4. The method as claimed in claim 2, further comprising the protective server supplying on request, instead of the access provider, an address of a host site identified by a name, in correspondence with this name, by means of a domain name system.

5. The method as claimed in claim 1, further comprising modifying a part, comprising information on the identity of the client terminal, of a request formulated from the client terminal intended for a host site before traveling to the host site for which the request is intended.

6. The method as claimed in claim 1, further comprising filtering cookies originating from the network by the protective server and storing, at the protective server, at least a part of the cookies.

7. The method as claimed in claim 1, further comprising an electronic mail server supplying at least one disposable electronic mail address.

8. The method as claimed in claim 7, further comprising monitoring the use of the disposable address by a third party to whom that electronic mail address has been sent.

9. The method as claimed in claim 1, further comprising allocating a plurality of electronic mail accounts to a user, with a unique portal, independent of the client terminal and personal for managing these accounts.

10. The method as claimed in claim 1, further comprising associating a trust status with a host sites, according to knowledge, stored in a knowledge base, on at least the policy of protection of the personal data by a third party operating this host site.

11. The method as claimed in claim 10, further comprising automatically implementing a form for the input of information on the user, supplied by a host site and intended for recording the information input, by the host site, by the protective server according to the trust status, before being submitted for the user'"'"'s approval.

12. The method as claimed in claim 11, automatically performing the approval by the user according to a protection profile that the user has predefined.

13. The method as claimed in claim 1, further comprising representing the user of the client terminal, with respect to the network, by at least one avatar.

14. The method as claimed in claim 13, further comprising storing an information profile comprising the preferences profile and associated with the actual identity of the user or with each avatar in a knowledge base, the information profile being determined, at least in part, by the behavior of the user when the user communicates with the network using the avatar.

15. The method as claimed in claim 14, further comprising modifying the information profile by the user via a configuration server.

16. The method as claimed in claim 13, characterized in that an authorization of use, by a third party operating a host site, of the information attached to the user'"'"'s actual identity or to the avatar by which the user accesses this host site is governed by the user, by the selection and activation of a predefined protection profile.

17. The method as claimed in claim 16, further comprising:

associating a trust status with a host site, according to knowledge, stored in a knowledge base, on at least the policy of protection of the personal data by a third party operating this host site, and

comparing the protection profile with the trust status to define an automatic processing of the data exchanged between this host site and the client terminal, when the user wants to set up a communication with a host site and prior to that communication, and when a host site wants to enter into communication with the client terminal.

18. The method as claimed in claim 17, further comprising:

filtering cookies originating from the network by the protective server and a storing, at the protective server, at least a part of these cookies,

wherein the automatic processing of the data exchanged between the host site and the client terminal comprises the filtering of cookies originating from the network and the storing, at the protective server, of at least part of the filtered cookies.

32. A computer program loadable into a memory, associated with a processor, and comprising portions of codes for the implementation of a method as claimed in claim 1, when the said program is executed.

34. A data medium on which is recorded a computer program as claimed in claim 32.

35. A method of downloading a computer program as claimed in claim 32.

19. A protective server set to form the interface between a client terminal and a network of host sites and enable a user of the client terminal to control the broadcasting of information concerning the user, on the network, the protective server set comprising:

means, at a protective server, for masking the identifier of the client terminal, with respect to the network,

means for protecting at least part of the data from being read by any person not authorized to read this part of the data, when the data is communicated between the protective server and the client terminal,

comparison means for comparing, with knowledge on at least one host site, a preferences profile categorizing the user and approved by the latter, and

means for controlling, according to information generated by the comparison means, the exchange of data between the client terminal and this host site.

20. The protective server set as claimed in claim 19, further comprising means for creating at least one avatar by which to represent the user with respect to the network.

21. The protective server set as claimed in claim 19, further comprising means for managing an information profile based on personal data and on the communications it sets up with the network.

22. The protective server set as claimed in claim 19, further comprising means for protecting at least a part of the data exchanged between the protective server and the client terminal from being read by a network access provider.
