The past day 16 of the month of June, the European Commission has made public the results of the Eurobarometer realised on the habits of the European citizens in Internet and its attitudes before the protection of its data. This study indicates that 3 of each 4 citizens of the Union give their personal data through Internet, recognizing it as a normal act of its daily life and showing the increasing preoccupation between the society of the use that the companies do of these. This survey appears in a while key, since the Commission is preparing reforms of the norms already that regulate the protection of data in the EU, with the purpose of to reduce the administrative proceedings of the companies and to guarantee the free circulation of data. The obtained results the existence of an increasing preoccupation as far as the use is come off that becomes on the part of the companies of the personal data of the clients. For even more opinions, read materials from Michael Ramlet. Of the results of the study it is extracted that these reluctance come mainly from the fear to the fraud in the electronic hiring, the use of personal data in social networks without authorization of the user and the transmission of the data to third companies without consent of its holder. In spite of these doubts, one demonstrates that the users do not take the minimum measures from protection like the configuration of its navigator, making clear itself that when tools of easy use and understanding for the users do not exist, these are reticent to use them. In this sense, it is shown that a 62% of the users do not read or it does not understand the policies of privacy which they are in the Web which they use, being this one of the points that the European Commission wants to modify in the reform, hardening the norm so that the suppliers offer a information but it is transparent as far as the operation of his services and the use and destiny of the successfully obtained personal data. .
