  • Recently, the number of attacks by malicious application has significantly increased, targeting Android-platform mobile terminal such as Samsung Galaxy Note and Galaxy Tab 10.1. The malicious application can be distributed to currently used mobile devices through open market masquerading as an normal application. An attacker inserts malicious code into an application, which might threaten privacy by rooting attack. Once the rooting attack is successful, malicious code can collect and steal private data stored in mobile terminal, for example, SMS messages, contacts list, and public key certificate for banking. To protect the private information from the malicious attack, malicious code detection, rooting attack detection and countermeasure method are required. To meet this end, this paper investigates rooting attack mechanism for Android-platform mobile terminal. Based on that, this paper proposes countermeasure system that enables to extract and collect events related to attacks occurring from mobile terminal, which contributes to active protection from malicious attacks.

  • The purpose of this study is to analyze the trends of wearable keywords using text mining methodology. To this end, 11,952 newspaper articles were collected from 1992 to 2019, and frequency analysis and bi-gram analysis were applied. The frequency analysis showed that Samsung Electronics, LG Electronics, and Apple were extracted as the highest frequency words, and smart watches and smart bands continued to emerge as higher frequency in terms of devices. As a result of the analysis of the bi-gram, it was confirmed that the sequence of two adjacent words such as world-first and world-largest appeared continuously, and related new bi-gram words were derived whenever issues or events occurred. This trend of wearable keywords will be useful for understanding the wearable trend and future direction.

  • Mobile operating systems have been typically classified into Apple and Android. Samsung showed its own new mobile OS developing Tizen based on Linux kernel. Mobile operating system has developed a technology using low-power by itself because of the limitation of capacity of battery, a feature of mobile. Samsung Tizen OS has a low-power technology called Power Manager controling LCD states as users'inputs or time-out events occur. However, if users'input occurs frequently, energy consumption jumped before-and-after users'input because CPU clock is increased rapidly due to overhead increase for frequent LCD state changes. This paper proposes a mechanism to reduce the overhead for LCD state changes, when user's input is frequent, by adding a new state to the Power Manager the current Tizen OS is using. We have implemented the proposed mechanism at Tizen phone kernel layer in this paper and experimented the mechanism according to users' LCD touch inputs. The experiment shows that it is possible to decrease energy by reducing the CPU clock increase according to the frequent user's inputs.
