A Survey on Different Approaches of Attribute based

Encryption For Cloud File System

Swati Sengar*, Satyendra Singh Rawat Department of Computer Science, SRCEM, Gwalior, MP, India

Abstract Cloud computing has emerged as a solution for organizations that desire services on lease. It enables convenient and on-demand network access to a centralized pool of

configurable computing resources. Among many of its applications, File distributing and

sharing is one of the most commonly used services in cloud computing. The requirement of data security grows with the faster growing cloud computing. One feasible solution is

Attribute based encryption (ABE). In this paper a hybrid approach that blends ABE and Shifted Huffman Encoding (SFT) for encryption is proposed. The solution focus on data

security achieved by Attribute based encryption and data compression through Shifted

Huffman Encoding. This paper is a comparative study of different ABE based techniques for Cloud Environment.

Keywords: Cloud computing, hierarchical attribute-based encryption, fine-grained

access control, scalability

Performance Analysis of Fusion Classifier of Face

Recognition System based on ANN and GA

Rizoan Toufiq, Md. Rabiul Islam*

Department of Computer Science & Engineering, Rajshahi University of Engineering

& Technology, Rajshahi, Bangladesh

Abstract Though a lot of significant work has been done for recognizing and improving the performance in facial pattern, most techniques have been developed based on a

single classifier. But most often, the performance of the classifier is not satisfactory in

some case. It has been proposed that the performance of face recognition will be improved by fusing two or more classifiers. We can combine the information/data in

different level i.e., feature levels, data levels or classifier levels. We developed two

classifier named back-propagation neural network and genetic algorithm. Then we combined their output based on newly developed fusion algorithm. The performance of

the proposed fusion classifier can give better recognition rate compared with the performances of individual classifier. Here the fusion has been occurred in two stages.

First we have selected the close classified facial pattern for testing pattern by using back-

propagation classifier and genetic algorithm classifiers. Then final facial image has been selected among the previously selected facial image by calculation some feature and

distance from the test facial pattern.

Keywords: fusion classifier; back-propagation algorithm; genetic algorithm;

principal component analysis

Time Base Modulation Approach to Audio Watermarking

Chandrashekhar S. Shinde* Computer Science & Engineering Department, Dr. J. J. Magdum College of Engineering,

Jaysingpur (MS) India

Abstract A new method is presented for inaudibly hiding information in an audio signal by subtly

applying time-scale modification to segments of the signal. The sequence, duration, and degree of the time-scale modifications are the parameters which encode information in

the altered signal. By comparing the altered signal with a reference copy, compressed

and expanded regions can be identified and the hidden data recovered. This approach is novel and has several advantages over other methods: it is theoretically noiseless, it

introduces no spectral distortion, and it is robust to all known methods of reproduction, compression, and transmission.

Keywords: Audio watermarking, time base modulation, tempo map

Twitter based TV Rating Analysis with TV-viewing

and Sentiment Analysis

Amrapali Mhaisgawali*, Dr. Nupur Giri

Department of Information Technology , Vivekanand Institute of Technology, Chembur, Mumbai, India

Abstract Social Media is now used as a back channel to TV programs by viewers who would like

to express their opinion about watching programs or just simply put on records of TV

viewing. TV viewing rate is a critical indicator regarding the popularity of programs.

Now a day’s social media is generally used to gather crowd sentiments to gather this

information. Current methodologies based on Neilsen TV ratings adopt small sample group for the same. This approach saves cost, time as well as gives preliminary

information. But it fails to bring out the actual sentiments on the real time samples. Our

work proposes to use social media typically twitter to gather real time crowd sentiments regarding different TV shows and compute TRP based on type number etc. giving

descriptive analysis.

Keywords: Television rating point, micro-blogging, sentiment analysis
