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

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.
