Surfing the Web Anonymously – Questions to Ask

When you surf the web it is possible to learn information about you even when you don't want to advertise who you are. This is true even if your system contains no virus or malware software. Specifically information that is easily available online includes your IP address, your country (and often more location information based on IP address), what computer system you are on, what browser you use, your browser history, and other information. It gets worse. People can get your computer's name and even find out your name if your machine supports programs like finger or identd. Also, cookies can track your habits as you move from machine to machine.

How do people get this basic information about you?

When you visit another web site, information about you can be retrieved. Basically, information is intercepted and used by others to track your Internet activities.

How do you stop this from happening?

First of all, it is possible to serf the web anonymously and thereby stop leaving a trail for others to find. Note that this is not fool-proof, but it makes it much harder for people to know who you are. There are products called anonymous proxy servers that help protect you. The anonymous proxy server replaces your Internet address for its own. This has the effect of hiding your IP address and making it much harder for people to track you.


How do I get an anonymous proxy server?

There are many vendors who sell anonymous proxy servers. There are also free proxy servers available to you. Two such products are ShadowSurf and Guardster. Guardster (http://www.guardster.com/) offers various services for anonymous and secure access to the web, some paid as well as a free service. ShadowSurf (http://www.shadowsurf.com/) ShadowSurf provides anonymous surfing at their site for free. Go to it and you will find a box to enter a URL that you want no one to track. There are many others, but here are two that are frequently used.

Another interesting product, given the recent news about the Google search engine filtering its findings for the Chinese government, is Anonymizer (http://www.anonymizer.com). This company, among others, recently (Feb 1st, 2006) pressed that it "is developing a new anti-censorship solution that will enable Chinese citizens to safely access the entire Internet filter-free" (http://www.anonymizer.com/consumer/media/press_releases/02012006.html).

Does an anonymous proxy server make you 100% safe?

No. Still, you are much better off if you use such technology.

What other things should I be concerned about when trying to keep my private information private?

Three other items come to mind when trying to keep your information private. First, you can use an encrypted connection to hide your surfing. This article does not go into detail on this, but search the web and you will find a lot of information on this. Secondly, delete cookies after each session. Third, you can configure your browser to remove JavaScript, Java, and active content. This actually leads to limitations, so you need to think about the cost/benefit of this course of action.


Anything else?

Wishing you happy and safe surfing!

Name, Rank and Social Security Number

Identity theft is the fastest growing crime in the U.S. The U.S. Secret Service has estimated that consumers nationwide lose $745 million to identity theft each year. According to the Identity Theft Resource Center, the average victim spends 607 hours and averages $1,000 just to clear their credit records.

Identity thieves employ a variety of methods to gain access to your personal information. They may get information from businesses or other institutions by stealing it; by bribing an employee who has access to records; hacking into records; or conning information out of employees. Once identity thieves have your personal information, they may use it to commit a fraud or theft in your name.

How can you tell if you have become a victim of identity theft? Some signs include unexplained charges or withdrawals from your financial accounts; bills or other mail stop arriving (the thief may have submitted a change of address); a credit application is denied for no apparent reason, or debt collectors begin calling about merchandise or services you didn’t buy.

Your computer can be a goldmine of personal information to an identity thief. To protect yourself and your computer against identity theft consider:

• Updating virus protection software frequently. Consider setting your virus protection software to update automatically. The Windows XP operating system also can be set to check for patches automatically and download them to your computer.
• Not opening files sent to you by strangers, clicking on hyperlinks, or downloading programs from people or companies you don’t know.
• Using a firewall program, especially if you use a high speed Internet connection like cable or DSL that leaves your computer connected to the Internet 24 hours a day.
• Providing your personal or financial information through an organization’s secured website only. While not fool proof, a lock icon on the browser’s status bar or a URL for a website that begins “https:” (the “s” stands for secure), may provide additional security.
• Not storing your financial information on your laptop, unless absolutely necessary.
• Deleting all the personal information stored on a computer before disposing of it. A wipe” utility program to overwrite the entire hard drive is recommended.
• Checking with an anti-fraud education organization such as CardCops (www.cardcops.com). Card Cops runs a web site designed to help consumers determine whether their credit card numbers may have been stolen. They monitor Internet "chat rooms" where identity thieves illicitly trade and sell stolen credit card numbers. CardCops turns the information over to law enforcement authorities, but also allows consumers to access their database to see whether individual card numbers may have been stolen. In the first two months of operation, the site identified more than 100,000 stolen credit cards.

As with any crime, you can not completely control whether you will become a victim, but you can take steps to minimize your risk by remaining diligent and by minimizing outside access to your personal information.

Phishing For Your Identity

Who hasn’t received an email directing them to visit a familiar website where they are being asked to update their personal information? The website needs you to verify or update your passwords, credit card numbers, social security number, or even your bank account number. You recognize the business name as one that you’ve conducted business with in the past. So, you click on the convenient “take me there” link and proceed to provide all the information they have requested. Unfortunately, you find out much later that the website is bogus. It was created with the sole intent to steal your personal information. You, my friend, have just been “phished”.


Phishing (pronounced as “fishing”) is defined as the act of sending an email to a recipient falsely claiming to have an established, legitimate business. The intent of the phisher is to scam the recipient into surrendering their private information, and ultimately steal your identity.

It is not at easy as you think to spot an email phishing for information. At first glance, the email may look like it is from a legitimate company. The "From" field of the e-mail may have the .com address of the company mentioned in the e-mail. The clickable link even appears to take you to the company's website, when in fact, it is a fake website built to replicate the legitimate site.

Many of these people are professional criminals. They have spent a lot of time in creating emails that look authentic. Users need to review all emails requesting personal information carefully. When reviewing your email remember that the "From Field" can be easily changed by the sender. While it may look like it is coming from a .com you do business with, looks can be deceiving. Also keep in mind that the phisher will go all out in trying to make their email look as legitimate as possible. They will even copy logos or images from the official site to use in their emails. Finally, they like to include a clickable link that the recipient can follow to conveniently update their information.
A great way to check the legitimacy of the link is to point at the link with your mouse. Then, look in the bottom left hand screen of your computer. The actual website address to which you are being directed will show up for you to view. It is a very quick and easy way to check if you are being directed to a legitimate site.

Finally, follow the golden rule. Never, ever, click the links within the text of the e-mail, and always delete the e-mail immediately. Once you have deleted the e-mail, empty the trash box in your e-mail accounts as well. If you are truly concerned that you are missing an important notice regarding one of your accounts, then type the full URL address of the website into your browser. At least then you can be confident that you are, in fact, being directed to the true and legitimate website.

Protection You Can Afford

There are numerous ways you can lose the information on your computer. Your child decides to play Chopin on your keyboard, a power surge, lightening, a virus, or even simple equipment failure. Therefore, backing up the contents of your hard drive is an absolute MUST. By regularly making backup copies of your files and storing them in a separate location, you can typically get some, if not all, of your information back in the event your computer crashes.


While a regular backup to floppy, CD, or zip drive will save your files, wouldn’t it be great if you could create an exact copy (a drive image) of your hard disk? That means backups of all your files, programs, and user settings. This would definitely save you time when it came to reloading. Acronis may be able to help.

Acronis True Image 9.0 is a robust disk-imaging utility software that copies the entire contents of your hard drive including data and operating system files, personalized settings, and more, onto another disk or disk partition. Its layout is easy to use and navigate. It also includes wizards which can walk you through both backing up and restoring your computer. Highlighted features include:

• Secure Zone — allows you to save data to a special hidden partition located on your hard drive which would eliminate the need to purchase an extra hard drive.
• PC Cloning — you can upgrade to a new system disk without needing to reinstall the operating system and applications, or configure user settings.
• Acronis Snap Restore - lightening-speed restore of your PC from an image. You can start working in seconds while your system is still being restored.

Acronis provides a free test-drive of its product and a 30-day money back guarantee. When you are ready to purchase, you can either download for $49.99, or if you so desire, order a boxed version for $59.99. With Acronis True Image Home 9.0, you can rest easy that your family pictures, personal documents, tax returns, resumes, and other important information will not be lost forever.

Software Backup For Everyone

Backing up your data with almost any electrical device is crucial to keep things intact. No computer or other electronic device is crash proof, problems can occur at any time. All computers can crash at any given time, which normally results in the loss of all data that was stored on the hard drive.


The potential for less is the ideal reason to create a backup of your software and data. How often or how much you need to backup things however, all depends on how you use your computer. If your data is very important or if you use your computer for work, you may need to create a backup of your software on a daily basis, possibly even hourly for some people.

You can use various devices and equipment to backup your data, such as DVD and CD burners, tapes, external hard drives, servers on the Internet, and so on and so forth. Although each one has pros and cons, you should always use more than one backup method if your data is extremely important to you, just to be on the safe side.

When it comes to backing up your data using software, there are five different methods you can use:
1. Full backup - A full backup will create a mirror of your hard drive, every file and folder that you currently have on your computer.
2. Differential backup - A differential backup creates the backup only for files that have been changed or upgraded.
3. Disk image - This will give you the choice of backing up your entire hard drive or just the files that you select.
4. Unattended backup - Using this method, you can set the software that will create the backup to do all of the work, even if you aren’t around.
5. Snapshot backup - A snapshot backup will mirror your hard drive, backing up the images of your files.

When you decide to get a software program to assist you with backing up your files, you should always get a program that best fits your needs. Price is also an important factor, although ease of use and overall reliability should always be the most important factors when it comes to your data.

Most programs are easy to use, so even if you have never backed up your data before, you’ll be able to do it without any problems. All you’ll need to do is load the software then follow the instructions that come up on the screen.

All in all, software backup is the best way to keep your data preserved and ready. Something can happen to your computer at any given time, which is why you should always be on the safe side and back up your data every chance you get.

Bluetooth Security

These days, all communication technology faces the
issue of privacy and identity theft, with Bluetooth
being no exception. Almost everyone knows that email
services and networks require security. What users
of Bluetooth need to realize is that Bluetooth also
requires security measures as well.

The good news for Bluetooth users is that the
security scares, like most scares, are normally over
dramatized and blown entirely out of proportion. The
truth being told, these issues are easy to manage,
with various measures already in place to provide
security for Bluetooth technology.

It's true that there has been some Bluetooth phones
that have been hacked into. Most devices that are
hacked into are normally those that don't have any
type of security at all.

According to Bluetooth specialists, in order to hack
into a Bluetooth device, the hacker must:
1. Force two paired devices to break their
connection.
2. Steal the packets that are used to
resend the pin.
3. Decode the pin.

Of course, the hacker must also be within range of
the device, and using very expensive developer type
equipment. Most specialists recommend that you
have a longer pin, with 8 digits being recommended.

Fundamentals of security
The "pairing process" is one of the most basic levels
of security for Bluetooth devices. Pairing, is
two or more Bluetooth devices that recognize each
other by the profiles they share - in most cases
they both must enter the same pin.

The core specifications for Bluetooth use an
encryption algorithm, which is completely and entirely
secure. Once the devices pair with each other,
they too become entirely secure.

Until they have successfully paired, the Bluetooth
devices won't communicate with each other. Due to
this pairing process and the fact that it is short
range - Bluetooth technology is considered to be
secure.

As the news has indicated, experienced hackers
have developed ways to get around this level of
basic security. There are ways to get around this
threat, as you can install software to prevent
hackers from getting in.

With Bluetooth becoming more and more popular, it's
really no wonder that security is always in
question. As Bluetooth gets bigger and better,
security will always be something that no one
really takes lightly.

If you've been concerned about Bluetooth security
in the past, rest assured that newer devices will
offer bigger and better security. Preventing
hackers from getting in is something every owner
is concerned about - and the manufacturer's are
very aware.

How Bluetooth Works

Bluetooth devices will normally operate at 2.4 GHZ
in the license free, globally available ISM radio
band. The advantage to this band includes worldwide
availability and compatibility. A disadvantage to
this however, is that the devices must share this
band with other RF emitters. This includes
automobile security systems, other wireless devices,
and other noise sources, such as microwaves.

To overcome this challenge, Bluetooth employs a
fast frequency hopping scheme and therefore uses
shorter packets than other standards within the
ISM band. This scheme helps to make Bluetooth
communication more robust and more secure.

Frequency hopping
Frequency hopping is basically jumping from frequency
to frequency within the ISM radio band. After a
bluetooth device sends or receives a packet, it
and the device (or devices) it's communicating with
hop to another frequency before the next packet is
sent. This scheme offers three advantages:
1. Allows Bluetooth devices to use the
entirety of the available ISM band, while never
transmitting from a fixed frequency for more than a
short period of time. This helps insure that
Bluetooth conforms to the ISM restrictions on the
transmission quantity per frequency.
2. Ensures that any interference won't
last long. Any packet that doesn't arrive safely
to its destination can be resent to the next
frequency.
3. Provides a base level of security as
it's very hard for an eavesdropping device to predict
which frequency the Bluetooth devices will use
next.

The connected devices however, must agree upon the
frequency they will use next. The specification
in Bluetooth ensures this in two ways. First, it
defines a master and slave type relationship between
bluetooth devices. Next, it specifies an algorithm
that uses device specific information when
calculating the frequency hop sequences.

A Bluetooth device that operates in master mode can
communicate with up to seven devices that are set in
slave mode. To each of the slaves, the master
Bluetooth device will send its own unique address
and the value of its own internal clock. The
information sent is then used to calculate the
frequency hop sequences.

Because the master device and each of the slave
devices use the same algorithm with the same initial
input, the connected devices will always arrive
together at the next frequency that they have agreed
upon.

As a replacement for cable technology, it's no
wonder that Bluetooth devices are usually battery
powered, such as wireless mice and battery powered
cell phones. To conserve the power, most devices
operate in low power. This helps to give Bluetooth
devices a range of around 5 - 10 meters.

This range is far enough for wireless communication
but close enough to avoid drawing too much power
from the power source of the device.
