Abstract- Steganography is the art of hiding information in ways that avert the revealing of hiding messages.Video files are generally a collection of images. so most of the presented techniques on images and audio can be applied to video files too. The great advantages of video are the large amount of data that can be hidden inside and the fact that it is a moving stream of image. In this paper, we proposed a new technique using the motion vector, to hide the data in the moving objects. Moreover, to enhance the security of the data, the data is encrypted by using the AES algorithm and then hided. The data is hided in the horizontal and the vertical components of the moving objects. The PSNR value is calculated so that the quality of the video after the data hiding is evaluated.
Keywords- Data hiding, Video Steganography,PSNR,
Moving objects, AES Algorithm.

I. INTRODUCTION
Since the rise of the Internet one of the most important factors of information technology and communication has been the security of information.
Steganography is a technology that hides a user defined information within an object, a text, or a picture or in a video files. Steganography is Greek word has the meaning of , “Stegano”, or “covered” and “graphy” or “writing” which does not convey the transformation of information, but rather its hidden aspect.
In
steganography, the object of communication is the hidden message and the cover data are only the means of sending it. Secret information as well as cover data…...

...Tobi Gonzalez 2/25/13 Motion is Relative 1. The two units of measurement are distance and time. 2. The kind of speed is registered by an automobile speedometer is instantaneous speed. 3. Average speed is the speed averaged over duration of time. Usually the total distance covered divided by the total time. Instantaneous speed is the speed given at that instant within that span of time, measured with a real time speedometer. 4. The average speed in kilometers per hour for a horse that 
gallops a distance of 15 km in a time of 30 min is: Average speed = 15 km/30 min = 15 km/0.5 h = 30 km/h 5. Speed is the distance covered per unit of time. Acceleration is the rate in which an object changes its velocity. 6. If a car is moving at 90 km/h and it rounds a corner, also at 90 km/h, 
it does maintain a constant speed but not a constant velocity. The velocity never changed, only the direction it’s traveling. 7. Velocity is change in displacement, change in position over a period of time, while Acceleration is change in velocity over a time period. 8. The acceleration of a car that increases its velocity from 0, to 
100 km/h in 10s is 10km/h*s 9. The acceleration of a car that maintains a constant velocity of 
100 km/h for 10s is 0 km/h*s. Some of my classmates get this question wrong but the last question right because they fail to read the question. In the last question there was a change in velocity. However in this question there was no change in...

... #2 The Study of Concurrent Forces with the Force Table Apparatus: Force table with 4 pulleys, centering ring and string, 50 g weight hangers, slotted weights, protractors, and rulers. Discussion: The force table is designed to help you study the properties of forces at known angles. Only when forces are along the same line do they add by ordinary algebra. If two or more forces on the same body form angles with each other, it is necessary to use geometry to find the amount and direction of their combined effect. Prior to Lab: Complete the calculations in the following. The component method of adding vectors is given here for three sample forces as follows: A = 2.45 N @ 40o B = 3.92 N @ 165o C = 3.43 N @ 330o Overview of the component method of vector addition. First make a neat drawing, not necessarily to exact scale, but reasonably accurate as to sizes and angles, placing the three forces on a diagram with a pair of x and y axes. Find the angle of each force with the x-axis. This angle is called the reference angle, and is the one used to calculate sines and cosines. Next compute the x- and y-components of the three forces, placing like components in columns. Place plus or minus signs on the various quantities according to whether an x-component is to the right or left of the origin, or whether a y-component is up or down relative to the origin. Add the columns with regard to sign (subtracting the minus quantities), and place the correct sign on each sum. The resulting...

...Motions: * Politics This House would grant politicians immunity from prosecution PROS Giving politicians’ immunity from prosecution allows them to focus on performing their duties The premier reason that most states, even those that allow for the prosecution of politicians, abstain from prosecuting them while they hold office is that being a politician is a job that requires one’s undivided attention.  Especially for the holders of prominent national-level offices, writing legislation, responding to crises under one’s purview, consulting one’s constituents, and engaging in campaign work often lead to politicians working an upwards of 12 hour day, every day.  To expect politicians cope with all of these concerns will simultaneously constructing a defense against pending charges would be to abandon all hope of them serving their constituents effectively.  We are rightly aggravated when politicians take extensive vacations or other extracurricular forays. Being under indictment not only consumes even more of a politician’s time; the stress it causes will inevitably seep into what remaining time they do allocating to fulfilling their duties, further hindering their performance.  The impeachment proceedings for Bill Clinton on charges of perjury and obstruction of justice were so intensive that they took tremendous resources away from not only the president himself, but all branches of the federal government for several months, amidst serious domestic and foreign...

...VECTOR FUNCTIONS VECTOR FUNCTIONS Motion in Space: Velocity and Acceleration In this section, we will learn about: The motion of an object using tangent and normal vectors. MOTION IN SPACE: VELOCITY AND ACCELERATION Here, we show how the ideas of tangent and normal vectors and curvature can be used in physics to study:  The motion of an object, including its velocity and acceleration, along a space curve. VELOCITY AND ACCELERATION In particular, we follow in the footsteps of Newton by using these methods to derive Kepler’s First Law of planetary motion. VELOCITY Suppose a particle moves through space so that its position vector at time t is r(t). VELOCITY Vector 1 Notice from the figure that, for small values of h, the vector r(t h) r(t ) h approximates the direction of the particle moving along the curve r(t). VELOCITY Its magnitude measures the size of the displacement vector per unit time. VELOCITY The vector 1 gives the average velocity over a time interval of length h. VELOCITY VECTOR Equation 2 Its limit is the velocity vector v(t) at time t : r(t h) r(t ) v(t ) lim h 0 h r '(t ) VELOCITY VECTOR Thus, the velocity vector is also the tangent vector and points in the direction of the tangent line. SPEED The speed of the particle at time t is the magnitude of the velocity vector, that is, |v(t)|. SPEED This is appropriate because, from Equation......

...Find parametric equations for the line L which contains A(1, 2, 3) and B(4, 6, 5). Solution: To get the parametric equations of L you need a point through which the line passes and a vector parallel to the line. −→ Take the point to be A and the vector to be the AB. The vector equation of L is −→ −→ r(t) = OA + t AB = 1, 2, 3 + t 3, 4, 2 = 1 + 3t, 2 + 4t, 3 + 2t , where O is the origin. The parametric equations are: x = 1 + 3t y = 2 + 4t, z = 3 + 2t t ∈ R. Problem 1(b) - Fall 2008 Find parametric equations for the line L of intersection of the planes x − 2y + z = 10 and 2x + y − z = 0. Solution: The vector part v of the line L of intersection is orthogonal to the normal vectors 1, −2, 1 and 2, 1, −1 . Hence v can be taken to be: i j k v = 1, −2, 1 × 2, 1, −1 = 1 −2 1 = 1i + 3j + 5k. 2 1 −1 Choose P ∈ L so the z-coordinate of P is zero. Setting z = 0, we obtain: x − 2y = 10 2x + y = 0. Solving, we find that x = 2 and y = −4. Hence, P = 2, −4, 0 lies on the line L. The parametric equations are: x =2+t y = −4 + 3t z = 0 + 5t = 5t. Problem 2(a) - Fall 2008 Find an equation of the plane which contains the points P(−1, 0, 1), Q(1, −2, 1) and R(2, 0, −1). Solution: Method 1 −→ −→ Consider the vectors PQ = 2, −2, 0 and PR = 3, 0, −2 which lie parallel to the plane. Then consider the normal vector: i j k −→ −→ n = PQ × PR = 2 −2 0 3 0 −2 = 4i + 4j + 6k.

Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. When you drag the red ball in a direction two arrows appear. One of the arrows is green and one of the arrows is blue. In the same direction that u drag the ball, the green and blue arrow point the same direction. After a second or two, the blue arrow changes to a complete opposite direction but the green arrow does not change. If I drag the red ball faster the arrows get longer and slower I drag the red ball the smaller the arrows. 2) Which color vector (arrow) represents velocity and which one represents acceleration? How can you tell? The green arrow goes in the same direction that you drag the red ball and would therefore represent velocity. The blue arrow, at first, goes in the same direction that you drag the red ball. Then as the ball slows down the blue arrow changes and goes in the opposite direction, this would make the blue arrow acceleration. 3) Try dragging the ball around and around in a circular path.
