Something Else to Worry About: Web Bugs

Spammers use them all the time, but have you ever heard of web bugs?  Sure, we all know what cookies are, but what about web bugs?  Well, these are a type of spyware that allows a spammer to know when an e-mail he sent was viewed.  They are also used to confirm the validity of the e-mail address.

Advertisers are also using these web bugs to see which sites people are visiting and how often they visit.  By using this information, the advertisers are able to generate reports on Internet users so that related ads can be placed on each particular user’s browser.

Browsers can either accept or reject cookies, but web bugs are a different story.  They are usually formatted as a GIF (Graphic Interchange Format), which is commonly used on the Internet.  This is why a browser will normally accept the web bugs.  Even though it’s a GIF (which people associate with pictures), the web bug will go unnoticed in a spammer’s e-mail.  This is because the image is very small; usually no bigger than 1 X 1 pixel.  The image will also blend into whatever background it’s on; if the background is white, the web bug will be white.  As for advertisers, they are very clever, too.  They can hide a web bug in a site’s logo, so even though it is right in front of you, you will never see it.

If you’ve ever received an e-greeting card, you have encountered web bugs.  When a card is sent, the sender will be given an option to be e-mailed when the card is received and viewed.  This is a prime example of web bugs at work.

Because spammers are one of the main users of web bugs, concerns about privacy are high.  With the use of web bugs, a spammer will have access to an incredible amount of information about the recipients of his e-mails.  The web bugs will tell the spammer the IP Address of the computer receiving the web bug, it identifies the URL the web bug came from, it identifies the URL of the page it was viewed on and it can identify the exact time the web bug was viewed.  These web bugs are like tiny little stalkers, keeping track of your movements.

Privacy concerns also arise when a web bug is placed on a particular website.  The main concern is that an individual’s Internet browsing is being tracked without that individual’s knowledge or consent.  To make matters worse, this tracking isn’t going against any website’s privacy policy since the bugs are generally placed by third parties.  Third parties aren’t required to adhere to the privacy policy terms and conditions.

Whether they come from a spammer’s e-mail or a website, these web bugs are putting everyone’s privacy in jeopardy.  Personal information is being gathered, yet there’s nothing you can do to stop it.  One thing you can do to help guard against the web bugs is to turn off your browser cookies.  A safer option would be to use a proxy server.  With a proxy server, you and your activities can’t be tracked by web bugs because it’s not your IP Address that is being tracked; it’s the IP Address of the proxy server.

You can also keep your privacy secure by using the proxy servers of Privacy Partners.  They offer a FREE trial so that you may see firsthand how using a proxy server can work to your advantage.  Besides changing your IP Address, each connection is encrypted and NEVER monitored, so you can be sure that your information will be safe. 

What Is An IP Address?

Anyone who uses a computer has heard the term “IP Address”, but what exactly does that mean?  What is an IP Address?

 

An IP Address, or Internet Protocol Address, is the digital “address” assigned to every device connected to the Internet. Internet Protocol is the technical standard that should be followed while using the Internet.  This protocol was developed in the 1970s.

There are two versions of IP that support the computer network addressing.  They are:  Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6).  The most commonly used version is IPv4.  With this version, the IP Addresses are four bytes (or 32 bits) long.  IPv6 is the newer version, which allows IP Addresses of 16 bytes (or 128 bits) long.  Whichever version is used, the IP Address has two main purposes:  host or network interface identification and location addressing. 

IPv4 addresses are typically shown in a “dot-decimal” sequence.  They are made up of four parts, using numbers that range from 0 to 255.  Each part is separated by a decimal (or dot) and each group consists of 8 bits.  An example of this is shown below:

The Internet Assigned Numbers Authority (IANA) is responsible for coordinating the global pool of IP Addresses and then providing them to the Regional Internet Registries (RIRs) so they can be assigned to end users, including Internet service providers.  The main address pool used by IANA was depleted on February 3, 2011.  This is the date that the last blocks were assigned to the 5 RIRs.

IPv4 addresses were depleting so rapidly due to the explosive growth of the Internet, that the Internet Engineering Task Force (IETF) was forced to look into new technologies in order to expand the address capacities.  The solution they decided on was to completely redesign the Internet Protocol.   In 1995, IPv6 was named as a means to replace IPv4.

In this new version, the address size was increased to 128 bits from the original 32 bits.  Even considering a growth explosion, this should give a sufficient amount of available addresses well into the future.  A typical IPv6 address would look like this:

This new formula is capable of automatically changing the routing prefix of whole networks without the need to redesign or renumber the system.  This will be necessary if global routing policy changes.
