Abstract

The present invention relates to a method for a secure transaction utilizing a portable radio communication device (10), wherein both parts in the secure transaction are protected against fraudulent actions, among other things by use of a common transaction identity on a predefined transaction server.

Claims

1. A method for a secure transaction utilizing a portable radio communication device, in which a first transaction software in which a transaction server is predefined has been installed, wherein as a part of the installation, a user of the portable radio communication device has been identified in a secure way and tied to said first transaction software in said portable radio communication device, whereby said first transaction software has also been connected to a user account for said predefined transaction server, the method comprising:

initiating, by wireless encrypted communication, said portable radio communication device on said predefined transaction server, where said initiation puts the user, as a first transaction part, in an active transaction state on the predefined transaction server;

initiating a transaction between the first transaction part and a second transaction part using a transaction identity;

initiating the second transaction part, that uses a second transaction software operating independently of said first transaction software, on the predefined transaction server, thereby putting the second transaction part in an active transaction state on the predefined transaction server;

sending information about the transaction connected to the transaction identity from the second transaction part to the predefined transaction server;

the predefined transaction server identifying the first and second transaction parts by the transaction identity, and checking that the first and second transaction parts are in the active transaction state;

finalizing the transaction connected to the transaction identity based on the information about the transaction received by the predefined transaction server; and

sending a transaction receipt of a finalized transaction connected to the transaction identity from the predefined transaction server to the first and second transaction parts.

2. The method according to claim 1, wherein the transaction identity has been predefined and the transaction server and the first transaction part informed thereof before initiation of the transaction.

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

requesting the transaction identity from the transaction server; and

creating the transaction identity in the transaction server.

4. The method according to claim 3, further comprising reusing the transaction identity for another transaction after the transaction receipt has been sent.

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

sending, by wireless encrypted communication, the information of the transaction connected to the transaction identity from the predefined transaction server to the first transaction part;

verifying the transaction connected to the transaction identity at the first transaction part by entering a user verification in the first transaction software; and

sending, by wireless encrypted communication, the verification connected to the transaction identity from the first transaction part to the predefined transaction server.

6. The method according to claim 5, wherein the user verification is a personal identification number, which is entered into the portable radio communication device to verify the transaction.

7. A method for a secure transaction utilizing a portable radio communication device, in which a first transaction software in which a transaction server is predefined has been installed, wherein as a part of the installation, a user of the portable radio communication device has been identified in a secure way and tied to said first transaction software in said portable radio communication device, whereby said first transaction software has also been connected to a user account for said predefined transaction server, the method comprising:

initiating, by wireless encrypted communication, said portable radio communication device on said predefined transaction server, where said initiation puts the user, as a first transaction part, in an active transaction state on the predefined transaction server;

initiating a transaction between the first transaction part and a second transaction part using a transaction identity;

initiating the second transaction part, that uses a second transaction software operating independently of said first transaction software, on the predefined transaction server, thereby putting the second transaction part in an active transaction state on the predefined transaction server;

sending information about the transaction connected to the transaction identity from the second transaction part to the predefined transaction server;

verifying the transaction connected to the transaction identity at the first transaction part by entering a user verification in the first transaction software;

sending, by wireless encrypted communication, the verification connected to the transaction identity from the first transaction part to the predefined transaction server;

the predefined transaction server identifying the first and second transaction parts by the transaction identity, and checking that the first and second transaction parts are in the active transaction state;

finalizing the transaction connected to the transaction identity based on the information about the transaction received by the predefined transaction server; and

sending a transaction receipt of a finalized transaction connected to the transaction identity from the predefined transaction server to the first and second transaction parts.

8. The method according to claim 7, wherein the user verification is a personal identification number, which is entered into the portable radio communication device to verify the transaction.

9. The method according to claim 7, wherein the transaction identity has been predefined and the transaction server and the first transaction part informed thereof before initiation of the transaction.

10. The method according to claim 7, further comprising:

requesting the transaction identity from the transaction server; and

creating the transaction identity in the transaction server.

11. The method according to claim 10, further comprising reusing the transaction identity for another transaction after the transaction receipt has been sent.
