Facebook Fingerprinting Photos to Prevent Revenge Porn

This is a pilot project in Australia:

Individuals who have shared intimate, nude or sexual images with partners and are worried that the partner (or ex-partner) might distribute them without their consent can use Messenger to send the images to be “hashed.” This means that the company converts the image into a unique digital fingerprint that can be used to identify and block any attempts to re-upload that same image.

I’m not sure I like this. It doesn’t prevent revenge porn in general; it only prevents the same photos being uploaded to Facebook in particular. And it requires the person to send Facebook copies of all their intimate photos.

Facebook will store these images for a short period of time before deleting them to ensure it is enforcing the policy correctly, the company said.

At least there’s that.

More articles.

EDITED TO ADD: It’s getting worse:

According to a Facebook spokesperson, Facebook workers will have to review full, uncensored versions of nude images first, volunteered by the user, to determine if malicious posts by other users qualify as revenge porn.

Australia Considering New Law Weakening Encryption

News from Australia:

Under the law, internet companies would have the same obligations telephone companies do to help law enforcement agencies, Prime Minister Malcolm Turnbull said. Law enforcement agencies would need warrants to access the communications.

“We’ve got a real problem in that the law enforcement agencies are increasingly unable to find out what terrorists and drug traffickers and pedophile rings are up to because of the very high levels of encryption,” Turnbull told reporters.

“Where we can compel it, we will, but we will need the cooperation from the tech companies,” he added.

Never mind that the law 1) would not achieve the desired results because all the smart “terrorists and drug traffickers and pedophile rings” will simply use a third-party encryption app, and 2) would make everyone else in Australia less secure. But that’s all ground I’ve covered before.

I found this bit amusing:

Asked whether the laws of mathematics behind encryption would trump any new legislation, Mr Turnbull said: “The laws of Australia prevail in Australia, I can assure you of that.

“The laws of mathematics are very commendable but the only law that applies in Australia is the law of Australia.”

Next Turnbull is going to try to legislate that pi = 3.2.

Another article. BoingBoing post.

EDITED TO ADD: More commentary.

Australia Is Testing Virtual Passports

Australia is going to be the first country to have virtual passports. Presumably, the passport data will be in the cloud somewhere, and you’ll access it with an app or a URL or maybe just the passport number.

On the one hand, all a passport needs to be is a pointer into a government database with all the relevant information and biometrics. On the other hand, not all countries have access into all databases. When I enter the US with my US passport, I’m sure no one really needs the paper document—it’s all on the officers’ computers. But when I enter a random country, they don’t have access to the US government database; they need the physical object.

Australia is trialing this with New Zealand. Presumably both countries will have access into each others’ databases.

Australia Outlaws Warrant Canaries

In the US, certain types of warrants can come with gag orders preventing the recipient from disclosing the existence of warrant to anyone else. A warrant canary is basically a legal hack of that prohibition. Instead of saying “I just received a warrant with a gag order,” the potential recipient keeps repeating “I have not received any warrants.” If the recipient stops saying that, the rest of us are supposed to assume that he has been served one.

Lots of organizations maintain them. Personally, I have never believed this trick would work. It relies on the fact that a prohibition against speaking doesn’t prevent someone from not speaking. But courts generally aren’t impressed by this sort of thing, and I can easily imagine a secret warrant that includes a prohibition against triggering the warrant canary. And for all I know, there are right now secret legal proceedings on this very issue.

Australia has sidestepped all of this by outlawing warrant canaries entirely:

Section 182A of the new law says that a person commits an offense if he or she discloses or uses information about “the existence or non-existence of such a [journalist information] warrant.” The penalty upon conviction is two years imprisonment.

Expect that sort of wording in future US surveillance bills, too.

A Real Movie-Plot Threat Contest

The “Australia’s Security Nightmares: The National Security Short Story Competition” is part of Safeguarding Australia 2012.

To aid the national security community in imagining contemporary threats, the Australian Security Research Centre (ASRC) is organising Australia’s Security Nightmares: The National Security Short Story Competition. The competition aims to produce a set of short stories that will contribute to a better conception of possible future threats and help defence, intelligence services, emergency managers, health agencies and other public, private and non-government organisations to be better prepared. The ASRC competition also aims to raise community awareness of national security challenges, and lead to better individual and community resilience.

New, unpublished writers are encouraged to enter the competition.

The first prize is $1000, with the second prize being $500 and third prize being $300.

[…]

Entrants need to write a short story with a security scenario as the story plot line or as the essential backdrop. An Australia context to the story is required, and the story needs to be set between today and 2020. While the story is to be fictional, it needs to be grounded in a plausible, coherent and detailed security situation. Rather than just describing on an avalanche of frightening events, writers are encouraged to focus on the consequences and challenges posed by their scenarios, and tease out what the official and public responses would be. Such stories provide more useful insights for those planning to face security threats.

People who have entered my movie–plot contests should take note; that’s real prize money. I’m working on my own submission: it involves al Qaeda, a comet hitting the earth, zombies, and feral pigs.

(And while we’re on the topic, here’s a video of the 100 greatest movie threats. Not movie-plot threats—threats from actual movies.)

Australian Security Theater

I like the quote at the end of this excerpt:

Aviation officials have questioned the need for such a strong permanent police presence at airports, suggesting they were there simply “to make the government look tough on terror”.

One senior executive said in his experience, the officers were expensive window-dressing.

“When you add the body scanners, the ritual humiliation of old ladies with knitting needles and the farcical air marshals, it all adds up to billions of dollars to prevent what? A politician being called soft on terror, that’s what,” he said.

How did the CIA and FBI Know that Australian Government Computers were Hacked?

Newspapers are reporting that, for about a month, hackers had access to computers “of at least 10 federal ministers including the Prime Minister, Foreign Minister and Defence Minister.”

That’s not much of a surprise. What is odd is the statement that “Australian intelligence agencies were tipped off to the cyber-spy raid by US intelligence officials within the Central Intelligence Agency and the Federal Bureau of Investigation.”

How did the CIA and the FBI know? Did they see some intelligence traffic and assume that those computers were where the stolen e-mails were coming from? Or something else?

Australia Man Receives Reduced Sentence Due to Encryption

From the Courier-Mail:

A man who established a sophisticated network of peepholes and cameras to spy on his flatmates has escaped a jail sentence after police were unable to crack an encryption code on his home computer.

[…]

They found a series of holes drilled in to walls and ceilings throughout the Surfers Paradise apartment with wires leading back to Wyllie’s bedroom.

Police seized his personal computer, but files were encrypted and a video camera was not plugged in.

[…]

In passing sentence, Judge Devereaux took in to account the 33 days Wyllie had spent in custody after being arrested and ordered that two years’ probation was sufficient punishment, given that there was no hard evidence proving he had secretly recorded his flatmates.

Cost/Benefit of Terrorism Security

“The terrifying cost of feeling safer,” from the Sydney Morning Herald:

Sandler and his colleagues conducted an analysis of the costs and benefits of five different approaches to combating terrorism. I must warn you that, because of the dearth of information, this study is even more reliant on assumptions than usual. Even so, in three cases the cost of the action so far exceeds the benefits that doubts about the reliability of the estimates recede.

Because the loss of life is so low, they measure the benefits of successful counter-terrorism measures in terms of loss of gross domestic product avoided. Trouble is, terrorism does little to disrupt economic growth, as even September 11 demonstrated.

Using the case of the US, Sandler estimates that simply continuing the present measures involves costs exceeding benefits by a factor of at least 10. Adopting additional defensive measures (such as stepping up security at valuable targets) would, at best, entail costs 3.5 times the benefits. Taking more pro-active measures (such as invading Afghanistan) would have costs at least eight times the benefits.

According to Sandler, only greater international co-operation, or adopting more sensitive foreign policies to project a more positive image abroad, could produce benefits greater than their (minimal) costs.

What’s that? You don’t care what it costs because no one can put a value on saving a human life? Heard of opportunity cost? Taxpayers’ money we waste on excessive counter-terrorism measures is money we can’t spend reducing the gap between white and indigenous health—or, if that doesn’t appeal, on buying Olympic medals.

The Continuing Cheapening of the Word "Terrorism"

Illegally diverting water is terrorism:

South Australian Premier Mike Rann says the diversion of water from the Paroo River in Queensland is an act of terrorism during a water crisis.

Anonymously threatening people with messages on playing cards, like the Joker in The Dark Knight, is terrorism:

Giles County deputies arrest two county teenagers they say made terroristic threats to people on playing cards.

Investigators say 18-year olds Brian Stafford and Justin Dirico left eight threatening playing cards at the Pearisburg Wal-Mart on Saturday, August 9th. The cards read “9 people will die” and “9 people will suffer” with the date 8-15-08.

A ninth card was found on a car at the Dairy Queen on Sunday, August 10th.

I’ve written about this sort of thing before.

EDITED TO ADD (8/26): In the UK, walking on a bicycle path is terrorism.
