ADVERTISEMENT MANAGEMENT SYSTEM PROJECT REPORT

1.3 PROCESS DESCRIPTION

The following formula provides a very generic description of the multimedia advertisement pieces of the multimedia advertisement steganographic process:

covermedium + hiddendata + stegokey = stegomedium

In this context, the covermedium is the project report of advertisement system file in which we will hide the advertisement agency hiddendata, which may also be encrypted using the advertisement management system project with java source code stegokey. The resultant file is the project report of advertisement system stegomedium (which will, of course. be the advertisement agency same type of file as the project report of advertisement system covermedium). The covermedium (and, thus, the stegomedium) are typically image or audio files.

CHAPTER 2 OBJECTIVES

2.1 OBJECTIVES

The project has the project report of advertisement system following objectives:

1. To create a tool that can be used to hide data inside a 24 bit color image.

2. The tool should be easy to use, and should use a graphical user interface.

3. The tool should work cross-platform.

4. The tool should effectively hide a message using an image degradation approach, and should be able to retrieve this message afterwards.

5. The tool should take into account the source code of the advertisement management system original content, to theoretically more effectively hide the advertisement agency message.

6. The tool should be able to provide some information as to the java project source code of advertisement management system effectiveness of the multimedia advertisement hiding i.e. it should be able to evaluate the advertisement agency degradation of an image. The analysis used will consist of existing watermarking measures, re- implemented for this tool.

7. The technique should fall under the synopsis of advertisement management system category of Secret Key Steganography -where without the source code of the advertisement management system key the advertisement project documentation hidden message cannot be retrieved.

8. The tool should be able to encrypt the source code of the advertisement management system message before embedding it.

3.1 SUCCESS SO FAR

Up until now, this has proven to be a successful steganographic technique for use in distributing spam and getting around my spam filtering software. At this point in time, spam filtering software is incapable of detecting the advertisement management system project with java source code hidden content and categorizing the advertisement management system project with java source code message as spam om the asp.net source code basis of that content. This success will probably be short lived, however

As mentioned above, cryptography is often used in situations where the advertisement agency existence of the multimedia advertisement message is clear, but the source code of the advertisement management system meaning of the multimedia advertisement message is obscured. In particular, the sender transforms the project report of advertisement system message into a form that (hopefully) only the advertisement project documentation intended recipient of the multimedia advertisement message can decrypt and read.Steganography is often used in situations where the advertisement agency actual existence of the multimedia advertisement message needs to be obscured.

3.3 STEGANOGRAPHY AND CRYPTOGRAPHY CAN BE COMBINED

The message can also be encrypted before it is hidden inside a cover message. This provides a double layer of protection. To begin with, encryption may make the advertisement agency existence of the multimedia advertisement message even more difficult to detect, due to the java project source code of advertisement management system fact that some encryption techniques cause the advertisement agency patterns of the multimedia advertisement characters im the asp.net source code encrypted version to be more random than im the asp.net source code original version. In addition, even if the multimedia advertisement existence of the multimedia advertisement encrypted message is detected, it is unlikely that an eavesdropper will be able to read the advertisement management system message.

3.4 HIDING THE ADVERTISEMENT MANAGEMENT SYSTEM PROJECT WITH JAVA SOURCE CODE MESSAGE

1. This program hides the project report of advertisement system message im the asp.net source code image by doing the advertisement management system project with java source code following:

2. Reducing the advertisement management system project with java source code message to the java project source code of advertisement management system 64-character set beginning with the text ads management space character im the asp.net source code ASCII table. Each character can then be represented by six bits.

3. Decomposing each six-bit character into three groups of two bits each.

4. Replacing the advertisement management system project with java source code two least-significant bits (LSB) im the asp.net source code red, green, and blue values for a given pixel by the advertisement project documentation three groups of two bits. Thus, each pixel can carry one six-bit character

CHAPTER 5 TECHNIQUE USED

5.1 TECHNIQUE USED

Steganographic Techniques used is oncealing data within encrypted data. The data to be concealed is first encrypted before being used to overwrite part of a much larger block of encrypted data. This technique works most effectively where the advertisement agency decrypted version of data being overwritten has no special meaning or use. Each pixel typically has three numbers associated with it, one each for red, green, and blue intensities, and these values often range from 0-255. Each number is stored as eight bits (zeros and ones), with a one worth 128 im the asp.net source code most significant bit (om the asp.net source code left), then 64, 32, 16, 8, 4, 2, and a one im the asp.net source code least significant bit (om the asp.net source code right) worth just 1.

5.2 HOW STEGANOGRAPHY WORKS

Steganography strips less important information from digital content and injects hidden data in its place. This is done over the synopsis of advertisement management system spectrum of the multimedia advertisement entire image. Here's one way it could be implemented:

The following sequence of 24 bits represents a single pixel in an image. Its 3 bytes of color information provide a total of 256 different values for each color (red, green and blue) and thus can represent a total of 16.7 million colors. This particular value displays as a dark green:Now, let's take 11 of these pixels that represent, say, part of a solid-color background. Im the asp.net source code following sequence, the least significant (rightmost) bit of each 8-bit byte has been co-opted to hide a text message—the four characters Aha!—in ASCII binary:

The hidden message occupies 32 of those 264 bits (about 12%) and contains four 8-bit bytes. Im the asp.net source code diagram, each maroon or gold box represents a bit that had to be changed to include the advertisement agency hidden message. Notice that only 15 of 264 bits (less than 6%) had to be changed and only eight of the multimedia advertisement 11 pixels were altered.The two figures below represent the source code of the advertisement management system 11 colored pixels we've been manipulating. The figure om the asp.net source code left is the project report of advertisement system original, unaltered version. The one om the asp.net source code right has been modified.

5.3 ALGORITHM USED

The DES (Data Encryption Standard) algorithm is the project report of advertisement system most widely used encryption algorithm im the asp.net source code world. For many years, and among many people, "secret code making" and DES have been synonymous. DES works on bits, or binary numbers--the 0s and 1s common to digital computers. Each group of four bits makes up a hexadecimal, or base 16, number. DES works by encrypting groups of 64 message bits, which is the project report of advertisement system same as 16 hexadecimal numbers. To do the java project source code of advertisement management system encryption, DES uses "keys" where are also apparently 16 hexadecimal numbers long, or apparently 64 bits long. However, every 8th key bit is ignored im the asp.net source code DES algorithm, so that the source code of the advertisement management system effective key size is 56 bits. But, in any case, 64 bits (16 hexadecimal digits) is the project report of advertisement system round number upon which DES is organized.

CHAPTER 6 MODULES

The project consists of mainly four modules encryption, hide message, retrieve message and decryption. Encryption and hide message form the advertisement Php project modules at the source code of the advertisement management system sender side. retrieve message and decryption form the advertisement Php project modules at the source code of the advertisement management system receiver side

6.1 SENDER SIDE

6.1.1 Encryption

Encryption includes a message or a file encrypting. Encryption involves converting the advertisement management system project with java source code message to be hidden into a cipher text. Encryption can be done by passing a secret key.Secret key can be used for encryption of the multimedia advertisement message to be hidden.It provides security by converting it into a cipher text,which will be difficult for hackers to decrypt. Moreover if the multimedia advertisement message is password protected,then while retrieving message,the retriever has to enter the synopsis of advertisement management system correct password for viewing the advertisement management system project with java source code message.

6.1.2 Hide Message

Hiding message is the project report of advertisement system most important module of steganography.It involves embedding the advertisement management system project with java source code message into the java project source code of advertisement management system cover text. Each pixel typically has three numbers associated with it, one each for red, green, and blue intensities, and these values often range from 0-255.In order to hide the advertisement agency message,data is first converted into byte format and stored in a byte array.The message is then encrypted and then embed each bits into the java project source code of advertisement management system LSB position of each pixel position. The least significant (rightmost) bit of each 8-bit byte has been co-opted to hide a text message.

6.2 RECEIVER SIDE

6.2.1 Retrieve Message

It involves retrieving the advertisement management system project with java source code embed message from the advertisement Php project file independent of the multimedia advertisement file format. Once the advertisement agency message has been retrieved it has to be converted into original message or file.

This can be done by reading the advertisement management system project with java source code embedded data from the advertisement Php project master file. The read data will be im the asp.net source code bytes format. This message has to be converted into the java project source code of advertisement management system suitable output file format.

6.2.2 Decryption

Decryption includes a message or a file decrypting. Decryption involves converting the advertisement management system project with java source code cipher text into decrypted format. Decryption can be done by passing a secret key. Secret key can be used for decryption of the multimedia advertisement message that is hidden. It provides security by converting the advertisement management system project with java source code cipher text, into the java project source code of advertisement management system original data message or file . Moreover if the multimedia advertisement message is password protected, then while retrieving message, the retriever has to enter the synopsis of advertisement management system correct password for viewing the advertisement management system project with java source code message.

CHAPTER 7 JAVA

Java was developed at Sun Microsystems. Work on Java initially began with the text ads management goal of creating a platform-independent language and OS for consumer electronics. The original intent was to use C++, but as work progressed in this direction, developers identified that creating their own language would serve them better. The effort towards consumer electronics led the advertisement management system Java team, then known as First Person Inc., towards developing h/w and s/w for the synopsis of advertisement management system delivery of video-on-demand with Time Warner.

Unfortunately (or fortunately for us) Time Warner selected Silicon Graphics as the project report of advertisement system vendor for video-on-demand project. This set back left the source code of the advertisement management system First Person team with an

interesting piece of s/w (Java) and no market to place it. Eventually, the natural synergies of the multimedia advertisement Java language and the advertisement management system www were noticed, and Java found a market.

Today Java is both a programming language and an environment for executing programs written in Java Language. Unlike traditional compilers, which convert source code into machine level instructions, the Java compiler translates java source code into instructions that are interpreted by the advertisement project documentation runtime Java Virtual Machine. So unlike languages like C and C++, on which Java is based, Java is an interpreted language.

Java is the project report of advertisement system first programming language designed from ground up with network programming in mind. The core API for Java includes classes and interfaces that provide uniform access to a diverse set of network protocols. As the project report of advertisement system Internet and network programming have evolved, Java has maintained its cadence. New APIs and toolkits have expanded the advertisement management system available options for the synopsis of advertisement management system Java network programmer.

7.1 FEATURES OF JAVA

In one of their early papers about the source code of the advertisement management system language, Sun described Java as follows: Java: A simple, object-oriented, distributed, interpreted, robust, secure, architecture neutral, portable, high-performance, multithreaded, and dynamic language. Sun acknowledges that this is quite a string of buzzwords, but the source code of the advertisement management system fact is that, for the synopsis of advertisement management system most part, they aptly describe the advertisement agency language. In order to understand why Java is so interesting, let's take a look at the source code of the advertisement management system language features behind the advertisement management system buzzwords.

■ Object-Oriented

Java is an object-oriented programming language. As a programmer, this means that you focus om the asp.net source code data in your application and methods that manipulate that data, rather than thinking strictly in terms of procedures. If you're accustomed to procedure-based programming in C, you may find that you need to change how you design your programs when you use Java. Once you see how powerful this new paradigm is, however, you'll quickly adjust to it. In an object-oriented system, a class is a collection of data and methods that operate on that data. Taken together, the data and methods describe the advertisement agency state and behavior of an object. Classes are arranged in a hierarchy, so that a subclass can inherit behavior from its super class. A class hierarchy always has a root class; this is a class with very general behavior. Java comes with an extensive set of classes, arranged in packages that you can use in your programs. For example, Java provides classes that create graphical user interface components (the java.awt package), classes that handle input and output (the java.io package), and classes that support networking functionality
