Many web sites implement various techniques to prevent web scrapers from extracting web data from their web sites. The most popular protection techniques are CAPTCHA and IP banning.
CAPTCHA protected web sites displays a word as an image and requires the user to enter the word he sees in order to proceed. It is impossible for web scraping software to bypass a CAPTCHA screen, because the web scraper is unable to extract the word from the image. OCR technology can be used to recognise words in an image, but most CAPCHA images include noise which makes it impossible to consistently recognise the words using OCR.
Visual Web Ripper is an advanced web grabber tool that features semi-automatic processing of CAPCHA protected web sites. Visual Web Ripper can recognise CAPTCHA screens while extracting data and display the CACHA image in a Window. Once the user enters the CAPTCHA word in the form, Visual Web Ripper will automatically enter the word on the website and continue extracting web data. CAPTCHA is normally only used in a few places on a website in order not to annoy ordinary users, so the operator of the web scraping software normally only need to enter a CAPTCHA word a few times for each web scraping session.
If you are extracting large quantities of data from a web site, the web site may recognise your IP-address and ban the IP-address from the website. This means you will no longer be able to visit the web site, or extract data from the web site.
Instead of using your own IP-address to access the web site, you can access the website through a proxy-server, so the web site sees the proxy-server’s IP-address instead of yours. The Visual Web Ripper web scraping software allows you to enter a list of proxy-servers and will automatically cycle through the proxy-servers, so the target website doesn’t see one single IP-address extracting lots of web data.
Another benefit of using a proxy-server is that the target website will never be able to recognise you by looking up the owner of you IP-address.
Most free proxy-servers are quite unreliable, and if you are unwilling to pay for stable proxy-servers, you may want to take a look at the free TOR network. TOR is a network of proxies, so your web request will go through multiple proxy-servers before ending up on the target web server. This is obviously a very secure and private way of scraping the web, but it does reduce the web data extraction speed. The Visual Web Ripper web scraping software works well with the TOR network.

What is a bit?
A bit is the smallest unit of data that can be used. It is a binary digit ( BI nary D Igit). There can be only 0 or 1. Nothing else … So if you write Veur 0, written in binary 0 … And if you want to write one, write in binary, 1.
But if you wanted to write 2? We’re bored … Well no, not that much. 2 is the figure immediately above one which is written with a 1 or 0. So 2 neu can not be written 2 or 3 or 4 or 5, or 6 or 7 or 8 or 9 … But 10! Yes, 10 is the smallest number greater than 1 which contains only 0 or 1.
So we have: 0 = 0
1 = 1 2 = 10
and 3? how do we write? Well, 3, in binary, is the number immediately above 10, which is written with 1s and 0s. So: 11 3 = 11 Cons by 4 … Can not be 12 or 13 or 20, or 30, not 50 or 80 … but 100, which is immediately above the figure 11, which contains only 1 and 0.
4 = 100 And so on:
5 = 101 6 = 110
7 = 111 etc..
And this is how we consider the memory required to operate a computer: For bits. In fact, the memory may contain a number of BITS. And each digit requires a number of different bits. For example, 6 (110) need 3 bits to be written, whereas 2 (10) needs only two bits (1 and 0) to be written. Go a little exercise to conclude: How many bits are they required to write (it is said to code):
– 12-bit needs _____ – 23-bit needs _____
– 32-bit needs _____ And when you’ve created your short list of binary digits from 1 to 32, look at this little feature:
32 in binary is written: ____________ (And 32 divided by 2 = 16)
16 in binary is written: ___________ (And 16 divided by 2 = 8)
8 in binary is written: ___________ (And 8 divided by 2 = 4) 4 in binary is written: ___________
8 in binary is written: ___________ (And 4 divided by 2 = 2)
2 in binary is written: ___________ (And 2 divided by 2 = 1)
1 written in binary: ___________ And so, without having to calculate it, you should be able to write in binary by simple deduction:
64: ________ 128: ___________
256: ____________ (How strange: That is the number of available columns in Excel …) and 512: ____________

Confidential information can be found in offices and homes. This confidential information can become dangerous when falling into the wrong hands. Businesses need to be extremely careful when handling other peoples details. If businesses loose confidential information, they will find themselves in a lot of trouble, especially if peoples personal details are put at risk or identity theft, or even worse peoples lives are at risk. There are plenty of data destruction or removal techniques out there to ensure data is erased, when no longer needed by a business. Data destruction is a very strong technique, often used to destroy secure data.
Data destruction is a way in which companies can destroy any information which is confidential. There are a number of data destruction techniques which can be used. However some methods are more reliable than other techniques. It is highly important that businesses who store details which are personal, such as names and addresses, delete the data or remove of it, when it is no longer needed. The government is particularly at risk if their data is uncovered, as it could lead many people to be at risk of harm and many people will often loose their jobs. Data destruction is a very important technique for many and methods like this should be used in every business storing personal details, or highly confidential information.
Data Destruction Methods
There are a number of data destruction methods which can be used. Data destruction methods are strong, however some are stronger than others. Crushing is one data destruction technique. Crushing causes physical damage to computers, software and magnetic media storage devices, this prevents them from being able to be used again. This meaning secure data cannot physically be accessed. Melting is another technique available, which causes computers to become disfigured, which prevents data recovery. Another technique is drilling, which is similar to the other two, as physical destruction is caused. These techniques are all very good, however one disadvantage of this method is the fact the equipment that has become damaged, cannot be re-used. Data sanitization is another method which does not require the physical damage, which means computers can be re-used.
Confidential Data Destruction
It is very easy for confidential information to enter third party hands, if secure data destruction techniques are not used. There are many people out there, who look to recover sensitive data to steal identity, if the data is highly sensitive it can lead to peoples lives being put at risk. This is what makes it so important to remove all sensitive data as people have had their lives ruined through identity theft
Predictive Analytics is the process of dealing with variety of data and apply various mathematical formulas to discover the best decision for a given situation. Predictive analytics gives your company a competitive edge and can be used to improve ROI substantially. It is the decision science that removes guesswork out of the decision-making process and applies proven scientific guidelines to find right solution in the shortest time possible.
Predictive analytics can be helpful in answering questions like:
Who are most likely to respond to your offer?
Who are most likely to ignore?
Who are most likely to discontinue your service?
How much a consumer will spend on your product?
