Nested Email Addressing for Secure High-Resolution Color Fax Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fax technologies are limited by low resolution, lack of color support, and inefficiencies in secure document delivery, storage, and access, failing to seamlessly integrate traditional fax systems with high-resolution, color fax capabilities and secure document processing through nested email addressing.
Innovation Solution
A secure file transfer system that enables high-resolution, color faxing by translating native documents into image format, providing secure upload, storage, and notification, with automatic printing capabilities, and integrates with existing fax setups through a Biscom Document Router (BDR) for seamless transition from traditional to high-resolution, color faxing, utilizing nested email addressing for extended functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fax protocols (T.30/T.38) are used, then reliability and security are improved, but manufacturing precision and measurement precision deteriorate due to low resolution (up to 600 dpi) and black-and-white only format
Solution Approach 1:
The patent merges traditional fax reliability mechanisms (delivery confirmation, security protocols) with modern high-resolution document delivery capabilities. The system combines the trust model of traditional faxing with email-like flexibility and high-resolution image formats, allowing documents to be transmitted with both enhanced quality and maintained security through digital signatures and delivery receipts.
Solution Approach 2:
The system creates a universal document delivery platform that can handle both traditional fax requirements and modern high-resolution document needs. It supports multiple formats (color images, high-resolution scans), multiple delivery methods (email, web portal, direct fax), and multiple authentication levels, making it adaptable to various precision requirements while maintaining core fax reliability.
2Reliability
If traditional faxing is used, then security is improved, but ease of operation deteriorates due to non-instantaneous delivery and extensive error correction requirements
Solution Approach 1:
The patent introduces a document delivery service as an intermediary between sender and receiver. This mediator handles error correction, retry logic, and delivery confirmation automatically, shielding users from technical complexities. The service acts as a buffer that maintains security protocols while enabling instant or near-instantaneous delivery through asynchronous processing and notification systems.
Solution Approach 2:
The system implements self-service mechanisms where the document delivery service automatically handles error correction, retry attempts, and delivery confirmation without requiring user intervention. Users simply send documents through the system, and the service autonomously manages transmission issues, making the process as easy as sending an email while maintaining fax-level security and reliability.
3Adaptability or versatility
If nested email addressing is implemented, then adaptability is improved, but device complexity increases due to control token processing requirements
Solution Approach 1:
The patent extracts the complexity of nested email addressing and control token processing from the end-user system and concentrates it in the document delivery service. Users can specify delivery options through simple email addresses or control tokens in the recipient field, while the service handles the complex parsing, routing, and processing logic. This extraction allows high adaptability without requiring complex processing capabilities in client devices.
Data Source
AI summary
Nested email delivery substitutes a control token into an recipient email address, and uses the result as the username in email to a domain of a secure processing server. At the secure processing server, the recipient email address is extracted, control token identified, and any attachments processed and delivered based on the control token. The secure processing server may be an internet-based secure fax server and attachments processed as native documents for high-resolution, color faxing. Delivery may also be via certified email, or native documents may be processed into workspace storage or through other configured processing. Multiple tokens may be combined to trigger multiple actions.
