Secure Message Attachment Extraction via Server Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless mobile communication devices face difficulties in accessing attachments of secure messages due to the structural security schemes that treat messages as attachments, limiting efficient retrieval and viewing of encrypted content.
Innovation Solution
A method and system where a server processes secure messages to locate and provide attachments to mobile devices, utilizing a secure message processing module to decrypt and render attachments for viewing, even when messages are encrypted or signed with digital signatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secure messages are structured with security schemes that treat messages as attachments, then security and encryption are maintained, but accessibility and ease of viewing attachments on mobile devices deteriorate
Solution Approach 1:
The patent introduces a server as an intermediary between the secure message storage and mobile devices. The server receives secure messages, processes them to extract attachments, and delivers them to mobile devices. This intermediary resolves the contradiction by maintaining security during storage and transmission while enabling easy access on mobile devices, as the server handles the complex security processing centrally rather than requiring mobile devices to directly process encrypted messages.
2Reliability
If secure messages are encrypted and structured as attachments, then data protection is improved, but processing complexity and time to locate and retrieve attachments increase
Solution Approach 1:
The patent applies preliminary action by having the server process and extract attachments from secure messages in advance, before mobile devices need to access them. The server receives the encrypted secure message, processes it to locate and extract the attachment, and prepares it for delivery. This preliminary processing on the server side reduces the time mobile devices would otherwise need to spend on complex decryption and extraction operations.
3Reliability
If mobile devices directly process encrypted secure messages to access attachments, then security is maintained, but device complexity and processing requirements increase
Solution Approach 1:
The server acts as an intermediary that handles the complex processing of encrypted secure messages. Instead of mobile devices directly processing encryption and extracting attachments, the server performs these operations centrally. The mobile device only needs to communicate with the server and receive the extracted attachment, significantly reducing device complexity while maintaining security through the server's processing.
Data Source
AI summary
Methods and systems for handling attachments on wireless mobile communication devices. An attachment provided with a secure message is received at a message server. The secure message itself was received by the server as an attachment. The secure message is processed in order to locate within the secure message the requested attachment. The located attachment is provided to a mobile device.
