EFF is asking computer users not to trust Google Desktop. In case you have never used it, Google Desktop is an application that allows you to use Google's indexing algorithms in your computer, letting you search your files and emails. It is a very useful application, particularly when you want to navigate large number of files and emails to find information. However, I have always been concerned about who has access to the files. With new features, some of the indexes will be stored in Google. This is indeed worrying. While I cannot think of anything in my computer that I would deem sensitive, the idea of my emails and files stored in Google's servers makes me uneasy. What stops them from searching through the files to make direct marketers aware of my tastes?
