Abstract
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.

SPECIFIC DESCRIPTION
The invention will now be described, purely by way of example, in connection with the appended drawings in which:
Figure 1 is a flow-chart representing part of a method in accordance with an embodiment of the invention;
Figure 2 is a screen capture taken from a smartphone programmed in accordance with an embodiment of the invention;
Figure 3 is a further screen capture taken from the smartphone of Figure 2; and
Figure 4 is a further screen capture taken from the smartphone of Figures 2 and 3.
With reference to Figure 1, there is shown a method 100 of sending private text messages 24 in accordance with an embodiment of the invention. The method is implemented on a smartphone’s applet. After the applet has been launched on the smartphone, the user can choose whether to send a private text message 24 or a standard text message 14.
The procedure 10 for sending a standard text message 14 is conventional: the text message 14 is entered, sent over a network 50, a copy of the standard text message 14 is stored in a local database and one is stored in a remote database on a server.
The smartphone, however, also enables the user to send messages privately. The applet provides for a ‘private chat’ mode 15. When the private chat mode 15 is enabled, the user can enter a private text message 24 for exchanging with any intended user. The procedure 20 for sending a private text message 24 is the following: the text message 24 is entered, a Javascript encrypts 22 the private message 24 and an encrypted message 25 is sent 23 over the network 50. Similarly to the procedure 10 for sending standard text messages 14, a copy of the encrypted, private message 25 is stored in a local database on the smartphone, and a copy remotely on a server.
If the private chat mode 15 is disabled, the user can enable the private chat mode by: (a) setting 40 for a first time a password 41 which henceforth will also form part of a user authentication procedure for authenticating the user on the smartphone to give him access to any private messages sent to him; or, (b) starting 30 the private chat mode by entering the password 41 on the smartphone to authenticate the user on the smartphone. When the private chat 15 mode is enabled, the user can: (a) send private text messages 24 according to the procedure 20 above described for sending private text messages; and/or, (b) access the content of any private text messages sent to him by other users. This manner of operation is better illustrated in Figures 2-4.
According to the method described herein, private text messages 24 are sent over the network 50 as encrypted messages 25. This improves privacy and security towards unauthorized and/or unlawful attempts to access these messages 25 while they transit over the network 50.
With reference to Figure 2, there is shown a screen 200 of a tablet showing a conversation between two users 201, 202. Each user can enable a private chat mode 15 as described herein on his device. Thus, the first user ‘Easan’ 201 has sent standard text messages 203 as well as private text messages 205 to the other user 202. The private text messages 205 are correspondingly enveloped, in Figure 2, by means of corresponding chat boxes 206 labelled ‘PrivateMessage’. On the other side, the second user 202 has also responded by uploading four standard text messages 213 as well as a single private text message 215. The private text messages 205, 215 are correspondingly enveloped, in Figure 2, by means of corresponding chat boxes 206 labelled ‘PrivateMessage’. These envelopes 206 serve to notify the users 201, 202, which as the case may be are one a sender and one a receiver of the text messages 203, 205, 213, 215, that the private text messages 205, 215 were sent as such, and that, correspondingly, can only be accessed as a result of a corresponding user authentication procedure. If the user Easan 201, or the other user 202, want to access the content of one or more of the private messages 205, 215 on their devices, they are required to go through the user authentication procedure to enable the private chat mode. In this case, the private chat mode is enabled to unencrypt read rather than encrypt the private messages. In this described embodiment, the user authentication procedure is in the form a password authentication procedure, described in connection with Figure 3.
With reference to Figure 3, a password dialog box 220 is shown for entering a password 221 to authenticate the users 201, 202 on the smartphone. A touch-screen numeric keypad 222 is also shown which in this embodiment allows the users to enter the required password 221, as necessary.
Entry of the user password 221 enables the private chat mode, whereby the user is now able on the one side to send private, encrypted messages as described above in connection with Figure 1, and, on the other side, to access by unencrypting any received private messages. The result of inputting the password 221 in the device is shown with reference to Figure 4.
With reference to Figure 4, there is shown the result of performing the user authentication procedure on the device of one of the users. In the described embodiment, the result of the authentication procedure is the revealing on the device of the content of the private message 215 uploaded by the second user 202. It is clear that many variation are possible, for example as a result of the authentication all privately enveloped messages 205, 215 could be revealed, or revealed at the touch of the touchscreen within the private chat mode.
The invention has above been described with reference to text messages, but the skilled person will appreciate that a variety of digital content may be exchanged between users using different embodiments of the invention within the scope of the appended claims. In particular, photo, video, digital currencies, files, voice recordings etc... are also equally privately exchangeable.
The skilled person will also appreciate that several stages of authentication are possible, i.e. not limited to one as described herein. Furthermore, these authentication stages may equally be linked to one or more of the steps of unencrypting the encrypted digital content and reproducing the unencrypted digital content. In the described embodiment, a single authentication stage has been used to activate both unencryption and reproduction, i.e. visualization on the screen 200 of the tablet, of the private text messages 205, 215.
