The “peer to peer” (P2P) is a technology of downloading and Filesharing between online - Internet - users by the mean of specified software. Since June 1999, the Napster software has made the happiness of millions of individuals who used it to obtain and share free audio files Mp3. Rapidly, the major recording companies have prosecuted the Napster Company and managed to force it to close down. They were arguing against it for it is supporting the development on a large scale traffic of files protected by copyright and thus was threatening the whole music and movies economic world. Since fast Internet connections multiplied, "peer to peer" software and networks improved, so that this mode of exchange became an unprecedented success. Today all cultural products, in particular films and music, are concerned with this free –of– charge distribution without any financial counterpart for the copyright holders. Two tools hold today the top ranks and concentrate large traffic: eDonkey and eMule.

The use of information technology (IT) is exploding. Today, it is in our daily routines to use some kind of information technology. The increase of users increases the number of cyber crimes, ie, crimes that in some way involve IT. As the cyber crimes grow in numbers, the workload for technical investigator increases, these are called digital crime investigators. The thesis is about how police digital crime investigators work and what problems they may encounter during an investigation.

Syftet med detta arbete var att utifrån det teknologiskifte som Internet inneburit och allmänhetens därmed ökade tillgång till musik belysa hur skivbolagens situation förändrats. En fallstudie av två skivbolag baserat på intervjuer genomfördes. Något kortfattat visar studien att ny teknologi skapat nya distributionsvägar, minskat etableringshindren till musikbranschen och minskat skivbolagens kontroll över deras produkter. Piratkopiering kan ses som ett hot mot skivbolagens verksamhet, men kan också fungera som en marknadsföringskanal för dessa. Skivbolag har med rättsliga åtgärder försökt hindra piratkopiering och fildelning, men den strategin kan ses som kortsiktig.

The aim of this study has been to investigate the views concerning the sharing of music files over the Internet as expressed by some of the parties engaged in the current debate in Sweden concerning these issues. The purpose of this study has also been to scrutinize the views about music Filesharing as expressed by the parties in question, as well as the conclusions possible to extrapolate from these opinions. The method used to gather information from the parties subjected to this study has been by conducting and recording interviews with representatives from the organizations and companies entities in question. Those entities are: the Record Company Sony/BMG, The Swedish branch of the organization IFPI International Federation of the Phonographic Industry and the Swedish organization the Pirate Bureau. The method used to analyze the empirically gathered material has been inspired by a method common in the discipline of philosophy of education known as Phenomenography.

The end of the 20th century brought a dramatic change to the music industry. The then predominant models for music consumption and sales were forever altered when the possibility to distribute music over the internet emerged. It has now become evident that it is virtually impossible to stop the distribution of digital music files. Music has turned into a non-excludable and non-rival product, which in economic terms is described as a public good. Public goods theory serves as a starting point for this study, which explores some of the factors that might explain why some consumers pay for music, while others choose to download music illegally.

In the years 1996-2001 the European Union`s copyright-directive was drawn up. This directive led to much lobbying activities from both copyright holders and library organisations like EBLIDA and IFLA. The Internet and Filesharing networks like Napster had led to strong reactions among some copyright holders. Internet gave people an easy opportunity of accessing copyright protected material. Some researchers of copyright have written books where they state that the copyright holders utilize authors fear of illegal copying to strengthen the copyright laws, and by that benefit economical.

The number of wireless networks has increased rapidly among both home users and companies in just a few years. That has brought a lot of good things with it, for example the possibility to connect wireless equipment to the network or Internet from an arbitrary position within range of the accesspoint. But since the transmissions take place through the air some new security risks appear. It?s difficult to restrict the signals to a specific space and thereby a lot easier for unauthorized to eavesdrop or disturb the signals compared to a traditional wired network.
