Recently Mobile Learning (M-Learning) has attracted much attention. Due to advantages of SMS
(Short Messaging Service) on mobile phones we present a safe and protected method for taking
multiple-choice quizzes by using the SMS on mobile phones in this paper. In this method questions
of quiz are sent to students along with their answers through some SMS messages. The students
will receive their grades immediately after answering the questions and this grade is also sent to
the instructor or professor along with the student's answers through an SMS Picture Message.
Answers of questions and the student's grade are hidden in SMS picture message through
stenography and then they are sent. The concerned data will be destroyed within the image after
they are extracted from image in order to improve security and to eliminate the possibility of
cheating. The instructor of lessons can improve his next quizzes through studying and investigating
students' grades and their given answers. This method has been implemented using J2ME
programming language on a Nokia 6230i mobile phone.
