The absence of probable-lie comparison questions in an EyeDetect test eliminates concerns about any overlap that might occur between “relevant” and “comparison” questions (see “How is the polygraph typically used? What is the average accuracy for those uses?” above). The reactions to two sets of “relevant” questions are compared and each relevant issue serves as
When a deceptive person is devising a story to tell a lie, there’s an increase in cognitive load, or brain activity. If someone has the capacity to create a story without increasing how the brain reacts to this process, then that person will appear less deceptive. The pupils react involuntarily to an increase in cognitive
If EyeDetect and polygraph are used together, the probability of a false negative error is greatly diminished. Note: False negative means a deceptive person is categorized as truthful. EyeDetect primarily measures cognitive processes and the polygraph primarily measures emotional responses. As such, the two tests would be relatively independent and would provide complementary information about
The polygraph exam typically has two main uses: for incident-specific questioning, like the police use in investigations; and for screenings, such as the ones employed by government agencies. 1) In criminal investigations in the U.S., the polygraph is used to determine if statements by suspects concerning a specific crime are truthful or deceptive. The polygraph
EyeDetect can be used to replace in some circumstances and/or can complement the polygraph. In reality, EyeDetect is the perfect add-on service for a polygraph company. Studies show that the polygraph can be very accurate for event-specific questioning (a specific line of questioning). However, studies also show that EyeDetect has shown a superior level of
Yes. If an organization wishes to protect the identity of an examinee for purposes of reporting testing results, during registration prior to taking a test, the Test Proctor would provide an identifying number rather than a person’s name. In addition, the Test Proctor can elect to not take a photo of the person being tested.
To store and process user data collected during testing, Converus uses standalone (non-hosted) servers that are owned by Converus, and not owned by the data center. Access to these servers is controlled by a firewall and incoming web traffic is monitored for threats. All servers are housed in a private, locked rack in a SSAE
The Converus Dashboard web application is only accessible using two-factor authentication. All access to the dashboard is done through SSL. Only authorized users of an account with applicable rights can access the dashboard.
Each EyeDetect station comes with a secure external hard drive manufactured by DataLocker. The DataLocker is 256-bit AES encrypted and FIPS 140-2 validated. All test data is stored on the DataLocker and can only be accessed by users that enter the key to unlock the hard drive. Test data is encrypted using a unique key
Polygraph machines sense changes in glucocorticoid (hormone) levels, which initiate chemical reactions such as changes in respiration, heart rate and skin conductance (a moisture buildup under skin). Thus, a polygraph measures physiological changes when under the stress of questioning. That questioning is intended to determine whether a person is lying or being truthful. EyeDetect measures
