3.  Registered users of Skype are identified by a unique Skype Name, and may be listed in the Skype directory. Skype allows these registered users to communicate through both instant messaging and voice chat. Voice chat allows telephone calls between pairs of users and conference calling, and uses a proprietary audio codec. Skype's text chat client allows group chats, emoticons, storing chat history and editing of previous messages. Offline messages were implemented in a beta of version 5, but removed after a few weeks without notification. The usual features familiar to instant messaging users — user profiles, online status indicators, and so on — are also included.  Skype does not provide the ability to call emergency numbers such as 112 in Europe and 911 in North America. The U.S. Federal Communications Commission (FCC) has ruled that, for the purposes of section 255 of the Telecommunications Act, Skype is not an "interconnected VoIP provider". Features and Services

4.  Skype is claimed to be a secure communication; encryption cannot be disabled, and is invisible to the user. Skype reportedly uses publicly documented, widely trusted encryption techniques: RSA for key negotiation and the Advanced Encryption Standard to encrypt conversations. However, it is impossible to verify that these algorithms are used correctly, completely and at all times as there is no public review possible without a protocol specification and/or the program source code. Skype provides an uncontrolled registration system for users with no proof of identity. Instead, a free choice of nicknames permits users to use the system without revealing their identity to other users. It is trivial to set up an account using any name; the displayed caller's name is no guarantee of authenticity. A third party paper analyzing the security and methodology of Skype was presented at Black Hat Europe 2006. It analyzed Skype and found a number of security issues with the current security model.  13 November 2012, A Russian user published a flaw in Skype security which allowed any non-professional to take over Skype account knowing only victim's email with 7 simple steps. This vulnerability was claimed to exist for months, and existed for more than 12 hours since published widely Security and privacy

6. It's important to know how to deal with unwanted callers on Skype, and how to protect yourself from spam, phishing, and other scams. The first step to safety is adjusting your privacy settings, so only the people you know can contact you.  Blocking Contacts There are several reasons you may want to block someone on Skype. Perhaps the person is sending you spam, or phishing for personal information like your bank account number. On the other hand, you may someday need to block someone you know, for inappropriate behavior like cyber-harassment. You can always block or ignore suspicious contact requests as soon as you receive them. Or you can accept them (for example, if you think you might know the person), then block them later if you change your mind. All you have to do is right-click their name on the Contacts tab, and choose Block This Person from the list of options.  When you block someone on Skype, you can also report them for abuse (spam, phishing, etc.) if the situation warrants it. Safety tips

7.  Instant Message Spam The word spam is often used to refer to junk email, or unwanted email advertisements. Unfortunately, you can receive spam in Skype, too - in the form of instant messages from people you don't know. Phishing scams and malware can even be included in spam, so it's important to know what to do when you receive a suspicious message on Skype. Never reply, or follow any links sent by a spammer. It can be tempting, but it will just confirm to them that you've read the message. They may think you're a good target for more spam - or for scams that are more harmful, because they involve your credit card or personal information. Phishing and other scams Many spammers aren't trying to sell you anything - they're trying to gain access to your information, or even steal money from your bank account. Scams come in many different forms, but they generally work by promising you something that's too good to be true, or by making you think something bad will happen if you don't take action. Phishing is a type of scam where someone pretends to be from a bank or another trusted source, in order to trick you into giving them your personal information. A phishing message will often have a sense of urgency; for example, it may claim that "unauthorized charges" were made on your credit card, and that you need to verify your information.
