First of all, you can decide to use an alternative search engine which doesn’t log your activity and it is not possible to define your profile about your web activities.

Privatelee

Privatelee has been developed to offer better privacy to people who prefer not to have their web searches automatically analyzed by google.com.

This search engine can work on https mode and its search results are the mix between external search such as Google and Bing. You can also decide to use just one web engine or both. Comparing the results obtained we can affirm that Privatelee is really very effective and offers the same main features of Google and Bing.

Startpage

Startpage is based on Google and has many flexible features that can be selected using the “settings” page. This particular search engine deletes all the logs after 48 hours and you can anonymously visualize images and videos or define how to manage cookies. Moreover, Startpage allows you to save your settings without using cookies.

As for Privatelee, please be sure to type https and not a ”simple” http when you insert Startpage address in the bar.

Secondly, if you use Firefox, you can use a specific add-on TrackMeNot. TrackMeNot is a simple but useful add-on you can install on Firefox to obfuscate user search data profiler on Google, Bing, Yahoo, Baidu and others. TrackMeNot automatically issues random queries on the main search engines using a list a generic list of words. In this way, search engines are not able to create a real profile about you as web user. Your real searches will be just few between the hundreds fictionally created by TrackMeNot. TrackMeNot is completely configurable: you can choose the query frequency or define the klog of your automatic queries. By default, TrackMeNot uses the words contained in the RSS of four primary websites: The New York Times, CNN, MSNBC and The Register.

Last but not least, if you are using your PC in any area with poor Internet connection, you can disable TrackMe Not with just a click. Easy and fast!

In fact the IPs of free proxies change frequently and sometimes you are obliged to spend a lot of time searching for the right IP of free proxies. Other times the free proxy addresses are so overcrowded that you have to wait many seconds before you can visualize webpages.

One exception is anonymoX, a simple add-on for Firefox which always works properly and assure a good connection speed. AnonymoX has two different service levels, the free basic service has fewer features but it really works properly and it’s fast.

With the free level you can choose your favourite IP exit country between USA, UK and NL. You can also decide if you prefer to stealth your web surfing using anonymoX features or the classic TOR servers. Moreover, you can change your fictional ID every times you want also while you are surfing the web.

During all our tests anonymoX was able to assure us a good surfing privacy, in particular we successfully tried to change browser id and we really appreciated the possibility of visiting .onion websites through the Tor option. Recommended!!!

On Ubuntu you have the possibility to move any file to the Trash but, as we demonstrate in our last post, anyone has the possibility to recover them using a simple, basic GUI, program called PhotoRec.

If you want to be reasonably sure that none will be able to recover a file you decided to permanently delete you have to use the Shred command. Shred is native in Ubuntu Kernel and literally delete your files overwriting them repeatedly with arbitrary data. After you delete a file with Shred you can be sufficiently sure that recovering procedures will not succeed.

As usual we must warn you that technology is rapidly evolving and what could be considered sure today, tomorrow will be out of date! So, if you think you need to preserve your privacy in the best way, don’t forget to change the hard disks regularly and mechanically destroy your old ones. Sincerely we hope our readers haven’t this kind of need.

To start using Shred on Ubuntu you have to open a Terminal and type:

sudo shred –help

In this way you will visualize the grammar and all the possible options offered by this program.

The correct grammar to use Shred is:

shred [OPTIONS] FILE

or, if you want to shred a entire partition:

shred [OPTIONS] /dev/[HDA9]

The possible options are:

  -f, –force    change permissions to allow writing if necessary
-n, –iterations=N  overwrite N times instead of the default (3)
–random-source=FILE  get random bytes from FILE
-s, –size=N   shred this many bytes (suffixes like K, M, G accepted)
-u, –remove   truncate and remove file after overwriting
-v, –verbose  show progress
-x, –exact    do not round file sizes up to the next full block;
this is the default for non-regular files
-z, –zero     add a final overwrite with zeros to hide shredding
–help     display this help and exit
–version  output version information and exit

In our experience, to operate in the fastest way, we decided to add Shred on the Nautilus Menu and have the command ready with a simple right click on the mouse.

For this reason you have to open a Terminal and type:

sudo apt-get install nautilus-actions

Then you launch the program following this path: System->Preference->Nautilus Actions Configuration.

Last, you have to configure Shred filling e.g. the following parameters:

Label: Shred
Tooltip: Shred utility to securely erase files
Icon: gtk-dialog-warning
Path: shred
Parameters: -f -u -v -z %M
Filenames: *
Mimetypes: */*
Appears if selection contains: Both
Be sure to check the box “Appears if selection has multiple files or folders“

To finish your configuration, do not forget to open again a Terminal and type:

nautilus -q
