It is also essential to know the structure and properties of human skin to successfully employ some of the imaging technologies. There are many human biometric features that can be used to confirm the identity ,such as voice, hand geometry, face, finger print and retinal pattern of eye. Among all these features, finger print matching is the most popular and reliable biometric technique for automatic personal identification.

Today, automatic fingerprint recognition technology can be found in a wide range of civilian applications.

Measured the distance moved by each band from edge of the loading well. Draw a graph of log10 Mw of standard DNA marker vs the distance travelled by each of them 12. From the distance travelled by supplied DNA preparation, determine its molecular weight using the calibration

Topic: B2 – Analysis of Materials – Fingerprints Question: What is dactylography? What are fingerprints mainly composed of? Explain the 3 types of fingerprints forms when they are found. What do the ridges on our fingers help us do?

1.1 INTRODUCTION In modern day, vehicles anti-theft system is our prime important duty to secure our vehicle by the means of fingerprinting. The main focus while developing the vehicle anti-theft system is to protect our system from theft by providing the anti-theft protection. For the protection, first we should restrict the unlocking of vehicle, only to the authorized persons have this ability to unlock the car without the use of keys, once it has identified by the Fingerprint sensor. The Fingerprint of the owner and other authorized persons are stored into the database beforehand and at the time of starting engine of the vehicle, scanned fingerprints are being crosschecked with the database.

Biometric face recognition technology has received significant attention in the past several years to use human face as a key to security. Both law enforcement and non-law enforcement are its application. Face recognition system comprises of two Categories: verification and identification. Face Verification is Done in 1:1 match ratio. It is utilized to looks at a face pictures against a Template face pictures, whose identity being claimed.

Areas of future use contain Internet transactions, workstation and network access, telephone transactions and in travel and tourism. There have different types of biometrics: Some are old or others are latest technology. The most recognized biometric technologies are fingerprinting, retinal scanning,hand geometry, signature verification, voice recognition, iris scanning and facial

In today's world the life is very fast we want to do everything so quickly and easily without putting much physical and mental effort. With the advancement of technology, we are provided with higher level of knowledge through the invention of different devices. However, each technological innovation has its pros and cons. One of the emerging usages for biometric security system is in smartphones and computers that we are using today. Also, today we cannot think of living without smart phones and devices as they have become a vital part of our life.

Background Ancient archeological artifacts and historical items have been discovered to still retain a large number of fingerprints on them. Since this was discovered significant strides in fingerprinting and identification have been made. In 1788 a detailed description of anatomical formations of fingerprints was made. Then in 1823 fingerprints began to be classified into nine categories, and by the 19 the century Sir Francis Galton had developed analytical methods for fingerprint matching. As the criminal justice system evolved, there arose the need for criminals to be uniquely identified by some physically identifiable trait.

"Super Glue" method is used for metal and glass samples and "Ninhydrin" method is used for paper samples which have been exposed to different temperatures to investigate whether fingerprints would develop or not. High quality scaled photo shooting and image intensifying (Photoshop) process is applied to each sample in order to assess if they are suitable for identification or not. Results of fingerprint samples on different surfaces belonging to each volunteer are classified basing on the classification system used in Turkey and taking at least 13 fingerprint characteristics with regard to they are classifiable or not. When we assess the study in terms of fingerprint development: · It is determined that fingerprints on glass surfaces are more suitable for comparison than the ones on metal and paper surfaces.. Chart 1: Assessment of fingerprints with regard to surface types and time · When the total number of comparable fingerprints is considered; it is found that the number of comparable fingerprints decreases from month 0 to month

1. One new technology that is emerging in biometrics would be facial thermography. Facial thermography uses highly distinctive heat patterns created the branching off of blood vessels. These patterns, also called thermograms, are even different in identical twins. The advantage that facial thermography has over other emerging technologies is that it doesn’t require any physical contact to the person.

For an analyst to match the specific print, they will use the ridge characteristics to identify specific points on a suspect fingerprint which the same information in a known fingerprint already in the database (Koehler, 1991). For example, if an analyst were to compare a fingerprint from a crime scene to a fingerprint already in the database, they would first have to collect known prints with the same general pattern type. Next, the analyst would use a loupe to compare the fingerprints side by side to identify certain information within the details that match. If enough minutiae correlate, the fingerprints are then determined to be from the same

By considering the factors affecting fingerprint development, three young and three middle-aged individuals are chosen to obtain fingerprints. Fingerprint development process of study is conducted in laboratories of the Institute of Forensic Sciences, Istanbul University with the contributions of fingerprint development laboratories of Istanbul Provincial Security Directorate, Department of Crime Scene Investigation. Investigation period of this study conducted by using the modelling method and the study lasted nine months. Preparation of the Samples:

Biometrics is the application of statistical analysis to biological data. When applying the use of biometrics to the healthcare industry you are able to use multiple sources of biological data to secure every source. However, the healthcare system it is broken down into “four “nested” levels: (1) the individual patient; (2) the care team, which includes professional care providers (e.g., clinicians, pharmacists, and others), the patient, and family members; (3) the organization (e.g., hospital, clinic, nursing home, etc.) that supports the development and work of care teams by providing infrastructure and complementary resources; and (4) the political and economic environment (e.g., regulatory, financial, payment regimes, and markets),

INTRODUCTION Phonocardiogram is a physiological signal that results from the vibrations created by closure of heart valves and it represents the recording of the heart sound signal. A normal cardiac cycle is comprised of two major sounds- first sound (S1) and the second heart sound (S2). The first heart sound has four components in it, due to the closure of AV and semilunar valves. The second heart sound has two components, one due to closure of aortic valve and another due to closure of pulmonary valve (Rangayyan, R.M and Lehner ,R.J (1988). In some case a third heart sound (S3) may be heard, which is corresponding to sudden termination of the ventricular rapid filling phase.
