Exam SSCP topic 1 question 1 discussion

Actual exam question from ISC's SSCP

Question #: 1
Topic #: 1

[All SSCP Questions]

A potential problem related to the physical installation of the Iris Scanner in regards to the usage of the iris pattern within a biometric system is:

A. concern that the laser beam may cause eye damage
B. the iris pattern changes as a person grows older.
C. there is a relatively high rate of false accepts.
D. the optical unit must be positioned so that the sun does not shine into the aperture.

Show Suggested Answer

Suggested Answer: D 🗳️
Because the optical unit utilizes a camera and infrared light to create the images, sun light can impact the aperture so it must not be positioned in direct light of any type. Because the subject does not need to have direct contact with the optical reader, direct light can impact the reader.
An Iris recognition is a form of biometrics that is based on the uniqueness of a subject's iris. A camera like device records the patterns of the iris creating what is known as Iriscode.
It is the unique patterns of the iris that allow it to be one of the most accurate forms of biometric identification of an individual. Unlike other types of biometics, the iris rarely changes over time. Fingerprints can change over time due to scaring and manual labor, voice patterns can change due to a variety of causes, hand geometry can also change as well. But barring surgery or an accident it is not usual for an iris to change. The subject has a high-resoulution image taken of their iris and this is then converted to Iriscode. The current standard for the Iriscode was developed by John Daugman. When the subject attempts to be authenticated an infrared light is used to capture the iris image and this image is then compared to the Iriscode. If there is a match the subject's identity is confirmed. The subject does not need to have direct contact with the optical reader so it is a less invasive means of authentication then retinal scanning would be.

Wikipedia - http://en.wikipedia.org/wiki/Iris_recognition
The following answers are incorrect:
concern that the laser beam may cause eye damage. The optical readers do not use laser so, concern that the laser beam may cause eye damage is not an issue. the iris pattern changes as a person grows older. The question asked about the physical installation of the scanner, so this was not the best answer. If the question would have been about long term problems then it could have been the best choice. Recent research has shown that Irises actually do change over time: http://www.nature.com/news/ageing-eyes-hinder-biometric-scans-1.10722 there is a relatively high rate of false accepts. Since the advent of the Iriscode there is a very low rate of false accepts, in fact the algorithm used has never had a false match. This all depends on the quality of the equipment used but because of the uniqueness of the iris even when comparing identical twins, iris patterns are unique.

now that they removed the comments for the products which is a very bad thing now i dont know what to buy based on user experience, non of these questions were in the SSCP exam and actually most of these questions are pretty hard and have a beating on you it is more aligned with CISSP like rodwave says. The actual exam was actually kind of easy. Examtopics was accurate with the comptia exams but not the SSCP. I wanted to go for some cisco certs too but since i cant read any real reviews about the products im highly skeptical with a purchase from examtopics anymore. those real customer comments really helped me do my purchases from examtopics :(

Just a heads up. When I took the SSCP exam there wasn't any questions from here. I would definitely say to treat this like an extra study guide and not try to remember any questions.

are the questions here helpful at all and relate to the content of the exam like the topics?

Not really for me. Honestly, I'd skip this just to save you some time. Its really bloated with questions that the SSCP didn't expect you to know. Probably aligns more for the CISSP. Anyway, I think Mike Chappele's last minute review guide for the sscp was definitely close to the level of knowledge they'd expect you to know for the exam. Nothing really in-depth.
