Secret Digital Image Sharing Using Natural Image Based VSS Scheme
International Journal of Science and Research (IJSR) ISSN (Online): 2319-7064 Index Copernicus Value (2013): 6.14 | Impact Factor (2013): 4.438 Secret Digital Image Sharing Using Natural Image Based VSS Scheme Pinky .V M. Tech Student, Dept. of Computer Science & Engineering Mount Zion College of Engineering, Pathanamthitta, Kerala, India Abstract: Visual cryptography is a technique of sharing secret images. This technique encrypts a secret image into number of shares. Combining these shares generates the original image and it can be directly recognized by the human visual system. Visual Secret Sharing scheme is a method of distributing and sharing the secret image amongst a set of users. In conventional visual secret sharing scheme, the shares May holding the security parameters for protecting the secret image but it will leads to suffering the problem of transmission risk. This is the main problem in conventional VSS scheme. To solve this problem here introduce a new scheme of secret digital image sharing via natural image based VSS scheme. In this proposed scheme the shares are encrypted by using the strong AES encryption technique after that this encrypted share is embedded into the natural image. For recovering the original image, it is necessary to decrypt the encrypted share. This method not only reduces the transmission risk problem but also enhance the security of the secret image. Keywords: Visual Cryptography, Visual Secret Sharing Scheme, Transmission Risk Problem, Natural Image based VSS scheme, Encryption/Decryption technique. 1. Introduction photographs. In the proposed scheme diverse media is used for sharing digital images.

Image-Based Abuse, Non-Consensual Pornography, Revenge Porn: A Study of Criminalization and Crime Prevention in Australia and England & Wales Majid Yar1 University of Hull, United Kingdom Jacqueline Drew2 Griffith Criminology Institute, Australia Abstract Distribution of nude, intimate and sexualized images of individuals without consent and against the wishes of those individuals whose image has been captured, is of growing concern across the world. Moving from the conceptualization of ‘revenge porn’ in the early 2000’s, through to our more sophisticated understanding of the issues of “image-based abuse” and “non-consensual pornography” this paper considers the broad context of these crimes. The paper draws on the concepts of online misogyny, gender-based victimization, and “toxic masculinity”. The progress towards criminalization of such online abuse, with reference to the recent introduction of new laws in England & Wales and Australia is examined. This shift from voluntary to statutory regulation, and from civil to criminal law remedies has been coupled with new crime prevention and control initiatives that seek to encourage reporting leading to prosecution and educate users and empower victims. -

Ground-Based Photographic Monitoring
United States Department of Agriculture Ground-Based Forest Service Pacific Northwest Research Station Photographic General Technical Report PNW-GTR-503 Monitoring May 2001 Frederick C. Hall Author Frederick C. Hall is senior plant ecologist, U.S. Department of Agriculture, Forest Service, Pacific Northwest Region, Natural Resources, P.O. Box 3623, Portland, Oregon 97208-3623. Paper prepared in cooperation with the Pacific Northwest Region. Abstract Hall, Frederick C. 2001 Ground-based photographic monitoring. Gen. Tech. Rep. PNW-GTR-503. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 340 p. Land management professionals (foresters, wildlife biologists, range managers, and land managers such as ranchers and forest land owners) often have need to evaluate their management activities. Photographic monitoring is a fast, simple, and effective way to determine if changes made to an area have been successful. Ground-based photo monitoring means using photographs taken at a specific site to monitor conditions or change. It may be divided into two systems: (1) comparison photos, whereby a photograph is used to compare a known condition with field conditions to estimate some parameter of the field condition; and (2) repeat photo- graphs, whereby several pictures are taken of the same tract of ground over time to detect change. Comparison systems deal with fuel loading, herbage utilization, and public reaction to scenery. Repeat photography is discussed in relation to land- scape, remote, and site-specific systems. Critical attributes of repeat photography are (1) maps to find the sampling location and of the photo monitoring layout; (2) documentation of the monitoring system to include purpose, camera and film, w e a t h e r, season, sampling technique, and equipment; and (3) precise replication of photographs.
