A New Visual Cryptography-Based QR Code System for Medication Administration

A Zero-Watermark Scheme for Identification Photos based on QR Code and Visual Cryptography

This paper proposes a zero-watermark scheme for identification photos based on QR code and visual cryptography. The method makes no changes to original images while embedding the QR code watermark. In order to ensure the security, we use Arnold transformation to scrambling the watermark. In the scheme, we use discrete wavelet transform and matrix norm computing to generate the invariant feature...

Anti-Phishing framework based on Extended Visual Cryptography and QR code

Nowadays Online transactions are become very common and there are various attacks occur behind this. In these types of various attacks, phishing is very common attack. For detecting this attack various anti-phishing mechanisms are used. Propose a new authentication scheme for se-cure OTP distribution in phishing website detection through EVC and QR codes. The Website Detection using extended vi...

A cloud medication safety support system using QR code and Web services for elderly outpatients.

BACKGROUND Drug is an important part of disease treatment, but medication errors happen frequently and have significant clinical and financial consequences. The prevalence of prescription medication use among the ambulatory adult population increases with advancing age. Because of the global aging society, outpatients need to improve medication safety more than inpatients. OBJECTIVE The elder...

A QR Code-based Indoor Navigation System Using Augmented Reality

A Visual Cryptography based system for sharing multiple secret images

A Visual Cryptography (VC)-based system for sharing multiple secret images is proposed. Several weighted transparencies are generated so that people can reveal multiple secret images by stacking qualified subsets of some transparencies together. The transparency with relatively larger weight decides which secret image will be revealed. The proposed method has the following characteristics: deco...
