Quantization-based image authentication scheme using QR error correction
Image authentication, which is provided with capabilities of tamper detection and data recovery, is an efficient way to protect the contents of digital images. Vector quantization (VQ) is a data compression method. A VQcompressed code is not only a significant image authentication feature but also applicable in restoring possibly damaged pixels. However, if an image is tampered with, the necess...
متن کاملImage authentication using LBP-based perceptual image hashing
Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...

Chuang This paper proposes an image authentication scheme which detects illegal modifications for image vector quantization (VQ). In the proposed scheme, the index table is divided into non-overlapping index blocks. The authen...
متن کامل2CAuth: A New Two Factor Authentication Scheme Using QR-Code
Password based schemes has been the standard means of authentication over decades. Enhancements use entities like ownership (something one possess), knowledge (something one knows), and inherence (something one is) as first factor and mobile phones as token less second factor, in combinations, to offer different levels of security assurances, trading off usability. In this paper we present ‘2CA...
متن کامل3CAuth - A Novel Multi-Factor Authentication Scheme Using QR-Code
A multi factor authentication scheme called ’3C-Auth’ is proposed in this paper. The scheme carries out a comprehensive authentication process using the smart card, secret-pin, registered finger print, and registered mobile number of the user. The user’s password is neither transmitted in plaintext form nor revealed to the authentication server. The scheme is shone to be proof against phishing,...
