00:16
So there are a few things
0
16260
2000
Nema puno stvari
00:18
that bring us humans together in the way that an election does.
1
18260
3000
koje nas ljude toliko povezuju kao izbori.
00:21
We stand in elections; we vote in elections;
2
21260
3000
Nudimo se na izborima, glasamo na izborima,
00:24
we observe elections.
3
24260
2000
promatramo izbore.
00:26
Our democracies rely on elections.
4
26260
3000
Naše demokracije počivaju na izborima.
00:29
We all understand why we have elections,
5
29260
3000
Svi razumijemo zašto imamo izbore,
00:32
and we all leave the house on the same day
6
32260
2000
i svi odlazimo iz kuća na isti dan
00:34
to go and vote.
7
34260
2000
i idemo glasati.
00:36
We cherish the opportunity to have our say,
8
36260
3000
Cijenimo mogućnost da kažemo što mislimo,
00:39
to help decide the future of the country.
9
39260
3000
da pomognemo odlučiti budućnost naše zemlje.
00:44
The fundamental idea is that politicians
10
44260
2000
Fundamentalna ideja je ta da političari
00:46
are given mandate to speak for us,
11
46260
3000
dobivaju mandat da govore u naše ime,
00:49
to make decisions on our behalf
12
49260
2000
da za naš račun donose odluke
00:51
that affect us all.
13
51260
2000
koje će utjecati na sve nas.
00:53
Without that mandate, they would be corrupt.
14
53260
3000
Bez tog mandata, bili bi korumpirani.
00:56
Well unfortunately, power corrupts,
15
56260
2000
No, nažalost, moć kvari,
00:58
and so people will do lots of things
16
58260
3000
i stoga će ljudi činiti raznorazne stvari
01:01
to get power and to stay in power,
17
61260
3000
da dobiju moć i zadrže moć,
01:04
including doing bad things to elections.
18
64260
3000
uključujući i loše stvari na izborima.
01:08
You see, even if the idea
19
68260
2000
Vidite, čak i ako je ideja
01:10
of the election is perfect,
20
70260
2000
izbora savršena,
01:12
running a countrywide election is a big project,
21
72260
3000
održati nacionalne izbore je velik projekt,
01:15
and big projects are messy.
22
75260
3000
a veliki projekti su neuredni.
01:18
Whenever there is an election,
23
78260
2000
Gdje god se održavaju izbori,
01:20
it seems like something always goes wrong,
24
80260
2000
čini se da nešto uvijek pođe po krivu,
01:22
someone tries to cheat,
25
82260
2000
netko proba varati,
01:24
or something goes accidentally awry --
26
84260
3000
ili nešto slučajno skrene ustranu --
01:27
a ballot box goes missing here,
27
87260
3000
glasačka kutija nestane ondje,
01:30
chads are left hanging over here.
28
90260
3000
listići su ostali ovdje.
01:33
To make sure as few things as possible go wrong,
29
93260
4000
Kako bismo osigurali da što manje stvari krene po krivu,
01:37
we have all these procedures around the election.
30
97260
3000
donijeli smo sve te procedure u vezi izbora.
01:40
So for example, you come to the polling station,
31
100260
3000
Na primjer, dolazite na glasačko mjesto,
01:43
and a poll station worker asks for your ID
32
103260
3000
i djelatnik tamo vas traži osobnu iskaznicu
01:46
before giving you a ballot form
33
106260
2000
prije nego što vam da glasački listić
01:48
and asking you to go into a voting booth
34
108260
2000
i traži da odete u glasačku kabinu
01:50
to fill out your vote.
35
110260
2000
gdje ćete ispuniti listić.
01:52
When you come back out, you get to drop your vote
36
112260
2000
Kad iziđete, ubacujete svoj glas
01:54
into the ballot box
37
114260
2000
u glasačku kutiju
01:56
where it mixes with all the other votes,
38
116260
2000
gdje se on miješa s ostalim glasovima,
01:58
so that no one knows how you voted.
39
118260
3000
tako da nitko ne zna kako ste vi glasali.
02:01
Well, what I want us to think about for a moment
40
121260
2000
Ono o čemu želim da na trenutak razmislimo
02:03
is what happens after that,
41
123260
2000
je što se događa nakon toga,
02:05
after you drop your vote into the ballot box.
42
125260
2000
nakon što ubacite listić u glasačku kutiju.
02:07
And most people would go home
43
127260
2000
Većina ljudi bi otišla kući
02:09
and feel sure that their vote has been counted,
44
129260
2000
i bila sigurna da je njihov glas zbrojen,
02:11
because they trust
45
131260
2000
jer vjeruju
02:13
that the election system works.
46
133260
2000
da izborni sustav funkcionira.
02:15
They trust that election workers and election observers
47
135260
3000
Oni vjeruju da izborni djelatnici i promatrači
02:18
do their jobs and do their jobs correctly.
48
138260
3000
rade svoj posao i da ga rade pravilno.
02:22
The ballot boxes go to counting places.
49
142260
3000
Glasačke kutije odlaze na mjesta za prebrojavanje glasova.
02:25
They're unsealed and the votes are poured out
50
145260
3000
Ondje se otpečate i listići se istresu
02:28
and laboriously counted.
51
148260
3000
i naporno broje.
02:31
Most of us have to trust
52
151260
2000
Većina nas mora vjerovati
02:33
that that happens correctly for our own vote,
53
153260
2000
da se ovo odvija pravilno kad je naš glas u pitanju,
02:35
and we all have to trust that that happens correctly
54
155260
3000
i svi moramo vjerovati da se sve odvija pravilno
02:38
for all the votes in the election.
55
158260
3000
kad su svi glasovi na izborima u pitanju.
02:41
So we have to trust a lot of people.
56
161260
3000
Znači, moramo vjerovati velikom broju ljudi.
02:45
We have to trust a lot of procedures.
57
165260
3000
Moramo vjerovati velikom broju procedura.
02:49
And sometimes we even have to trust computers.
58
169260
3000
A ponekad čak moramo vjerovati i računalima.
02:54
So imagine hundreds of millions of voters
59
174260
2000
Pa zamislite stotine milijuna glasača
02:56
casting hundreds of millions of votes,
60
176260
2000
kako ubacuju stotine milijuna glasova,
02:58
all to be counted correctly
61
178260
3000
koje sve treba točno izbrojiti
03:01
and all the things that can possibly go wrong
62
181260
3000
i zamislite sve što može poći krivo
03:04
causing all these bad headlines,
63
184260
3000
i prouzročiti sve one loše naslove u novinama.
03:09
and you cannot help but feel exhausted at the idea
64
189260
3000
I ne možete a da se ne iscrpite razmišljajući o ideji
03:12
of trying to make elections better.
65
192260
3000
kako poboljšati izbore.
03:18
Well in the face of all these bad headlines,
66
198260
2000
Suočeni sa svim tim lošim naslovima,
03:20
researchers have taken a step back
67
200260
3000
istraživači su napravili korak unatrag
03:23
and thought about how we can do elections differently.
68
203260
3000
i razmislili o tome kako izbore provesti drugačije.
03:27
They've zoomed out and looked at the big picture.
69
207260
3000
Udaljili su se i pogledali makro aspekt.
03:30
And the big picture is this:
70
210260
2000
A makro aspekt je sljedeći:
03:32
elections should be verifiable.
71
212260
3000
izbori bi morali biti provjerljivi.
03:36
Voters should be able to check
72
216260
3000
Glasači bi morali biti u mogućnosti provjeriti
03:39
that their votes are counted correctly,
73
219260
3000
da su njihovi glasovi točno izbrojani,
03:42
without breaking election secrecy,
74
222260
2000
bez narušavanja tajnosti glasovanja,
03:44
which is so very important.
75
224260
3000
koje je toliko važno.
03:47
And that's the tough part.
76
227260
2000
I to je težak dio.
03:49
How do we make an election system completely verifiable
77
229260
3000
Kako izborni sustav učiniti potpuno provjerljivim,
03:52
while keeping the votes
78
232260
2000
a pritom očuvati glasove
03:54
absolutely secret?
79
234260
2000
apsolutno tajnim?
03:56
Well, the way we've come up with
80
236260
2000
Pa, način do kojeg smo mi došli
03:58
uses computers
81
238260
2000
koristi računala,
04:00
but doesn't depend on them.
82
240260
2000
ali ne ovisi o njima.
04:02
And the secret is the ballot form.
83
242260
2000
A tajna je u glasačkom listiću.
04:04
And if you look closely at these ballot forms,
84
244260
2000
Ako pažljivo pogledate ove glasačke listiće,
04:06
you'll notice that the candidate list
85
246260
2000
primijetit ćete da su kandidati na svakom listiću
04:08
is in a different order on each one.
86
248260
2000
navedeni različitim redoslijedom.
04:10
And that means, if you mark your choices on one of them
87
250260
3000
To znači da, ako označite svoj izbor na jednom od njih
04:13
and then remove the candidate list,
88
253260
2000
i tada uklonite popis kandidata,
04:15
I won't be able to tell from the bit remaining
89
255260
3000
od onoga što je ostalo ja ne mogu znati
04:18
what your vote is for.
90
258260
3000
za koga ste glasali.
04:21
And on each ballot form there is this encrypted value
91
261260
3000
A na svakom listiću postoji enkriptirana vrijednost
04:24
in the form of this 2D barcode
92
264260
2000
u obliku ovog dvodimenzionalnog bar koda
04:26
on the right.
93
266260
2000
s desne strane.
04:28
And there's some complicated cryptography
94
268260
2000
Komplicirana kriptografija
04:30
going on in there,
95
270260
2000
je ovdje na djelu,
04:32
but what's not complicated
96
272260
2000
ali ono što nije komplicirano
04:34
is voting with one of these forms.
97
274260
3000
je samo glasanje pomoću ovih listića.
04:37
So we can let computers do all the complicated cryptography for us,
98
277260
3000
Pa možemo računalima ostaviti da obave svu kompliciranu kriptografiju,
04:40
and then we'll use the paper for verification.
99
280260
3000
a mi ćemo potom koristiti papir za provjeru.
04:44
So this is how you vote.
100
284260
2000
Evo kako glasanje izgleda.
04:46
You get one of these ballot forms at random,
101
286260
4000
Uzmete nasumice jedan od ovih listića,
04:50
and then you go into the voting booth,
102
290260
2000
i ulazite u glasačku kabinu,
04:52
and you mark your choices,
103
292260
2000
označite svoj izbor,
04:54
and you tear along a perforation.
104
294260
3000
i otkinete po perforaciji.
04:59
And you shred the candidate list.
105
299260
3000
Zatim popis kandidata ide u sjeckalicu.
05:02
And the bit that remains, the one with your marks --
106
302260
3000
Dio koji je ostao, dio s vašim oznakama,
05:05
this is your encrypted vote.
107
305260
2000
je vaš šifrirani glas.
05:07
So you let a poll station worker
108
307260
2000
Djelatnik na glasačkom mjestu
05:09
scan your encrypted vote.
109
309260
2000
skenira vaš enkriptirani glas.
05:11
And because it's encrypted,
110
311260
2000
I budući da je enkriptiran,
05:13
it can be submitted, stored
111
313260
2000
može ga se slati, pohraniti
05:15
and counted centrally
112
315260
3000
i brojiti centralno
05:18
and displayed on a website
113
318260
2000
i prikazati na Internet stranici
05:20
for anyone to see, including you.
114
320260
3000
kako bi ga svi mogli vidjeti, uključujući i vas.
05:23
So you take this encrypted vote
115
323260
3000
Vi zatim taj šifrirani glas
05:26
home as your receipt.
116
326260
2000
ponesete kući kao potvrdu.
05:28
And after the close of the election,
117
328260
2000
Nakon zatvaranja glasačkih mjesta,
05:30
you can check that your vote was counted
118
330260
2000
možete provjeriti da je vaš glas zbrojen
05:32
by comparing your receipt
119
332260
3000
uspoređujući vašu potvrdu
05:35
to the vote on the website.
120
335260
3000
s glasom na Internet stranici.
05:39
And remember, the vote is encrypted
121
339260
2000
I zapamtite, glas je šifriran
05:41
from the moment you leave the voting booth,
122
341260
3000
od trenutka kad ste napustili kabinu,
05:44
so if an election official wants to find out how you voted,
123
344260
3000
pa, ako izborni službenik želi otkriti kako ste glasali,
05:47
they will not be able to.
124
347260
2000
neće to moći.
05:49
If the government wants to find out how you voted,
125
349260
2000
Ako vlada želi doznati kako ste glasali,
05:51
they won't be able to.
126
351260
3000
neće to moći.
05:54
No hacker can break in
127
354260
2000
Nijedan haker ne može upasti
05:56
and find out how you voted.
128
356260
2000
i otkriti kako ste glasali.
05:58
No hacker can break in and change your vote,
129
358260
3000
Nijedan haker ne može upasti i promijeniti vaš glas,
06:01
because then it won't match your receipt.
130
361260
3000
jer on tada neće odgovarati vašoj potvrdi.
06:04
Votes can't go missing
131
364260
3000
Glasovi ne mogu nestati,
06:07
because then you won't find yours when you look for it.
132
367260
3000
jer tada nećete pronaći svoj glas kad ga budete potražili.
06:11
But the election magic doesn't stop there.
133
371260
3000
Ali izborna čarolija ne završava ovdje.
06:14
Instead, we want to make the whole process
134
374260
2000
Umjesto toga, mi cijeli proces želimo učiniti
06:16
so transparent
135
376260
2000
tako transparentnim
06:18
that news media and international observers
136
378260
3000
da mediji koji prenose vijesti i međunarodni promatrači
06:21
and anyone who wants to
137
381260
2000
i svatko drugi tko to želi
06:23
can download all the election data
138
383260
2000
može skinuti s Interneta sve izborne podatke
06:25
and do the count themselves.
139
385260
2000
i prebrojiti ih sâm.
06:27
They can check that all the votes were counted correctly.
140
387260
3000
Oni mogu provjeriti da su svi glasovi točno izbrojani.
06:30
They can check
141
390260
2000
Mogu provjeriti
06:32
that the announced result of the election
142
392260
2000
da li je proglašeni rezultat izbora
06:34
is the correct one.
143
394260
2000
onaj pravi.
06:36
And these are elections
144
396260
2000
I to su izbori
06:38
by the people, for the people.
145
398260
2000
od ljudi, za ljude,
06:40
So the next step for our democracies
146
400260
3000
pa su sljedeći korak za naše demokracije
06:43
are transparent
147
403260
2000
transparentni
06:45
and verifiable elections.
148
405260
2000
i provjerljivi izbori.
06:47
Thank you.
149
407260
2000
Hvala vam.
06:49
