With the outbreak of innovative applications, information security is a prerequisite for the development of technology applications. In addition to focusing on anti-virus and anti-malware software, Taiwanese industry players use blockchain technology to ensure the authenticity of email data and develop webmail extension that can identify suspicious senders.
Email scam upgrades, letter changes cause millions of losses
Business Email Compromise (BEC) is one of the most high-profile security threats in recent years. Scam groups do not even need to contact real people. They can be fooled by ordinary emails, causing huge losses.

He saw the problems of BEC, so he introduced Postchain, the underlying structure of the Swedish blockchain, and integrated the opinions of scientific and technical experts. He used the characteristics of undeniable, none-tamperable, and permanent storage of blockchain data to lead the team to independently develop and apply personal and corporate agility The information security solution of the current data, and in the early January released the ChkSender blockchain email authenticity verification tool to lock in the services provided by webmail users worldwide.
Patented email verification tool identifies suspicious sender source
ChkSender is a browser extension suite that seeks to confirm that the origin of the sender and the content of the message have not been altered while not changing user habits. The sender can store the digital fingerprint of the message to the blockchain or send the message encrypted with a password.
