Embedding biometric data from a wearable computing device in metadata of a recorded image

1. A method implemented by an imaging device, comprising:

recording an image of a subject to which a wearable computing device is secured;

responsive to the recording, wirelessly receiving data from the wearable computing device, the data including an identifier of the wearable computing device and biometric data of the subject; and

embedding the identifier and the biometric data as metadata in the recorded image;

estimating a position of the subject within the recorded image by:

receiving a reference image of the subject's face from the wearable computing device; and

performing a facial recognition algorithm to determine the position of the subject within the recorded image based on the reference image; and

embedding an indication of the position as metadata in the recorded image.

2. The method of claim 1 , wherein recording the image comprises transmitting a request for biometric data to the wearable computing device.

3. The method of claim 1 , wherein the biometric data includes an address of a biometric data server from which biometric data of the subject can be retrieved based on the device identifier.

4. The method of claim 1 , wherein the biometric data includes one or more sensor readings recorded by the wearable computing device.

5. The method of claim 1 , wherein the biometric data includes one or more mood indicators derived from sensor readings recorded by the wearable computing device.

6. A method implemented by a media server, comprising:

obtaining an image of a subject;

determining a timestamp and device identifier from metadata embedded in the image;

sending a request to a biometric data server to obtain biometric data, the request including the timestamp and the device identifier;

responsive to the sending, receiving biometric data that comprises a mood indication for the subject as depicted in the image; and

linking the image and the mood indication to a user account associated with the device identifier.

7. The method of claim 6 , further comprising:

determining a location of the subject within the image from additional metadata embedded in the image;

wherein linking the image and the mood indication to a user account associated with the device identifier also includes linking the location of the subject within the image to the user account.

8. The method of claim 6 , further comprising:

receiving a user request for images of the subject in which the subject is depicted in a specified mood;

based on the user request, determining a collection of images of the subject in which the subject is depicted in the specified mood; and

transmitting an indication of the collection of images as a response to the user request.

9. An imaging device, comprising:

a camera; and

one or more processing circuits configured to:

record an image of a subject to which a wearable computing device is secured, wherein the image is recorded using the camera;

responsive to the recording, wirelessly receive data from the wearable computing device, the data including an identifier of the wearable computing device and biometric data of the subject;

embed the identifier and the biometric data as metadata in the recorded image;

estimate a position of the subject within the recorded image by:

receiving a reference image of the subject's face from the wearable computing device; and

performing a facial recognition algorithm to determine the position of the subject within the recorded image based on the reference image; and

embed an indication of the position as metadata in the recorded image.

10. The imaging device of claim 9 , wherein to record the image, the one or more processing circuits are configured to transmit a request for biometric data to the wearable computing device.

11. The imaging device of claim 9 , wherein the biometric data includes an address of a biometric data server from which biometric data of the subject can be retrieved based on the device identifier.

12. The imaging device of claim 9 , wherein the biometric data includes one or more sensor readings recorded by the wearable computing device.

13. The imaging device of claim 9 , wherein the biometric data includes one or more mood indicators derived from sensor readings recorded by the wearable computing device.

14. A media server comprising:

a communication interface; and

one or more processing circuits configured to:

obtain an image of a subject via the communication interface;

determine a timestamp and device identifier from metadata embedded in the image;

send a request to a biometric data server to obtain biometric data, the request including the timestamp and the device identifier;

responsive to the sending, receive biometric data that comprises a mood indication for the subject as depicted in the image; and

link the image and the mood indication to a user account associated with the device identifier.

15. The media server of claim 14 , wherein the one or more processing circuits are further configured to:

determine a location of the subject within the image from additional metadata embedded in the image; and

link the location of the subject within the image to the user account.

16. The media server of claim 14 , wherein the one or more processing circuits are further configured to:

receive a user request for images of the subject in which the subject is depicted in a specified mood;

based on the user request, determine a collection of images of the subject in which the subject is depicted in the specified mood; and

transmit an indication of the collection of images as a response to the user request.
