| Summary: Our thesis focuses on the planning and implementation of a QR code-based
encryption and decryption system for triangular pure mathematics issues. The encoding stage begins with an event of a context-free synchronic linguistics to explain triangular issues during a formal language. The geometric descriptions of triangles are then encoded employing an ancient cryptography formula and the corresponding QR code is generated within the cryptography stage. Then the QR code is decrypted and a programmed that is mechanically created by the JavaCC program is used to analyze and show the related problem graphically. The developed system provides QR code reader like tool and presents in a chic way to be able to show mathematical issues on various devices simply. With such a tool, the full queries of associate examination is encoded in QR code and hold on in smaller sizes. This is able to considerably increase the protection of exams and reduce question data, which might be notably transmitted on smartphone, in small size.
Key words: Security, geometry, grammar, encryption, QR-code, geometry. |
