Comment Epic fail: someone always matches (Score 2, Interesting) 129

This scheme will work for one branch in Lesser Nowhere, Sechwan Province, with a finite and small set of pictures, and a small number of crooks. Once the number of faces increases, the probability of a false positive explodes, roughly as (N 2) (select every two out of N), where N is the size of the pools of pictures + the person being scanned.

The well-known example is the "birthday paradox", in which twenty-three people at a party increases the probability of two of them having the same birthday to fifty-fifty. That particular case was because the actual probability was multiplied by (25 2) = 25! / ((25-2)! * 2!) = 6900 comparisons being made, times 1/365 chances of a hit.

The German federal security service considered using one of my then employer's recognizers for airports to catch terrorists, but ended up facing the problem of accusing grandma of being part of the Bader-Meinhoff gang (;-)) No matter how accurate we were, a few more people in the pool would give us false positives. We'd need roughly an accuracy of 99.9 followed by roughly as many decimal places of 9s as there were powers of ten of people.

Comment Piece of American Culture? (Score 1) 776

tricked into viewing a piece of American culture ruined and rewritten right in front of their very eyes.

.

It's an Australian movie, set in Australia, with Australian actors, Australian Director, Australian Writers.

Piece of co-opted Australian culture... They even drive on the left side of the road - check out IMDb for shots of the yellow interceptors...

Comment It's EU privacy laws (Score 1) 135

EU privacy laws are fairly painful for US companies to comply with. To do business with EU individuals, Personal Identifiable Information needs to be handled according to a set of rules - http://ec.europa.eu/justice/da...

It is often simpler for Amazon deployed companies to set up in the Ireland AWS zone.

As others have mentioned, most foreign SIGINT/COMINT agencies can't gather intelligence domestically, so it lowers barriers. Ironically US companies that want to deal with EU customers may end up moving everything to Ireland. However this allows the NSA to gather intelligence indirectly on US citizens.

A sister company did recruiting, and a then colleague said "I asked for a MVS and Unix person in a particular state with experience in a package", and got hundreds of names, none of whom knew all those things".

Comment Re:It is coming... On Weekends... From Home... (Score 1) 390

If your router enables IPv6, your devices have IPv6 access - no endpoint changes necessary. Current versions of most Operating Systems actually prefer IPv6 but fallback quickly. So it is likely to be turned on transparently.

There is no INTERNAL_IP6_ADDRESS, there is just an IP6_ADDRESS. The firewall blocks or permits dynamically (likely stateful connection management). The /64 subnet that is routed to your network is expected to be routed to the endpoint by your router if needed (modulo firewall rules).

The biggest issue for home networking is the lack of management of the router/firewall itself. You can't port forward (no config UI), you can't permit specific ports in most current home router implementations. However, configuration of ports and so on are not something that the vast majority of users know or care about.

2: Attackers can view your entire IP space. A simple nmap scan, then choosing what zero days to use... instant pwn-ership.

Hmm... Non-direct allocated IP on your subnet, 64 bit subnet, pwn-ership aint that trivial. Scanning a 64-bit address space (AT&T allocates a full /64 to me at home) is going to be pretty obvious at the firewall.

Welcome back to the internet of the early 1990's we all lived on the internet with real IPs, but were protected from firewalls... This whole concept of everyone on a Class C/B/A private subnet thing has only been around for a couple of decades.

Comment Re:IPv6's day will come, but... (Score 2) 390

The main difference tech people will see is that they can't ping an IPv6 address from memory. mDNS (as in xyz.local) will become the only way to access another machine with any sanity.

Monitoring DNS at home, most services are already mixing (with a preference, but quick fallback from IPv6). So I'd say that the major websites are already primarily accessed via IPv6. You won't notice it.

It'll just take years...

Comment It is coming... On Weekends... From Home... (Score 5, Interesting) 390

I have IPV6 at home (took some calls to AT&T Customer Support). I don't have it at work, the migration will probably start small network endpoints (phones (apparently t-mobile has already switch), and home networks).

Link local IPV6 is already fairly broadly available - it's the fe80 prefixed address on your ifconfig output. You should be able to ping other ipv6 addresses on your network (*nix to *nix).

Google's IPv6 stats page indicates this too... https://www.google.com/intl/en... has a peculiar comb effect for the last few years. Zooming in seems to give a bit more insight. Google's count of IPv6 connections has a full 1% swing over the weekends vs the week days. Due to IPv6's addressing method, each unique device on your network appears as a unique device on the internet, vs the NATed IPv4 that we all know and love. This would also have an accelerating increase in the number of unique IPs that are visible on the weekend. I know I use more devices over the weekend (chromebook, phone, laptop, table) vs during the week.

Open to other insights, but our homes will be likely IPv6 before our offices are. (Of course aggressive tech companies like google and facebook are likely already IPv6).
