Abstract

A method for enabling a first party to provide a second party with personalized digital content includes at a network unit: in response to receiving a request from a first party, the request including an identifier identifying a second party, retrieving identity credentials of the second party; and transmitting the identity credentials of the second part to a first party or to a content providing system; and in a content providing system: in response to receiving: a) an identifier from the first party, the identifier identifying digital content in a digital content storage, and b) the identity credentials of the second party, personalizing digital content using the identity credentials, the personalizing adapted to enable the second party to reproduce the digital content but to prevent any unauthorized party to reproduce it; and delivering the personalized digital content to the first party.

Claims

1. A method for enabling a first user using a first terminal to provide a second user using a second terminal with personalized digital content, comprising:

receiving a request at a network unit from the first user via the first terminal, the request comprising a first identifier identifying the second user,

retrieving identity credentials of the second user at the network unit in response to the request;

transmitting the identity credentials of the second user to the first user or to a content providing system;

receiving a second identifier at the content providing system, the second identifier being received from the first user via the first terminal, the identifier identifying digital content in a digital content storage and the identity credentials of the second user;

personalizing the digital content at the content providing system, the digital content being personalized in response to the second identifier using the identity credentials, the digital content being personalized to enable the second user to reproduce the digital content but to prevent any unauthorized user to reproduce it; and

delivering the digital content, as personalized, to the first user at the first terminal;

wherein the first user and the second user are subscribers of a cellular communication network connected to the Internet and the content providing system is adapted to communicate over the Internet.

2. The method according to claim 1, wherein the request is transmitted to the network unit by the first user using a network request.

3. The method according to claim 2, wherein the first user is a device in the cellular communication network.

4. The method according to claim 2, wherein the second user is a device in the cellular communication network.

5. The method according to claim 1, wherein the first user is a device in the cellular communication network.

6. The method according to claim 1, wherein the second user is a device in the cellular communication network.

7. The method according to claim 1, wherein the digital content comprises an encoded piece of music, or an encoded video clip.

8. A system for enabling a first party using a first terminal to provide a second party using a second terminal with personalized digital content, comprising:

a content providing system; and

a network unit to;

receive a request from a first party via the first terminal, the request comprising a first identifier identifying a second party;

retrieve identity credentials of the second party in response to the request; and

transmit the identity credentials of the second party to the first party or to a content providing system, wherein the content providing system;

receives a second identifier from the first party and the identify credentials of the second party, the second identifier identifying digital content in a digital content storage;

personalizes digital content using the identity credentials to enable the second party to reproduce the digital content but to prevent any unauthorized party to reproduce it; and

delivers the digital content, as personalized, to the first party at the first terminal;

wherein the first user is a device in a cellular communication network and the second user is a device in a cellular communication network;

wherein the first user and the second user are subscribers of the cellular communication network connected to the Internet and the content providing system is adapted to communicate over the Internet.

9. The system according to claim 8, wherein the first user has a transmitter to transmit the request to the network unit as a network request.

10. The system according to claim 8, wherein the digital content comprises an encoded piece of music or an encoded video clip.

11. A method for enabling a first user using a first terminal to provide a second user using a second terminal with personalized digital content, comprising:

receiving a request at a network unit from the first user via the first terminal, the request comprising a first identifier identifying the second terminal, retrieving identity credentials of the second terminal at the network unit in response to the request;

transmitting the identity credentials of the second terminal to the first user or to a content providing system;

receiving a second identifier at the content providing system, the second identifier being received from the first user via the first terminal, the identifier identifying digital content in a digital content storage and the identity credentials of the second terminal;

personalizing the digital content at the content providing system, the digital content being personalized in response to the second identifier using the identity credentials, the digital content being personalized to enable the second terminal to reproduce the digital content but to prevent any unauthorized terminal to reproduce it; and

delivering the digital content, as personalized, to the first user at the first terminal;

wherein the first user and the second user are subscribers of a cellular communication network connected to the Internet and the content providing system is adapted to communicate over the Internet.
