Resumen

In recent years, the use of technology has increased rapidly as many people send a lot of text or image information every day, and also sometimes in schools or different study centers, teachers need to send private information such as grades to their students or their parents. In addition, this information is generally for a particular student, so it is necessary to implement some tool that helps them send secure information through to the Internet. And in these cases, encryption plays a fundamental role in security. On the other hand, the quick response (QR) code is used widely to provide easy access to information, and also it could be applied for secured communications using different devices to access the internet. For that reason, this paper proposes a new method to send secure information about students’ grades using a QR code, and in order to keep the information safe, we have proposed to use 3 × 3 patterns to represent any number and the information into the QR code which has been distributed in random positions whose average variation percentage was 1.142857143, which is within the margin of error allowed in QR codes. Finally, the experiments have demonstrated that the proposed method can achieve successful results and each student with the correct password can be able to retrieve only their grades.
