    Student thesis: Bachelor


    Quick Response code opens possibility to convey data in a unique way yet insufficient prevention and protection might lead into QR code being exploited on behalf of attackers. This thesis starts by presenting a general introduction of background and stating two problems regarding QR code security, which followed by a comprehensive research on both QR code itself and related issues. From the research a solution taking advantages of cloud and cryptography together with an implementation come after. We also give an objective evaluation on the outcome in comparison to existing QR products. They are based on the purpose of enhancing QR code security and aim to interpret how we have tackle the specified problems meanwhile to suggest possible further work for bringing security of QR code to a higher level.
