An Internet-based system which enhances the safety of travelers, operated via website or mobile messaging text messages. The user provides identity and contact details for himself/herself and a contact person. The user then provides travel plan information and an alert time, thus arming a monitoring process which monitors for alert time expiry. If the user disarms the system no alert notification will occur. Should the user fail to disarm before the alert time, or if an emergency activation message is received from the user, the contact person is alerted by email and/or text message and notification information is made available on a secure notification website. Other embodiments are described.
