Abstract

A system for exchanging digital data between a plurality of users comprises a first computer installation (12) in which said digital data is stored together with at least one determined identity code allocated to each of said items of digital data, and a portable device for sending and receiving digital data (10) for each user for the purpose of receiving the identity codes, each of the portable devices including communications means so as to enable portable devices to exchange the identity codes between each other and transfer them to the first computer installation, said first computer installation then making available to each user of the portable devices the digital data associated with the identity codes as transferred in this way.

Claims

1. A method of exchanging digital data between a plurality of users, each of the users being provided with a portable device for sending and receiving digital data, the method being characterized in that it comprises the following steps:

inputting said digital data for exchanging between users into a first computer installation;

allocating at least one determined identity code to each input item of digital data;

transferring each of the determined identity codes as allocated in this way to the portable device of the user whose digital data associated with said determined identity codes has previously been input into said first computer installation;

establishing connections between the portable devices of different users, over which the devices transmit between each other their at least one determined identity codes;

transferring the determined identity codes received in this way from each of the portable devices to said first computer installation; and

making available to each user of said portable devices the digital data associated with said determined identity codes as transferred in this way.

2. A method according to claim 1, characterized in that said first step of inputting digital data into said first computer installation is performed via a user interface of said computer installation.

3. A method according to claim 2, characterized in that said user interface is selected from one of the following interfaces:

Web;

e-mail;

terminal.

4. A method according to claim 1, characterized in that said second step in which said first computer installation allocates said identity code to said digital data is performed by a random creation process.

5. A method according to claim 1, characterized in that said second step in which said first computer installation allocates said identity code to said digital data is performed from a unique card number entered by the user to said first computer installation.

6. A method according to claim 1, characterized in that said third step of transferring said determined identity code to said portable device is performed via a second computer installation that is local.

7. A method according to claim 1, characterized in that said fourth step of putting two portable devices into communication with each other is performed over a connection of the electrical, magnetic, acoustic, optical, or radio frequency type.

8. A method according to claim 1, characterized in that said fifth step of transferring said determined identity code to said first computer installation is performed via a second computer installation that is local.

9. A method according to claim 6, characterized in that said local second computer installation is connected to said first computer installation via a communications network.

10. A method according to claim 1, characterized in that said sixth step of making said digital data available to users is performed by sending said digital data to an e-mail address of the user.

11. A method according to claim 1, characterized in that said sixth step of making said digital data available to users is performed by consulting said digital data directly at said first computer installation via a communications network.

24. A method according to claim 8, characterized in that said local second computer installation is connected to said first computer installation via a communications network.

12. A method of exchanging digital data between a plurality of users, each of the users being provided with a portable device for sending and receiving digital data, said device having a unique identity number, the method being characterized in that it comprises the following steps:

inputting said digital data that is to be exchanged between users into a first computer installation;

allocating said unique identity numbers to said input items of digital data;

establishing connections between the portable devices of different users whereby the devices transmit to each other their unique identity numbers;

transferring from each of said portable devices to said first computer installation the determined identity numbers that been received in this way; and

making available to each user of said portable devices the digital data associated with the unique identity numbers as transferred in this way.

13. A system for exchanging digital data between a plurality of users, the system being characterized in that it comprises:

a first computer installation in which said digital data for exchanging between said users is stored together with at least one determined identity code allocated to each of said items of digital data;

a portable device for transmitting and receiving digital data carried by each of said plurality of users and having stored therein said determined identity codes;

each of said portable devices having communications means enabling them to exchange between one another said determined identity codes and to transfer to said first computer installation said determined identity codes as received in this way; and

said first computer installation then making available to each user of said portable devices said digital data associated with said determined identity codes as transferred in this way.

14. A system according to claim 13, characterized in that it further comprises a second computer installation that is local for receiving from said portable devices said determined identity codes that are to be transferred to said first computer installation.

15. A system according to claim 14, characterized in that said second computer installation is connected to said first computer installation via a communications network.

16. A system according to claim 13, characterized in that each of said portable devices comprises a first portion for sending and receiving data for transferring said identity codes, a processor portion connected to said first portion for sending and receiving data, a memory connected to said processor portion for storing received identity codes, and a power supply portion connected both to said processor portion and to said memory enabling said portable device to operate without an external power supply.

17. A system according to claim 16, characterized in that each of said portable devices further comprises display means for displaying at least said determined identity codes.

18. A system according to claim 17, characterized in that each of said portable devices further comprises at least one scroll button and an enter button for using said display means to enable said identity codes for transmission to be selected.

19. A system according to claim 16, characterized in that each of said portable devices further comprises a clock circuit enabling determined dates and times to be stored.

20. A system according to claim 16, characterized in that each of said portable devices further comprises sound recording means for recording a commentary and for storing it in said memory in a third storage zone.

21. A system according to claim 16, characterized in that each of said portable devices further comprises visual recording means for recording images storing them in said memory in a fourth storage zone.

22. A system according to claim 16, characterized in that each of said portable devices further comprises a second portion for sending and receiving data in order to transfer said identity codes to said first computer installation via said communications network without passing via said computer installation.

23. A system according to claim 16, characterized in that each of said portable devices further comprises an interface with an external device, in particular to enable annotations to be input.
