STTEGNOGRAPHY FOR AUDIO,VEDEO,IMAGE

Introduction

 Steganography is a useful technique for hiding data behind the carrier file such as image, audio, video etc. and that data securely transfer from sender to receiver. The cryptography is also another technique which is used for the protecting information. The Combining encryption methods of cryptography and steganography enables the user to transmit information which is masked inside of a file in plain view. This will provide more security to transferring data. This paper provides a general overview of Steganography techniques in which Text, Image Audio and Video Medias used for the information hiding behind channels. Also the Cryptography will be applied on the information for the better security. Keywords: Image Steganography, Audio Steganography, Video Steganography, Spatial domain and Transform domain.

The objective of steganography is to hide a secret message within a cover-media in such a way that others cannot discern the presence of the hidden message. Technically in simple words “steganography means hiding one piece of data within another”.Modern steganography uses the opportunity of hiding information into digital multimedia files and also at the network packet level.

Hiding information into a media requires following elements

•The cover media(C) that will hold the hidden data

•The secret message (M), may be plain text, cipher text or any type of data

•The stego function (Fe) and its inverse (Fe-1)

•An optional stego-key (K) or password may be used to hide and unhide the

message.The stego function operates over cover media and the message

Security Levels for Web Authentication using Mobile Phones

Abstract. Mobile phones offer unique advantages for secure authentication:they are small and portable, provide multiple data transfer channels,and are nearly ubiquitous. While phones provide a flexible and capable platform, phone designs vary, and the security level of an authentication solution is influenced by the choice of channels and authentication methods. It can be a challenge to get a consistent overview of the strengths and weaknesses of the available alternatives. In this paper weprovide a method for evaluating and designing authentication solutionsusing mobile phones. The method also considers availability and usability,which are often overlooked factors. The goal is to help developers tocreate secure authentication, considering the user's priorities on security,availability and usability.

BUG TRACKING SYSTEMS WITH GAME MECHANISMS

Low bug report quality and human conflicts pose challenges to keep bug tracking

systems productive. This work proposes to address these issues by applying game

mechanisms to bug tracking systems. We investigate the use of game mechanisms in Stack

Overflow, an online community organized to resolve computer programming related

problems, for which the improvements we seek for bug tracking systems also turn out to be

relevant. The results of our Stack Overflow investigation show that its game mechanisms

could be used to address these issues by motivating contributors to increase contribution

frequency and quality, by filtering useful contributions, and by creating an agile and

dependable moderation system. We proceed by mapping these mechanisms to open-

source bug tracking systems, and find that most benefits are applicable. Additionally, our

results motivate tailoring a reward and reputation system and summarizing bug reports as

future directions for increasing the benefits of game mechanisms in bug tracking systems.

Gas Inventory System

Main aim of Gas Agency Management System project is to create a computerized system for billing and maintaining stock and to increase the efficiency of manual process. Customers will make phone call to the Gas Agencies and give order request then gas agencies will deliver the gas cylinders to their address based on their demand and previous delivery date. The customer’s name, address and stock details are stored in a database. A customer’s order for gas cylinder can be accepted only after completing a certain period from the previous delivery. This makes billing for customer is easier and based on the customer’s database calculation of bill to the customer is done.

The bill rate and capacity of gas cylinder can be easily maintained and charged accordingly using this system. Customer’s details are stored in booking register including booking number when he books gas cylinder.

Customer will call and give order request to gas agencies. Then Gas Agencies deliver the gas cylinders to their address based on their demand and previous delivery date. Customer’s details like name, address and stock details are stored in a database. Based on this the billing for a customer is done. A customer’s order for gas cylinder can be accepted only after completing a certain period from the previous delivery.

Availability of gas cylinders in gas agency can be checked using the stock register to determine the number of refilled, filled, empty, defective & price of refill.

Intranet Mailing SystemThis system facilitates mailing among users of an Intranet. Now-a-days organizations are

growing fast and are increasing in size also. So these organizations are divided into departments.

In the fast growing world the information is needed as fast as possible. This can be accomplished

by passing the information quickly. Quick passing of mails is not possible in manual systems.

This is because the information is passed through persons of one department to another

department. This leads to the inconsistency and delay in delivering information. So we need a

system which is both quick and accurate. This can be achieved by developing a web-based

Intranet Mailing System.

As organization grows in size in terms of departments and functionalities, it requires a

quick and efficient system to achieve instant communication b/w employees of same department

or b/w departments. The proposed system “Intranet Mailing System” serves organization’s needs

in a consistent and transparent manner. It should cater the needs of information sharing. It allows

the users to exchange their views thru mails and send electronic files thru attachments. It should

have all traditional things such as sent items, inbox, drafts etc. The users are allows to send mails

to multiple users using to, cc and bcc too. Thus the system caters spontaneous needs of the

organization.

Agro Service Management System

The real problem of the growing Agro service is monitoring their business activities. In

the existing system cannot provide accurate information about the business process. To avoid

this sort of situations the work of the whole trading company is computerized by this project.

The computerization helps employee’s access real-time “paperless” tracking of every

transaction and for customers we will deliver the reports of agro products in different soil in easy

manner through this we can deliver the perfect matching product for customer land.

This system helps in minimizing the manual work of maintenance and fast accessing the

work in data maintenance. All the details are stored by separate tables in this project to cut short

the paper work. Customers numbers are improve on the basis of on-time sales, service,

scheduling and delivery.

In the competitive world we must watch the every nook and corner of business

transaction. The existing system cannot provide this facility. So this project is developed “Agro

Service Management System” with an aim of enhancing the business activities.

Retail_Inventory_Management_System

Just like any investment in business, inventory needs to serve the purpose of maximizing profit.

However, in many cases inventory has turned into a major cash flow constraint thus making it

necessary to optimize inventory using analytical and statistical methods in an integrated

approach.

One of the biggest challenges in optimizing inventory is the fact that it is merely an output of

many inter-organizational processes. All too often organizations attempt to lower inventory using

non-analytical approach which lower service levels.

Although counterintuitive, it in fact is possible to reduce inventory while improving

service levels simultaneously using our proven inventory management methodology.

Our inventory management methodology attacks inventory from two directions:

* Optimizing inventory levels while viewing the existing order fulfillment process as a given

constraint

* Changing the fundamental order fulfillment process across the entire system

Most clients find this two-step approach of significant value. During the first step cash can

be made available quickly and success is immediately generated. Step two is used to generate

breakthrough business results and provide a robust order fulfillment process that will be able to

perform at lower inventory levels while providing extraordinary service levels.
