Email Privacy Enforcement via Bcc Field Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing email systems fail to prevent users' email addresses from being propagated and used in mass mailings, leading to unwanted messages and resource wastage, as addresses in 'To:' and 'Cc:' fields can be easily added to address books and forwarded, making it difficult to detect spam and hoaxes.
Innovation Solution
A system that automatically moves email addresses from 'To:' or 'Cc:' fields to 'Bcc:' fields when a threshold number of recipients is exceeded, ensuring privacy by making the addresses inaccessible to recipients and preventing them from being added to address books.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If e-mail addresses are included in 'To:' or 'Cc:' fields for easy delivery and address book population, then message delivery efficiency is improved, but user privacy is compromised and spam propagation increases
Solution Approach 1:
The patent introduces a server-side intermediary system that sits between the e-mail client and the e-mail network. This server automatically intercepts outgoing messages, detects the presence of the user's e-mail address in 'To:' or 'Cc:' fields, and redirects it to the 'Bcc:' field when privacy protection is enabled. This intermediary mechanism allows the system to maintain normal e-mail delivery functionality while secretly protecting user privacy by preventing address propagation.
2Ease of operation
If e-mail addresses in 'To:' and 'Cc:' fields are easily accessible for address book population, then ease of operation is improved, but unwanted messages and resource wastage increase
Solution Approach 1:
The patent implements preliminary action by proactively protecting e-mail addresses before they can be misused. When a user composes a message and includes their e-mail address in the 'From:' field with privacy protection enabled, the system pre-emptively redirects this address to the 'Bcc:' field in outgoing messages. This preliminary redirection prevents the address from being copied into recipient address books in the first place, thereby preventing future spam and unwanted messages before the problem can occur.
3Adaptability or versatility
If e-mail addresses are propagated through address books for legitimate communication, then communication versatility is improved, but detection of spam and hoaxes becomes difficult
Solution Approach 1:
The server-side intermediary system maintains communication versatility by allowing legitimate e-mail delivery while adding a layer of privacy protection. The intermediary transparently redirects e-mail addresses to 'Bcc:' fields without disrupting the normal flow of communication. This allows users to continue communicating with their address books as before, while the intermediary simultaneously prevents spam propagation by ensuring protected addresses never appear in recipient fields where they could be copied and misused.

AI summary
A system for forcing e-mail addresses into the Bcc: field of transmitted messages in order to enforce user privacy. A user interface enables a user to indicate that their e-mail address is not to be included in a “To:” or “Cc:” field of an e-mail message from another user when the number of e-mail addresses contained in those fields exceeds a threshold size. The user's e-mail address and the associated threshold are stored for future reference when new messages are sent by the other user. Subsequently, when a new message is generated by the other user in which the number of e-mail addresses contained in the “To:” and/or “Cc:” field exceeds the threshold, then the disclosed system moves the user's e-mail address from the “To:” or “Cc:” field to the “Bcc:” field of the message before the message is transmitted to its recipients. Privacy messages may either be sent individually to specific users, or may be automatically generated as a result of a general privacy setting being indicated by the user.
