  Parents are always worried about the wellbeing of their children. As per the
Statistics Report 2017 by Missing Children Europe Organization, a child is
reported missing every 2 minutes. Due to the imminent threat, parents are prone
to buy their children mobile phones to keep in touch with them. However, giving
a Mobile phone to a child can cause issues including cyber bullying, improper
use of social networks, access to mature age and illicit content on the
internet and possibly, phone theft. As an effort to tackle some of those
issues, this paper proposes a solution which enables parents to call, locate
and track their children using a child-friendly mobile device. The common
scenario the device would come to play is in enhancing the safety of a child
who would travel alone on a typical route; for instance a child who walks from
home to school and back. The device can be calibrated to keep track of a
typical route of travel. Then, if the device de-tects some deviation from the
usual route, it would trigger a notification to parents. A probability matrix
based nov-el algorithm is introduced to detect route deviation. De-sign details
of the mobile device, along with the details of the route deviation detection
algorithm are presented in this paper.
