Comment: Locational Privacy

From the Electronic Frontier Foundation: There's a New York Times piece on the way that in the space of a few years, locational privacy has gone from near absolute to practically zero, as a side effect of new convenient technology:

What can be done? As much as possible, location-specific information should not be collected in the first place, or not in personally identifiable form. There are many ways, as the Electronic Frontier Foundation notes, to use cryptography and anonymization to protect locational privacy. To tell you about nearby coffee shops, a cellphone application needs to know where you are. It does not need to know who you are.

When locational information is collected, people should be given advance notice and a chance to opt out. Data should be erased as soon as its main purpose is met. After you pay your E-ZPass bill, there is no reason for the government to keep records of your travel.
