Explanation:
Selecting the bio-metric technique fingerprint, it requires a scanner to read the fingerprint The cost for a scanner is in between 1000 and 5000 Placing two scanners at two entrance of office win cost bellow 10,000 So the cost needed for this technique is medium as compared with other bio-metric techniques
Attacks on this technique can be in saner, channel from scanner to feature extractor, in feature extractor, way in between feature extractor and marcher, in marcher, in database etc this attacks can be protect by using security methods such as cryptography, hashing, watermarking, noses etc
By using watermarking, cryptography and stenography methods, fingerprint has less false detection rate I e it gives high accuracy
I recommend fingerprint technique. Because of it is a standard technique, it has good accuracy and cost is less, and easy to handle, and it is taking small storage space in database.

Answer:
a. partial interval
Explanation:
Partial Interval data recording method of data collection involves recording whether an event occurs or does not during a defined interval.
It is different than <em>whole interval</em> data recording because partial interval doesn't occur throughout the entire interval.
In partial interval recording, <em>discrete behaviors</em> are observed. For example, this kind of behavior can be a person swearing or hitting to someone, a student participating in class discussions etc.
Answer:
import java.util.Scanner;
public class HollowSquare
{
public static void main(String args[])
{
Scanner scan = new Scanner(System.in);
int size;
System.out.print("Enter the size : ");
size = scan.nextInt();
if(size>=1 && size<=20)
{
for(int i=0; i<size; i++)
{
for(int j=0; j<size; j++)
{
if(i==0 || j==0 || i==size-1 || j==size-1)
System.out.print("*");
else
System.out.print(" ");
}
System.out.println();
}
}
else
System.out.println("Invalid size.");
}
}
