A Comparative Analysis of Mobile Operating Systems Rina
International Journal of Computer Sciences and Engineering Open Access Research Paper Vol.-6, Issue-12, Dec 2018 E-ISSN: 2347-2693 A Comparative Analysis of mobile Operating Systems Rina Dept of IT, GGDSD College, Chandigarh ,India *Corresponding Author: [email protected] Available online at: www.ijcseonline.org Accepted: 09/Dec/2018, Published: 31/Dec/2018 Abstract: The paper is based on the review of several research studies carried out on different mobile operating systems. A mobile operating system (or mobile OS) is an operating system for phones, tablets, smart watches, or other mobile devices which acts as an interface between users and mobiles. The use of mobile devices in our life is ever increasing. Nowadays everyone is using mobile phones from a lay man to businessmen to fulfill their basic requirements of life. We cannot even imagine our life without mobile phones. Therefore, it becomes very difficult for the mobile industries to provide best features and easy to use interface to its customer. Due to rapid advancement of the technology, the mobile industry is also continuously growing. The paper attempts to give a comparative study of operating systems used in mobile phones on the basis of their features, user interface and many more factors. Keywords: Mobile Operating system, iOS, Android, Smartphone, Windows. I. INTRUDUCTION concludes research work with future use of mobile technology. Mobile operating system is the interface between user and mobile phones to communicate and it provides many more II. HISTORY features which is essential to run mobile devices.

We Hack Wii / USB Loader
Don't upgrade to Wii Firmware 4.2! Instead of updating your Wii firmware, you can just use DOP-Mii to update specific channels such as the Nintendo Channel or Wii Shop Channel without updating the Wii System Menu. This will allow you to shop with the latest Wii Shop Channel without updating the Wii System Menu. However, the guide below DOES work if you are on 4.2 and want to hack your Wii. Don't use IOS60-Patcher for launching games from SD! Instead use DOP-Mii to re-install IOS60 (if you are on Wii Firmware 4.0 or 4.1) or IOS70 (if you are on Wii Firmware 4.2) with the signature hash check (trucha bug). Also, if you are using Preloader and you "dop" IOS60 or IOS70, remember to reinstall Preloader after "doping"; otherwise, you won't be able to load the System Menu. Instead, boot HBC through Preloader to reinstall it. What is USB Loader? USB Loader is an application for the Nintendo Wii which allows you to to install and load your backup ISO game files to/from a USB storage device. It also allows you to create such backups straight from the original DVD, or you can put ISO files which you have backed up to your computer onto your USB drive and load them from there. This guide will prepare your Wii to use USB Loader GX , which will launch both the USB drive and burned DVD-R discs. What if I just want homebrew? If you don't want to launch backup games and just want to enjoy the world of homebrew, homemade games and applications for the Wii, then you only need to follow steps 2 through 4; it couldn't be simpler. -

This high degree privileges through a process called rooting. of customization enabled by a process called rooting, where the As our main contribution we propose a method for remote users escalate their privileges to those of the operating system, rooting detection in wireless tethering networks provided by introduces security, data integrity and privacy concerns. Several rooting detection mechanisms for Android devices already exist, an Android device. Such networks define a special case of aimed at different levels of detection. This paper introduces wireless networks, as all communication is routed over the further strategies derived from the Linux ecosystem and outlines device offering the hotspot, and can thus be manipulated by their usage on the Android platform. In addition, we present said device.

Android Malware Detection Via (Somewhat) Robust Irreversible Feature Transformations

Citation information: DOI 10.1109/TIFS.2020.2975932, IEEE Transactions on Information Forensics and Security IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY 1 Android Malware Detection via (Somewhat) Robust Irreversible Feature Transformations Qian Han1, V.S. Subrahmanian1 and Yanhai Xiong1 1Department of Computer Science and the Institute for Security Technology and Society Dartmouth College, Hanover, NH 03755, USA As the most widely used OS on earth, Android is heavily targeted by malicious hackers. Though much work has been done on detecting Android malware, hackers are becoming increasingly adept at evading ML classifiers. We develop FARM, a Feature transformation based AndRoid Malware detector. FARM takes well-known features for Android malware detection and introduces three new types of feature transformations that transform these features irreversibly into a new feature domain. We first test FARM on 6 Android classification problems separating goodware and “other malware” from 3 classes of malware: rooting malware, spyware, and banking trojans. We show that FARM beats standard baselines when no attacks occur. Though we cannot guess all possible attacks that an adversary might use, we propose three realistic attacks on FARM and show that FARM is very robust to these attacks in all classification problems. Additionally, FARM has automatically identified two malware samples which were not previously classified as rooting malware by any of the 61 anti-viruses on VirusTotal. These samples were reported to Google’s Android Security Team who subsequently confirmed our findings.
