Unique in the Crowd: The privacy bounds of human mobility Scientific Reports volume 3, Article number: 1376 (2013)Makes one feel all warm and fuzzy about the CDC's reassurances, doesn't it? And this study was done TEN years ago.
Abstract
We study fifteen months of human mobility data for one and a half million individuals and find that human mobility traces are highly unique. In fact, in a dataset where the location of an individual is specified hourly and with a spatial resolution equal to that given by the carrier's antennas, four spatio-temporal points are enough to uniquely identify 95% of the individuals. We coarsen the data spatially and temporally to find a formula for the uniqueness of human mobility traces given their resolution and the available outside information. This formula shows that the uniqueness of mobility traces decays approximately as the 1/10 power of their resolution. Hence, even coarse datasets provide little anonymity. These findings represent fundamental constraints to an individual's privacy and have important implications for the design of frameworks and institutions dedicated to protect the privacy of individuals.
"This framework protects each and every one of you, the citizens of Israel. This framework protects Israel as a Jewish and democratic state."He said his framework, if adopted, would constitute a victory for all Israelis. He stressed:
"The proposal is fully obligated to the principles of the Declaration of Independence. It entrenches the independence and autonomy of the judicial system, and entrenches human rights and civil [for all Israelis], men and women alike, including Israel's minorities."He warned that having heard passionate views on the controversy from hundreds of Israelis in recent weeks:
"Those who think that a real civil war, with human lives, is a border we won't cross, have no idea." In Israel's 75th year, the abyss is within touching distance. A civil war is a red line. At any price, and by any means, I won't let it happen.
"I heard real, deep hatred," albeit from "a very small minority of people... I heard from people, from all sides, that, heaven forbid, the idea of blood in the streets no longer shocks them."
"I took 'decisive action' to strengthen the bank as its continues to implement a major overhaul announced last fall. My team and I are resolved to move forward rapidly to deliver a simpler and more focused bank built around client needs."Credit Suisse's shares soared 32% at the open but erased some of those gains to close up 19% in Zurich. The cost of buying insurance against the risk of default by the bank eased back from record highs hit Wednesday.

MR. RUSSERT: The president used his radio address yesterday, and tomorrow in the Rose Garden, to talk about a constitutional amendment to ban gay marriage.
SEN. BIDEN: You know, think about this. The world's going to Hades in a handbasket. We are desperately concerned about the circumstance relating to avian flu — we don't have enough vaccines, we don't have enough police officers — and we're going to debate, the next three weeks, I'm told, gay marriage, a flag amendment, and God only knows what else.
I can't believe the American people can't see through this. We already have a law, the Defense of Marriage Act. We've all voted — not, where I've voted, and others have said, look, marriage is between a man and a woman and states must respect that. Nobody's violated that law, there's been no challenge to that law. Why do we need a constitutional amendment? Marriage is between a man and a woman. What's the game going on here? And now we're going to also vote, right after that, about desecration of the flag. If you can't...
