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.

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.

Blogger

Major events in the history of Blogger:
- On August 23, 1999, Blogger was launched by Pyra Labs. As one of the earliest dedicated blog-publishing tools, it is credited for helping popularize the format.
- In February 2003, Pyra Labs was acquired by Google under undisclosed terms. The acquisition allowed premium features (for which Pyra had charged) to become free. About a year later, Pyra Labs' co-founder, Evan Williams, left Google.
- In 2004, Google purchased Picasa; it integrated Picasa and its photo sharing utility Hello into Blogger, allowing users to post photos to their blogs.
- On May 9, 2004, Blogger introduced a major redesign, adding features such as web standards-compliant templates, individual archive pages for posts, comments, and posting by email.
- On August 14, 2006, Blogger launched its latest version in beta, codenamed "Invader", alongside the gold release. This migrated users to Google servers and included some new features.
- In December 2006, this new version of Blogger was taken out of beta.
- By May 2007, Blogger had completely moved over to Google operated servers.
Blogger was ranked 16 on the list of top 50 domains in terms of number of unique visitors in 2007.[4][dated info]
As part of the Blogger redesign in 2006, all blogs associated with a user's Google Account were migrated to Google servers. Blogger claims that the service is now more reliable because of the quality of the servers.[5]
Along with the migration to Google servers, several new features were introduced, including label organization, a drag-and-drop template editing interface, reading permissions (to create private blogs) and new Web feed options. Furthermore, blogs are updated dynamically, as opposed to rewriting HTML files.
In a version of the service called Blogger in Draft,[6] new features are tested before being released to all users. New features are discussed in the service's official blog.
In September 2009, Google introduced new features into Blogger as part of its tenth anniversary celebration. The features included a new interface for post editing, improved image handling, Raw HTML Conversion, and other Google Docs-based implementations, including:
- Adding location to posts via geotagging.
- Post time-stamping at publication, not at original creation.
- Vertical re-sizing of the post editor. The size is saved in a per-user, per-blog preference.
- Link editing in Compose mode.
- Full Safari 3 support and fidelity on both Windows and Mac OS.
- New Preview dialog that shows posts in a width and font size approximating what is seen in the published view.
- Placeholder image for tags so that embeds are movable in Compose mode.
- New toolbar with Google aesthetics, faster loading time, and "undo" and "redo" buttons. Also added was the full justification button, a strike-through button, and an expanded color palette.
The new post editor was criticized for being less reliable than its predecessor.[7]
Why Do People Use Online Social Networking?
Online social networking can provide a valuable way for people to connect, share interest, and stay in touch with people across the miles. The reasons people use online social networking are:
1) Helping People Connect
The reason so many people use online social networking is that it provides a way for people to connect. You can keep in touch with friends, share information about events and even help one another with homework with online social networking tools.
With online social networks, you can get in touch with old friends and make new ones. Most social networking Web sites have tools that enable you to track down old friends and colleagues. You can also use an online social network to make new friends with similar interests. Online social networking is a great way to expand your social circle and get in touch with people you otherwise wouldn’t speak with regularly, or at all.
2) Collaborating at Work
Social networking tools are also very useful for work. If you're looking for a job, you can use it to get references from old coworkers. You can also connect with other people who work for the same company, or in the same industry. Managers looking to hire people with specific skills can then find you using social networking tools.
Both businesses and individuals use social networking for marketing purposes. They use it to advertise new products and deals, to stay in touch with customers or to follow other people who might have items or offerings they could use. Social networking can be a great forum for viral marketing, but it's important to be clear that you're marketing a product or the message won't get through.
3) The Quest for Popularity
Along with the positives, social networking carries a few negatives. Some people see social networking as a big popularity contest. These people use social networks to grab as many friends as possible, and people with few friends may be seen as losers or people with poor social skills. However, friends’ lists in online social networks can be very misleading, as many of those people may simply be acquaintances who are also looking to collect and acquire online friends.
4) Hiding from Real Life
People with poor social skills may use online social networks to withdraw from real life. They may feel less pressured in online interactions, and rely more and more on online tools to interact with friends and peers. Using online social networks and withdrawing from real life interactions is a real danger, and parents must be vigilant to ensure kids are still spending quality time with friends in person. There's simply no substitute for spending time together with friends in the real world.
