Abstract :
Nowadays a great deal of information is circulated through the Internet. Some of it exclusively belongs to a special group of people and requires protection and safeguarding against unauthorized access. To this end some systems called HIP (human interactive proofs) have been introduced to tell humans and computers apart or various groups of people apart. In this paper, a new method for telling users apart by help of showing picture of a multiple-choice question has been presented. This multiple-choice question is related to some protected information in the field of user´s profession. Since picture of question is viewed the computer cannot answer it. On the other hand, only experts and professional people or people related to the concerned subject can answer the question and have access to information because of professional nature of the question (for example a medical question). This project has been implemented by PHP scripting language.
