REPORT DIGITAL SIGNATURE(C.S. & I.T)

In today's commercial environment, establishing a framework for the authentication of computer-based information requires a familiarity with concepts and professional skills from both the legal and computer security fields. Combining these two disciplines is not an easy task. Concepts from the information security field often correspond only loosely to concepts from the legal field, even in situations where the terminology is similar. For example, from the information security point of view, "digital signature" means the result of applying to specific information certain specific technical processes described below. The historical legal concept of "signature" is broader. It recognizes any mark made with the intention of authenticating the marked document. In a digital setting, today's broad legal concept of "signature" may well include markings as diverse as digitized images of paper signatures, typed notations such as "/a/Abb SSh," or even addressing notations, such as electronic mail origination headers.
From an information security viewpoint, these simple "electronic signatures" are distinct from the "digital signatures" described in this tutorial and in the technical literature, although "digital signature" is sometimes used to mean any form of computer- based signature. These Guidelines use "digital signature" only as it is used in information security terminology, as meaning the result of applying the technical processes described in this tutorial.
To explain the value of digital signatures in legal applications, this tutorial begins with an overview of the legal significance of signatures. It then sets forth the basics of digital signature technology, and examines how, with some legal and institutional infrastructure, digital signature technology can be applied as a robust computer-based alternative to traditional signatures.

CHAT MESSENGER(IT & CS)

Chat messenger is a standlone application that is made up from the combination of two-application, server application (which runs on server side) and client application (which runs on client side). This application is using for chatting in LAN. To start chatting you must be connected with the server after that your message can broadcast to each and every client.
For making this application we are using some core java features like swing, collection, networking, I/O Streams and threading also. In this application we have one server and any number of clients (which are to be communicated with each other). For making a server we have to run the MyServer.java file at any system on the network that we want to make server and for client we have to run MyClient.java file on the system that we want to make client. For running whole client operation we can run the Login.java.
We can understand Chat Messenger application by following steps :
•Features and Limitations of the Application
•Server Side Application
•Client Side Application

Security System at home door and security lock

Overview:
The security is what a person expects from a home, this project was designed keeping this particular aspect in mind. The security system is made full proof to the maximum extent possible.
As the person is authenticated a signal can be given to the electric door lock system which can be actuated to automatically opening and closing the door. As the person is authenticated a door will automatically open for some set time delay and will be closed automatically after a particular time delay is over.
There is a large scope in future enhancements that can be provided along with this project like actuating a red glow on led on sensing the brute force.

• Problem and motivation:
1. This project is compatible in windows 98 only.
2. When the correct code is written in C language.
3. Wrong connection of the circuit may not provide a full security lock.
4. If wrong code is being entered, relay will get blocked and user has to wait for few seconds to enter the code again.

Approach and goal of this project: This project can be used for security purpose at home or at any place. In the given project, the two IR sensor circuits consist of 555 timer monostable modes as detecting circuit, will be attached at the entry/ exit door. The parallel port of PC get the data inputs from this, and according to the software, it counts the entry of each person at the door and also take the data reading for exits. The PC provide data outputs to the port to activate the devices to be switched with it. The 4-8 devices can be controlled with the system.
