Email Delivery Apparatus with Hidden Letter Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic mail delivery systems fail to prevent erroneous transmissions due to habitual and superficial mail address checking, leading to potential information leakage.
Innovation Solution
An electronic mail delivery system that sets a hidden letter part of the mail address, requiring the sender to re-enter a specific letter for verification before delivery, ensuring accurate address checking and preventing incorrect transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a checkbox is provided for mail address checking, then the transmission process is simplified and faster, but the checking operation loses substance and becomes habitual, leading to erroneous transmission
Solution Approach 1:
Instead of requiring verification of the entire mail address (which would slow down transmission), the system hides only a part of the mail address (e.g., one character) and requires the sender to correctly input that hidden part. This partial verification action maintains transmission speed while effectively preventing erroneous transmissions by ensuring the sender actually checks the address.
2Reliability
If the entire mail address is hidden and requires re-entry, then address checking effectiveness is improved, but the operational burden on senders increases
Solution Approach 1:
The system hides only a portion of the mail address (such as one character) rather than the entire address, requiring the sender to input only that hidden part for verification. This partial action approach maintains high reliability by ensuring address checking while keeping the operational burden minimal for the sender.

AI summary
Various embodiments prevent erroneous transmission of electronic mails and therefore forestall information leakage in an electronic mail delivery apparatus. When an electronic mail is to be transmitted, a hidden letter selection unit presents a mail address specified as a transmission destination or source of the electronic mail with a part of the mail address presented as a hidden letter part. If a correct letter is entered in the hidden letter part of the mail address, a selective mail delivery unit executes the transmission of the electronic mail. If a correct letter is not entered in the hidden letter part of the mail address, the transmission of the electronic mail is stopped. Thereby, the effectiveness of operation for mail address checking can be improved, and the checking operation can be prevented from losing substance.
