Modern applications of QR-Code for security

With the massive growth of technology, QR Code has a wide range of applications. QR Code is a 2D matrix Bar Code where the information is stored both in horizontal and vertical dimensions. QR Code can hold a larger amount of data in a smaller space, performs reliable error-correction at higher speed and has faster response time. Increasing use of smart phones among all age groups made accessing QR Code easier by providing end-user content, including Web links, personal details etc. QR Code is versatile and is used in diverse research fields such as online banking, attendance management, health care, help visually impaired people, security applications such as different kinds of cryptography and steganography as well. Secure authentication, is achieved using data-hiding algorithms with the embedded QR Code. This paper highlights security aspects handled by QR Code in many applications and further directs to secured transportation of the data using SQRC which has its real time applications like vehicle and identity verifications.
