SafeChat: A tool to shield children's communication from explicit messages

Internet, on one hand, is a primary foundation for knowledge acquisition in a child's life. On the other hand, there are many growing exploits over children. Motivated by the rising need to shield children's communication channels from obnoxious sources, this paper proposes a framework named SafeChat. SafeChat is the result of aggregating the context based authentication features of 4-CBAF model and the message encryption features from demonstrated SecureString 2.0. SafeChat intercepts children's communication and eradicates explicit words coming into the children's devices. SafeChat filters explicit words without recognizing their meaning. Such an approach hardens the system against malicious attacks. Furthermore, it secures the communication channels against possible man-in-the-middle attacks by employing an encryption mechanism. In addition, it encompasses the tools to authenticate and authorize communications and allows parents to monitor children communication channels in case an intervention is desirable. SafeChat supports to extend it to incorporate essential features including a facility to censor users through building a social network. Such a social network would allow other children to learn about the users with potential threats.
