Google+ is still in the testing phase so things are constantly changing. Here is a list of ongoing privacy issues. Please suggest new entries in the comment section.
The biggest discussions are centered around photo privacy. There are multiple issues.
- Be careful what you include in albums when tagging a single photo. When you tag someone in a photo, that person is notified and given a link to that photo but they will also have access to your entire album, not just that single photo.
- Joining Google+ changes the privacy settings of your Picasa albums. You’ve recently joined Google+. Note the following changes to Picasa Web Albums:
- Albums you’ve shared can in turn be tagged and shared by others.
- For new albums, anyone an album is shared with can see who else it is shared with.
- When you tag someone, they receive a notification and can see the photo and the related album.
- Albums you share within your circle can be reshared with those outside your circle if someone in your circle reshares them.
- Using Chat may expose your email address. Users are warned when they enable Chat for the first time. When you appear in someone’s chat list in Google+, it’s possible that person could discover your email address. While your email address won’t be displayed in the chat list in Google+, it is displayed in the chat lists of other Google products (Gmail and iGoogle, for instance). The members of chat lists are consistent across Google products.
- Email address may show in auto-complete field when adding someone to a stream update. Discuss.
- Geo location in photo’s exif will be displayed if ‘show geo location’ is enabled. I suspect this will become a problem for Google. Facebook specifically hides exif data for privacy reasons. Let’s say Jane is being stalked by an ex-boyfriend or some unknown stranger. She now lives in an unknown city. Her friend takes a picture of her with a gps enabled phone and uploads it to a public album and labels it ‘Great party at Jane’s house’. Now everyone will know exactly where Jane lives. Read more. Discuss.
