Abstract

A method and a system are disclosed, of enabling a user of an Internet application to access protected information. An idea behind at least one embodiment of the invention is that a user identifier token is created, after a user has been authenticated by way of a logon mechanism of the Internet application. The user identifier token is then associated with the authenticated user and stored at an Internet client of the authenticated user. When protected information is to be made available for a requesting user, the concerned set of protected information is associated with the authenticated user and an information identifier token is created and associated with the protected information. The information identifier token is delivered to the authenticated user via e-mail. When a request is received from a requesting user, it is verified that the request comprises a user identifier token and an information identifier token, that there exists an association between these tokens and the previously authenticated user and the protected information, respectively, and that the requested protected information is associated with the authenticated user. If so, the requesting user is allowed to access the protected information.

Claims

1. A method of enabling a user of an Internet application access to protected information, said method comprising:

creating user identifier token after authentication of the user by way of a logon mechanism of the Internet application;

associating said user identifier token with the authenticated user;

storing said user identifier token at an Internet client of the authenticated user, the user identifier token not giving access to the Internet application;

associating the protected information with the authenticated user;

creating an information identifier token, the information identifier token not giving access to said Internet application, neither by itself nor in combination with the user identifier token;

associating the information identifier token with the protected information;

delivering the information identifier token to the authenticated user via e-mail;

receiving a request from a requesting user to access the protected information; and

verifying that the request comprises a user identifier token and an information identifier token, and that the user identifier token of the request is associated with the authenticated user, that the authenticated user is associated with the requested protected information and that the requested protected information is associated with the information identifier token of the request, allowing the requesting user to access said protected information.

2. The method according to claim 1, further comprising:

providing the protected information with a digital signature.

3. The method according to claim 1, further comprising:

creating a hash value for the protected information and giving a requesting user access to the hash value on successful verification.

4. The method according to claim 1, further comprising:

encrypting the hash value to provide confidentiality.

5. The method according to claim 1, further comprising:

establishing a secure channel for delivery of the protected information.

6. The method according to claim 1, wherein the information identifier token is delivered through a mail with a web link to the protected information.

7. The method according to claim 6, wherein the information identifier token is a code comprised in the web link.

8. The method according to claim 1, wherein said request to access protected information is received over the Internet.

9. The method according to claim 6, wherein the request to access the protected information is made by using the link at the client.

10. The method according to claim 1, wherein the user identifier token is a cookie.

11. The method according to claim 1, wherein the association between the authenticated user and the user identifier token is made effective by an association between a user identifier and a code comprised in the user identifier token.

12. The method according to claim 1, wherein the association between the authenticated user and the protected information is made effective by an association between a user identifier and an identification of an electronic document.

13. The method according to claim 1, wherein the association between the protected information and the information identifier token is made effective by an association between an identification of an electronic document and a code comprised in the information identifier token.

14. The method according to claim 1, wherein said associations are created by using a database.

15. The method according to claim 1, wherein the user identifier token is arranged such that its content cannot be derived from knowledge about at least one of a provider of the protected information and the authenticated user.

16. The method according to claim 13, wherein the information identifier token is arranged such a that its content cannot be derived from knowledge about at least one of a provider of the protected information, the authenticated user and the electronic document.

17. The method according to claim 1, further comprising:

receiving, from a user of the Internet application, a request to receive documents electronically, whereupon the protected information is sent to an authenticated user electronically.

18. The method according to claim 1, wherein the creating of the user identifier token is performed during a session when the authenticated user is logged on to the Internet application, and wherein the user identifier token is delivered to the client via the Internet.

19. The method according to claim 1, wherein said Internet application is arranged such that the logon mechanism gives the user authorization to use a set of functions during a session with the Internet application.

20. The method according to claim 1 wherein the verification of the request from a requesting user further comprise:

requesting the user to logon to the Internet applications, if the request is found not to comprise a user identifier token, but it is verified that the requested protected information is associated with the information identifier token; and

creating a user identifier token and storing the token at the Internet client the user is currently using if the Internet application user after logon is verified to be associated with said requested protected information, the user identifier token not giving access to the Internet application, neither by itself nor in combination with said information identifier token.

41. A computer program product comprising computer executable components for causing a device to perform the method of claim 1 when the computer-executable components are run on a processing unit included in the device.

21. A device for enabling a user of an Internet application to access protected information, said device comprising:

means for creating a user identifier token after having authenticated the user by a logon mechanism of the Internet application;

means for associating the user identifier token with the authenticated user;

means for delivering the user identifier token to an Internet client of the authenticated user, the user identifier token not giving access to the Internet application;

means for associating the protected information with the authenticated user;

means for creating an information identifier token, the information identifier token not giving access to said Internet application, neither by itself nor in combination with the user identifier token;

means for associating the information identifier token with the protected information;

means for delivering the information identifier token to the authenticated user via e-mail;

means for receiving a request from a requesting user to access the protected information; and

means for verifying that the request comprises a user identifier token and an information identifier token, and that the user identifier token of the request is associated with the authenticated user, that the authenticated user is associated with the requested protected information and that the requested protected information is associated with

the information identifier token of the request, allowing the requesting user to access the protected information.

22. The device according to claim 21, further comprising:

means for providing the protected information with a digital signature.

23. The device according to claim 21, further comprising:

means for creating a hash value for the protected information and giving a requesting user access to the hash value on successful verification.
