Investigation and Analysis of Location based Authentication and Security Services of Wireless LAN’s and Mobile Devices

Abstract

In the last two decades lot of research and development occurs on Location-Based Authentication and Security Services (LBASSs) which allow users to see where their friends are, to search location-tagged content within their local area networks, and to meet others nearby. Previously the data can be accessed from anywhere and any time. Hence lot of unexpected misjudgment were happened due to location independent authentication protocols. The recent availability of open mobile platforms, such as Apple iPhones and any Android phones, makes LBASSs much more accessible to mobile users. After rigorous research funding into this area leads to regulate the access that resources preserved in particular locations. Therefore we improve the development of security from location. We have been study how users share their location in real world, we collected traces from a commercial LBS services operated by a startup company. In this paper, surveyed all algorithm schemes since two decades and bring out detailed analysis over geo encryption, location authentication, location privacy, enhanced location security, User authentication mobility parameters, tolerant distances under smart living applications. To the best of our knowledge, this study fills the gap between old technologies and new technologies and presents fine tuning quantitative analysis of a real-world LBS services. In this paper authors investigate the various key issues and their methodologies for location authentication in WLAN and mobile devices. This paper leaves several ideas for researchers to mitigate issues in location privacy and authentication areas for better future.

A Secure Framework for Communicating Multimedia Data in Cover Images using Hybrid Steganography Algorithms in Wireless Local Area Network

“…There are various information hiding approaches have been added to get security while using cryptography. 4. Least significant method [1] shows outstanding methodology upto 1990 year, after there are many researches survey discovered and survey a lot.…”

“…This paper investigates the various ideas [2][3][4][5][6][7][8] of hiding techniques and then analyses the most common forms multimedia content as a secret information kept in cover image, such as watermark, fingerprint. To assess the robustness of cover image even after hiding multimedia data as secret data using metrics of image quality concept [12].…”

“…The main goal of this paper is that it should hide all multimedia data using hybrid steganography working in wireless environment like 802.11 standard, all they exist in the any system in the network(WLAN) and immediately stop them from spreading all through the network. In this paper, we suggested that the required inputs are existence of image manipulation tools and the desired outputs are avoid the difference between stego image [3] [4] and cover image. If big enough secret multimedia data is able to hide and to be transferring over the wireless network, it will be create tamper proof image transfer even hiding any multimedia.The majority of data hiding techniques for the concealing of secret multimedia information would communicate to authors suffer from not upholding secret data to carry across WLAN.…”
