>5 days ago, the Norwegian Parliament decided, unanimously, that all
15 citizens of Norway, no matter if they are suspected of something
17 <a href=
"https://www.holderdeord.no/votes/
1430838871e
">required to
18 give fingerprints to the police
</a
> (vote details from Holder de
19 ord). The law make it sound like it will be optional, but in a few
20 years there will be no option any more. The ID will be required to
21 vote, to get a bank account, a bank card, to change address on the
22 post office, to receive an electronic ID or to get a drivers license
23 and many other tasks required to function in Norway. The banks plan
24 to stop providing their own ID on the bank cards when this new
25 national ID is introduced, and the national road authorities plan to
26 change the drivers license to no longer be usable as identity cards.
27 In effect, to function as a citizen in Norway a national ID card will
28 be required, and to get it one need to provide the fingerprints to
31 <p
>In addition to handing the fingerprint to the police (which
32 promised to not make a copy of the fingerprint image at that point in
33 time, but say nothing about doing it later), a picture of the finger
34 print will be stored on the RFID chip, along with a picture of the
35 face and other information about the person. Some of the information
36 will be encrypted, but the encryption will be the same system as
37 currently used in the passports. The codes to decrypt will be
38 available to a lot of government offices and their suppliers around
39 the globe, but for those that do now know anyone in those circles it
41 <a href=

">the
42 encryption is already broken
</a
>. And they
43 <a href=

">can
44 be read from
70 meters away
</a
>. This can be mitigated a bit by
45 keeping it in a Faraday cage (metal box or metal wire container), but
46 one will be required to take it out of there often enough to expose
47 ones private and personal information to a lot of people that have no
48 business getting access to that information.
</p
>
50 <p
>The new Norwegian national IDs are a vehicle for identity theft,
51 and I feel sorry for us all having politicians accepting such invasion
52 of privacy without any objections. So are the Norwegian passports,
53 but it has been possible to function in Norway without those so far.
54 That option is going away with the passing of the new law. In this, I
55 envy the Germans, because for them it is optional how much biometric
56 information is stored in their national ID.
</p
>
58 <p
>And if forced collection of fingerprints was not bad enough, the
59 information collected in the national ID card register can be handed
60 over to foreign intelligence services and police authorities,
"when
61 extradition is not considered disproportionate
".

70 <description><p
>Many years ago, a friend of mine calculated how much it would cost
71 to store the sound of all phone calls in Norway, and came up with the
72 cost of around
20 million NOK (
2.4 mill EUR) for all the calls in a
73 year. I got curious and wondered what the same calculation would look
74 like today. To do so one need an idea of how much data storage is
75 needed for each minute of sound, how many minutes all the calls in
76 Norway sums up to, and the cost of data storage.
</p
>
78 <p
>The
2005 numbers are from
79 <a href=
"http://www.digi.no/analyser/
2005/
10/
04/vi-prater-stadig-mindre-i-roret
">digi.no
</a
>,
80 the
2012 numbers are from
81 <a href=
"http://www.nkom.no/aktuelt/nyheter/fortsatt-vekst-i-det-norske-ekommarkedet
">a
82 NKOM report
</a
>, and I got the
2013 numbers after asking NKOM via
83 email. I was told the numbers for
2014 will be presented May
20th,
84 and decided not to wait for those, as I doubt they will be very
85 different from the numbers from
2013.
</p
>
87 <p
>The amount of data storage per minute sound depend on the wanted
88 quality, and for phone calls it is generally believed that
8 Kbit/s is
89 enough. See for example a
90 <a href=
"http://www.cisco.com/c/en/us/support/docs/voice/voice-quality/
7934-bwidth-consume.html#topic1
">summary
91 on voice quality from Cisco
</a
> for some alternatives.
8 Kbit/s is
60
92 Kbytes/min, and this can be multiplied with the number of call minutes
93 to get the storage requirements.
</p
>
95 <p
>Storage prices varies a lot, depending on speed, backup strategies,
96 availability requirements etc. But a simple way to calculate can be
97 to use the price of a TiB-disk (around
1000 NOK /
120 EUR) and double
98 it to take space, power and redundancy into account. It could be much
99 higher with high speed and good redundancy requirements.
</p
>
101 <p
>But back to the question, What would it cost to store all phone
102 calls in Norway? Not much. Here is a small table showing the
103 estimated cost, which is within the budget constraint of most medium
104 and large organisations:

113 <p
>This is the cost of buying the storage. Maintenance need to be
114 taken into account too, but calculating that is left as an exercise
115 for the reader. But it is obvious to me from those numbers that
116 recording the sound of all phone calls in Norway is not going to be
117 stopped because it is too expensive. I wonder if someone already is
118 collecting the data?
