Abstract

A method is provided for transmitting information from a user to a first network entity over a communications network. The user enters information into a browser executed at a user terminal. The browser generates a first message comprising the information using a first communication protocol for dispatch over the network via a network port, the first message including an identifier of the first network entity. A client executed at the user terminal receives the first message before the first message reaches the network port. The first message is wrapped in a second message of a second communication protocol used for transmitting messages between the client and a second network entity. The second message is transmitted to the second network entity over the communications network. The first message is unwrapped from the second message at the second network entity, the identifier of the first network entity translated to a network address of the first network entity and the first message is transmitted to the first network entity over the communications network.

wrapping the first message in a second message of a second communication protocol used for transmitting messages between the client and a second network entity;

transmitting the second message to the second network entity over the communications network; and

unwrapping the first message from the second message at the second network entity, translating the identifier of the first network entity to a network address of the first network entity and transmitting the first message to the first network entity over the communications network.

2. A method according to claim 1, further comprising the step of encrypting the information in the first message after receiving the first message at the client.

3. A method according to claim 2, further comprising the step of receiving the first message transmitted by the second network entity at the first network entity.

4. A method according to claim 3, further comprising the step of decrypting the information in the first message, after it is received at the first network entity.

5. A method according to claim 2, wherein the step of encrypting is performed using an encryption key provided by the first network entity.

6. A method according to claim 5, further comprising the step of the first network entity periodically transmitting the encryption key to the second network entity.

7. A method according to claim 1, further comprising the steps of:

transmitting a third message to the second network entity from the first network entity, responsive to receiving the first message;

receiving the third message at the second network entity and, responsive thereto, fetching a webpage from a server;

wrapping the webpage in a fourth message of the second communication protocol;

transmitting the fourth message to the client over the communications network;

unwrapping the webpage from the fourth message at the client and passing the webpage to the browser; and

displaying the webpage to the user in the browser.

8. A method according to claim 7, wherein the third message is a redirect message.

9. A method according to claim 1, wherein the step of wrapping the first message in a second message of a second communication protocol comprises the step of adding a header and a footer to the first message.

10. A method according to claim 1, wherein the first communication protocol is a hypertext transfer protocol.

11. A method according to claim 1, wherein the first network entity is a payment service provider.

12. A method according to claim 1, wherein the communications network is the Internet.
