Method and system for assigning information contents
First Claim
1. A method for assigning information contents which, when a means of transportation is used, are displayed and consumed on a user-specific output unit, comprising:
- assigning an on-board server to each means of transportation, via a first key pair, which includes a first secret key and a first public key, and the first secret key is stored on the on-board server;
before the means of transportation is used, installing an application on the user-specific output unit;
requesting, by the application, a second key pair with a second secret key and a second public key, and the second secret key is transmitted to the application, the second key uniquely assigned to a passenger on the means of transportation, the passenger associated with the user-specific output unit, wherein an identity of the passenger is known to an operator of the means of transportation;
displaying, by the application, available information contents that the passenger desires to consume during an impending use of the mean of transportation, and then a unique identification is created for each selected information content, wherein the passenger is assigned to the unique identification;
requesting, by the application by means of the unique identification, the selected information, and in this process the unique identification is assigned a third key pair with a third secret key and a third public key;
encrypting the third secret key with the first public key and the second public key, and is assigned to the on-board server of the means of transportation;
transmitting the selected information contents to the user-specific output unit outside the means of transportation, encrypted with the third public key; and
establishing a connection between the on-board server and the user-specific output unit within the means of transportation, wherein the on-board server requests the third secret key necessary for decrypting the information contents selected for playback by the user-specific output unit, and decrypts the third secret key.

Abstract
A method and system is provided, including an on-board server, by which, a link to the output unit is set up, and is assigned to a specific conveying means via a first key pair. A first secret key from the first key pair is stored on the on-board server. Before the use of the conveying means, an application is installed on the output unit and a second key pair is requested, a second secret key being transmitted to the application. Then, available information contents are displayed on the output unit, and a unique code is generated for each selected content. The selected contents are requested by the application and the unique code is assigned a third key pair. A third secret key is encrypted with the public keys and assigned to the on-board server. The selected contents, encrypted with a third public key, are then transmitted to the output unit.

13. A system comprising:
-
an on-board server for setting up a connection with a user-specific output unit within a means of transportation; an application, which is installed on the user-specific output unit; a key server and a key database for creation and storage of a plurality of key pairs, each of the plurality of key pairs including a secret key and a public key; a catalog server for requesting an offering of available information contents and for issuing unique identifications for selected information contents; an encryption server for encryption of the selected information contents; an inventory database for storage of assignments between the on-board server, the user-specific output unit, the selected information contents and/or respective associated key pairs of the plurality of key pairs; an information database for storage of available and selectable information contents; and at least one communication network in each case for respective communication outside and inside the means of transportation; wherein the selected information is requested by the application by means of the unique identification, and in this process the unique identification is assigned a third key pair with a third secret key and a third public key; wherein the third secret key is encrypted with the first public key and the second public key, and is assigned to the on-board server of the means of transportation; wherein the on-board server requests the third secret key necessary for decrypting the information contents selected for playback by the user-specific output unit inside and decrypts the secret key necessary for decrypting the selected information contents inside the means of transportation. - View Dependent Claims (14, 15, 16, 17)
