US Patent 10021114 Determining the legitimacy of messages using a message verification process

A server computer receives an indication of an interaction between a first user device of a first user and a second user device of a second user, where the interaction includes a message for transmission from the first user to the second user. The server computer performs a verification process on the message, including performing one or more binary checks on the message. The server computer then generates a response indicating whether the message is a legitimate message based on the verification process. When the response indicates that the message is a legitimate message, the server computer transmits the message to the second user device of the second user for display.
