Cross-Application Private Metadata for Enhanced Social Photo Capabilities

With high-quality cameras integrated into smart phones, smart phone capabilities such as Global Positioning Systems (GPS) and timestamps are easily added to photograph (photo) metadata. Use of metadata in photos has long been a feature of advanced cameras; however, smart phones have additional web capabilities such as social network integration. For example, a smart phone can easily be used to take a photo and upload that photo to a sharing website.

Applications (apps) on the smart phones are also a potential source of data for use in captured photos, and a source that can be dynamic and interactive. For example,

when taking a photo, social network applications might be able to provide useful metadata to embed in the photo. However, adding social metadata requires privacy controls and server-side interaction for efficient storage, lookup, and usage. When encoding the data for privacy, the captured information would also be available only to the particular service that captured the data.

The disclosed system leverages smart phone applications for dynamically collected metadata for novel social capabilities during photo upload and sharing, while

maintaining data privacy and allowing cross-application data sharing. The novel system queries device apps to generate metadata upon taking a photo. It encodes private data for use as photo metadata and unlocks photo metadata through other web services. The system takes advantage of unlocked photo metadata to facilitate enhanced social capabilities.

The system enhances smart phone photo capture and social network photo processing. To implement this system in a preferred embodiment:

1. User takes a photo with a smart phone or similar device 2. Smart phone queries an app on the device to determine whether any want to embed additional metadata in the photo 3. Participating apps generate data, possibly by leveraging the smart phone capabilities and communication with web services 4. Those apps store data either on the device or web service, and provide an encoded metadata token to the camera app 5. Later, the user uploads the photo to a social service 6. The social service identifies any proprietary metadata embedded in the photo 7. The social service has the user log into the service that generated the metadata to unlock the data
8. The full data set is sent back to the social service
9. The social service can use the entire data set to leverage social capabilities

Example uses include, but are not limited to:

• Sharing the photo with friends who were nearby when the photo was taken
• An application contributing metadata to identify friends in the photo


• An application contributing in depth technical diagnostic information for a

complex device being photographed (e.g., an automotive or aviation part, mining
