Authentication and Protection for Medical Image

2010
This paper proposes a method to authenticate and protect medical images, especially in the region of interest (ROI). The ROI of a medical image is an important area during diagnosis and must not be distorted during transmission and storage in the hospital information system.

Image Secret Sharing in Stego-Images with Authentication

2013
Recently, a polynomial-based (t,n) image sharing and hiding schemes with authentication was proposed to hid n shares of a secret image into n ordinary cover images and form n stego-images that can be transmitted securely. But each stego-image of all existing method should be expanded to 4 times of the secret image.

User Authentication Based on JPEG2000 Images

2006
The problem of user authentication is particularly interesting for increasing information security on Internet based application. The more used authentication systems are based on alphanumeric passwords and their main weak point is the difficulty to remember them.

Visual Image Authentication

AHFE International, 2022
Malware plays a critical role in breaching computer systems. Cybersecurity research has primarily focused on malware detection. Detection methods are currently up against fundamental limits in theoretical computer science. The purpose of visual image authentication is to create Artificial Intelligence (AI) problems that are easy for humans to ...

A New Image Content-Based Authenticity Verification Procedure for Wireless Image Authentication Scheme

2010
In this paper, we proposed a new image content-based authenticity verification procedure for wireless image authentication scheme. The existing image content-based authentication procedure for wireless image authentication scheme has the following shortcomings: 1) High computational cost and 2) Low performance.

IMAGE AUTHENTICATION BASED ON FRACTAL FEATURES

Fractals, 2008
In this paper, the fractal features of natural images are used to construct an image authentication scheme, which can detect whether an image is maliciously tampered (cutting, wiping, modification, etc.) or not and can even locate the tampered regions.

Flexible authentication of images.

2003
In this paper, we propose a novel authentication method for digital images that achieves fine authenticating granularity (e.g., block-level granularity). Its appealing flexibility lies in the fact that with only one piece of authenticating data (e.g., digital signature or message authentication code) spanning all blocks, each block can be independently
