Abstract

A system and method for providing secure private electronic communications. An exemplary method includes encrypting a hidden message using an encryption scheme; encoding the encrypted hidden message in a source message; providing the source message having the encoded hidden message by a first electronic device; and transmitting a decryption key to a second electronic device. Moreover, the second electronic device can capture the encoded hidden message provided by the first electronic device, decode the hidden message, and extract the hidden message using the decryption key so that the hidden message can be rendered by the second electronic device.

First claim

What is claimed:

1. A method for providing secure private electronic communications, the method comprising:
encrypting, by a computer processor of a sending device, a secret message using an encryption scheme;
causing, by the computer processor, the encrypted secret message to be encoded in a source message by transmitting an encoding module and the encrypted secret message to a first electronic device that encodes the encrypted secret message using an encoding algorithm in the encoding module, the encoding module executed locally on the first electronic device;
causing, by the computer processor, the source message having the encoded secret message to be provided by the first electronic device; and
transmitting, by the computer processor, a decryption key to a second electronic device, such that the second electronic device can capture the encoded secret message provided by the first electronic device, decode the secret message, and extract the secret message using the decryption key so that the secret message can be rendered by the second electronic device.

2. The method according to claim 1 , further comprising encoding, by the first electronic device, the encrypted secret message in the source message by modifying pre-defined black and grey borders of source text letters in the source message.

3. The method according to claim 1 , wherein the causing of the source message having the encoded secret message to be provided by the first electronic device comprises displaying the encoded secret message in the source message on a display screen of the first electronic device.

4. The method according to claim 3 , further comprising capturing, by a video camera of the second electronic device, the encoded secret message displayed on the display screen of the first electronic device.

5. The method according to claim 1 , wherein the causing of the source message having the encoded secret message to be provided by the first electronic device comprises providing the encoded secret message by the first electronic device to the second electronic device by one of near-field communication, Bluetooth communication, and bump/vibration communication.

6. The method according to claim 1 ,
wherein the causing of the encrypted secret message to be encoded in the source message comprises encoding the encrypted secret message in the source message by the computer processor, and
wherein the causing of the source message having the encoded secret message to be provided by the first electronic device comprises transmitting the encoded secret message to the first electronic device to be displayed thereon.

7. A system for providing secure private electronic communications, the system comprising:
electronic memory configured to store a decryption key for an encryption scheme; and
a computer processor of a sender device configured to:
encrypt a secret message using the encryption scheme,
causing the encrypted secret message to be encoded in a source message, by transmitting an encoding module and the encrypted secret message to a first electronic device that encodes the encrypted secret message using an encoding algorithm in the encoding module, the encoding module executed locally on the first electronic device;
causing the source message having the encoded secret message to be provided by the first electronic device
transmit the decryption key to a second electronic device, such that the second electronic device can capture the encoded secret message provided by the first electronic device, decode the secret message, and extracts the secret message using the decryption key so that the secret message can be rendered by the second electronic device.

8. The system according to claim 7 , wherein the first electronic device is configured to encode the encrypted secret message in the source message by modifying pre-defined black and grey borders of source text letters in the source message.

9. The system according to claim 7 , wherein the computer processor is further configured to cause the source message having the encoded secret message to be provided by the first electronic device by instructing the first electronic device to display the encoded secret message in the source message on a display screen of the first electronic device.

10. The system according to claim 9 , wherein the second electronic device comprises a video camera configured to capture the encoded secret message displayed on the display screen of the first electronic device.

11. The system according to claim 7 , wherein the computer processor is further configured to cause the source message having the encoded secret message to be provided by the first electronic device by instructing the first electronic device to provide the encoded secret message to the second electronic device by one of near-field communication, Bluetooth communication, and bump/vibration communication.

12. The system according to claim 7 , wherein the computer processor is further configured to encode the encrypted secret message in the source message and transmit the encoded secret message to the first electronic device to be displayed thereon.

13. A non-transitory computer readable medium comprising computer executable instructions for providing secure private electronic communications, including instructions for:
encrypting a secret message using an encryption scheme at a sender device;
causing the encrypted secret message to be encoded in a source message by transmitting an encoding module and the encrypted secret message to a first electronic device that encodes the encrypted secret message using an encoding algorithm in the encoding module, the encoding module executed locally on the first electronic device;
causing the source message having the encoded secret message to be provided by the first electronic device; and
transmitting a decryption key to a second electronic device, such that the second electronic device can capture the encoded secret message provided by the first electronic device, decode the secret message, and extracts the secret message using the decryption key so that the secret message can be rendered by the second electronic device.

14. The non-transitory computer readable medium according to claim 13 , further comprising instructions for encoding, by the first electronic device, the encrypted secret message in the source message by modifying pre-defined black and grey borders of source text letters in the source message.

15. The non-transitory computer readable medium according to claim 13 , wherein the causing of the source message having the encoded secret message to be provided by the first electronic device comprises displaying the encoded secret message in the source message on a display screen of the first electronic device.

16. The non-transitory computer readable medium according to claim 15 , further comprising instructions for capturing, by a video camera of the second electronic device, the encoded secret message displayed on the display screen of the first electronic device.

17. The non-transitory computer readable medium according to claim 13 , wherein the causing of the source message having the encoded secret message to be provided by the first electronic device comprises providing the encoded secret message by the first electronic device to the second electronic device by one of near-field communication, Bluetooth communication, and bump/vibration communication.
