Image authentication is to protect the image integrity when the digital image is illegally modified. Most of the image authentication schemes proposed so far employed the irreversible data hiding approach to embed the authentication data into the cover images. In this paper, a novel reversible image authentication scheme for digital images is proposed. In the proposed scheme, the authentication...

Security analysis is provided based on tool-sets for content authentication. Given a watermark payload, the watermarking scheme should be. IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY. Tune a robust watermarking scheme to.have been devoted to security analysis in which successful attacks have been. Posed semi-fragile watermark-based authentication systems fail security.In this paper ...

a broadcast authentication protocol enables the receivers to verify that a received packet was really sent by the claimed sender. Data confidentiality, authenticity, integrity, and non repudiation are basic concerns of securing data delivery over an insecure network. Large and distributed systems with time critical applications require immediate and secure authentication of command and control ...

In this paper, we present ThresPassport (Threshold scheme-based Passport), a web-based, distributed Single Sign-On (SSO) system which utilizes a threshold-based secret sharing scheme to split a service provider’s authentication key into partial shares distributed to authentication servers. Each authentication server generates a partial authentication token upon request by a legitimate user afte...

Web authentication that is both secure and usable remains a challenge. Passwords are vulnerable to phishing attacks, while physical tokens face deployment obstacles. We propose to leverage the authentication infrastructure of cellular networks to enhance Web authentication. We design WebCallerID, a Web authentication scheme that uses cell phones as physical tokens and uses cellular networks as ...

Wireless Networks provide more flexibility and connectivity to the users, to be connected with anyone, any time, any where. This feature makes the wireless networks to be wide open to threats and attacks by the intruders. To ensure a reliable and secure wireless environment, suitable authentication protocols have to be employed based on the network infrastructure. The scope of this thesis is to...

In a virtual organization environment, where services and data are provided and shared among organizations from different administrative domains and protected with dissimilar security policies and measures, there is a need for a flexible authentication framework that supports the use of various authentication methods and tokens. The authentication strengths derived from the authentication metho...

Security threats are major barriers in authentication process in Fog Computing. Identification of a user through single signon process like simple password-based authentications are no longer considered secure. Different multi-tier authentication schemes exist in literature that overcome the weakness of single sign-on. This paper surveys state-of-the-art multi-tier authentication techniques, th...

Multi-factor Authentication (MFA) often referred to as Two-factor (2FA), which is a subset of MFA, the practice implementing additional security methods on top standard username and password help authenticate identity user increase data.This chapter will investigate problem with logins, different types authentication, current best for multi-factor authentication interpretations about how techno...

Authentication is the process for identify the correct user or not. The identities enclose mainly the username and passwords for verifying the two entities. The authentication information’s are stored in the form of encryption in a device which is properly registered in the server. At the time of authentication process performs between user and server the intruder can eves-dropping the communic...
