Smart Crawler, For Efficient Harvesting Deep Web Interfaces Essay

One of the most revolutionary invention is the Internet, and throughout the years it has evolved. People throughout the world use the Internet to access their mail, shopping, communication, and social media. Therefore, Some infrastructure components that are important for providing the surface web to the public are providing people to find and access what they want. Moreover, the surface web enables people to access everyday Internet use such as Facebook, Twitter, and other Social Media platforms. Surface Web is a “portion of the World Wide Web that is readily available to the general public and searchable with standard web search engines” It is mind-blowing on how big the web is and it is hard to believe that the searched contents are limited. JJ Rosen stated that “Google has placed in its index an estimated 35 trillion Web pages across the Internet worldwide. While this is an amazing statistic, believe it or not, 35 trillion is barely the tip of the iceberg. Google's index represents only an estimated 4 percent of the information that exists on the Internet”. Therefore, ninety six percent of contents are not commercialized by Google or Bing's known as Deep Web and are harder to access than Surface Web. Software servers are able to identify billions of pages, but search engine like Bing or Google that the ability to optimize the pages that are relevant to what is being searched. Furthermore, the Deep web is not indexable by search engines and as stated in the book that “

The deep web is really anything that can’t been indexed, unsearchable and unreachable, by search engines. Now, the deep web is often confused with the dark web, giving the deep web a bad reputation. People associate these types of websites with criminal activities, such as drugs.

A Web crawler, sometimes called a spider, is an Internet bot that systematically browses the World Wide Web, typically for the purpose of Web indexing. Crawlers can validate hyperlinks and HTML code. They can also be used for web scraping. Crawlers consume resources on the systems they visit and often visit sites without approval. Issues of schedule, load, and "politeness" come into play when large collections of pages are accessed. Mechanisms exist for public sites not wishing to be crawled to make this known to the crawling

The web has ‘taken over’ 81% of Americans lives! Most of us don't ever think about where the data we research is stored and what can be done with it. We would like to believe that searching the web as freely as we do will be a lifelong privilege. That carriers and companies cannot be biased and raise the fees for faster responses or even manipulate your searches. But there are no such promises.

The media’s skewed outlook and reports on the deep web has affected the way the majority of people view this resource that is inherently not a bad tool. The media also misrepresents the deep web by confusing it with the darknet and giving false information about the two. It is easy to get caught in the wave of horror stories that appear in magazines and online content about the deep web and the darknet, but more often than not the deep web is doing more good than is portrayed by the media. The advances in cryptography that is being used within the deep web and the darknet are creating a safer environment for reporters and political activists; even the simple internet user needs cryptography to protect their information stored in the deep web.

My interest in video gaming is what first brought the Dark Web in to my attention and I find myself not only fascinated but terrified by this network of information that lies under our current internet. I’ll introduce the deep web in it’s entire before I focused in on particular forums and elements such as the bitcoin, /b/, Silk Road, and Marianas web. I’ll address the effect that the dark web has on the war against drugs as well as why, even though authorities know that this form of drug peddling exists why they haven’t stepped in on the activities to ry and put a stop to it.

When many student go on and search on the web, the web can bring up false information which can lead the student to get the wrong ideas. Search engines are so simple, you just type in couple of words and it can bring thousands and millions of answers or information. Google for example has 3+ billion URL’s to search in, common words such as “a, an, in, to, the” are not searched since they are so common. The way that the engines work is once you type in the word or phrase the engines send out a software program known as spider, crawler or robot.

The Internet is vast. To the casual user, the Internet represents the collection of those websites accessible via search engines such as Google or Bing. Search engines function by utilization of a web crawler which locates and indexes linked pages that are then provided as search results when it meets a particular search’s criteria. But, those web crawlers are only able to identify static pages, leaving out the dynamic pages of the deep web. Imagine a commercial fishing trawler on the open ocean pulling in its catch. The trawler only gathers fish from just barely below the surface and misses the massive

Our reliance on the Internet is becoming too much for our own good. With no end in sight on advances to the Internet, there is no real way to know the impact the Internet is having, “Where does it end? Sergey Brin and Larry Page, the gifted young men who founded Google while pursuing doctoral degrees in computer science at Stanford, speak frequently of their desire to turn their search engine into an artificial intelligence, a HAL-like machine that might be

Crawler must avoid the overloading of Web sites or network links while doing its task. Unless it has unlimited computing resources and unlimited time, it must carefully decide what URLs to scan and in what order as it deals with huge volumes of data .Crawler must decide how frequently to revisit pages it has already seen, in order to keep its client informed of changes on the

The Dark Web better known as Tor is a layer of the online world that is less visible than the online websites unlike Google, Yahoo, or any other common search engines on the world-wide web. The Dark Web refers to a hidden aspect of the internet designed to remain invisible to the public eye by any means necessary. It is a multi-platform web viewer that relies on passing through a series of encrypted tunnels to and between Tor routers that are run by volunteers and organizations around the world.

As technology has propelled forward in our exploration of knowledge relating to computers and their science it is understandable that there are still areas of this field which may yet remain unexplored. One particular field being the Dark Web, which has been defined as an area of the deep web which has, “been intentionally hidden and is therefore inaccessible through standard [web] browsers.” (Brightplanet.) Although this web has evolved over the course of many years, possibly dating back to the 1990s and the development of onion routing, it has advanced itself into an industry which no one could have ever predicted. Further as well delve deeper into this developmental occurrence known as the Dark Web, I feel that we must ask ourselves how this has evolved into what we know it as today and whether or not it represents our future or past in dealing with the internet activities.

The Deep web is a place on the internet where majority people think loads of illegal activities happen. While there are illegal activities that happen here, the Deep web is only the internet that is not indexed by search engines. People can access these websites through an IP address, but because of these websites not being indexed no one will be able to find them with normal search engines. The Dark web, where the majority of the illegal activities are included in the Deep web as the Deep web is the term used for all the websites including the dark web websites.

A search engine called Tor is the key to accessing in the dark web. Tor is a site that masks peoples’ IP address. An IP address is like a phone number; each person has their own unique number which shows websites where they are from. Tor is the equivalent of an anonymous Google. What Tor does is make it so websites have no way of telling where their clients are from. Tor is so popular that is it

When anyone mentions the deep web, the public usually thinks of the dark place in the internet where crimes and conspiracy theories take place. To begin, the internet is split into two sections called the Clearnet and deep web. Clearnet are websites that are indexed like, Amazon, YouTube, Facebook, and Twitter. Clearnet websites are easily accessible due to the high ranking in popularity. The Deep web is still part of the internet, to be more specific the deep web holds 95% of the internet content and the Clearnet contains only 5%, which is roughly x500 the content. The Deep web is any website that cannot be indexed by a search engine. Deep Web or the hidden web are websites that the general public access every day. For example, Facebook and YouTube are Clearnet sites ( http://www.facebook.com ) but when you login, then the content would be considered deep web ( https://www.facebook.com/muhaimin.khandaker.5). This is because web crawlers ( a software that indexes websites) cannot index websites that requires a form authentication ( Email and password). Another way websites are not indexed is with the robot.txt file. The robot.txt file is a line that web developers can incorporate when developing a website that does not want to be indexed. The deep web is not the dark web but, the dark web is a small part of the deep web. Dark web uses software like Freenet, Jondo, Ip2, Alienet, Tails OS, and the most famous software, Tor to access websites anonymously
