Attendance is something that must be done by students. In the attendance process, SMPN 3 Terara still uses manual method. Therefore, we need a student system can collect and store data so it processed quickly, efficiently accurately. One of technologies currently developing QR Code, Code very much needed because its ability to larger provide fast accurate services. things support author in desi...

Visual cryptography (VC) is a distinct type of secret sharing scheme which hides secret images in share images such that, when the shares are superimposed, a hidden secret image is revealed. It does not require the complex computational method to decode the secret information. The paper proposes a novel Quick Response (QR) code authentication system using Visual Cryptography. The passwords for ...

This paper proposes a challenge-response authentication system for web applications called Snap2Pass that is easy to use, provides strong security guarantees, and requires no browser extensions. The system uses QR codes which are small two-dimensional pictures that encode digital data. When logging in to a site, the web server sends the PC browser a QR code that encodes a cryptographic challeng...

In dieser Arbeit präsentieren wir die Entwicklung und Implementierung eines Umfragetools für Lehrveranstaltungen: das MobileQuiz. Im Vergleich zu anderen Umfragesystemen sind für die Durchführung einer Umfrage keine technischen Vorbereitungen notwendig. Die Anwendung ist nahtlos in die bereits bestehende Infrastruktur der Universität integriert, nutzt die mobilen Endgeräte der Studierenden als ...

In this paper the author present a new technique of using QR Codes (commonly known as ‘Quick Respond Codes’) in the field of Cryptography. QR Codes are mainly used to convey or store messages because they have higher or large storage capacity than any other normal conventional ‘barcodes’. In this paper the primary focus will be on storing messages in encrypted format with a password and send it...

This paper describes how videos can be implemented into printed photo books. More than half of the consumers take videos with DSCs, the other half with camcorders, smartphones and other devices. Therefore consumers making photo books are a great target group to offer a service implementing videos. Using the CEWE PHOTOBOOK software a consumer can select scenes (frames) of the video and have it p...

Sports are a key part of cultural identity, and it is necessary to preserve them as important intangible Cultural Heritage, especially the human motion techniques specific to individual sports. In this paper we present a method for extracting 3D athlete motion from video broadcast sources, providing an important tool for preserving the heritage represented by these movements. Broadcast videos i...

Xerox DataGlyph technology is a 2-D matrix barcode encoding which combines relatively high data density with an error correction scheme and an unobtrusive format. Some of the more exciting applications proposed for this technology involve the decoding of unconstrained camera images of DataGlyphs. This paper details a set of grayscale methods including steered gradient filters and the Radon tran...

The application of QR codes in laboratory management is an increase, but the study its use physics equipment storage rarely done. There are numerous various stored laboratory. Well-organized with QR-code installment cabinet should be a big consideration to assist users at trace and emplace appropriate. This aims develop designing layout cabinet. development refers research methods. two main foc...
