    An Android Application to Secure Text Messages
    (IEEE, 2017) Demirol, Doygun; Das, Resul; Tuna, Gurkan
    For mobile phone users, short message service (SMS) is the most commonly used text-based communication type on mobile devices. Users can interact with other users and services via SMS. For example, users can send private messages, use information services, apply for a job advertisement, conduct bank transactions, and so on. Users should be very careful when using SMS. During the sending of SMS, the message content should be aware that it can be captured and act accordingly. Based on these findings, the elderly, called as Silent Generation which represents 70 years or older adults, are text messaging much more than they did in the past. Therefore, they need solutions which are both simple and secure enough if there is a need to send sensitive information via SMS. In this study, we propose and develop an android application to secure text messages. The application has a simple and easy-to-use graphical user interface but provides significant security.

    A Simple Logging System for Safe Internet Use
    (IEEE, 2017) Demirol, Doygun; Tuna, Gurkan; Das, Resul
    Although the Internet offers numerous advantages, it raises many information security risks, especially against young people and children, who are today amongst the largest user groups of mobile and online technologies all around the world. Therefore, to empower and protect Internet users, it is necessary to develop proper strategies and tools to encapsulate their needs, and identify and prevent all types of the information security risks that may arise during the use of the Internet. In this study, a tracking system to ensure the safe use of the Internet is proposed. Considering the distribution of its potential users, the system has an easy-to-use graphical user interface. By recognizing dangerous web sites and IP addresses, the proposed system blocks access to those sites and this way provides reliable Internet access to its users. During the Internet access, it analyzes accessed IP addresses and port numbers in terms of access type and time and informs the user of the corresponding port numbers which must be closed for safe Internet access. Moreover, by continuously checking the host redirection file of the computer it runs on, it identifies redirections from web addresses to specific IP addresses and this way provides protection against phishing attacks which are becoming one of the most common Internet threats. Although the proposed system is a simple application since it is an open source, freeware application designed for children, it can be improved to consider more sophisticated attack types.
