modalities in biometrics such as fingerprints‚ face‚ iris‚ etc.‚ fingerprints are the most widely used and have the longest history in real-world law enforcement applications. Research into automated fingerprint identification began in the 1960’s and the resulting AFIS (Automated Fingerprint Identification Systems) have been used worldwide with established dependability. Millions of identifications over a century of actual forensic history have clearly shown that fingerprints are unique and

Touch ID a nifty feature. Apple says it’s secure: Fingerprint data is stored on a quarantined section of the phone’s processor‚ doesn’t sync with iCloud‚ and is blocked from third-party use‚ but‚ do we really know if that will last for long before the next company like ‚ for example‚ Samsung goes to creates another‚ updated version‚ of the Galaxy this time with the Touch ID sensor. Biometric identification is a good thing—in theory. Fingerprints are one of the most foolproof identifiers we have

Comparison points must be perfectly matched for two fingerprints to be considered identical Who is a pioneer in fingerprint analysis? Describe a famous case that this person was involved in.

Hoang Ngo Lab 6 report Anita Dey Thursday 8am Abstract: We recently performed a liquid nitrogen experiment in finding the Latent heat of the substance. We isolated two parts of the experiment in order to find out how much evaporation of the liquid nitrogen was from the surroundings B and how much evaporation from the electricity G. 1. When a substance is undergoing a phase transition‚ more heat (energy) is being added to the Substance but its temperature (a way of measuring its energy) is not

Sameera Raziuddin Latent Heat of Fusion April 11‚ 2011 Abstract: A calorimeter‚ water at room temperature‚ ice‚ and a Pasco GLS Explorer were used in combination with a known value of the latent heat of fusion to create and carry out an experiment to determine the mass of an unknown amount of ice. Using the formula for latent heat of fusion‚ the mass of the ice was calculated to be 45.76g. The error of the carried out experiment was calculated to be 20.06%. Introduction:

Civil Engineering Department‚ College of Engineering‚ Adamson University Abstract The purpose of this experiment is to determine the Latent Heat of Fusion of ice. In this experiment‚ the heat of fusion of ice will be determined by using the method of mixtures (Quantity of heat lost = Quantity of heat gained). Introduction When a substance changes phase

The Chemistry of Latent Fingerprints KEY Chemical Reaction Silver nitrate (AgNO3) can react with the salt (NaCl) left from the perspiration on the friction ridge skin to form solid silver chloride (AgCl) and sodium nitrate. The silver chloride can then be converted to silver oxide (Ag2O)‚ which is dark in color and can be more easily seen. Challenge Suppose the fingerprint processing technique that uses silver nitrate to react with the salt from perspiration produced 5.8 x 10-2 grams of silver

Fingerprint analysis had been used for over 100 years in law enforcement. The first forensic organization to identify criminals was established in 1915. In that time fingerprints were being used to track a criminal’s record‚ including previous arrests to decide decisions like sentencing‚ probation‚ and pardoning decisions. As technology has advanced so has our use for fingerprints. We have now been able to use fingerprints for background checks‚ biometric security (a way to access computers‚ electronic
