Overview<\/h3>\n\n                    
\n                        The Headset is worn in the same manner as various augmented reality (AR) glasses. It includes\n                        five cameras, two speakers, two microphones, and a hackproof protective coating called a Chassis\n                        Intrusion Detector (CID) which prevents access to the electronics and the combiner. The test is\n                        viewed on a screen called a combiner which includes a Liquid Crystal Shutter (LCS). It is\n                        non-transparent during test taking but becomes transparent at other times.\n                    <\/p>\n                <\/div>\n\n

\n                        Two Iris Cameras<\/b> 
\n\nThese cameras image the student\u2019s eyes. They use iris recognition that recognizes, but does not store, the student\u2019s iris biometrics at the beginning of every test. Thereafter, it monitors the location of the eyeballs to detect switching of the glasses to another person or changing in position to enable viewing of the display by a hidden camera.\n                    <\/p>\n\n                <\/div>\n\n

\n                        One Forward Looking Camera<\/b> 
\n\n                        This wide-angle camera views what the student can see. It also can record what the\n                        student\n                        is doing with his\/her hands thus eliminating the possibility of student-to-3rd party\n                        communication e.g. via typing or writing. The headset image above shows only one forward\n                        looking camera, though an iteration to include two forward-looking cameras for greater\n                        visibility is in development.\n                    <\/p>

\n                            The contact microphone rests on the face or cheekbone of the test-taker where it differentiates between background sound and the test-taker speaking. A contact speaker periodically transmits a sound using bone conduction. If the contact microphone fails to record the speaker output, then the microphone is not properly mounted  most likely because it has been tampered with and the test, and the test can be interrupted. If test-taker talking is detected, a warning is provided and the test may be terminated.\n                        <\/p>\n\n\n                    <\/div>\n\n

\n                            To prevent the test-taker from reading the questions and answer choices to a 3rd party, a contact microphone is positioned against the head of the test-taker. A contact microphone is similar to a physician\u2019s stethoscope.\n                        <\/p>\n\n                    <\/div>\n<\/div>\n\n                <\/div>\n\n

The CID Barrier:<\/h4>\n                    <\/div>\n\n\n                    
\n                        The Chassis Intrusion Detector is a patented invention of SecureTest\u00ae. It is a\n                        thin sheet of plastic film wrapped around the electronics and a second sheet affixed to the\n                        combiner. The sheets contain a fine mesh of wires where the distance between the wires is\n                        less\n                        than the thickness of a human hair. If one were to tamper with the device, attempt to remove\n                        the\n                        CID, or drill through the film, the circuit would be broken and all the software,\n                        cryptographic\n                        keys and other information erased.\n                    <\/p>\n\n                <\/div>\n\n            <\/div>\n        <\/div>\n    <\/div>\n<\/section>\n\n\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"pages\/received.php","meta":{"footnotes":""},"class_list":["post-13","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/securetest.global\/en\/wp-json\/wp\/v2\/pages\/13","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/securetest.global\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/securetest.global\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/securetest.global\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/securetest.global\/en\/wp-json\/wp\/v2\/comments?post=13"}],"version-history":[{"count":157,"href":"https:\/\/securetest.global\/en\/wp-json\/wp\/v2\/pages\/13\/revisions"}],"predecessor-version":[{"id":876,"href":"https:\/\/securetest.global\/en\/wp-json\/wp\/v2\/pages\/13\/revisions\/876"}],"wp:attachment":[{"href":"https:\/\/securetest.global\/en\/wp-json\/wp\/v2\/media?parent=13"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
