Abstract

Security is the main concern in today’s world and securing data from unauthorized access is very important. Different techniques should be used to protect confidential image data from unauthorized access as each type of data has its own features. Encryption is used to prevent data from unauthorized access and with the appalling headway in network technology seen in the past decade; it has become the need of time to encrypt the images before sending over open network. Cryptography is a very effective way to protect transmitted information. Though researchers have proposed contrastive methods to encrypt images, only few methods provide security and confidentiality. So, here we introduce a new image encryption method which encrypts the image using a key involving Armstrong numbers and Prime numbers. The basic idea is to perform double encryption of images, which involves encryption first by Armstrong number followed by Prime number. Algorithms are proposed for efficient implementation of Double Encryption. Moreover, an image-based data requires more effort during encryption and decryption. Nowadays, images are vastly used in today's world to represent information in various domains varying from corporate world, health care, document organization, military operations etc.

Abstract

Voters often find the postal ballots very inconvenient and time consuming as a result the voting response rates is often lower. Online voting system is considered to facilitate the central government’s new policy of giving voting rights to the Indians living abroad so that they can cast their vote using internet and to also increase voter responses. It could reduce the expenditure involved in setting up and staffing poll sites. The method for data hiding is based on the novel approach of using Steganography and cryptography together using images as cover objects for steganography and as keys for cryptography. Most of the traditional systems have adopted a secret key to authenticate the user information. The use of secret key may direct to undesirable circumstances when the secret key is lost, or forgotten. Biometric authentication systems are considered to be more useful since it involves no secret key that might be feared to be forgotten by the user or key to be lost and not just that a single biometric trait can be used to access several accounts without the need of remembering passwords for all those accounts. In this paper Eyebrow is used as a biometric measure to enhance the security aspect of the System. Here Active contour algorithm is used to get accurate Eyebrow contour, which makes this application a highly secured biometric cipher application.

Abstract

The present study was designed to investigate the antidepressant effects of Albizzia lebbeck leaves in various animal depression models. The alcoholic extract (70% v/v ethanol) of Albizzia lebbeck leaves (200 and 400 mg/kg. p.o) was administered once daily for seven successive days to separate groups of young male swiss albino mice. The immobility periods of control and treated mice were recorded in two behavioral despair models forced swim test (FST), tail suspension test (TST) and the effect of extract on locomotor function of mice was studied using actophotometer. The antidepressant-like effect of tested drug was compared to that of imipramine (15 mg/kg. p.o) and fluoxetine (20mg/kg.p.o). The leaf extract at doses of 200 and 400 mg/kg significantly decreased the duration of immobility time in a dose dependent manner in both FST and TST.

The extract did not show significant effect on locomotor activity of mice. The efficacy of tested extract was found to be comparable to that of imipramine and fluoxetine. Our results suggested that the ethanolic extract of Albizzia lebbeck leaves exerts antidepressant-like effect.

Abstract

Objectives: To obtain a classical tracking device for helping common people with the aim of providing security and precaution. Methods: Multipurpose tracking system allows to track different types of people namely children, women and elderly people by insisting three buttons one for children, other for women and another for elderly people. These system alerts the receiver end people by using signals of GPS and sending message and calls through GSM and GPRS. In this work, voice recorder and a camera is initiated to know the actual situation in the front end as an image through email and voice through speaker. Findings: To tackle the above problem and safeguard them, we have found a small device in a locket model with advanced technologies like GPS (Global Positioning System), GSM (Global System for Mobile Communication), GPRS (General Package for Radio Service) which helps to track them latitudinal and longitudinal directions through satellite where the alert message and calls through voice playback are send to the receiver end like parents, police control room and attender and a camera which helps in taking visual images and send to the receiver end through email at the time of risk.

Abstract

So far in cloud computing environment, all the resources and services are used as an on-demand request basis from the client end. All typical service issues have been solved with the optimal cloud resource customization policies. The role of edge computing is enabling the data processing operations at the edge network which will operate in the cloud computing platforms. Due to increased amount of usage in the client location the proper devices need to be well connected with an internet. Edge mechanism is implemented in the real-time service based operation which will examine the upstream and downstream functional units will apply the real-time local data analysis in the data centre locations. The hybrid clouds will execute the service request form both the private cloud and public cloud users. These services and request based resources can be literally focused by the cloud service provider (CSP) and managed service provider (MSP) who will provide the cloud services uninterruptedly to the requested users. When the multiple services are executes in the edge network then the cloud vendor does not properly handle the services through the secured environment. Such kind of problem will lead the user to loss their control activities on the hybrid cloud solutions location. The proposed approaches of edge computing in hybrid cloud solutions are improving the service by applying the fuzzy logic control implementation factors. The cloud sim can be used as a simulator in the proposed model.
