Abstract:
1. A method for handling secure message attachments for a mobile device, comprising: receiving at a server a second attachment provided within a secure message, the secure message being enveloped with a secure layer, the secure message itself having been received by the server as a first attachment; providing the secure message without the second attachment to the mobile device over a wireless network; and receiving a request to access the second attachment from the mobile device, wherein in response to the request to access, the method comprises: looking through the secure layer of the secure message using a session key at the server in order to locate within the secure message the second attachment; and rendering a first portion of the second attachment by the server in a format for transmission over the wireless network for viewing the first portion by the mobile device without actually transmitting the second attachment to the mobile device, the format being selected by the server to be compatible for viewing on the mobile device based on characteristics of the mobile device, wherein the request to access the second attachment is automatically provided to the server from the mobile device over the wireless network when either the secure message previously received by the mobile device is opened or when the mobile device receives an indication of a user intent to view the second attachment, and wherein the method further comprises rendering an additional portion of the second attachment by the server in the format for viewing the additional portion by the mobile device in response to an additional request to access the additional portion of the second attachment.
