Prevent Google Glass from Auto-Uploading Photos

Question

Google Glass automatically uploads every photo I take with it to Google's servers, and puts them in a private Google+ folder. I don't take nude pictures, I'm not a Google competitor and I have no interest in politics, but this is still too creepy for me; I don't want my pictures sent to Google without my approval. After systematically searching all the relevant menus, trying Google's Glass Explorer contact form and their phone support with no luck, I'm looking for a programmatic solution.

I have root access (using the unofficial method provided by Saurik, because the officially published method of unlocking the bootloader doesn't work.) Unfortunately, the relevant parts of Glass's software all seem to be closed-source; there was some noise in the press about it being open, but that turned out to just be the kernel, not the camera app, sync service or anything else. I considered setting up a cronjob to move pictures out of the default storage location soon after they're taken, but that breaks the Timeine. Looking through the list of process names with ps didn't suggest any obvious well-separated target to kill. I haven't configured network-sniffing to identify something to blackhole from /etc/hosts, but I don't consider this very promising because I'm not willing to break the builtin Google Search app.

Rewriting and replacing the entire camera app with one that saves to somewhere Google doesn't know about, seems like it would work; but it's too much work for me. Any other ideas?

EDIT 29Apr2014: With Glass version XE16.2, the auto-backup handling has been rewritten, adding a menu option in Settings to force the image upload to run if you don't want it to wait for it to be triggered by being plugged in with wifi. However, there is still no way to turn the uploader off. Also note that the log-message format has changed; to test whether Glass is uploading images, set up devtools, plug it in, take a picture and run

adb logcat |grep "Upload image/jpeg" 

EDIT 6May2014: There is a user report that Glass also uploaded images from a private album on an iPhone that was paired with it. I haven't been able to reproduce this on my Android/Cyanogenmod device, and don't have an iPhone handy to test with; can someone test this for me?

Answer 1

I don't use Google+ and only signed up for it to activate my glass, then disabled it. I was concerned about the same auto-upload issue and contacted support. They got back to me with the following: (SEE EDITS BELOW)

Hey Eric,

In regards to your question regarding Glass's auto-backup policy to Google Plus, I have received a definitive answer that your content will not be backed up if you have disabled the Google Plus Glassware on the MyGlass site or on the MyGlass app. If you have any further questions, feel free to reach out at 1-800-GLASSXE.

Best,

Bob

Edit:

Empirical evidence demonstrates this isn't true though. I was able to click an image in a Hangout and use it to navigate to an album of all images from my Glass.

1. Click on picture in hangout
2. Close slideshow (x in upper right corner)
3. Click "Photos" in navigation bar below the black "Join Google+" banner
4. Click "Highlights" in navigation bar below the black "Join Google+" banner

I also performed a test as outlined by jimrandomh below:

1. Enable debug
2. Enable wifi
3. plug in with a USB cable
4. run "adb logcat |grep AttachmentUploader"
5. take a picture

and the following printed

I/AttachmentUploader( 458): Uploading attachment of 933386 bytes to server, mimeType: image/jpeg, filename: 20131224_094130_897.jpg, source: device:d31658be9793f090

Indicating an image was uploaded to Google on an account that does not have Google Plus, a device that does not have the Google Plus Glassware installed, and the image wasn't shared with anyone.
