Incremental Secure Message Display on Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices experience slow performance when processing secure messages in formats like S/MIME, due to receiving and processing non-displayable or repetitive data, which can lead to delayed message display.
Innovation Solution
A system and method for incrementally receiving and displaying secure messages on mobile devices, where a message viewer application scans for predefined indicators to halt further message content forwarding once a displayable portion is received, allowing users to verify messages without unnecessary data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire secure message is received for verification, then message security verification is ensured, but message display time is delayed
Solution Approach 1:
The patent divides the message reception process into segments: first receiving and displaying the message header and body portion, then separately receiving the signature portion. This allows the displayable content to be shown to the user immediately while the verification of the signature portion proceeds in the background, thus resolving the contradiction between complete verification and fast display.
Solution Approach 2:
The patent performs preliminary actions by receiving and displaying the message header and body before the signature verification is complete. The user can view the message content immediately, and the signature verification is carried out subsequently without blocking the initial display, thereby reducing perceived message delivery time while maintaining security verification.
2Reliability
If repetitive message content in multiple formats is received, then complete message verification is enabled, but data processing load increases
Solution Approach 1:
The patent extracts only the essential signature portion from the complete message for verification purposes, while the repetitive message body content in multiple formats is not fully received or processed. The message viewer application selectively receives only the necessary components (header, body, signature) rather than all repeated versions, reducing data processing load while maintaining verification capability.
3Reliability
If the message server sends complete message content, then message verification is complete, but network bandwidth is wasted
Solution Approach 1:
The message server sends only the essential portions of the message (header, body, and signature) rather than complete repetitive content. The patent extracts and transmits only the necessary data elements required for message display and verification, eliminating redundant transmissions and optimizing network bandwidth utilization.
Solution Approach 2:
The message transmission is segmented into essential components only. Instead of sending the complete message with all repeated formats, the server transmits segmented portions (header, body, signature) that are sufficient for verification and display, reducing network bandwidth consumption while maintaining message integrity.

AI summary
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 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.
