Abstract

A mobile communications device for the display of an incrementally received message includes a message viewer application for scanning the received portions of the message. On determination that the received portion of the message includes a first displayable portion of the message content, the system signals to a message server to halt the message server from forwarding further portions of the message content. The system provides a mechanism for the user of the mobile communications device to cause the mobile communications device to further signal the the message server to recommence the forwarding of further portions of the secure message content to permit the verification of the e-mail based on the further portions of the secure message content.

Claims

1. A method for transmitting a message a server to a mobile communications device, the message content comprising at least one content portion delimited within the message by a predefined identifier, the method comprising the steps of:

a) transmitting a first segment of the message to the mobile communications device, the first segment comprising at least a part of the at least one content portion;

b) receiving a request from the mobile communications device to send the remainder of the at least one content portion;

c) scanning the message for the predefined identifier to identify the entire remainder of the content portion delimited by said predefined indicator; and

d) transmitting the remainder of the content portion to the mobile communications device.

2. The method of claim 1, further comprising the step of determining whether the message content is signed, encrypted, or both signed and encrypted.

3. The method of claim 2, wherein if the message content is encrypted or both signed and encrypted, step c) further comprises the steps of receiving a decryption key from the mobile communications device and decrypting the message content prior to scanning the message for the predefined identifier.

4. The method of claim 1 wherein at least one content portion of the message content comprises content displayable on the mobile communications device.

5. The method of claim 1 further comprising the step of transmitting the entirety of the message to the mobile communications device upon receipt of an instruction from the mobile communications device to transmit the entirety of the message, said step being executable at any time during the method.

6. The method of claim 5 further comprising the steps, at the mobile communications device, of receiving the entirety of the message and verifying the message.

11. A computer program product comprising code operative to carry out the steps of the method of claim 1.

12. A computer program product comprising code operative to carry out the steps of the method of claim 3.

13. The method of claim 3 wherein at least one content portion of the message content comprises content displayable on the mobile communications device.

14. A computer program product comprising code operative to carry out the steps of the method of claim 5.

7. A system for the transmission of a message receivable on a mobile communications device, the message comprising a message content portion displayable on the mobile communications device, the system comprising:

means adapted to transmit a first segment of the message to the mobile communications device, the first segment comprising at least a part of the message content portion displayable on the mobile communications device;

means adapted to receive a request from the mobile communications device to send the remainder of the message content portion displayable on the mobile communications device;

means adapted to scan the message for a predefined identifier to identify the entire remainder of the message content portion displayable on the mobile communications device delimited by said predefined identifier; and

means adapted to transmit the remainder of the message content portion displayable on the mobile communications device to the mobile communications device.

8. The system of claim 7, further comprising means adapted to determine whether the message content portion displayable on the mobile communications device is signed, encrypted, or both signed and encrypted.

9. The system of claim 8, further comprising means adapted to receive a decryption key from the mobile communications device and decrypt the message.

10. The system of claim 7 further comprising means adapted to transmit the entirety of the message to the mobile communications device.
