Google to strip unique client ID from future Google Chrome installs
Google's official word on the matter has always been that the client ID is only used to determine when a user requires updates and by the crash reporter (a feature which isn't enabled by default). Nevertheless, they've decided the identifier won't be a permanent part of future Chrome releases.
According to details published in a new data protection whitepaper, Google reports that future versions of Chrome will only require the unique ID to check for the first automatic update. Once that update has been successfully installed, the ID is removed.
Privacy-minded folks like the developers of SRWare Iron still have other concerns, of course -- like omnibar suggestions, alternate error messages, and the Chrome updater.
