Biometric procedures

Biometry, voice recognition, fingerprint

Biometrics scan physiological and behavioral features of individuals for identification.

Physical features are:
finger print, hand shape, retina, iris and face

Behavioral features are:
Signature, voice, pressure intensity applied on keys, facial expression and way of walking

Application of biometry
Security systems use biometrics in two ways:

• Screening: Existing data are compared to a template in order to determine a possible identity. Screenings are used in the domain of access control, e.g., for computers or buildings.
• Identification: A more complex task, as a previously compiled data base has to be searched. This procedure is applied when conducting a search based on biometric data.

Physical access
In the past, security systems used biometric techniques for access control. The new tendency is the use of biometrics for physically securing critical corporate/personal data or premises. Biometrics are a perfect means for surveillance. Applications monitoring access of critical corporate data are already implemented. In addition, development processes for prototypes, e.g. for international airports, are in full swing. Check-in of persons air travelling (without luggage) on a regular basis is to be automated further on. In many airports, unmanned systems are beyond test stage and have been established as a real business models.

E-commerce
E-Commerce integrates the applications of biometrics and Smart Cards in order to improve the verification of the user identity. Especially banks are interested in this combination; by providing secure services they intend to ensure customer loyalty .

The development process of voice recognition is further on in full activity. One application is homeshopping by phone.

As demonstrated, biometric procedures serve as another means of protecting data or premises from unauthorized acces in the context of applications, no matter whether the connection to the system is mobile or wired. 

For instance, a mobile terminal furnished with a fingerprint sensor can secure downstream systems.

Voice as a major personal feature is another well-suited means for online authentication. Voice recognition as opposed to fingerprint sensors generally is a server-based solution, but it outplays the latter by being applicable to any voice-driven terminal device available on the telecommunication market. The application SWISSIdent provides biometric protection by using the voice as a key.

When it comes to security solutions, it is important to consider the context and the customer-specific demands.
