In 1-2 pages, identify a social networking technology and identify at least 10 security and/or privacy risks the technology has

algol13

Answer:

One of the biggest social media giants has faced many such security and privacy risks in the past 3 years. 10 are listed below:

1. No one can forget the New Zealand attack on the mosque, and it was telecast live via it. And that is certainly a security risk. And if someone is able to stream live, the AI is in question definitely as this cannot be telecast.

2. Can you forget the various US shooting cases in the past 5 years? And many out of them where telecast lives on it. Again the AI, and the authentication is in question.

3. Many evils have many times advertised itself through it, and that is a security risk. This put up the question on the Data Scientists of the company.

4. It's a huge data on it, and many users have been able to misuse it, and that is a security risk. This put up the question mark on the application of the Big Data.

5. Once, the UK parliament questioned it to sell the secret data, and that was a privacy risk.

6. An Engineer was caught negotiating to sell secret users data to a third party, and that is a privacy risk as well as a question on management technology, as its possible now to check these kind of frauds.

7. Its accounts have been hacked many times, as well as millions of user-profiles, were stolen. This is a security and privacy risk.

8. Its data is still not safe as evils have proved they can break the authentication. However, it has reacted well, and they look like being a safe destination now.

9. Once, someone from Russia was caught collecting a lot of data from it. That was a security and privacy risk. And surely if someone is uploading a lot of complicated and confidential data, must be checked through proper AI implementation.

10. In India too there have been claims that a lot of personal information during elections 2014 was sold. That was a security and data risk. And the data scientists were proved vulnerable again. Its quite sure hence, a lot of work has to be done in Data Science and Artificial intelligence still.

However, its owner is one of the finest souls on earth. He donated all his money when he was blessed with a child. Some out of his team cheated, and else some technology failure or the huge amount of data was the reason for the fault. However, other companies are also facing such problems. And hence, he cannot be blamed for this. And the company now definitely has recovered from the nightmare that they faced in the past 3 years.

The answer is self explanatory.

According to your textbook, the three major criteria against which to test documents that you locate on the Internet are authors

pantera1 [17]

Answer:

The following statement is False.

Explanation:

Because asper textbook there are only one main criteria against the test documents that find on the internet i.e., authorship. So, that's why the following given statement is false. The graphic and the interactivity depends on the quality of the document this options do not come under the criteria to test the document.

Design and implement an algorithm that gets as input a list of k integer values N1, N2,..., Nk as well as a special value SUM. Y

satela [25.4K]

Answer:

Follows are the code to this question:

def FindPair(Values,SUM):#defining a method FindPair

found=False;#defining a boolean variable found

for i in Values:#defining loop for check Value

for j in Values:#defining loop for check Value

if (i+j ==SUM):#defining if block that check i+j=sum

found=True;#assign value True in boolean variable

x=i;#defining a variable x that holds i value

y=j;#defining a variable x that holds j value

break;#use break keyword

if(found==True):#defining if block that checks found equal to True

print("(",x,",",y,")");#print value

else:#defining else block

print("Sorry there is no such pair of values.");#print message

Values=[3,8,13,2,17,18,10];#defining a list and assign Values

SUM=20;#defining SUM variable

FindPair(Values,SUM);#calling a method FindPair

Output:

please find the attachment:

Explanation:

In the above python code a method, "FindPair" is defined, which accepts a "list and SUM" variable in its parameter, inside the method "found" a boolean variable is defined, that holds a value "false".

Inside the method, two for loop is defined, that holds list element value, and in if block, it checks its added value is equal to the SUM. If the condition is true, it changes the boolean variable value and defines the "x,y" variable, that holds its value.
In the next if the block, it checks the boolean variable value, if the condition is true, it will print the "x,y" value, otherwise, it will print a message.

What would you have to know about the pivot columns in an augmented matrix in order to know that the linear system is consistent

Scrat [10]

Answer:

The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

$rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)$

Then satisfying this theorem the system is consistent and has one single solution.

Explanation:

1) To answer that, you should have to know The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

$rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)$

$rank(A)$

Then the system is consistent and has a unique solution.

$\left\{\begin{matrix}x-3y-2z=6 \\ 2x-4y-3z=8 \\ -3x+6y+8z=-5 \end{matrix}\right.$

2) Writing it as Linear system

$A=\begin{pmatrix}1 & -3 &-2 \\ 2& -4 &-3 \\ -3 &6 &8 \end{pmatrix}$ $B=\begin{pmatrix}6\\ 8\\ 5\end{pmatrix}$

$rank(A) =\left(\begin{matrix}7 & 0 & 0 \\0 & 7 & 0 \\0 & 0 & 7\end{matrix}\right)=3$

3) The Rank (A) is 3 found through Gauss elimination

$(A|B)=\begin{pmatrix}1 & -3 &-2 &6 \\ 2& -4 &-3 &8 \\ -3&6 &8 &-5 \end{pmatrix}$

$rank(A|B)=\left(\begin{matrix}1 & -3 & -2 \\0 & 2 & 1 \\0 & 0 & \frac{7}{2}\end{matrix}\right)=3$

4) The rank of (A|B) is also equal to 3, found through Gauss elimination:

So this linear system is consistent and has a unique solution.
