Abstract

A recipient communication device and method wherein a user authenticates a message that is being received. The method includes receiving, by a messaging utility of the recipient communication device, a message transmitted from a sender communication device. The messaging utility determines that one of (a) sender authentication of the message and (b) recipient authentication to open the message is required. In response to sender authentication being required, the recipient communication device transmits a request to the sender communication device for sender authentication of the message, and receives a certification of the message based on an authentication of a user input via the sender communication device. When recipient authentication is required, the recipient is prompted to enter biometric input at the recipient device. In one embodiment, a clearinghouse service authenticates a user of a communication device in order for the recipient communication device to receive certification of the user and/or the message.

Claims

1. A method for user authentication of a message that is being received by a recipient personal communication device, the method comprising:

receiving, by a messaging utility of the recipient personal communication device, a text-based message transmitted from a sender personal communication device;

identifying one or more keywords within the text-based message;

the messaging utility determining, based on identifying the one or more keywords within the message, that one of (a) sender authentication of the text-based message or (b) recipient authentication is required to open the text-based message; and

in response to sender authentication being required;

transmitting a request to the sender personal communication device for sender authentication of the message;

receiving a certification of the message based on an authentication of a user biometric input via the sender personal communication device, the biometric input comprising an image captured at the sender personal communication device, and the certification comprising a copy of the image; and

presenting the copy of the image on a display of the recipient personal communication device.

2. The method of claim 1, further comprising:

in response to recipient authentication to open the message being required;

prompting for entry of a recipient biometric input;

receiving the recipient biometric input at the recipient personal communication device;

authenticating the recipient biometric input by one of the messaging utility of the recipient personal communication device and a clearinghouse; and

presenting contents of the message on a user interface of the recipient personal communication device based on receiving the recipient authentication.

3. The method of claim 1, wherein receiving a certification of the message further comprises:

receiving a notification that a sender user has provided a biometric input that has been verified at the sender personal communication device or a clearinghouse as belonging to the sender user.

4. The method of claim 1, wherein receiving the certification of the message further comprises:

receiving the certification from a clearinghouse that verifies an identity of a sender user of the text-based message based on the clearinghouse receiving, from the sender user, a data entry that corresponds to sender-identifying information provided by an authoritative source.

5. The method of claim 1, wherein the image is a photograph of a sender user taken at the sending personal communication device.

6. The method of claim 1, further comprising:

receiving, as components of the message transmitted from the sender personal communication device, both (a) message content and (b) context associated with the sender personal communication device;

determining that sender authentication of the message is required by;

identifying a credibility-compromising factor associated with at least one of (a) the message content and (b) the context associated with the sender personal communication device; and

determining that the message requires user authentication based on the identified credibility-compromising factor satisfying a credibility threshold.

7. The method of claim 6, wherein the credibility-compromising factor comprises at least one of (i) a monetary value within the text-based message satisfying a predetermined threshold value;

(ii) the sender personal communication device being associated with a predetermined location; and

(iii) the sender personal communication device being associated with a location determined to be unexpected based upon historical or scheduled data for a sender user of the text-based message.

8. The method of claim 1, wherein receiving the certification of the message further comprises:

receiving a first certification that includes user information associated with the sender personal communication device or contextual information transmitted by the sender personal communication device; and

presenting one of the user information or the contextual information on a display of the recipient personal communication device.

9. A recipient personal communication device, comprising:

a communication mechanism that enables communicating with a network;

at least one biometric capturing component;

at least one processor that is communicatively coupled to the communication mechanism and to the at least one biometric capturing component;

a messaging utility that executes on the at least one processor and configures the recipient personal communication device to;

receive a text-based message transmitted from a sender personal communication device;

identify one or more keywords within the text-based message;

determine, based on the identified one or more keywords within the received message, that one of (a) sender authentication of the message or (b) recipient authentication is required to open the text-based message; and

in response to sender authentication being required;

transmit a request to the sender personal communication device for sender authentication of the message;

receive a certification of the message based upon an authentication of a user biometric input via the sender personal communication device, the biometric input comprising an image captured at the sender personal communication device, and the certification comprising a copy of the image; and

presenting the copy of the image on a display of the recipient personal communication device.

10. The recipient personal communication device of claim 9, wherein the messaging utility further configures the recipient personal communication device to, in response to recipient authentication being required to open the message:

prompt for entry of a recipient biometric input;

receive the recipient biometric input at the recipient personal communication device;

authenticate the biometric input using the messaging utility of the recipient personal communication device or a clearinghouse; and

present, based on receiving the recipient authentication, contents of the message on a user interface of the recipient personal communication device.

11. The recipient personal communication device of claim 9, wherein the messaging utility further configures the recipient personal communication device to:

receive a notification that a sender user provided a biometric input that was verified at the sender personal communication device or a clearinghouse as belonging to the sender user.

12. The recipient personal communication device of claim 9, wherein the messaging utility further configures the recipient personal communication device to:

receive the certification from a clearinghouse that verifies an identity of a sender user of the message based upon receiving, from the sender user, a data entry that corresponds to identifying information of an authoritative source.

13. The recipient personal communication device of claim 9, wherein the image is a photograph of a sender user taken at the sending personal communication device.

14. The recipient personal communication device of claim 9, wherein the messaging utility further configures the recipient personal communication device to:

receive, as components of the message transmitted from the sender personal communication device, both (a) content of the message and (b) context associated with the sender personal communication device;

determine that sender authentication of the message is required by;

identifying a credibility-compromising factor associated with at least one of (a) the message content and (b) the context associated with the sender personal communication device; and

determining that the message requires user authentication based on the identified credibility-compromising factor satisfying a credibility threshold.

15. The recipient personal communication device of claim 14, wherein the credibility-compromising factor comprises at least one of (i) a monetary value within the text-based message satisfying a predetermined threshold value;

(ii) the sender personal communication device being associated with a predetermined location; and

(iii) the sender personal communication device being associated with a location determined to be unexpected based upon historical or scheduled data for a sender user of the message.
