projections. Furthermore, the automatic enrolment is tolerant of occlusion in ear samples. The hybrid method obtains promising results recognizing occluded ears. The results have confirmed the validity of this approach both in modeling and recognition. The new hybrid method does indeed appear to be a promising new approach to ear biometrics, by guiding a model-based analysis via anatomical knowledge.

Title : "The Driving Analysis System through Wireless Network"

Abstract: This paper studies the process of obtaining a driving license in INDIA. On the average, individuals pay about twice the official amount to obtain a license and very few take the legally required driving test, resulting in many unqualified yet licensed drivers. The magnitude of distortions in the allocation of licenses increases with citizens' willingness to pay for licenses. These results support the view that corruption does not merely reflect transfers from citizens to bureaucrats but that it distorts allocation. The paper also shows that partial anti-corruption measures have only a limited impact because players in this system adapt to the new environment. Specifically, a ban on agents at one regional transport office is associated with a high percentage of unqualified drivers overcoming the residency requirement and obtaining licenses at other RTOs. Our project avoids paper cost, identifies correct driver who is eligible for driving, If our product made mandatory to all vehicles Traffic management becomes easier, E-tolling: Eliminates the delay on roads by collecting tolls electronically, Applying for driving license becomes much more convenient, Bring consistency in test drive process, Reduce man power. As our survey, around 1500 RTO centers are there in India. Actual cost for applying driving license is Rs250, most of people go through mediator to get their DL and pay about RS1000 to mediator. Daily 30000 people register for DL in India add total amount paid to mediator is RS 30L per day and It turns into Rs100Crores per year. According to times of India 1300 people are dying due to accidents per day in India, most of them(10%) are got their DL from mediator who are unfit for driving.

Abstract:While routing Wireless Sensor nodes in the Multi-hop network ,nodes may undergo some attacks such as sink hole attack, worm hole attack, Sybil attack etc., by the attackers through identity deception. So, to secure WSN's against attackers or hackers misdirecting the nodes in the network while routing, in our base paper we have designed and implemented TARF, a robust trust aware routing framework concept for dynamic for WSN's. TARF provides trustworthy and energy-efficient route and also it provides security against all these attacks which are mentioned above. In our work, we are using modern technology like ECC i.e., Elliptic Curve Cryptography for encoding and decoding purpose. To know the performance of this TARF routing, in our paper we are comparing TARF Routing with Existing Routing and generating routing tables. To find the secure network discovery we are generating Combinatorial Key for Pre Key-Distribution in TARF Network. In the handheld devices like mobile we are trying to find the attacker information.
