Crypto and Privacy Links
The privacy links are for nostalgia buffs
(but not anymore, since some degree of privacy is now possible).
New links are added to the top of the list.

The T.S.A. also maintains a PreCheck disqualification list, tracking people accused of violating security regulations, including disputes with checkpoint or airline staff members. Much of this personal data is widely shared within the Department of Homeland Security and with other government agencies ... and in some cases, [with] private companies for purposes unrelated to security or travel."

"The National Security Agency has obtained direct access to the systems of Google, Facebook, Apple and other US internet giants, according to a top secret document obtained by the Guardian. The NSA access is part of a previously undisclosed program called PRISM, which allows officials to collect material including search history, the content of emails, file transfers and live chats, the document says."

"The National Security Agency is currently collecting the telephone records of millions of US customers of Verizon, one of America's largest telecoms providers, under a top secret court order issued in April. ... Under the terms of the blanket order, the numbers of both parties on a call are handed over, as is location data, call duration, unique identifiers, and the time and duration of all calls. The contents of the conversation itself are not covered."
But at the very least they can know who you're calling and they can track your movements. Whenever you switch on your cellphone they know instantly where you are.
- Data Leak Shakes Notion of Secret Offshore Havens and, Possibly, Nerves
"[Some rich people who hide their money to avoid paying taxes on it] are suddenly very anxious after the leak of 2.5 million files detailing the offshore bank accounts and shell companies of wealthy individuals and tax-averse companies. ... [The] the enormous size of the data dump obtained by the International Consortium of Investigative Journalists ... has punched a big hole in the secrecy that surrounds what the Tax Justice Network estimates are assets worth at least $21 trillion held in offshore havens.

- Peter Lee: US digs in for cyber warfare
"In the United States, providing government law enforcement with back-door access to networks, aka 'lawful intercept', is a legal requirement for digital telecom, broadband Internet, and voice-over-IP service and equipment providers under the CALEA (Communications Assistance to Law Enforcement Act) law. The Federal Bureau of Investigation (FBI) is currently lobbying the US administration and the Federal Communications Commission to require that social-media providers such as Facebook provide similar access so that chats and instant messaging can also be monitored in real time or extracted from digital storage."
- Australia Moves to Massively Expand Internet Surveillance
"The Australian government has proposed sweeping changes to its surveillance and national security laws. The government's wish list includes mandatory data retention, surveillance of social networks, criminalization of encryption, and lower thresholds for warrants."
Under the guise of expanding "the fight against terrorism" the Australian spooks wish to "establish an offence for failure to assist in the decryption of communications". So if you have some proprietary commercial information which you encrypt and send in a file to a colleague, and if you refuse a request by the Australian government to allow them to decrypt that file, then you can be charged with the commission of a crime (proposed penalty as yet unstated but could be imprisonment).
- Senate panel criticizes anti-terrorism data-sharing centers
"A federal domestic security effort to help state and local law enforcement catch terrorists by setting up more than 70 information-sharing centers around the country has threatened civil liberties while doing little to combat terrorism, a two-year examination by a Senate subcommittee found."

- Chris Crum: Social Discovery is BIG (and Creepy?) at SXSW"There's a new trend in social media and application development, and it's called ‘social discovery’."
The one thing social networking is NOT about, is “giving” people opportunities to connect better, unless that means better opportunity for exposure to product and data gathering by government. Once upon a time there were phone calls and actual face to face connecting. And then along came email which made it possible to connect quickly and cheaply with those who were far away and did that very well actually but unfortunately there was no place for marketing in private email exchanges so email had to be replaced.
Here’s my stand, I choose NO, so I don’t do Facebook, Twitter or any online social networking site because I know what the true purpose is, i.e., harvesting target info. I discourage my clients from this as well. Amazingly I survive quite well without being “connected” or “liked” and I am quite sure there is plenty of information about me available anyway. I’m such a relic I do my interacting the old fashioned way with people I have intimate relationships; I communicate one on one, face to face, by phone and the now archaic tool of email. There is no substitute for this kind of interaction with humans. None. It seems to me that the more knowledge has increased, the more information we have, the less we really know because not only has the human touch thing been circumvented by digital technology, humanity itself is now systematically being counterfeited with a shallow reproduction. We are becoming programed holograms. The real deal, that unique part of humanity that has always been delightfully serendipitous, has now been replaced with a robotic, predictable, never allowed to step sideways, soul-less clone that lives for, acts and reacts, and by default witlessly worships, the god of commerce.

- Recording Everything: Digital Storage as an Enabler of Authoritarian Governments
"[Soon] it will become technologically and financially feasible for authoritarian governments to record nearly everything that is said or done within their borders — every phone conversation, electronic message, social media interaction, the movements of nearly every person and vehicle, and video from every street corner. Governments with a history of using all of the tools at their disposal to track and monitor their citizens will undoubtedly make full use of this capability once it becomes available."
- Carrier IQ Withdraws Legal Threat Against Security Researcher
"[Security researcher Trevor] Eckhart said he'd discovered Carrier IQ's software secretly monitoring “many U.S. handsets sold on Sprint, Verizon, and more.” He estimated that it was running on more than 141 million handsets. Furthermore, as installed by carriers, the software oftentimes couldn't be removed, or could be removed only by advanced users willing to root their phones."
- Can the [U.S.] government take away my laptop?
"Federal Customs and Border Patrol agents have the [legal] right [according to the 9th Circuit Court in San Francisco] to confiscate and examine electronic devices belonging to anyone entering the United States. The agents aren't required to have probable cause before searching someone's devices. And they can look for any evidence of any crime at all."
- Tighter oversight on border laptop searches
"The procedures also allowed border agents to retain documents and devices for 'a reasonable period of time' to perform a thorough search 'on-site or at an off-site location.'"
So if you enter the U.S. with a laptop you can expect federal agents to look through your personal files and maybe even take your laptop away for a few hours or days and perhaps even copy the entire hard drive. Better to stay far away.
- Digital Due Process — Modernizing surveillance laws for the digital age
"The Electronic Communications Privacy Act ... is a patchwork of confusing standards that have been interpreted inconsistently by the courts, creating uncertainty for both service providers and law enforcement agencies. ECPA can no longer be applied in a clear and consistent way, and, consequently, the vast amount of personal information generated by today's digital communication services may no longer be adequately protected."

- Chapter 8, Signals Intelligence, from Jeffrey T. Richelson's The U.S. Intelligence Community
"Another reconnaissance project involving submarines ... involved implanting a device to intercept the signals transmitted along a Soviet underwater cable in the Sea of Okhotsk, between the Kamchatka Peninsula and the eastern Soviet coastline. A combined Navy-NSA team, operating from a submarine, installed a miniaturized waterproof eavesdropping device — a large tape pod that fit over the Soviet cable, through which key Soviet military and other communications flowed. The pod had a wraparound attachment that intercepted the cable traffic by "induction" ... The Sea of Okhotsk operation continued until 1981, when former NSA employee Ronald Pelton sold the Soviets information about the operation."

"Without any official public notice, and without any congressional hearings, the Bush administration — with an initial appropriation of $200 million — is constructing the Total Information Awareness System. It will extensively mine government and commercial data banks, enabling the FBI, the CIA, and other intelligence agencies to collect information that will allow the government ... 'to essentially reconstruct the movements of citizens.' This will be done without warrants from courts, thereby making individual privacy as obsolete as the sauropods of the Mesozoic era."
- Identity-based Internet idea shelved [webpage (re)moved]
"[A] Pentagon research agency ... considered but rejected ... tagging Internet data with unique personal markers to prevent anonymous use of some parts of the Internet. ... The plan, known as eDNA ... would have divided the Internet into secure 'public network highways' where a user would need to be identified, and 'private network alleyways' which do not require identification. ... [The proposal] read in part: 'We envisage that all network and client resources will maintain traces of user eDNA so that the user can be uniquely identified as having visited a Web site, having started a process or having sent a packet. 'This way, the resources and those who use them form a virtual 'crime scene' that contains evidence about the identity of the users, much the same way as a real crime scene contains DNA traces of people.'"
So it seems that, for the authors of this proposal, accessing a website, or using the internet for any purpose at all, makes one a virtual criminal. What will they think of next?

The massive deployment of key-recovery-based infrastructures to meet law enforcement's specifications will require significant sacrifices in security and convenience and substantially increased costs to all users of encryption. Furthermore, building the secure infrastructure of the breathtaking scale and complexity that would be required for such a scheme is beyond the experience and current competency of the field, and may well introduce ultimately unacceptable risks and costs".
