Ghost messages
Communication security depends above all on the attention that apps pay to their users who can make impromptu use of messages sent or received. To ensure secure and discreet communication Blowfish adopts ghost messages. These messages are visible both for those who send them and for those who receive them only once. In this way, an improper use of the contents received by a possible sender will be impossible since the chat screen shot is made difficult by the obfuscation of the message which will disappear when the chat itself is closed. Unauthorized reuse of the message will be impossible and communicating private content in this way becomes more secure.
