Stamp Authority System for Reducing Spam Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of unsolicited and unwanted electronic mail messages (SPAM) burdens users with significant time spent on deletion, leading to frustration and a poor user experience, prompting them to change service providers or reduce reliance on email messaging.
Innovation Solution
Implementing a 'stamp authority' system that imposes a transaction cost on senders by requiring valid stamps for email messages, which are validated by a receiving host, thereby incentivizing senders to use stamps and reducing SPAM volume by distinguishing or rejecting unstamped messages.

1Object-generated harmful factors
If a stamp authority system is implemented to require valid stamps for email messages, then the volume of SPAM is decreased by increasing transaction cost, but the device complexity increases due to stamp validation mechanisms
Solution Approach 1:
The stamp authority acts as an intermediary between senders and receiving hosts. It issues stamps to senders and validating hosts check these stamps before delivering messages. This mediator approach reduces SPAM by adding a verification layer without requiring direct complex interactions between all senders and receivers.
Solution Approach 2:
Stamps are issued in advance to senders before they send messages. The stamp authority pre-validates and distributes stamps to authorized senders, so that when messages arrive at receiving hosts, the validation process is simplified to just checking the pre-issued stamp rather than performing complex authentication at message time.
2Reliability
If receiving hosts validate stamps for all incoming messages, then message security and legitimacy are improved, but processing time and computational resources increase
Solution Approach 1:
Stamps are designed as simple, inexpensive validation tokens that can be quickly issued and validated. Rather than complex authentication credentials, stamps are lightweight data structures that receiving hosts can verify with minimal computational overhead, balancing security with processing speed.
Solution Approach 2:
The stamp authority distributes copies of validated stamps to multiple senders. Instead of requiring unique complex authentication for each sender, the system uses replicated stamp tokens that can be quickly verified. This copying approach enables parallel validation and reduces the computational burden on receiving hosts.

AI summary
Electronic messages may be processed using a stamp authority by receiving an electronic message, identifying a stamp associated the message, determining if the stamp is valid, and, if the stamp is determined to be valid, distinguishing the message from messages with which a valid stamp is not identified.
