Abstract
Today, we are living in a technological world that streamlines our operations with a single click, making functions easier and more comfortable for users. One of the applications prevalent today is the hand phone, which offers enormous advantages and flexibility to users' lifestyles. It allows users to access information easily and conveniently, providing solutions to their needs. In addition to communication, hand phones serve various day-to-day functions such as browsing, financial transactions, health monitoring, and more, tailored to the user's preferences. These devices are capable of performing both character based and picture-based operations. In financial transactions, one of the security applications is undersized text-based correspondence. Through this, users receive one-time authentication services to complete desired operations. This not only enables users to complete specific tasks but also ensures that only authenticated individuals can perform particular operations. However, text-based communication is susceptible to hacking. In the proposed model, instead of character based authentication, users will receive picture-based authentication, hidden within the general message. To perform these types of operations, the technique of establishing hidden communications, called secret writing, is proposed here. It will overcome current methods and mitigate many security threats effectively.
