What does the IDesia BioDynamic Signature™ actually measure?
IDesia’s BDS™ engine operates using electrical bio-signals measured from two fingers of the user's hands.  Human body functions are controlled by electric signals such as brain waves, heart, muscles and nerve signals. These bio-signals are emitted from deep within the body and are captured by touching two metal plates which relay the signals to a sensitive, low-noise bio-signal amplifier.

How does one enroll in the system, and how long does it take?
The user simply places any two of his/her fingers on the sensors 2-3 times, each time for 10 seconds. The total enrollment time is up to 30 seconds. BDS™ touch sensors require only a simple touch and are not dependent on exact finger placement or on the use of the same fingers in enrollment and verification. Any finger may be used without degrading the performance. BDS™ authentication sensors have extremely high first-try success rates; there is no need for training or practice.

Does the user feel something when touching the contacts/sensor?
The signals are generated by our body and the measurement is completely passive and therefore does not cause the user any sensation whatsoever.

Can this information be used for medical diagnostics or other purposes?
No. The bio-signals picked up by the sensor are used to extract electrical micro-features which are highly subject-specific. These electrical micro-features constitute a stable “signature” which does not reflect the user's physiological condition and therefore has no value to medical diagnostics.

If the user is ill, taking medication or other drugs, will this affect the performance of the BDS engine?

The technology is generally not sensitive to one’s physiological condition and therefore not sensitive to illness.  However, certain medications or acute medical conditions may influence a user’s ability to operate the system adequately and may cause false rejections. However, BDS™ is much less sensitive to changes than other biometric technologies. For example, a simple scratch will impair fingerprint identification.

Will the BDS™ engine recognize a user 5, 10 or 25 years from now?
As with all biometric technologies, the issue of template aging is of importance.  Under normal conditions, one’s BDS™ adult signature should remain steady and operational for several years.  However, in some rare cases, it may require that the user renew his/her signature.

What kind of conductive material is suitable for the sensor contacts?
The sensor contacts are made of a conductive substance (usually silver based) covered with a thin layer of silver-chloride.  The silver-chloride is a known bio-compatible substance that does not interact with the skin and does not cause allergies.  It has been used in medical applications for many years.

Once an individual is in the system, how long does the BDS™ engine take to verify an individual?
Verification can take between 2-10 seconds, depending on the required level of security as well as on the quality of contact with the sensor.  Selecting standard security settings and maintaining good contact with the sensors provide verification within 2-3 seconds.

What are the initial applications for IDesia’s BDS™?
Any portable electronics device is suitable, including laptops, keyboards, disks-on-key, mobile phones, PDAs, and credit or smart cards.
