 Abstract

secure data storage and retrieval is the best research directions in cloud. Though lots of searchable encryption scheme have been proposed some of them support efficient retrieval over the documents. Which are encrypted based on their attributes. In this paper a hierarchical attribute based encryption scheme is designed for a data collection. A set of documents is encrypted together if they share an integrated access structure. Compared with the CP policy attribute based encryption schemes, both the cipher text storage space and time costs of encryption and decryption are saved. Then, an index structure named attribute based retrieval features tree is constructed for the document collection based on the TF-IDF model and the documents attributes. A depth first search algorithm for the attribute based retrieval features tree is designed to better the search efficiency which can be further improved by parallel computing. Except for the documents collections in our scheme can be applied to other data sets by modifying the attribute based retrieval features tree slightly. A thorough analysis and series of experiments performed to illustrate the security and efficiency of the proposed scheme.

Boundary detection of brain tumor from the MRI is a time consuming task. This is due to the diversity in shape, size and appearance of the tumors. Boundary detection in MR image with brain tumor is an important image processing technique applied in Radiology for 3D reconstruction. To segment the boundary of the brain tumor region, many segmentation techniques have been emerged in image processing like the region based segmentation, the boundary based segmentation. Moreover, even in some of the normal tissue region, edge created by this method has also been encompassed. In this paper, Kapur Entropy measure method is used for boundary detection of brain tumor segmentation and its earlier detection. In the proposed approach threshold selection is done on the basis of different Kapur entropy measure. Simulation results for different MRI Images are also presented and it is observed that in 3D MRI Images, Kapur entropy is able to detect the brain tumor at its earlier stage.

 Abstract

Sports is considered as a psycho-social activity. Along with physical, physiological and technical aspects sports has a psychological and social dimension. The most of the people share a common interest in sports competitions. But, the quality of sports participation of the athletes and sportsmen is determined by their psychological factors. In the field of exercise and science the role of sports psychology has been considered. Sports psychology as a branch of sports and exercise science focuses on the psychological aspects. Thus sports psychology incorporates the theoretical models and approaches of psychology.

 Abstract

The growing number of mobile and IoT devices has nourished many intelligent applications. In order to produce high-quality machine learning models, they constantly access and collect rich personal data such as photos, browsing history and text messages. However, direct access to personal data has raised increasing public concerns about privacy risks and security breaches. To address these concerns, there are two emerging solutions to privacy-preserving machine learning, namely local differential privacy and federated machine learning. The former is a distributed data collection strategy where each client perturbs data locally before submitting to the server, whereas the latter is a distributed machine learning strategy to train models on mobile devices locally and merge their output (e.g., parameter updates of a model) through a control protocol. In this paper, we conduct a comparative study on the efficiency and privacy of both solutions.

ABSTRACT The illiterate person is not seen with good attitude in the present society. Therefore every parent tries their best to educate their child. It is only through education that the attitudes and refinement of children's tendencies are made, so that their behavior is balanced and controlled. Education plays an important role in the formation of a person's habits. That is, habits are formed according to the kind of education a student gets. But in our country, the mainstay of education, the condition of primary education is very pathetic, such as - after admission in school, the child leaves school in the middle. Somewhere the school is away from home, somewhere the distribution of primary schools is not found properly, and somewhere there is a shortage of qualified teachers in the schools. Due to this, many children are deprived of education and the efforts for universalisation of primary education are pushed. Various schemes are being run by the government and a lot of budget is also being spent, but the result is not relatively satisfactory. Defective government policies, teaching system, teachers' perceptions of teaching work and various regional and social problems are responsible for this. In this paper, deep thinking has been contemplated related to this problem and possible solutions to the problem have been presented.

 Abstract

Image block matching is the main step of duplicated region detection for exploring copy-paste image forgery. Several manipulations have been made in images due to high powerful tool evolvement. A copy and move forgery may occur in images where they cannot be easily. The image are get analyzed particularly for the region where the image get forged. The region of the image get copy and paste will be known with the proposed Gaussian RBF kernel PCA. High computational time in this step is one of the most important problems to find similar regions. This paper presents a block based digital image watermarking scheme that is dependent on the mathematical technique of singular value decomposition (SVD). Traditional SVD watermarking already exists for watermark embedding on the image as a whole. In the proposed approach, the original image is divided into blocks, and then the watermark is embedded in the singular values (SVs) of each block separately. Furthermore, we determine performance of proposed algorithm based on time complexity function.

 Abstract

Virtualization is a prime factor in Cloud Computing; there are various virtualization technologies existing in the industry, nowadays virtualization is implemented with good performance benefits. It has achieved, very good overall performance, but it shows deflection in the system and IO performance concerning the workload running on virtual machines. If the VM has CPU intensive Workload then it produces considerable overheads in system performance if VM has a mix (CPU and IO intensive) type of workload, it produces a bit more overhead. However, IO intensive workloads like databases still suffer from performance degradation in virtualization. In this paper, we have analyzed disk IO handling mechanism in para-virtualization technology Xen. We have conducted experiments with database workload measured performance with different IO scheduling strategies and proposed a framework for improving disk I/O performance for database workload in a virtualized environment, which consists of a possible configuration of Linux IO scheduling strategies according to its features. The key idea is to make disk I/O requests handled by the correct scheduler instead of default scheduler shows better performance in IO Wait and read and write operations.
