Rutger University offers classes which visitors to the university can attend only if they are registered for the classes. Registration for the classes requires paying a nominal fee to the bursar, and you need account. The verification of visitors' registration is required in order for a visitor to attend a class, and this verification is done by a system administrator who is also required to log into the system. The verification is done through logging into the Rutgers registration system. If a visitor tries to log in to the system without being registered, an error message will be displayed by the system. Only a System Administrator will be able to create an account for a user of the system. The system administrator is also responsible for resetting login credentials (username and password) To get credit for the course, a participant must take a final exam which is set by a professor and uploaded to the system. The final exam when submitted by the student is reviewed by the professor…
What Punishment for Webcam Spying is Appropriate? Microphones, digital cameras, and webcams have many practical and harmless uses. These technologies also can leave you open to spying. For example, one school district used software, which was supposed to track the school-distributed laptops in case of theft, to take photos and scree captures of students. In another instance, a person noticed that when she gave a customer service rep access to her computer, he turned on her webcam without asking for her permission. Cybercriminals can use spy tools take photos, or record video or audio, without turning on a light or other notification that indicates your camera or microphone is in use. The Flame virus is one way for spy tools to infect your computer. Security experts recommend using a sticker to cover your webcam and inserting a dummy plug in the microphone port when you are not using it. These technologies also allow people to take photos or videos in a public setting and share them…
A SAF authorization form is used in most universities to approve funding for students to aid their studies. Suppose a student fills out a blank form and sends it to his or her departmental chairperson for a signature. If the amount of funds requested by the student is small (under 10,000 Tk), then the chairperson signs the form and routes it to accounts payable to be input into the accounting system. The system cuts a check that is sent to the student for the right amount, and after the check is cashed, the form is filed away with the canceled check. If the check is not cashed within 30 days, the form expires. When the amount of the requested fund is large (over 10,000 Tk), the chairperson signs the form and sends it to the chief financial officer along with a paragraph explaining the reason for the grant, and the chief financial officer will sign the form and pass it along to accounts payable. Both the chairperson and the chief financial officer can reject the SAF authorization form…
A phishing attack on a certain social media platform locks users out of their accountsand spreads by sending malicious links to their followers to gain access to more accounts. On thefirst day, the attack has hacked into 2 accounts. Near the beginning of each of the following days,each hacked account sends links to 4 new accounts, which subsequently become hacked as well.By the end of the second day, IT support has found a way to restore users’ accounts, and 1 accounthas been restored at that point. Each day thereafter, 5 times as many accounts have been restoredas the previous day. (a) Write a recurrence relation for the total number of hacked accounts at the end of day n.(b) Solve the recurrence relation.(c) How many days will it be until all users’ accounts have been completely restored?
Bob has designed a secure login system for the student portal of the Xiamen University of Technology (XUT). In Bob's design, a two-factor authentication method is used for verifying the authenticity of the user. A brief description of the design is provided below. For the two-factor authentication, the followings are required: • Factor 1: a user first required to provide a secret password, • Factor 2: the user then needs to provide the correct answer to a security question. To securely store the user password in the system, Bob has used state-of-the-art encryption algorithm, Advanced Encryption Standard (AES), to encrypt the user password and stored the encrypted password in the system database. For securely signing in to the system: the user needs to provide his/her user ID and the corresponding password. This information will be transmitted to the system over a secure communication channel. Upon receiving this information, the system will: o locate/retrieve the corresponding…

CMO: Why do we need to save the transcripts at all, then? You: Chatbot programs are Al-driven, and most of them continue to learn from each conversation, even once the chatbot is released into the production environment. Transcripts of conversations help the chatbot get smarter and handle future conversations more skillfully. We do need to be careful what a chatbot learns in a live environment, though. Chatbots should never be allowed to do or say anything that could be harmful to a human. For example, we'll need to configure Select to keep the chatbot's vocabulary under control.

A security system implementation company is contacted by DLD lab, for the implementation of authentication system so that BEE-2 students can get lab access. The system will utilize RFID based university card scanner, password entry and verification mechanism and a fingerprint scanner. The system should work as follows: the student should get its RFID card scanned by the system. If scanning is done successful (valid) then the system will ask you to provide password. Along successful scanning and a valid password, the access is granted. If in any case the above verification is avoided, then the student is required to pass through fingerprint scanning. Only on matched fingerprint, the student is granted access. LA=F (FP, PW, RFID) Where FP: fingerprint PW: password entry RFID: RFID scanner LA: lab access a) Compute the truth table for the system b) Using part(a) write the system Boolean function c) Simplify the system to minimum number of gates using K-map d) Design the system obtained in…
blockchain is a collection ofrecords (called blocks), where each block links to the previous block using cryptography. Eachblock contains cryptographic hash, timestamp and data relevant to its application. Think ofit as a distributed ledger where instead of information being stored in a database it is storedon the blockchain. Some examples of solutions that use a blockchain at its core are:1. Cryptocurrencies (however, for this project you may NOT do a cryptocurrency)2. Smart contracts3. Trading4. Supply chain management5. Anti-counterfeiting6. Healthcare7. Domain names8. Proof of existence9. Voting10. and many others!
