Some highly confidential documents need to be kept in a super secured vault. The vault has 5 steps of security checkpoints without any human security personnel. Only an authorized person gets 5 different passwords to open and close 5 different security gates. Each password is effective to open and close the very same gate once. You have to enter 5 different authorized passwords to open 5 different gates. You have to keep track of which password was used to open one gate so that you can close the gate with the same password after finishing your job in the vault. You will finish your job in the vault and lock the series of gates using the correct sequence (which one you used to enter) of passwords. The passwords will be of string type. Question 1: Which data structure would you choose to keep track of the sequence of passwords to access the vault? Answer: Question 2: Write the Pseudocode of the insertion operation of this data structure. Answer: Question 3: Write the Pseudocode of the deletion operation of this data structure. Answer:

Concoct a made-up story as a means of illustrating the steps involved in the sign-in process. There is a good chance that you have already been subjected to a variety of authentication procedures. When can we expect it? In my opinion, there is no way that passwords will ever be rendered unnecessary.
Can we accomplish anything with the help of authentication?As you can see, there are a number of factors to consider when choosing an authentication method.
Create a fictitious scenario to demonstrate how the login procedure works. It is probable that you have experienced a number of authentication techniques. Any time soon? I do not believe that passwords will ever become obsolete.

I have a casual curiosity in the Master of Fine Arts program, therefore I'd want to learn more about it. Concerns concerning a password's usefulness are raised by the fact that its contents can be seen by no one save the person to whom it is addressed.
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…
