Electronic Device File Attachment via Image Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method to securely manage and view file attachments in electronic devices, particularly in portable devices used for official business, where sensitive materials may inadvertently be disclosed due to restricted access and limited functionality when accessing company email servers from outside.
Innovation Solution
An electronic device method and apparatus that attaches files to an application program, generates an image corresponding to the file, and inserts this image into the email body, allowing for secure file management and viewing, including determining the number and quality of images and executing application programs in the background to support file attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If files are attached to emails in portable electronic devices, then file transmission capability is improved, but security risk increases due to potential inadvertent disclosure of sensitive materials
Solution Approach 1:
The patent segments the file handling process into distinct components: file attachment, image generation, and image insertion. By converting files to images and inserting them into the email body, the system separates the viewing function from the original file, allowing security control while maintaining usability.
Solution Approach 2:
The patent creates an image copy of the attached file and inserts this copy into the email body. This copying approach allows users to view file contents as images without directly accessing the original sensitive files, thereby reducing security risks while maintaining file transmission capability.
2Reliability
If access to company email servers is restricted from outside, then security is improved, but functionality deteriorates as users cannot check or reply to emails effectively
Solution Approach 1:
The patent introduces an image generation mechanism as an intermediary between the email client and attached files. This intermediary converts files to images that can be displayed within the email interface, enabling users to view file contents without direct access to the email server or original files, thus maintaining security while improving functionality.
3Ease of operation
If users can view attached files directly, then ease of operation is improved, but security control is weakened due to unrestricted access to sensitive materials
Solution Approach 1:
The patent creates image copies of attached files and inserts them into the email body. Users can view these image copies directly in the email interface, maintaining ease of operation. However, since these are generated images rather than direct file accesses, security control is preserved as users cannot access the original sensitive files through this mechanism.

AI summary
A method for operating an electronic device includes attaching a file to a first application program; generating an image corresponding to the file; and inserting the image into the first application program.
