Securing and hiding personal confidential information has become a challenge in these modern days. Due to the lack of security and confidentiality, there are chances that forgery of the confidential information or unauthorized access of a system can cause a big margin loss to a person or a system.

Similarly, confidential information can also be kept securely hidden and used to meet a specific purpose like getting access privilege of a secured system and the system can validate the confidential information by checking whether the person is authorized or the information is valid. QR codes are being used increasingly to share data for different purposes. Information communication, QR code is important because of its high data capacity. However, most existing QR code systems use insecure data format and encryption is rarely used. A user can use secure QR code technology to keep information secured and hidden.
