A method of exchanging private digital content, or performing secure messaging, over a network. Using a network-interactive electronic device, digital content is made available for exchange, for example by creating 21 the same or by selecting it from the memory of the device. The digital content is then encrypted 22 and sent 23 over the network to an intended user. Using another device, the intended user receives the encrypted digital content and is notified of its reception by means of a private message envelope. An authentication procedure to authenticate the intended user on the network-interactive electronic device needs to be performed for the enveloped, private digital content to be decrypted and/or reproduced i.e. the recipient user is required to enter a password or PIN to reveal the encrypted content. The authentication performed is one to access the private chat mode of the content exchange/messaging application. One embodiment relates to a secure messaging system wherein messages are encrypted and password/PIN authentication is needed by the recipient to decrypt and reveal the received message(s). Biometric e.g. fingerprint authentication may also/alternatively be used. The sender may be given the option 15 of sending a normal or encrypted (private chat mode) message. |
