An example facial detection apparatus 102 for recipient message authentication is configured to transmit and/or receive electronic messages such as by using the communications interface 114, the processor 110 or the like. In instances in which the facial detection apparatus 102 is configured to transmit a message, an image search module 120 may be activated to locate, request and/or capture an image of one or more intended recipients of the message. In instances in which the facial detection apparatus 102 is configured to receive a message, an authentication module 122 may be configured to ensure a user is authenticated as a recipient by using facial detection before allowing the user access to the message.
In some embodiments, the image search module 120 may be configured to locate an image of an intended recipient to an electronic message. For example the image search module 120 may search a local memory, such as memory 112 for an image that identifies the intended recipient. Alternatively or additionally, the image search module 120 may be configured to search, such as over a network, an intranet and/or the Internet for an image that identifies the intended recipient. In instances in which an image is discovered over a network, the image may be provided back to the sender to verify the correct person has been identified. Alternatively or additionally, the image search module 120 may also cause a message to be transmitted such as by the processor 110, the communication interface 114 and/or the like to request a current image of the intended recipients. In some embodiments, the message may be transmitted directly to the recipient. If in response to an image request, an image is received; such a received image may be approved and/or accepted by the sender prior to the transmission of the message that is to be authenticated.
The image search module 120, the processor 110, and/or the like may then be configured to cause the located image to be encoded for transmission with the message. In some embodiments, the image may be transmitted as an attachment and/or by other means that may result in the image be transferred to a recipient device. However in some embodiments, the encoded image may be transmitted to a remote device, such as a remote facial detection apparatus 302 as will be discussed with respect to
In some embodiments, the authentication module 122 may be configured to authenticate a recipient of a message. In an instance in which a message that is to be authenticated is received, the authentication module may be configured to cause an image to be captured of a user attempt to access the image, such as by using the image capture circuitry 118. The image in some embodiments may be captured automatically and/or may be captured based on a prompt such as a prompt over the user interface 116.
The authentication module 122 may then be configured to determine whether there is a match between the intended recipient in a received image and/or a received plurality of facial features and the user in the currently captured image. In some embodiments a match may occur in an instance in which the number of similar features are greater than or equal to a determined authentication threshold. In instances in which the recipient is authenticated then a decryption key may be received to enable a message to be accessed.
Alternatively or additionally, in instances in which the recipient is not authenticated, then the authentication module 122 may be configured to prompt the sender with the captured image of the recipient to allow the sender to determine if indeed it was the intended recipient. Alternatively or additionally, the authentication module 122 may also cause an additional image to be taken for further processing. In either case until a recipient is authenticated, the message may not be accessed.
Alternatively or additionally, the authentication module 122, the processor 110, or the like may be configured to alter a received message based on the authenticated identification of a recipient. For example based on the authenticated recipient, the processor 110, the authentication module 122 and/or the like may be configured to change a theme, text content, and/or the like in the received message.

In an instance in which a number of similar features between the compared image and the received plurality of encoded features do not exceed a predetermined authentication level, as is shown in operation 612, the facial detection apparatus 302 may include means, such as the processor 110, the authentication module 122, or the like, for causing the decryption key to not be transmitted.
Advantageously, example message authentication allows the message sender to have control over who reads a message. In some examples, the activation of a send button in a message application may activate the facial detection apparatus 102. Alternatively or additionally, a recipient may not know that authentication has been performed unless the example message authentication as described herein fails. Such processes advantageously allow for ease of use by allowing for authentication to occur at the receiving mobile terminal. In some embodiments, the authentication may be conducted remotely to conserve processing power at the receiving device.
