Today Information Technology has become a part of our everyday life. Information Technology means use of computers and internet to store, retrieve, transmit and manipulate the information. So all the organizations, industries and also every individual are using computers to store and share/communicate the information. So here security is very much important while storing and communicating the information. For this security various techniques are available. Among them the most common and easy to use is a password. It can be considered as a principal part of authentication process. The traditional password technique is textual password. But there are various deficiencies in this password. It is vulnerable to various attacks. So to overcome these limitations alternative technique is introduced which is Graphical Password. As name indicates, in this, various images/pictures are used as a password. But it is observed that because of graphic nature nearly all the graphical passwords are vulnerable to shoulder surfing attack. To overcome this here a new graphical password authentication technique is developed which is a combination of Recognition and Recall approach based techniques. It is more usable and secure as compare to previous graphical password authentication systems. As password space is very large it provides the security against brute force attack. It is easy to use. Passwords can be created and memorized easily. Randomization in both the authentication steps provides strong security against shoulder surfing. Overall the system is resistant to all other possible attacks also. This system is used for highly secure systems. It can be also useful for smart phones, PDA, iPod, iPhone etc.

Working of the System:

It has two phases:1. Registration Phase2. Login Phase

Registration Phase:

1. The user enters the username.

2. Then 25 images are shown to the user. The user has to select some number of images toset as a password. This password is called as a secret pass. The minimum number of images in the secret pass should be 6. Also the secret pass should contain even number of images to form the pairs of images. A session password is generated based on this secret

pass. This is a password for user's step-I authentication. The images selected by the user are displayed in the panel, below the grid of images in a sequential manner so that selected images can be easily seen and remembered by the user in a sequence and can confirm the image selections according to his choice. It will disappear after 5 seconds for security. This makes the system secure as well as user friendly. It is shown in Fig.1.

Fig. 1 Step-1 Registration

3. After this user will select any picture from the image database or from the local memory.

4. Then the user is presented with this picture and a question set. The user has to select any three questions from this set.

5. As an answer of questions user has to click on any point on the image. So for three questions there will be three different points. Individual point is called as ROA. So there are three different ROAs (Region of Answers) for three different questions. These three different ROAs is the step-II password. It is shown in Fig.2.

6. Also the email-id, mobile number, one secret question from the question set and its related secret answer should be registered by the user during registration. These are also shown in Fig.2. These additional features will be used when user forgets the password; that password will be mailed to user's registered mail–idand user has to prove his authenticity by answering the secret question correctly. Also the OTP (One Time Password) will be sent to this registered email-id if the system is blockedbecause of any reason. System will be unblocked only after entering this OTP correctly.

Login Phase:

1. For step-I login, which is based on recognition based approach, user is asked for username. After entering the correct username the user has to enter the graphical password. For this, user is presented with a grid of 25 images, randomly placed on the grid. The image positions will change at every login. The user has to enter the session password depending upon this secret pass. The user has to form the pairs of images in this secret pass. The first image is used to select the row and the second image is used to select the column. The intersection image is a part of the session password. For example, during registration, in secret pass suppose first image is bag and second image is fanso during login, first intersection image in session password is shoe. This is shown in Fig.3. In this way it is repeated for all pairs of secret pass. The intersection images in the session password will vary at every login. This makes our system strongly secure. Thus it is very difficult for any imposter to guess or crack this step-I password.

Fig. 3. Step I Login

2. Only after successful identifications in Step-I, the user can go for Step-II login which is based on recall based approach. The preselected image and only preselected question numbers instead of whole questions are shown to the user. Both are clues to recall password.

3. Here the order of question numbers will be random. All the three question numbers are shown as a single three digit number in a text box i.e. 471 as shown in Fig.4. This is a modification in our system for more security. The user has to

select the correct ROAs (center and some tolerance in both X and Y axis) according to the order of question numbers. Here only three question numbers are shown to the user as a single three digit number and also its order randomizes at every login. So it is very difficult for attacker to remember step-II password easily.

Fig. 4. Step II Login

4. After successful selections in step-II, user is an authorized user to access the system. Thus, step-I and step-II passwords are difficult to guess or crack for attacker, but easy to remember for user. So our system is strongly secure as well as user friendly.

Advantages:• As this system is a good combination of two types of

graphical passwords techniques, it has a large password space and provides a strong security against brute force and guessing attacks.

• Randomization in both the authentication steps provides strong security against shoulder surfing attack.

• Overall our system is resistant to all other possible attacks also. This system can be used for highly secure systems.

Introduction

Model Predictive Control is an advanced method of process control that has been in use in the process industries such as chemical plants and oil refineries since the 1980. The models used in model predictive control are generally intended to represent the behavior of complex dynamical systems. Model predictive control (MPC) is becoming the standard technique to solve multivariable control problems in the process industry. Practically all MPC systems are however operating in a supervisory mode with PID controllers at the lower level. A substantial portion of the performance improvement credited to MPC is actually due to improvements in the lower-level PID loops.

MPC Strategy

Model predictive control refers to family of control algorithms that employ an explicit model to predict the future behavior of the process over a extended prediction horizon. These algorithms are formulated as a performance objective function which is defined as a combination of set point tracking performance and control effort. This objective function minimized by computing a profile of controller output moves over a control horizon. The first controller output move is implemented, and then the entire procedure is repeated at the next sampling instance. Figure 1 shows the moving horizon technique used in MPC.

Fig. 1. MPC Strategy

Fig. 1 shows values of set points, measured disturbances, and

constraints are specified over a finite horizon of future sampling instants, k + 1,k + 2....k + P, where P is finite integer≥1 is the prediction horizon . In fig. 2 MPC then calculates the M moves uk,uk+1,....,uk+m−1,where M(≥1≤P) is the control horizon. These moves are optimal in the sense that no constraints are violated and the output track the set point closely. MPC sends only the move uk to the plant. The plant operates with this input until MPC's next sampling instant, ∆t time unit later. MPC then obtains a new set of measurements and revises completely the plan it had formulated at the previous sampling instant, thus compensating for model error and unknown disturbances.

Basic structure of MPC

In order to implement above strategy, the basic structure shown in figure.

Elements of MPC1. Model2. Optimizer3. Objective Function4. Constraints

1. Model

A model is used to predict the future plant outputs, based on past and current values and on the proposed optimal future control actions. These actions are calculated by the optimizer taking into account the cost function (where future tracking error is considered) as well as the constraints. The process model plays, in consequence, a decisive role in the controller.

The chosen model must be capable of capturing the process dynamic, so as to precisely predict the future outputs as well as being simple to implement and understand. As MPC is not a unique technique but a set of different methodologies. There are many types of models used in various formulations. One of the most popular in industry is the truncated impulse response model, which is very simple to obtain as it only needs the measurement of the output when the process is excited with an impulse input. It's main drawbacks are the large number of parameters needed and that only open loop stable processes can be described this way. The transfer function model is most widespread in the academic community and is used in most control design methods, as it is a representation that requires only a few parameters and is valid for all kind of processes.The state space model is also used in some formulations, as it can be easily describe multivariable processes. The state space description allows for an easier expression of stability and robustness criteria.

2. Optimizer

It provides the control actions. If the cost function is quadratic, it's minimum can be obtained as an explicit functions(linear)of the past inputs and outputs and the future reference trajectory. The size of the optimization problem depends upon the number of variables and the prediction horizon used. The amount of time needed for the unconstrained case and the bandwidth of the process to which constrained MPC can be applied is considerably reduced.

3. Objective function

The general aim of the cost function is that the future output(y) on the considered horizon should follow a determined reference signal (r) and at the same time the control effort ∆y necessary for doing so should be penalized.

4. Constraints

In practice all processes are subject to constraints. The actuators have a limited field of action and determined slew rate, as in the case of valves. Constructive reasons, safety or environmental ones can cause limits in process variable such as level in tanks, flow in pipes or maximum temperature and pressure. Constraints at operational conditions are normally defined by the intersection of economic reasons, so that control system will operate close to the boundaries. Normally bounce in the amplitude and in the slew rate of the control signal and limits in output will be considered.

Advantages of MPC

MPC is the established advanced control technique for the

process industry. It is already an indispensable tool and its importance is continuing to grow. Some of the advantages of MPC are listed below.

• A generic approach that can be applied to a wide range of processes.

• MPC can be used to handle single and multivariable control programs.

• Straightforward formulation, based on well understood concepts, can perform online computations quickly.

• Explicitly handles constraints, structural changes.• Explicit use of a model• Well understood tuning parameters -Prediction horizon -

Optimization problem setup• Development time much shorter than for competing

advanced control methods.• Easier to maintain: changing model or specifications does

not require complete redesign.

When a fresh engineering graduate with twinkling and dreaming eyes comes out with his/her degree certificate and tries his luck for the job, he/she realizes the harsh reality of the corporate world.

A bachelor's degree in engineering requires 4-5 years to complete. The course starts out with general education requirements and general engineering courses, and students specialize in a specific area during the latter two years. After completion of the course, 80-90% of the students try to settle down in their life with a good job. But the reality is many of them are rejected due to their lack of practical experience, and skills like communication, problem solving capacity and motivation to succeed even though they have strong academic background. The reason is in front of us! The technology is becoming obsolete within no time and needs to keep in touch with the recent developments. By the time the students pass out with their degree in hand with prescribed syllabus or curriculum, there will be a large gap between student's academic knowledge and industry's expectations. This situation leaves the students struggle for their employment.

In India, engineering colleges are increasing in many folds every year. About 1.5 million students pass out every year. It is said that there is no dearth for engineers, but there is a dearth for skilled engineers due to which, as per the survey [ ], the percentage of employment of Aspiring Mindsengineers is merely 18% to 20%. The corporate sector prefers engineers who have practical knowledge along with sound theoretical knowledge. But how to get experience without job? The solution can be: 1. The curriculum should be revised and designed periodically in consultation with corporate world.2. The time table should focus on practical in comparison with theory classes.3.The authority responsible should try to have tie up between educational institutes and concerned corporate sectors so that students can be given hands on experience in their specialized field.4. The students should be motivated and guided to undergo internship during their vacations to upgrade themselves with the existing technology of their specialization.

Because of quick advancements in the technology, engineers have to stay in the forefront in their knowledge. Otherwise, unemployment ratio increases which can cripple our country's economy which is a direct reflection of India' growth.
