I personally don't use Unity but if you're looking for a way to hide traces of certain, erm, "activities", you could create another user account that was dedicated to that activity which would have its own Unity cache and settings, so you could go wild and nobody ever need know. So let's say you have a passion for painting Warhammer 40,000 characters. ...

One is a Ubuntu GeoIP Provider and the others are scopes. To list what services are connecting to IP addresses try sudo lsof -n -P -i +c 15 Ubuntu GeoIp Provider I don't know what the geoip provider connection is for, what it does, or why we've been told we need it. I can find little information about it, and any attempted explanations about what it is ...

They are proxying through productsearch.ubuntu.com with HTTPS encryption (though there's still a a heated bug discussion over whether the search should be included at all). Unfortunately, while no personally identifying information is sent to Amazon, the privacy policy for Ubuntu sharing information about proxied searches is still unclear. Also, there are ...

As of 2014-02-13, The Tor Project's Ubuntu installation page says: "You'll need to set up our package repository before you can fetch Tor. First, you need to figure out the name of your distribution. A quick command to run is lsb_release -c or cat /etc/debian_version. If in doubt about your Debian version, check the Debian website. For Ubuntu, ask ...

Surf the web anonymously If you just want to browse the web anonymously or access .onion domains (so-called hidden services), the recommended and simplest way is to use the Tor Browser Bundle: Download Tor Browser bundle Extract the downloaded archive click on the file "start-tor-browser". If you need maximum privacy and don't want to leave any trace of ...

This answer was written before you explained that the embarrassing results don't come from a list of recently used local files, but from the References scope. It mainly targets at disabling local files/application history, but also disabling online search results from the Dash. Once you disabled the online results, you won't get those very ugly result ...

What is watching me? Nobody. Without any proof (I did google for it a little bit): I seriously doubt that a webcam can transmit a stream to the outside world before the desktop is active. It would be very complicated to make software to do that and it would require you to install it yourself. And why does this happen? It is the device being ...

This isn't the exact solution you want, but I couldn't find another way to do it more in line with the original question. Chrome The solution is to use incognito mode. To get to incognito mode, use the following keyboard shortcut: Ctrl+Shift+N Firefox The solution is to use private browsing. To start private browsing, use the following keyboard shortcut:...

GeoClue source: wikipedia.org GeoClue is a software framework which can be used to enable geospatial awareness in applications. GeoClue uses the D-Bus inter-process communication mechanism to provide location information1, but there is also a Qt Mobility API in the works2. Through this it aims to simplify development of location aware applications and ...

Another way is to go to "System Settings" > "Privacy" and clean what you need (you can also turn off the "Record Activity"):

A Public folder exists in your Home directory (/home/user) for sharing files with other users. If an other user wants to get access to this Public folder, the execute bit for the world should be set on the Home directory. If you do not need to allow others to access your home folder (other humans or users like www-data for a webserver), you'll be fine with ...

TL;DR: you're safe enough Boot Repair report that you have linked there only lists the layout of your hard drive and bootloader settings. This is quite low level information that reveals nothing useful about you as far as crackers are concerned. The only tiny bit is on line 997, where it shows /home/adam. Users are usually assigned home folders same as ...

Disable the webcam kernel module: modprobe -r uvcvideo uvcvideo is the most common module name. If not found, check lsmod | grep uvcv and you'll get the module name. This will disable it for this session. To make it permanent, add blacklist + module name to /etc/modprobe.d/blacklist.conf. (Like blacklist uvcvideo)

Since any user needs to have a password entry in /etc/passwd the answer is No. Anyone with root access can see the contents of the file and therefore know about your user. Even if you use directory services such as ldap, the user has to be registered somewhere. When it comes to hiding from other desktop users, you can do some things to make it harder. ...

The GUI tools ignore accounts with uid < 1000, which are reserved for system accounts. Give the account an unused uid in that range and it won't show up in the gui tools. Short of patching in a backdoor into the login program though, you can't hide it from the command line tools or direct inspection of /etc/passwd.

Add this line: deb http://deb.torproject.org/torproject.org <DISTRIBUTION> main to the /etc/apt/sources.list file, using sudo nano /etc/apt/sources.list. Also, I find it easier to just download the tor browser bundle and unpack it. You get manual updates, but it informs you when there's a new version.

What does this mean exactly? Your activities are recorded in order to better understand how you are using your system. Using this extensive knowledge, the performance of the system can be improved considerably. For example, knowing which application you launcher when you start your computer would help the system to pre-launch the application in the ...

I do not believe Amazon will see every query in its original state since these queries are sent to productsearch.ubuntu.com and then continue on so your ip address is not reaching Amazon's API. However the other concern is how does Canonical handle these queries since they get them in the original form and have no issued a privacy policy explaining whether ...

Is it used for tracking? No; GeoClue itself does not contact external services for the reason of providing your location, but rather only provides an API for ubuntu applications to use to find out where you are. If you are in doubt that GeoClue is providing location data to a third party for the purpose of surveillance, you can examine the source code ...

Uh, those are not Amazon results but Ubuntu Software Centre results. They are not live online results - but use data obtained by updating the apt database (which you would need to do for installing software anyway). No third party is involved. To disable it, see How to remove the Ubuntu Software Center Suggestions from the Dash.

There is a setting in the Search tab inside All Settings/Privacy called Include online search results. This setting used to be ON by default and this is the setting the articles are referring to. Now it's OFF by default but even if it isn't, you can turn it OFF yourself whenever you like.

Another foolproof solution that wouldn't work for everyone: Open the laptop up, and unplug the webcam. Use an external webcam instead, pluggin it in only as required. I actually did this in the opposite order as the internal webcam was poor quality and I didn't want it on the same angle as the screen.

According to an Ubuntuforms.org staff member, it is to make it easier to share files between new users. You can change the permission to either 700 or 750 if you don't want the files readable and executable by others. Command is: chmod 750 $HOME Note: Ubuntu default is 755

Sometimes, but not usually. Reporting Crashes in System Processes Most of the time when an application crashes or you report a bug manually, you don't have to put in a password for information to be automatically gathered and sent to Launchpad. However, when a program or service that runs as root crashes, collecting data about that crash requires ...

Almost all of the logs are stored in /var/log. Example: /var/log/syslog, /var/log/dmesg, etc.. You could use the Log File Viewer to view them nicely if you want to.

On the installation instruction page of tor you will find what you need to do, here are the instructions. Enter the folloing commands in a terminal of your choice. (ctrl + alt + T as standard) This procedure is the same for every version, but you need to edit the source line with your release name. The currently supported releases are: Ubuntu 13.04 is "...

Omitting the MAC address improves your privacy, but it doesn't "make you anonymous". Every (IPv4 or IPv6) network still has a unique prefix, otherwise you wouldn't be able to receive any packets. In any case, this site shows how to enable the randomized suffix: http://otrs.menandmice.com/otrs/public.pl?Action=PublicFAQ&ItemID=91
