IBM bans Siri from their network. If you work for IBM, you can bring your iPhone to work, but forget about using the phone’s voice-activated digital assistant Siri. The company is worried that the spoken queries might be stored somewhere. And they’re right. When you use Siri or Dictation, the things you say will be recorded and sent to Apple in order to convert what you say into text. Siri also collects other information including names of people from your address book and other unspecified information… all of this to help Siri do a better job. And Apple doesn’t mind its iPhone 4S users uploading data to its datacenters. If anything, the more the better. The more data Siri receives, the better Siri becomes.
IBM is right to block off Siri, and its right to take precautions. IBM also bans Dropbox and similar cloud services. Siri and the Dictation feature can be used to write emails, text messages, and store other information that IBM may not want being uploaded to Apple before it is downloaded back to the iPhone.
