The excerpt you provided discusses the importance of verifying the authenticity of emails, particularly when financial transactions are involved. The concern is that someone could forge an email, pretending to be someone else (like "vaprivalit" in your example), and trick the recipient into sending money to a fraudulent account. The author suggests that "reliable digital signatures" are the solution, as discussed in Simon Singh's book *The Code Book*.Here's a breakdown of why handwriting and email writing style aren't sufficient for trust, and why digital signatures are necessary:* **Handwriting:** While handwriting analysis can be used in some forensic contexts, it's impractical and unreliable for verifying emails. Emails are typically typed, not handwritten. Even if someone scanned a handwritten note and emailed it, forging handwriting is relatively easy.* **Email Writing Style:** While recognizing someone's typical writing style can be a helpful clue, it's not a foolproof method of authentication. Writing styles can be mimicked, and people's writing can vary depending on context and mood. Furthermore, sophisticated phishing emails often mimic legitimate organizations' styles very effectively.* **Digital Signatures:** These provide a cryptographic solution to the problem of verifying the sender's identity. A digital signature uses complex mathematics to ensure that: * The message truly originated from the claimed sender. * The message hasn't been tampered with during transit.This is analogous to a physical signature on a document, but far more secure and difficult to forge. Digital signatures are crucial for building trust and security in online communications, especially for financial transactions.
