Use the Internet and other sources to research the two disadvantages of standard biometrics: cost and error rates. Select one st

andard biometric technique (fingerprint, palm print, iris, facial features, etc.) and research the costs for having biometric readers for that technique located at two separate entrances into a building. Next, research ways in which attackers attempt to defeat this particular standard biometric technique. Finally, how often will this technique reject authorized users while accepting unauthorized users compared to other standard biometric techniques

Answer:

Check the explanation

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.

Kindly check the attached image below.

I need help solving this problem on Picoctf. The question is What happens if you have a small exponent? There is a twist though,
soldi70 [24.7K]

Explanation:

Explanation:

RSA encryption is performed by calculating C=M^e(mod n).

However, if n is much larger than e (as is the case here), and if the message is not too long (i.e. small M), then M^e(mod n) == M^e and therefore M can be found by calculating the e-th root of C.

Help to how to write pseudo code to insert a new node to Binary Search Tree. Using C++.
dimulka [17.4K]

Answer:

Let the function be Node* ins(Node *root,int k)

if root node is NULL then return new node with data equal to k.

If the k <root->data

root->left=ins(root->left,k);

else if k >root->data

root->right =ins(root->right,k);

At last return root.

Explanation:

Node is always inserted at the at the leaf node.We will search k in the tree if we hit a the leaf node the new node is inserted as the child of the leaf node.

What's a good drawing tablet?
DENIUS [597]

Answer:

Wacom Intuos S

Explanation:

If you're looking for a good tablet that isn't too expensive the Wacom Intuos S is a great starter, I personally use it and really enjoy it. It doesn't have a graphic screen. If you're looking for one with a graphic screen get the Wacom Cintiq 22, It's expensive but great quality. Most tablets with a graphic screen are this expensive though. But if you REALLY want one with a graphic screen that isn't TOO expensive I recommend the HUION Kamvas pro 12.

Hope I could help!
