The world has 25% of the people who suffers with hearing loss says a world census. Due to the issues in fitting, the hearing aid cannot solve those problems completely-it continues. Since the hearing aids are all mostly of a standard form, it doesn’t suit to unique ear of the user. To resolve this...
From the previous articles, an idea on Palm or vein biometrics can be clearly studied. But, the major disadvantage in palm or vein biometrics is that the movement or motion of the hand may give slightly a wrong authentication. The size of the palm or vein scanner is also large when compared with the...
Spoofing is a class of attack on a biometric security system where a malicious individual attempts to circumvent the correspondence between the biometric data acquired from an individual and the individual itself. That is, the malicious individual tries to introduce fake biometric data into a system...
Keystroke Dynamics: Keystroke dynamics is an automated method of examining an individual’s keystrokes on keyboard. This technology examines dynamics such as speed and pressure, the total time of typing a particular password and the time that a user takes between hitting keys - dwell time (the length...
Identification with Deep Tissue Illumination A relatively new technique that involves illumination of human tissue by specific lighting conditions and the detection of deep tissue patterns based on light reflection. The technique is claimed to have less susceptibility for spoofing than other forms of...
This method works by taking a tissue sample from an individual and then sequencing and comparing short segments of DNA.DNA sampling is rather intrusive at present and requires a form of tissue, blood or other bodily sample. This method of capture still has to be refined. Fig -Tissue Sampling So far,...
Palm Print Technology Palm print verification is a slightly modified form of fingerprint technology. Palm print scanning uses an optical reader very similar to that used for fingerprint scanning; however, its size is much bigger, which is a limiting factor for use in workstations or mobile devices Vein...
Voice recognition differs from most other biometric models in that it uses acoustic information instead of images. Each individual has a unique set of voice characteristics that are difficult to imitate. Human speech varies based on physiological features such as the size and shape of an individual’s...
Iris Scanning: Iris scanning is a newer technology than retina scanning. The iris consists of the multicolored portion of the eye that encircles the pupil, as shown in Figure. Iris patterns are complex, containing more raw information than a fingerprint. Depiction of an iris The iris completes development...
In many of the biometrics present, eye-based biometrics has traditionally been utilized in high-security applications such as - prisons, government agencies, and schools. Eye scanning comes in two forms: Retina scanning Iris scanning Retina Scanning: The first biometric eye-scanning technologies were...
