More worries for Beijing visitors

If you are headed to (or already at) the Olympic Games and you weren’t worried by my Tech Tips for Beijing Visitors at the end of last month, maybe you should be now,

In telling the Wall Street Journal’s readers “Don’t Forget About China’s Dissidents,” Ellen Bork notes at the tail end of her piece:

The world isn't just sending athletes to the Olympics, but surveillance technology that will help the government keep tabs on its people for years to come. American companies alone have sold China technology that invisibly copies computer hard drives, reads encrypted text and performs facial recognition analysis on surveillance video.

So, even if you store your photos, documents and other files on a hard drive, they may not be safe from duplication. Your notes may be decrypted. And your face picked out of a crowd, as you move about.

Have fun. Carefully.
