Abstract
The described technologies leverage a trained evaluation function to analyze an email message to determine if a password is included in the text of the email message. The text of the email message may be vectorized using a character lookup table including vector values for each ASCII character. The trained evaluation function analyzes the vectorized text to determine if a password is included in the text of the mail message. An email message found to include a password may be placed in a quarantine storage to at least temporality prevent the email message from being disseminated to a recipient.
