Email Delivery Validation via Sender Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to effectively prevent unwanted electronic communications (spam) from being delivered to recipients, as they require users to read and identify spam messages, are susceptible to sender misrepresentation, and lack effective enforcement mechanisms, leading to increased spam attacks and disruption of legitimate communications.
Innovation Solution
A method and apparatus that selectively deliver email messages by validating sender addresses and trace data, requiring authentication from senders, using digital certificates, and flagging undesired information, while allowing users to manage unsubscribe requests and alert authorities to spam activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional spam blocking approaches (blocking undesired addresses or subjects) are used, then some spam can be filtered, but spammers can easily change their mailing domain names and these systems pass tremendous amounts of undesired spam while blocking desired mail
Solution Approach 1:
The system performs preliminary validation of sender addresses and trace data before delivering emails. It checks whether the sender's address format is valid, verifies trace data authenticity, and requires senders to respond to confirmation requests before their messages are delivered to recipients, preventing spam before it reaches users
Solution Approach 2:
The system introduces an intermediary validation process between sender and recipient. A third-party validation mechanism checks sender credentials, address formats, and trace data, and requires authentication responses before allowing email delivery, acting as a mediator that blocks spam while permitting legitimate communications
2Ease of operation
If unsubscribe features are provided in electronic communications, then recipients can request removal from mailing lists, but this provides spammers with information that the recipient's email account is active, leading to increased spam attacks
Solution Approach 1:
The system introduces a third-party intermediary that receives and processes unsubscribe requests on behalf of recipients. This intermediary validates the sender's address and communicates with spammers without revealing the recipient's active email address, thereby maintaining unsubscribe functionality while preventing spammers from identifying active accounts
Solution Approach 2:
The system extracts the unsubscribe request processing function from the recipient's email account and relocates it to a third-party service. This separation allows unsubscribe requests to be handled without exposing the recipient's email address to spammers, as the third party acts as a buffer that does not reveal account status
3Measurement precision
If users must read every email message to identify unwanted communications, then they can determine which messages are spam, but the burden becomes severe and legitimate correspondents are the last to learn of address changes
Solution Approach 1:
The system performs preliminary validation of sender addresses, trace data, and authentication responses before delivering emails to recipients. This pre-delivery verification ensures that only emails from authenticated senders with valid trace data are delivered, eliminating the need for users to manually read and identify spam messages

AI summary
The present invention relates to an apparatus and method for selective delivery of electronic communications to reduce the amount of unwanted email (spam) that is received. An electronic message is not delivered to a recipient until the sender address is verified. If the address is not verified, it can be compared to a database that includes known spammers. Also, records of spamming and forged emails can be compiled and forwarded to an enforcement agency.
