The use of the keywords.

The key words are of great importance because they are used by search engines when indexing articles. That’s why the authors must have the key words in the title and the abstract of the article. The readers also use the key words in their search. It is recommended that the key words should not be repeated more than 3 times in the abstract.

Exercise I

ABSTRACT

Distributed object technology... object oriented programming even more powerful and efficient by making use of the objects that are available on different systems connected on a heterogeneous network, in addition to the locally defined objects. Wide range of hardware platforms and variety of operating systems... inter-connected at the software level and... a more robust and comprehensive solution for today’s Internet driven businesses. Internet itself... an important role as a backbone for this technology. As the scope of the application code... to single source, platform or language, maximum attention... to the security of the applications. The objective of this paper... to give a brief introduction to distributed object technology and an overview of security features available in Microsoft.NET and CORBA. The paper... the architecture of.NET and... some of its key security concepts like Security Policy, Code Access Security, Role Based Security, Verification and Stackwalk. It also... CORBA and its security concepts like CORBA Security Services, Security Specifications, Security Policy, Domain Access Policy and Delegation. The paper... by explaining the way in which some key security concerns... in.NET and CORBA.

Abstract

Visual Cryptography is a special type of encryption technique to obscure image-based secret information which can be decrypted by Human Visual System (HVS). This cryptographic system encrypts the secret image by dividing it into n number of shares and decryption is done by superimposing a certain number of shares(k) or more. Simple visual cryptography is insecure because of the decryption process done by human visual system. The secret information can be retrieved by anyone if the person gets at least k number of shares. Watermarking is a technique to put a signature of the owner within the creation. In this current work we have proposed Visual Cryptographic Scheme for color images where the divided shares are enveloped in other images using invisible digital watermarking. The shares are generated using Random Number.

Task 1. Make up the heading of the abstract using the words:
