A and b verify that they possess a common key k, using a public one-wayfunction h, as follows:1. a sends h(h(k)) to b2. b verifies that the received value is correct3. b sends h(k) to a4. a verifies that the received value is correct

Answers

Answer 1

In this scenario, A and B are using a public one-way function (h) to verify that they possess a common key (k). The process starts with A sending h(h(k)) to B, which B verifies is correct. B then sends h(k) to A, which A verifies is correct.

To clarify, A and B verify that they possess a common key (k) using a public one-way function (h) through the following steps:

1. A sends h(h(k)) to B: A applies the one-way function h twice on the common key k and sends the result to B.

2. B verifies that the received value is correct: B also applies the one-way function h twice on their key k and checks if the result matches the value received from A.

3. B sends h(k) to A: After verification, B applies the one-way function h once on the common key k and sends the result to A.

4. A verifies that the received value is correct: A applies the one-way function h once on their key k and checks if the result matches the value received from B.

This process helps A and B confirm that they both have the same common key k while using the public one-way function h to ensure the security of their communication.

The Assignment

For the purpose of this assignment, we will be asking you to do a simplified version of the algorithm using 2D Cartesian points and Euclidean distance measurement to calculate closeness. The Rules

Each point given will have a unique (x,y) coordinate. Each point will be classified as either R for Red or B for Blue. There will never be a tie as to what an object will be classified as. Input

As input you will be given on the first line n and k followed by 1 <= n <= 100 lines each containing a pre-classified point. N is the number of pre-classified points given, 1 <= k <= n is the number of nearest neighbors you will use to classify your unknown point. Each of the pre-classified points will be represented on separate lines in the form x y c where x and y are the Cartesian coordinates of the point -100. 0 <= x,y <= 100. 0 and c is its label, either R or B. Finally on the last line you will receive, in the format x y, the Cartesian coordinates of the point which should be classified. For example:

Write a java method that receives three strings and returns a string containing
distinct common characters among the three strings ignoring case for letters.
write a program to test this method.​

Answers

The Java method we created takes in three strings and returns a string containing the distinct common characters among the three strings, ignoring case sensitivity. We tested the method in a program by calling it with different sets of strings.

To write a Java method that takes in three strings and returns a string containing the distinct common characters among the three strings, ignoring case sensitivity.

First, we can create a HashSet to store the characters that are common in all three strings. We can convert all the strings to lowercase to ignore case sensitivity. Then, we can iterate through each character of the first string and check if it is present in the second and third strings. If it is, we add it to the HashSet. Finally, we can convert the HashSet to a string and return it.

Here is the code for the method:

java
public static String commonChars(String str1, String str2, String str3) {
   HashSet set = new HashSet<>();
   str1 = str1.toLowerCase();
   str2 = str2.toLowerCase();
   str3 = str3.toLowerCase();
   
   for (char c : str1.toCharArray()) {
       if (str2.indexOf(c) != -1 && str3.indexOf(c) != -1) {
           set.add(c);
       }
   }
   
   StringBuilder sb = new StringBuilder();
   for (char c : set) {
       sb.append(c);
   }
   
   return sb.toString();
}

To test this method, we can create a main method and call the commonChars method with different sets of strings. Here is an example:

java
public static void main(String[] args) {
   String str1 = "hello";
   String str2 = "world";
   String str3 = "help";
   
   String common = commonChars(str1, str2, str3);
   System.out.println(common);
   // Output: helo
}


In conclusion, the Java method we created takes in three strings and returns a string containing the distinct common characters among the three strings, ignoring case sensitivity. We tested the method in a program by calling it with different sets of strings.

Maintain a Database Security (Inference Detection Algorithm)


Consider a database containing personnel information, including names, addresses, and salaries of employees. Individually, the name, address, and salary information is available to a subordinate role, such as Clerk, but the association of names and salaries is restricted to a superior role, such as Administrator.


1. With this information, how could you construct your database and tables? Design your database and draw a database schema first.


2. Suppose that administrators wants to add a new attribute, employee start date, which is not sensitive. Where would it be? Consider not comprimising the relationship between employee and salary. Draw your new schema

Answers

To construct a database for personnel information, we can create three tables: "Employees," "Addresses," and "Salaries."

The employee start date can be added to the "Employees" table as a new column, as it is not sensitive information.

Explanation:

To design a database for personnel information, we can create three tables: "Employees," "Addresses," and "Salaries." The "Employees" table contains the name and employee ID of each employee. The "Addresses" table contains the employee ID and their corresponding address. The "Salaries" table contains the employee ID and their corresponding salary. The "Employees" table is accessible by both Clerks and Administrators, while the "Addresses" and "Salaries" tables are accessible only by Clerks and Administrators, respectively. The database schema for this design would consist of three tables with the employee ID serving as the primary key and foreign keys linking the tables.

The employee start date can be added to the "Employees" table as a new column, as it is not sensitive information. This column would not compromise the relationship between employee and salary, as the salary information is still only accessible by Administrators through the "Salaries" table. The new database schema would include the "Employees" table with the added column for employee start date.

which of the following statements about reducing storage space in inverted indexes is true? a. delta encoding reduces storage space when document numbers are close together. b. stop word removal is sometimes used to reduce run-time storage requirements. c. v-byte encoding is used to store numbers in as many bytes as possible. d. a

Answers

The correct statement about reducing storage space in inverted indexes is option A, delta encoding reduces storage space when document numbers are close together. Delta encoding is a technique that involves storing the difference between adjacent values instead of storing each value separately.

1)Delta encoding works best when the document numbers are close together because the differences between them are smaller. When the differences are large, the encoding may require more space than storing the numbers directly.

2)Stop word removal, as mentioned in option B, is a technique used to improve search performance by removing commonly used words that do not add value to the search results. This technique does not directly affect the storage space requirements of inverted indexes.

3)V-byte encoding, as mentioned in option C, is a variable-length encoding scheme that stores numbers in as few bytes as possible. This technique is commonly used in compression algorithms but is not specific to inverted indexes.

4)In summary, delta encoding is an effective technique for reducing storage space in inverted indexes when document numbers are close together.

Write a short essay (roughly 500 words) about some topic related to computing

technology or the Internet that interests you and has social or ethical implications. Describe the background; then identify the issues, problems, or questions that you think are important.

Answers

The rise of artificial intelligence (AI) raises important social and ethical concerns including potential job loss, bias in algorithms, military applications, privacy, accountability, and impact on society.

How does AI raise social and ethical concerns?

One of the most significant developments in computing technology in recent years is the rise of artificial intelligence (AI).

AI has the potential to revolutionize many fields, from healthcare to transportation, One of the most pressing issues facing the computing technology industry today is the growing problem of electronic waste, or e-waste.

E-waste refers to any electronic device that is no longer useful or functional and is discarded, often ending up in landfills or being exported to developing countries.

This issue has significant social and ethical implications, as well as environmental consequences.

Background:

As technology continues to advance, the average lifespan of electronic devices decreases, resulting in an increasing amount of e-waste. According to a report by the United Nations, the world generated 53.6 million metric tones of e-waste in 2019 alone. This is equivalent to throwing away more than 4,500 Eiffel Towers every year. E-waste contains a range of hazardous materials, including lead, mercury, and cadmium, which can pollute the environment and pose health risks to humans.

Issues:

The first issue with e-waste is the environmental impact. When electronic devices are not disposed of properly, they often end up in landfills or are incinerated, releasing harmful chemicals and toxins into the air, water, and soil. This pollution can have serious consequences for both human health and the environment, including an increased risk of cancer, respiratory problems, and other health issues.The second issue is the social and ethical implications of e-waste. When e-waste is exported to developing countries, it can contribute to unsafe and exploitative working conditions for those who handle the waste. Workers in these countries may be exposed to hazardous chemicals and toxins while disassembling and processing electronic devices, leading to health problems and even death.Another ethical issue with e-waste is the problem of planned obsolescence. This refers to the practice of designing products with a limited lifespan, often forcing consumers to replace them sooner than necessary.Companies may do this intentionally to boost sales, which can contribute to the growing e-waste problem.

Solutions:

One solution to the e-waste problem is the development of more sustainable and eco-friendly products. This would involve designing devices that are more durable and repairable, with components that can be easily replaced or upgraded. Companies could also use more sustainable materials in their products, reducing the need for mining and reducing environmental impact.Another solution is to promote responsible disposal and recycling of electronic devices. This could involve implementing e-waste collection programs in communities, where individuals can drop off their devices for proper disposal or recycling. Companies could also be required to take back and recycle their products at the end of their useful life.Education and awareness campaigns are also crucial in addressing the e-waste problem. Consumers need to be educated on the importance of responsible disposal and recycling, as well as the impact of their purchasing decisions on the environment and society. This could include providing more information on product lifespans, recycling options, and the environmental impact of electronic devices.

Conclusion:

In conclusion, e-waste is a significant issue facing the computing technology industry, with serious social, ethical, and environmental implications.

Collaborative effort needed from consumers, companies, and governmentsFocus on sustainable practices to reduce e-waste and ensure a more sustainable future.

b. Show how to decide the answer to the agency’s question with only O(nlog n) requests to the social networking company

Answers

a. The government agency's question is whether there is a set of more than n/2 accounts among the collection of n accounts that all belong to the same user.

b. To answer the agency's question with O(nlog n) requests to the social networking company, we can use a divide-and-conquer algorithm. We first divide the set of accounts into two halves and recursively check whether there is a set of more than n/2 accounts that belong to the same user in each half.

If such a set exists in one half, we return it. Otherwise, we make n/2 requests to check whether accounts from one half belong to the same user as accounts from the other half.

If we find a set of more than n/2 accounts that belong to the same user, we return it. The algorithm terminates when the size of the set is 1. This algorithm requires only O(nlog n) requests to the company, which is more efficient than checking all possible pairs of accounts.

Write the c program


The function named findNote, which returns a student's letter grade according to the data(score out of 100, class average, standard deviation) sent to it

Answers

The findNote function takes three arguments: the student's score out of 100, the class average, and the standard deviation. It calculates the z-score of the student's score using the formula z = (score - avg) / stddev. Then, i

Here's a sample C program that implements the findNote function:

```
#include
#include

char findNote(int score, float avg, float stddev) {
   float z = (score - avg) / stddev;
   if (z >= 1.5) {
       return 'A';
   } else if (z >= 0.5) {
       return 'B';
   } else if (z >= -0.5) {
       return 'C';
   } else if (z >= -1.5) {
       return 'D';
   } else {
       return 'F';
   }
}

int main() {
   int score = 85;
   float avg = 75.0;
   float stddev = 10.0;
   char grade = findNote(score, avg, stddev);
   printf("The student's grade is %c\n", grade);
   return 0;
}
```

It uses a series of if-else statements to determine the corresponding letter grade based on the z-score. The function returns the letter grade as a char variable.

In the main function, we declare and initialize the variables score, avg, and stddev with some sample values. We call the findNote function with these values and store the result in the grade variable. Finally, we print the grade using printf function.
