Surya Prasath. Information security using image steganography is the process of concealing secret information within an image. The conventional methods are static approaches having fixed capacity in term of embedding rate. To solve the problem of static behavior and fixed capacity, we proposed a method that is dynamic approach and increased capacity for embedding rate. Novel algorithm can be used by the data storage industry to design new data storage devices. Other possible applications of this research work will be its usage in other areas such as Watermarking, Document Tracking Tool, Document Authentication Tool, and General Communication etc. Experimental results demonstrate that our proposed steganography algorithm produces the best performance among state-of-the-art algorithms in evaluation of subjective visual assessment as well as objective error metrics. Steganography is paradigm that conceals the secret data into some digital medium in such a way so its existence cannot be noticed by human perception [], see the study [10] for a recent review. With the rapid advancement and use of internet as communication channel, steganography has become an important and valuable tool for secure communication between sender and recipient without the snooping of third person. At the beginning the most known processes of steganography, named as substitution and matching processes, were used for secret communication and many other applications like watermarking, document tracking, document authentication etc.

Discover all of them and learn how to join. RDA Outputs are the technical and social infrastructure solutions that enable data sharing, exchange and interoperability. Discover them all. This whiteboard is open to all RDA discipline specialists willing to give a personal account of what data-related challenges they are facing and how RDA is helping them. Find your discipline. Working Groups are short-term 18 months and come together to develop and Asseswment data infrastructure, which could be tools, policy, practices and products that are adopted and used by projects, organizations, and communities.

Embedded within these groups are individuals who will use the infrastructure and help in making it broadly available to the public. Interest groups are open-ended in terms of longevity. They focus on solving a specific data sharing problem and identifying what kind of infrastructure needs to be COM100033.

Interest Groups can identify specific pieces of work and start up a Working Group to tackle those.

The goal of the Agrisemantics WG is to gather community-based requirements and use cases for an infrastructure that supports appropriate use of semantics for data interoperability, with special focus on agriculture. The scope of the WG covers data sources from research and scholarly communication.

Status and Current Activities

Within this domain obstacles for wider application of brokering techniques are:. The aim of this Working Group WG is to develop synergies between existing education and training activities and agricultural science needs by performing a landscape assessment to identify existing gaps and training requirements within the Interest Group on Agricultural Data IGAD WGs related. A particular focus will be on sharing knowledge about training FINAL COM10003 Assessment 3 Honeyman and technologies, reducing digital divides so that researchers and practitioners in developing countries can also benefit. It's recommendations are based upon on 1 timestamping and versioning changes to evolving data and 2 identifying arbitrary subsets by assigning PIDs to the queries selecting the according subsets and are applicable across all types of data, such as e.

The efficient and effective reuse of data requires that users, be they humans or machines, FINAL COM10003 Assessment 3 Honeyman able to find and access data at fine levels of granularity. The Data Granularity Working Group aims to better understand and address the existing needs and landscape for data granularity practices, in areas such as data product collection, description, access, and citation, amongst others. It will do so by both leveraging existing RDA work related to granularity and gathering new information.]
