Residential access control system using QR code and the IoT

A QR Code-based Indoor Navigation System Using Augmented Reality

neural classifier ensemble using error-correcting output codes: access control application

abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...

Tsunami warning system using of IoT

Abstract   Today, the world has reached a new nature with advances in science. The Internet of Things is a technology that can connect all objects in different fields through the Internet. Any unforeseen event that destroys economic, social and physical capabilities and inflicts human and financial losses is known as a natural disaster, such as a tsunami. IoT-based tsunami forecasting system ...

QR Code Steganography

QR codes, also known as matrix codes, are basically two dimensional barcodes embedded with data that can be decoded quickly for information. In this work, we present a novel use of QR codes. We show that QR codes can be used for covert communication using steganography. We also show in complete detail how to build QR code symbols with a hidden payload and how to extract this hidden information ...

Artistic QR Code Embellishment

A QR code is a two-dimensional barcode that encodes information. A standard QR code contains only regular black and white squares, and thus is unattractive. This paper proposes a novel framework for embellishing a standard QR code, to make it both attractive and recognizable by any human while maintaining its scanability. The proposed method is inspired by artistic methods. A QR code is typical...
