• With the rise in COVID-19 several physical activities were being disrupted and lockdowns imposed by several state government authorities left artists and auction conducting organizations out of employment.
• Shift to Internet and Online Mode of Auction several challenges like platform security with respect to scalability, user information thefts and maintenance of privacy. User information privacy is also required to prevent manipulation of bids as I see in news several high-profile bids are overpriced as a way of humiliating one organization by another.
• Therefore, the need of this project which is a web application taking in live user data and demonstrates how effectively data gets anonymized and utility maintenance with respect to the need of analyst and testers' requirement download view. While users have the access to perform easy transactions without worrying about their sensitive information and explicit identifiers ever getting leaked.

Cyber Security

Domain: AES, Elliptical Curve Diffie Hellman, Encryption-Decryption, Secure Hash Algorithm

• The approach presented in this project involves the following concepts to ensure that data transferred to the cloud is secure and not intercepted and manipulated by an attacker. AES symmetric cryptography is used to encrypt and decrypt the data that will be sent to the cloud. Elliptic Curve Diffie Hellman (ECDH) is used to exchange the secret key between the user and the cloud. This secret key helps us to encrypt the data when send by the user to the cloud and also while decrypting the data from cloud when the user wants to access the data.
• The purpose of the approach proposed in this paper is to enhance the security of data transfer between the user and the cloud using ECDH algorithm for key exchange along with the improved ECC. For this reason, the approach mentioned in the paper uses ECDH mechanism to exchange the keys between the user and cloud. The challenge is to use in cloud servers with respect to time and memory limitations during encryption and decryption process in servers due to its sharing performance.
• Elliptic Curve Diffie Hellman (ECDH) is used to exchange the secret key between the user and the cloud and AES symmetric cryptography is used to encrypt and decrypt the data that will be sent to the cloud. The ciphertext generated for a particular plain text will always be different which will make it hard for the attacker to be able to decrypt the data which makes this encryption technique unique and hard to decode.

• As we all know that in today’s world of networking, a secure transmission of information with the help of image encryption which can either contain some kind of information or any text information is one of the most important focuses for security.
• In our project I am introducing a (t, n) secret sharing scheme for image encryption. This method encrypts the secret image into two images as the same size of the original image, which one is the public image (called the encrypted image) and another is to be shared among n participants using a new secret sharing method based on the Shamir’s secret sharing.
• In the secret sharing scheme, t (or more) shares secretly held by the participants could reconstruct the shared image, where the size of each share is 2(log m) t 2 / m of that of the shared m*m image. Then the secret image could be recovered from the encrypted image and the shared image through simple XOR operations without any loss.

Technical Answers for Real-World Problems

• The Internet is a complex entity composed of diverse networks, users, and resources. There are some advanced users who use their knowledge to explore potential system vulnerabilities. Hackers can compromise vulnerable hosts by exploiting resources or use them as tools for attacks. The launch of an effective attack often begins with an earlier and deliberate process of analyzing potential victims’ hosts or networks.
• The application model is based on python libraries and exploits the knowledge of networking interfaces of a system. At this moment it was basically a python script which loops over a specified ‘hard-coded’ range and detects if your system has any port open. . After getting the desired output we started implementing multi-threading and reducing the time required for scanning ports to enhance the code. Multi-threading is a concept which makes use of more than one processor to carry out a single task. It simultaneously works on subsequent parts of a process and very efficiently reduces the time.
• It detects the IP addresses that are live and displays it to the user. The next was to enhance IP scanning and move to DNS records. After successful accomplishment of first three objectives development in the UI for this project began. Now, for the functioning of the python script with HTML, a need for a python-based framework arose. Which takes us to next major progress i.e. Connectivity between python script and the rendering of output in UI. This was done using Flask.

• Social distancing is a recommended solution by the World Health Organization (WHO) to minimize the spread of COVID-19 in public places. 2-meter physical distance has been set as the mandatory safety measures in most public places like schools, shopping centers, public transport and other covered areas by the majority of national health authorities and governments.
• Using CCTV footage from security cameras, I developed an automated people detection, tracking and inter-people distance estimation system with the help of Deep Neural Network Based model as part of the research.
• I used the YOLOv3-based framework and also inverse perspective mapping for accurate social distancing monitoring in challenging conditions and people detection, including people occlusion, light variations, and partial visibility. I used the COCO dataset to train my model. From moving trajectories and rate of social distancing violations and statistical analysis of Spatio-temporal data, we have provided an online risk assessment scheme.

• This paper provides an algorithm for the realization of the popular computer games incorporated in a Gaming Console. The basic idea of this work was the development of a gaming console using DOSBox programming environment and libraries used for easier implementation of the game in assembly programming language. Assembler (assembly) language is a low-level programming language, and it is specific to a particular processor (microcontroller) architecture.
• The assembly is used when we need fast and efficient processing of the signal. The MASM library makes programming in assembly easier and provides libraries for work with strings and support for DOSBox features. Some of the main supporting features are graphical environment functions. In this paper, I describe designing a game box using the x86 architecture with MASM libraries in the programming environment DOSBox.
• With this project I understood the working of the first ever interactive games created by the three great classics Brick Break, Snake, and finally the most loved Ping Pong. I also tried to understand the maximum potential in which the 8086 microprocessors could be used and what better way could be the development of games as it exhausts all possibilities for any processors as they are an enigma in itself an epitome of testimony to testify the strength and tenure of any microprocessor.

• As the name suggests “word search” is about searching words in documents parallelly using OPENMP. This is not just a simple word search but it also ranks the documents based on the relevance of the documents with respect to the searched word. The Results are the displayed on a web page which uses PHP (Server-side Scripting language) to render the result. Word search is used everywhere from local page search (Ctrl + F) to searching words on document viewer like “reader” in windows.
• In fact, a whole branch called Information Retrieval was developed for this. This project was actually inspired by Information Retrieval. It has a lot of application in real word. As the name suggests “word search” is about searching words in documents parallel using open. This is not just a simple word search, but it also ranks the documents based on the relevance of the documents with respect to the searched word.
• The Results are the displayed on a web page which uses PHP (Server-side Scripting language) to render the result. The documents are scanned word by word and a dictionary is maintained so that words can be searched. Since documents can have several thousands of terms scanning each term can take a lot of time and hence there is a lot of scope for parallelization.

• Phishing is a type of misrepresentation where the aggressor attempts to learn delicate data, for example, login accreditations or record data by sending as a legitimate substance or individual in email or other correspondence channels. Ordinarily, a casualty gets a message that seems to have been sent by a known contact or association. The message contains malignant programming focusing on the client's PC or has connections to guide casualties to pernicious sites to fool them into disclosing individual and monetary data, like passwords, account IDs or Visa subtleties.
• I used three different methods. (1) URL Classification - Checks assuming that the URLs inside the email are phishing or not. Phishing URL recognition dependent on highlights in URL like length of URL, presence of @ image, prefix and addition isolated by '- ' in area names, presence of IP address, presence of redirection "//". (2) Text Classification-We arrange email text content dependent on word recurrence and in light of semantic investigation. (3) Message ID Classification-Every email is related with a Message ID. The Message-ID resembles an advanced finger impression of a message and is generally added by the mail server that sends your message out in the interest of your mail customer.

• With almost every single chore from ordering to getting delivered is becoming online, the technology has been advancing since every aspect of the life. People can order gadgets, jewelry, moto vehicles, clothes and various other things from online. From past decade, people have the privilege to order to go for a movie based on their desired location and time irrespective of their current location provided if there is an active internet.
• For the user to be able to navigate through these features, they have to create an account by signing in. Every field is validated accurately enough like to check the syntax input type for email-id and for password to be strong that includes an uppercase letter with some special characters and retype password matching with the password entered formerly. Once they have created their account, the user has to remember the login details so that he/she can login insider the user interface of the web application.

• Sending notifications, may be a very hectic and a very tough task to figure out if there is no particular order in which the messages may be sent and no fixed limit on the size and speed of messages, which may become inefficient in urgent needs.
• So, to make sure that the messages sent and received are in a particular order and have a fixed receiver’s address, we make use of Queues. Queues are known to operate on a general FIFO rule. (FIRST INPUT FIRST OUTPUT).
• FIFO (First-In-First-Out) queues are designed to enhance messaging between applications when the order of operations and events is critical, or where duplicates can't be tolerated. The order in which messages are sent and received is strictly preserved and a message is delivered once and remains available until a consumer processes and deletes it.
• The details of the messages will come to the user itself and will also be saved on our server. We also have made sure that the message sent are also stored in a backup file, on our server, where if anything happens to our current queue messages, we don’t lose the information stored in the message. Messages that belong to the same message person are always processed one by one, in a strict order relative to the message group.

• We present to you Club Connect, the perfect club management app that solves all the hassles of organizing a club. We have designed and created an android device application that will help all clubs to organize better. We have addressed all the problems that arise within a club when it comes to news and updates. In our app, we have made a login page for all the members. Now as we know, members of the club are recruited by senior club members.
• Therefore, we only have a login page. The members of the club will be given usernames and dummy passwords by admins (senior members) and only those people will be allowed to use the application. This adds a level of security and authentication to the application.
• The application has a common interface for different types of technical and non-technical clubs. Board Members of the club can update the database as currently the application does not have an admin portal. The members of a club will get a unique id to login and access the application. Club members can view all the ongoing activities, upcoming events as well as the schedule of their meetings and duties. They can give their profile and can also post their availability or unavailability for a meeting or duty.

• With the increasing number of cars and traffic, it has become a major problem to find place for parking cars in public places such as market places or malls or any famous place. This results in severe congestion. There are cases where parking slots are available but they are either isolated, or too far from the entry point or not known to drivers.
• I am going to use Semaphore and FCFS Synchronization as a non-pre-emptive scheduling algorithm. Basically, I am going to use two Semaphores and a switch for the entire process of automatic parking. A semaphore, in its most basic form, is a protected integer variable that can facilitate and restrict access to shared resources in a multi- processing environment.
• While the deadlock avoidance procedure takes place through semaphores all the waiting vehicles in the queue needs a scheduling order. Since pre-emptive methods are not suitable in parking systems as I cannot again disturb a car’s position. So I am going to use non preemptive First Come First Serve Scheduling Algorithm. I am aiming to use Process Synchronization and their scheduling the most important concepts of Operating Systems to solve the problems of parking management.

• The government and a large number of private companies have built a number of sporting facilities to encourage the playing of sports. However, not everyone can always easily use these services. At times, even when they are, they are typically quite packed. Additionally, these facilities are typically in poor shape since the proprietors lack any motivation to handle them well because they are not very profitable. The causes are lack of visibility and spotlight marketing having a coordinated effect and no one to address these issues. There's a void between those who have an interest in sports and those who are administering the sporting venues, a gap that we want to fill with our idea.
• This issue can be effectively solved by our Android mobile application, which we developed. The programme is called Grook. With the help of the sports management software Grook, users can reserve local sports fields, courts, and other facilities for certain times, ensuring that they always have a place to play. It enables facility managers to run their businesses more effectively and also compiles all of the sporting venues close to the user's location.
• Creating teams with other users who share your interest in certain sports is another feature of our app. Users must pay a nominal charge to the sports facility administration to reserve a time slot for them, depending on the sports facility and the sport they desire to play. We now have our database, which contains the date, day, month, year, the name of the sports facility, the total cost, and the total number of clients, utilising the data from all of these entries. The amount of consumers that make reservations at a facility and the various sports for which the reservations are made determine the facility's overall income on any given day.

• Have you heard of the Pomodoro technique? The Pomodoro technique is a time management method that increases your productivity and efficiency. Our entire group believes in the Pomodoro way of working which dictates that you have to work for 25-minutes and then take a 5-minute break. When we found out that there is no application out there to fulfill all of our requirements in one place, we saw an opportunity. Selfuel – The Pomodoro Way, a perfect app to cater to all your work needs.
• Our application implements this technique very beautifully. The user is supposed to enter all the tasks and the approximate minutes (multiples of 25) the user will take to complete the task. Selfuel will create a ToDo List of all the tasks. ToDo List is a simple tool to keep a record of the tasks the user needs to complete. Along with adding new tasks the user has the option to delete and edit the already added tasks. As soon as the user clicks on the task to begin it. The clock will start and will work according to Pomodoro minutes i.e. Once the clock starts, the user is supposed to work straight for 25 minutes. After 25 minutes the clock will start the break time of 5 minutes and suppose if the user has set the time to 50 minutes the clock will again start for the next 25 minutes.
• For developing interest and attracting users application has a feature to add their friends and see their score on the leaderboard. This competitive behavior will motivate and compel the users to stay focused and complete the task in duration. Studying and working go faster and are more enjoyable when you have a soundtrack. The application allows to user to upload his favorite playlist which can be played while completing the task.
