Now a days you have to be careful to send your mails around the world totally unsigned and unencrypted. Not only the bad terrorists or hackers are reading your mail but also every police on this earth. To be sure that only the authorized person can read the message you can use pgp to encrypt the message. Another advantage is that you can sign the message so that the person who receives it can be sure that this mail is yours and it wasn’t modified.
That means that you can call all of your friends totally free. It doesn’t matter in which country he/she lives, you only have to know the telephone number and nothing more. Another important advantage is that you don’t have to install any software, you can do it direct in your browser (IE, Firefox, etc.).
The principle is very easy, first of all you have to give your own telephone number and the telephone number of your friend. Secondly you press the call button. After that your phone will ring and you have to pick it up. If you don’t answer the phone the call will be ended. When you picked up the phone the connection to you friend will be established and his/her phone will ring.
In the case of your friend is at home you can talk without a guilty conscience about the price.
The whole thing is based on VoIP and because of that it is also possible to configure you VoIP software or hardware to make a call over this VoIP provider.
Now a day every country and every company want to get as much as possible information about you. The causes are different, some of them want to show you the best advertisement, the other one think you are a bad guy and you have to prove that you are a good guy. However this happens every time when you start your computer and connect it to the world wide web. In the last few months you read a lot about undercover online computer searching by the country. In my opinion is a computer a private place of every human being and the police or any body else should’t have the rights to search your whole private live undercover only because you send an email to your friend or you visited the wrong page at the wrong time.
If you are now frightend then you can try different anonymization service. The most of them are really slow and they are still in developing, but the more user the merrier.
First of all I will list some services and later I will describe them in detail.
More details in the future, because up to now I didn’t tested all of them by myself.
