The Salesforce software giant has won a patent that shows how a blockchain-based platform can be used to prevent spam or other unwanted emails from harassing people's inboxes.
According to a document published Tuesday by the United States Patent and Trademark Office, a blockchain-based platform can be exploited to check if e-mails have been modified or otherwise tampered with after being sent through a personalized correspondence system. Furthermore, according to the document, this system can filter spam more efficiently than existing protocols.
The proposed platform would use a matching system to determine if a & # 39; e-mail sent was legitimate or not. Basically, when a user sends an email, a part will be recorded on a blockchain platform. When a second e-mail server receives the message, it compares a component to determine if it matches the section recorded on the blockchain.
If the components match, the email will continue in the inbox, while if there is a discrepancy, the email will be marked as spam.
This system "can help to ensure that messages and attachments to these messages have not changed during transit on a network", according to the deposit.
Explain that "messaging systems are often misused and used to distribute unwanted or unwanted messages (or other network traffic), which are commonly referred to as spam." In addition, spammers have a low barrier to entry, which makes it useful to continue sending such emails.
Furthermore, while spam filters are currently common, they sometimes turn out to be false positives. The use of a blockchain platform can reduce the number of false positives through the proposed matching system, the document states.
The patent explains:
"The [system] it can also better identify legitimate (desired) messages and distinguish them from illegitimate (unsolicited) messages. If used correctly, the immutability and the distributed nature of the blockchain may make it impossible to change the information once the blockchain has been committed. "
The use of an immutable ledger also applies to "all information, which may include information such as sender and recipient," he adds.
Other uses of the concept could also help to ensure the authenticity of medical records, educational transcripts, deeds, property rights, legal documents and more, the authors say.
Salesforce, which operates a cloud-based e-mail distribution platform, among other products, has expressed an interest in exploiting the blockchain in the past. In March, its chief executive, Mark Benioff, said the company was trying to build a product using blockchain for some time in 2018, although it did not provide details on the project.
