Information authentication using photon-counting double-random-phase encrypted images.
Photon-counting imaging is integrated with optical encryption for information authentication. An image is double-random-phase encrypted, and a photon-limited encrypted image is obtained. The photon-counting encrypted image is generated with few photons and appears sparse; however, we show that it has sufficient information for decryption and authentication. The decrypted image cannot be easily ...
متن کاملThe Impact of Using Quick Response Codes on Educational Motivation
The purpose of this research is to investigate the effect of technology of Quick Response Codes in education. Accordingly, a case study was answer the question "Does using quick response codes effect students' academic motivation?" The statistical population consisted of students from Islamic Azad University in 2016-2017. They were randomly divided into experimental and control groups. Experime...
متن کاملAnnotation of the medical images using quick response codes
The article proposes a novel annotating method of sufficient capacity and intended not only on-line but for off-line using for information preservation all advantages of two-dimensional barcodes. The semantic annotations are embedded directly into the reasonably chosen area of the image and bound by spatial identifiers with corresponding regions. The embedding method deals with the different qu...
متن کاملImproving security of double random phase encoding with chaos theory using fractal images
This study presents a new method based on the combination of cryptography and information hiding methods. Firstly, the image is encoded by the Double Random Phase Encoding (DRPE) technique. The real and imaginary parts of the encoded image are subsequently embedded into an enlarged normalized host image. DRPE demands two random phase mask keys to decode the decrypted image at the destination. T...
متن کاملA Secure Method for Signing in Using Quick Response Codes with Mobile Authentication
The emerging threats to user privacy over the internet are increasing at an alarming rate. Signingin from an unreliable terminal into a web account may result in compromising private details of a user such as username and password, by means of keylogger software. Such software are capable of recording keystrokes secretly, via covert channels without the knowledge of the user. In this paper we p...
