IT Intelligence Bulletin (HG Insights) — Salesforce has won a patent to use blockchain technology to detect and prevent spam from entering inboxes.

According to the patent published on the U.S. Patent and Trademark Office (USPTO) website recently, Salesforce believes that this protocol can more efficiently filter spam than existing approaches.

The patent describes the low barrier of entry marketers face when sending unsolicited bulk email messages, from almost zero operating costs to little in the way of recourse for recipients of spam emails, which has led to the huge volume of unsolicited messages. Despite several leading email services providing spam filters that are both automated and customizable, filters can still produce false positives such as emails erroneously marked as spam.

To improve the system, Salesforce would use a two-server delivery system that records portions of the message to ensure it has not been tampered with before reaching the inbox.

The application reads:

  • To address the issues discussed above, systems and methods are provided that use blockchain (or equivalent) technologies to address challenges presented in message delivery and integrity. In one embodiment, a messaging system is provided that includes a first message server, a second message server and a distributed database system that stores a blockchain.

Earlier this year, Salesforce co-founder Marc Benioff said: “I had been thinking a lot about what is Salesforce’s strategy around blockchain, and what is Salesforce’s strategies around cryptocurrencies and how will we relate to all of these things.”
