The market is flooded with security systems that claim to provide optimal security and safety. Biometrics is a type of security system that uses a person's unique characteristics, like fingerprints and eye retina, as a purpose of identification and security. In the latest in biometrics, researchers are developing a security system that uses an emotional fingerprint.

Most biometric security systems use a combination of a password or personal identification number with a fingerprint or retina scan to allow individuals access to an office, computer, or secure places. But Violeta Tulceanu of the University of Iasi is developing a biometric security that adds an emotion detector.

The concept for this security system is published in the International Journal of Advanced Intelligence Paradigms. Violeta Tulceanu describes that the security system is first trained to recognize a user's emotional fingerprint. These emotional fingerprints are based on the user's brainwave patterns that result from emotional stimulation using the abstract concept as auditive stimuli.

The emotional states of the user are matched to a pre-determined pattern and then compared with a particular configuration of the system that will either allow or not allow the user access to the resources. When the user next asks to be given access to the resources, the system then just analyzes the user's current brainwave activities and matches it to the emotional fingerprint to determine if the user can be granted access or not.

By scanning the brainwave activities of an individual, the biometric system can not only determine if the individual can be given access to resources but also determine if in the current emotional state of the user, will he or she be using the given resources responsible or acting in his own terms.

Tulceanu believes this kind of biometric system using an emotional fingerprint has different kinds of application especially in the field of the military. Future versions of the biometrics include the ability to analyze the current brainwave activities of the user to determine to assess the mental state of the user.
