Biometrics - Fingerprint recognition

Fingerprint recognition or fingerprint authentication refers to the automated method of verifying a match between two human fingerprints. Fingerprints are one of many forms of biometrics used to identify an individual and verify their identity. This article touches on two major classes of algorithms (minutia and pattern) and four sensor designs (optical, ultrasonic, passive capacitance, and active capacitance).

The analysis of fingerprints for matching purposes generally requires the comparison of several features of the print pattern. These include patterns, which are aggregate characteristics of ridges, and minutia points, which are unique features found within the patterns. It is also necessary to know the structure and properties of human skin in order to successfully employ some of the imaging technologies.

The three basic patterns of fingerprint ridges are the arch, loop, and whorl. An arch is a pattern where the ridges enter from one side of the finger, rise in the center forming an arc, and then exit the other side of the finger. The loop is a pattern where the ridges enter from one side of a finger, form a curve, and tend to exit from the same side they enter. In the whorl pattern, ridges form circularly around a central point on the finger. Scientists have found that family members often share the same general fingerprint patterns, leading to the belief that these patterns are inherited.

The major Minutia features of fingerprint ridges are: ridge ending, bifurcation, and short ridge (or dot). The ridge ending is the point at which a ridge terminates. Bifurcations are points at which a single ridge splits into two ridges. Short ridges (or dots) are ridges which are significantly shorter than the average ridge length on the fingerprint. Minutiae and patterns are very important in the analysis of fingerprints since no two fingers have been shown to be identical.

A fingerprint sensor is an electronic device used to capture a digital image of the fingerprint pattern. The captured image is called a live scan. This live scan is digitally processed to create a biometric template (a collection of extracted features) which is stored and used for matching. This is an overview of some of the more commonly used fingerprint sensor technologies.

Bracelet cell phone from Samsung

For all tech freaks and cell phone fans that enjoy extreme sports Samsungs has a new cell phone. It’s still an early design but interesting thing about this cell phone is that actually a cell phone and a bracelet that you can actually wear while performing all kinds of activities.

321 Water bottle wilt built-in self filter

Many people are drinking bottled water nowadays because they are suspicious of ingredients that might be hidden in regular tap water. Only downside of bottled water is that there are too many plastic bottles being used every day, but there are also all sorts of reusable bottles that have built in filters – its just that they never get noticed. Even if these bottles have existed for some time, none of them have had a design like this one.






























It is called 321 Water and it comes from the company called Half a Teaspoon. Interesting thing about these bottles is that they have their own water purifiers. Although it seems like nothing special you’ll have to see it to believe it, because these filters are looking like an alien tube. With the white design of the bottles and the light blue color of the alien tube filter these bottles look rather attractive. Design is simple and amazing but how do they work?

Simple enough, you just fill 321 Water bottle with tap water, insert the filter into the bottle and let the filter do all the work. It has carbon block so it will remove chlorine and all other unpleasant tastes leaving you with purified fresh water. It can be used more than 100 times and it can purify 50 liters of water. As for the price and release date, we should see these bottles in stores in before July but you can still per-order them for 44.60$ from the manufacturing company.

Document Management system

A document management system (DMS) is a computer system used to track and store electronic document or image of paper documents. The term has some overlap with the concepts of content management system. It is often viewed as a component of enterprise management system (ECM) systems and related to digital asset management, document imaging, workflow systems and records management systems.

Database Software

Datebase software is a set of data that has a regular structure and that is organized in such a way that a computer can easily find the desired information.Datebase also collection of clearly pieces of information, specially information that has been formatted in some specific way for use in analysis or making decision.

Word Processing

Word processing software is to create, edit, and print document.It also help users have the ability of creating and making any type of changes in the document. This document can also be saved changing at a later time or to be opened other computer useing the same word processor. Users can use this software to easily edited document, searched, and reprinted because it has replaced the typewritter.Word processing is performed on general purpose computers using this software such as Microsoft Word and WordPerfect.
