Enhanced PDF Generation for Fax-to-Email Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fax-to-email services limit integration and flexibility by only sending and receiving fax documents in tagged-image file format (TIFF), which lacks text, font, and format information, and converts images into PDF files that are devoid of additional metadata.
Innovation Solution
A system and method that converts facsimile and email messages into enhanced portable document format (EPDF) files, which include searchable text, password protection, and metadata, allowing for additional information such as signatures and repositionable notes, and can be sent via email or fax, based on user profiles and preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional fax-to-email services send and receive fax documents in TIFF format and convert to basic PDF, then the fax transmission function is maintained, but the documents lack searchable text, metadata, and enhanced functionality
Solution Approach 1:
The patent changes the output format parameter from conventional PDF to EPDF (Enhanced Portable Document Format), which supports additional parameters such as searchable text layers, metadata fields, digital signatures, and form fields. This parameter change enables the system to preserve and enhance information content while maintaining compatibility with existing PDF readers.
Solution Approach 2:
The patent creates a composite document structure by combining multiple elements within the EPDF format: the original image data, overlaid searchable text layers, metadata fields, digital signatures, and form elements. This composite structure allows the document to function both as a visual representation and as a searchable, editable text document with enhanced capabilities.
2Adaptability or versatility
If the system converts fax to basic PDF format, then compatibility with existing systems is maintained, but integration and flexibility are limited
Solution Approach 1:
The EPDF format serves multiple functions simultaneously: it maintains the visual display characteristics of traditional PDF for broad compatibility, while also enabling searchable text, metadata storage, digital signatures, and form filling capabilities. This multi-functionality allows the same document format to satisfy both legacy system requirements and modern enhancement needs.
Solution Approach 2:
The patent introduces the EPDF format as an intermediary between conventional fax/TIFF systems and modern electronic document requirements. The EPDF acts as a translation layer that preserves compatibility with existing PDF infrastructure while bridging to enhanced functionality needed for modern fax-to-email integration, including searchable text and metadata.
3Loss of information
If the system adds enhanced functionality to fax documents, then information richness is improved, but processing complexity increases
Solution Approach 1:
The patent performs preliminary actions during the fax-to-EPDF conversion process by automatically extracting text from the fax image, generating searchable text layers, and populating metadata fields before the document is finalized. This preliminary processing ensures that all enhanced features are prepared in advance, reducing the need for complex post-processing operations.
Data Source
AI summary
A method for converting a facsimile includes receiving the facsimile via the public-switched telephone network, generating an enhanced portable document format (EPDF) file that includes information in addition to image information and communicating the EPDF file to an e-mail server. The EPDF file can then be communicated as an attachment to an e-mail message addressed to the intended recipient of the facsimile. A facsimile processing system includes a public-switched telephone network interface, a packet-switched network interface, a mail transfer protocol server, an input agent, a job processor and a translator. The input agent identifies and forwards the incoming facsimile to the job processor. The job processor determines when an EPDF file is desired and communicates appropriate instructions to the translator. The translator generates the EPDF file in response to the instructions and the image information from the facsimile. The translator integrates signatures and repositionable notes in outbound facsimiles.
