A byproduct of life in the 21st Century is that many of the perks of a post-centennial lifestyle require the abdication of a fair bit of privacy to cyberspace. That means that the paper records that once required a search warrant to read (and maybe the forceful extraction from your cold-dead-hands), are now in the possession of companies who don't. Of course there's Facebook and Twitter. Those didn't exist in the 20th. Century. But, what about your phone records and email? While your phone company has long been subject to a warrant or subpoena, in the 21st. Century new "self-service" tools have been developed to help telcos manage the onslaught of requests made particularly attractive by the fact that most of us carry what amounts to a homing-beacon in our pockets. Similarly, while email has always been an attractive source of discovery, until recently most of it resided on each correspondent's physical, and virtual, desktop waiting to get written-over by something more current. Today, it's more likely been put out to pasture in a seemingly-endless "server farm", waiting to be picked by a custodian of records.

Even our personal computers, which have always required a search warrant, and often require a cascading series of search warrants covering various regions of storage space and categories of searches, are rapidly being replaced by windows to the web -- sleek sheets of glass and sculpted-aluminum that act as a portal to your virtual existence. Like a supermodel, these tablets are thin and beautiful, but two-dimensional, with very little substance inside. What makes these devices a reality today is a combination of near-ubiquitous Internet connectivity and access to your personal online data once it's established. Even the notion of "backing up" is becoming a thing of the past, because the data you see, isn't really here. It's somewhere else, presumably safe from destruction, but not necessarily from dissemination. Like many things in life, it's a trade-off.

But, not when it comes to fighting crime. The shift of discovery from physical space to cyberspace is a decided advantage for law enforcement. In fact, Google reports that it responded to more than 4200 discovery requests in the first-half of 2010 alone. One of the reasons these requests have become so popular is that online data is easier seize than a laptop, and often much more useful. Much of what can be had requires no search warrant at all, and thanks to online tools, can be had without even so much as contacting the service provider. Why? Because, unlike the data on your hard drive, you don't necessarily own your data when it's stored in cyberspace.

The Electronic Communications Privacy Act was enacted by Congress in 1986 -- long before most people had access to the Internet, email, or a cellphone. When Mark Zuckerberg's only friends were his stuffed animals. Mind you, it was revolutionary for it's time -- enacted to extend government restrictions on wire taps from telephone calls to also include transmissions of electronic data by computer. But, it doesn't address current evolution. Today, far more can be gleaned from a historical records search than any telephone wiretap. Perhaps that's why last year the Department of Justice argued in favor of warantless email searches. Or why in the same year the DOJ argued that cellphone users had abdicated any expectation of privacy by using a service that stores location data.

How Google might know what you did last summer -- even if you forgot.

Google Latitude is a service that allows users to see and share their location on a Google map live and in real-time. The service runs on most smart-phones, regardless of service provider, including Apple's iPhone, Windows Mobile, the Palm Pre, and, of course, Google's Android. Latitude relies on a combination of GPS, cellular tower triangulation, and wi-fi triangulation. Having brushed-up on the service for a recent National Public Radio (NPR) Interview, I have since considered Latitude one-part creepy, and two-parts cool. However, the creepy / cool ratio may be shifting.

This week Google introduced a new and improved Google Latitude -- with enhanced features like "Location History".  With Location History Latitude users can go back in time retrace their footsteps, and even see where they stayed-put, and for how long. Kind of cool...yet, very creepy. But practical?

Imagine, for example, you're the owner of a Palm Pre on Sprint's 3G Now Network , having trouble remembering where your were when you told your spouse you were somewhere else? Now, there's a map for that!

But wait -- there's more! How about "Location Alerts"? Certainly, a application that would alert you when a particular individual, say a family member, has left work or school, would be very practical. After a while of being alerted every time someone is, or has arrived, exactly where you would expect them to be, however, could get old. So, Google's geniuses stepped it up a notch. According to Google, Latitude will learn user's patterns and behavior so that alerts can be issued when a person has strayed from their routine -- left at a different time, or arrived at a different place.

For example, if you decide to staycation with your mistress, you can receive a handy alert when your spouse leaves the office earlier than usual. Or, if traffic is particularly light, Latitude will let you know when it's time for a quick window-exit.

Best of all, when the jig is up, no one has to know, because -- for now -- Google is making all these free services available to you, and no one else... at least, without subpoena powers.

This is deception... on the Now Network.

Recently, I had a wonderful opportunity to play a game of hi-tech "phone tag" on the streets of San Francisco with Reporter Martin Kaste from NPR's "All Things Considered". Late last Summer I was  asked if I would be willing to sit down for an interview for a story he was researching about location privacy. But, instead of agreeing to meet Kaste, I told him he had to find me.

With the aid of his GPS-equipped smart-phone, some software, a little patience, and a good pair of walking shoes, he was able to "tag" me sipping a latte outside a coffee shop on Market St. Of course, with my own GPS, and software-equipped smart-phone, I was able to see him coming. What follows are the fruits of that encounter:

Digital Bread Crumbs: Following Your Cell Phone Trail

Jeff Fischbach is a little bit like those guys in The Matrix — when he puts on his shades and looks at the world, he sees data.

Walking down the street in San Francisco, he points out all the devices that record people's comings and goings: digital parking meters, apartment intercom systems, digital security cameras...

How Twitter says they'll hide your location from twits with subpoenas.

Recently, Twitter announced that they would be adding geolocation features to their service, allowing users to embed their physical location in their Twitter feed. As not to alarm: Twitter has always maintained that this would be an opt-in feature. But, frankly, any web site you visit is privy to some information about your physical location by virtue of the IP address assigned to your computer by your Internet Service Provider (ISP) from a group of IP addresses reserved for your neighborhood. The logs kept by a web server, combined with a subpoena to the appropriate ISP, usually yield a street address for the subscriber assigned that IP address.

SmarterWare's Gina Trapani (formerly of Lifehacker.com) is attending the Twitter Conference in LA. She's posted updates explaining how Twitter plans to deploy this service and how they intend to protect its Twitter geolocation users from subpoenas. According to Gina, "Twitter will scrub geo-data stored in tweets more than 14 days old to avoid getting subpoena’d about a user’s location in the past. They will outright delete the location information from their database, not just anonymize."

She also reports that while,

"Twitter usually encourages developers and applications to cache data, in the case of geo, they recommend dropping historical location data so that application developers don’t become a subpoena target, either. They also recommend 'fuzzing' location and time data, so that instead of knowing that Joe Smith was at 8th avenue and 15th street at 2:11PM Eastern time on March 7, 2008, you only show that Joe was in Brooklyn on that day. The geodata-scrubbing isn’t a permanent solution. They are looking into ways to store this data in a 'safe' (anonymized?) way in the future, so they won’t always scrub +14 day old data, just at first."

Purging data that isn't mission critical, but likely to be subpoenaed makes a lot of sense. After all, no one writes "Satisfy search warrants in a timely, efficient, and effective manner" into their corporate mission statement.

While I'm convinced that Twitter's motivation is for the sanctity of the corporation, rather than its user-base, it is a step in the right direction. In fact, the direction is so right that one has to wonder why all personally identifiable user data isn't "scrubbed" every 14 days from most online services. Of course, Twitter's raison d'être, is -- among other things -- to give it's user's messages some life and legacy. It's likely that most of those users would also like to take credit for their various flashes of 140 character brilliance.

Not so, however, every time an individual fires off an instant message (IM), or searches Google. Most instant messaging services, for instance, don't store messages after they are sent, but they do store the sender and recipient's IP addresses, with their account information, and the time they logged in. While Google relies on demographic data, such as geography, income, and search interests, in order to sell ads, it doesn't need to be personally attributable to me. Companies like Google, Yahoo!, Facebook, MySpace and AOL are not in the subpoena response business. But, all of these companies employ subpoena compliance personnel, who add to the cost of doing business, but contribute nothing to the bottom-line. Worse yet, where nearly every individual in these companies, in some way, does something, either directly or indirectly, to add to the end-user experience, subpoena compliance often works in direct opposition to that objective.

As many companies learn when they're sued, subpoena compliance is often so expensive that it's cheaper to settle. A company can't be forced to produce what they don't have. And, with some significant exceptions, a company can't be forced to archive what they don't need.

By the way, I'm not just an end-user of all the services listed above, I'm also one of the twits writing the subpoenas.

At just 2.8 x 2.9-mm (smaller than the head of a matchstick, and thinner than a stick of gum), Epson's Infineon XPOSYS Assisted-GPS chip could literally bug the heck out of you. Smaller and more powerful than any A-GPS before, it can even track indoors. On the plus-side, you may never loose another left-sock again.

The first set of mass-production plug-in electric vehicles are slated to arrive this year. Among other incentives, they won't pay a dime in fuel tax. Looking to head-off that shortfall, several states, including California, Oregon, and Missouri have investigated charging by the mile, instead of by the gallon.

Why not simply base mileage on a vehicle's odometer? Beside the obvious tampering concerns, a state has no right to collect for out-of-state mileage. In the past, it had always been assumed that anyone traveling interstate would eventually need to fill-up with taxable liquid fuel at a regulated pump, thus contributing to each state's highway improvement budget.

Not so, in this modern era. Electric vehicles, like GM's Volt, can be charged from any conventional outlet, or faster via a dedicated higher-voltage charger. Though, theoretically, taxes will be paid on the energy consumed, those taxes don't directly contribute to things like highway improvement.

Now comes the increasingly ever-depreciating GPS with the ability, not only, to collect state and interstate road-usage data with a fair degree of accuracy and tamper-resistance, but also the ability to transmit that data wirelessly on-schedule, on-demand, or even in real-time.

It's that last feature that has many up in arms. How else could this data be used? It could, for instance, report traffic violations to municipalities without involving a law enforcement officer, even as they occur. It could also be used to prove that someone was speeding, or is a habitual speeder, after the fact. Perhaps as evidence in a traffic accident. Or for the purposes of increasing one's insurance premium. It could be used to automatically alert authorities when a suspect returns to their jurisdiction, or to the "scene of the crime". For that matter, it could be used after an incident to locate all individuals who were in the area, and even retrace their path. Spouses could subpoena the data as evidence of infidelity. Ex-spouses could use it to collect child or spousal support.

Some have suggested that such a system would come with built-in privacy mechanisms. For instance, it might only record the mileage in each state, and not specific location data. The biggest problem with that is, now you have no way to audit the accuracy of the figures, or the system as a whole. It presents the possibility of systemic inaccuracies or even gross abuse. In other words, much like electronic voting, how do citizens patrol their government?
