Biometric Template Protection Using Universal Background Models: An Application to Online Signature
No full textData security and privacy are crucial issues to be addressed for assuring a successful deployment of biometrics-based recognition systems in real life applications. In this paper, a template protection scheme exploiting the properties of universal background models, eigen-user spaces, and the fuzzy commitment cryptographic protocol is presented. A detailed discussion on the security and information leakage of the proposed template protection system is given. The effectiveness of the proposed approach is investigated with application to online signature recognition. The given experimental results, evaluated on the public MCYT signature database, show that the proposed system can guarantee competitive recognition accuracy while providing protection to the employed biometric data

Port-Access cardiac surgery: from a learning process to the standard.
No full textBackground: Port-AccessTM surgery has been one of the
most innovative and controversial methods in the spectrum
of minimally invasive techniques for cardiac operations and
has been widely used for the treatment of several cardiac diseases.
The technique was introduced in our center to evaluate
its efficacy in reproducing standardized results without an
additional risk.
Methods: Endovascular cardiopulmonary bypass (CPB)
through femoral access and endoluminal aortic occlusion
were used in 129 patients for a variety of surgical procedures,
all of which were video-assisted. A minimal (4-6 cm) anterior
thoracotomy through the fourth intercostal space was used in
all cases as the surgical approach.
Results: More than 96% of the planned cases concluded
as true Port-AccessTM procedures. Mean CBP and crossclamp
times were 87.2 min. ± 51.2 (range of 10-457) and
54.9 min. ± 30.6 (range of 10-190), respectively. Hospital
mortality for the overall group was 1.5%, and mitral valve
surgery had a 2.2% hospital death rate. The incidence of early
neurological events was 0.7%. Mean extubation time, ICU
stay, and total length of hospital stay were 5 hours ± 6 hrs.
(range of 2-32), 12 hours ± 11.8 hrs. (range of 5-78), and
7 days ± 7.03 days (range of 1-72), respectively.
Conclusions: Our experience indicates that the Port-
AccessTM technique is safe and permits reproduction of standardized
results with the use of a very limited surgical
approach. We are convinced that this is a superior procedure
for certain types of surgery, including isolated primary or
redo mitral surgery, repair of a variety of atrial septal defects
(ASDs), and atrial tumors. It is especially useful in high-risk
patients, such as elderly patients or those requiring reoperation.
Simplification of the procedure is nevertheless desirable
in order to further reduce the time of operation and to
address other drawbacks
