When there are just too many, they can be considered unwanted. And nobody likes spam emails.
While we do have spam filters available where the technology has become a commonplace. But still, they sometimes result in false positives. Software giant Salesforce has won a patent in which the company can use a blockchain-based platform to prevent spam or other unwanted emails from plaguing people's inboxes.
Using a blockchain platform, according to Salesforce, can reduce the number of false positives through its proposed matching system.
According to a document published by the U.S. Patent and Trademark Office, a blockchain-based platform can be leveraged to check whether emails are changed or otherwise tampered with after being sent through a custom matching system.
This system can also be a more efficient spam filter than existing protocols, according to the document.
The concept is with the technology in recording a portion of an email when it is sent, onto a blockchain platform. When a second email server receives the message, it will compare the component of the email to determine whether it matches the section previously recorded onto the blockchain.
If the components match, the email is considered legitimate, in which the system will continue the email to the recipient's inbox. But if the emails' components don't match, the system will mark the email as spam.
This system "can help ensure that messages and attachments to those messages have not been modified during transit over a network," according to the filing.
It explains that "messaging systems are often abused and used to distribute unwanted or undesirable messages (or other network traffic), which are commonly referred to as spam." And since spammers have a low barrier to entry, it makes it worth while for them to continue bombing people's inboxes with such emails.
It also adds that using an immutable ledger, similarly applies to "all information, which can include things like sender and recipient information."
Broadening the possibilities, the concept could also help guarantee the authenticity of medical records, educational transcripts, deeds, property rights, legal documents, and more, the authors say.
Salesforce, which runs a cloud-based email distribution platform, among other products, has expressed interest in leveraging blockchain before. In March, its CEO, Mark Benioff, said the company was looking into building a product using blockchain as one of the company's focus.
Given how widespread spam is, and how spam filters may not work as intended due to incorrect settings, Salesforce's solution shows how an open distributed ledger can potentially end, or at least minimizes spams.
