When information hit this week that West Virginian army members serving overseas will turn into the primary individuals to vote by telephone in a serious US election this November, safety consultants have been dismayed. For years, they’ve warned that each one types of on-line voting are significantly weak to assaults, and with indicators that the midterm elections are already being focused, they fear that is precisely the incorrect time to roll out a brand new methodology. Specialists who spoke to WIRED doubt that Voatz, the Boston-based startup whose app will run the West Virginia cellular voting, has discovered learn how to safe on-line voting when nobody else has. On the very least, they’re involved in regards to the lack of transparency.
“From what is available publicly about this app, it’s no different from sending voting materials over the internet,” says Marian Schneider, president of the nonpartisan advocacy group Verified Voting. “So that means that all the built-in vulnerability of doing the voting transactions over the internet is present.”
And there are a number of vulnerabilities relating to voting over the web. The system an individual is utilizing may very well be compromised by malware. Or their browser may very well be compromised. In lots of on-line voting techniques, voters obtain a hyperlink to a web based portal in an electronic mail from their election officers—a hyperlink that may very well be spoofed to redirect to a distinct web site. There’s additionally the danger that somebody might impersonate the voter. The servers that on-line voting techniques depend on might themselves be focused by viruses to tamper with votes or by DDoS assaults to carry down the entire system. Crucially, digital votes don’t create the paper path that permits officers to audit elections after the very fact, or to function a backup if there may be the truth is tampering.
However the factor is, individuals need to vote by telephone. In a 2016 Shopper Studies survey of three,649 voting-age Individuals, 33 p.c of respondents stated that they might be extra prone to vote if they might do it from an internet-connected system like a smartphone. (Whether or not it might really enhance voter turnout is unclear; a 2014 report carried out by an unbiased panel on web voting in British Columbia concludes that, when all elements are thought of, on-line voting doesn’t really lead extra individuals to vote.)
Thirty-one states and Washington, DC, already enable sure individuals, principally service members overseas, to file absentee ballots on-line, in line with Verified Voting. However in 28 of these states—together with Alaska, the place any registered voter can vote on-line—on-line voters should waive their proper to a secret poll, underscoring one other main threat that safety consultants fear about with on-line voting: that it could possibly’t shield voter privateness.
“Because of current technological limitations, and the unique challenges of running public elections, it is impossible to maintain separation of voters’ identities from their votes when Internet voting is used,” concludes a 2016 joint report from Frequent Trigger, Verified Voting, and the Digital Privateness Data Middle. That is true whether or not these votes have been logged by electronic mail, fax, or a web based portal.
Voatz says it’s totally different. The 12-person startup, which raised $2.2 million in enterprise capital in January, has labored on dozens of pilot elections, together with primaries in two West Virginia counties this Might. On an internet site FAQ, it notes, “There are several important differences between traditional Internet voting and the West Virginia pilot—mainly, security.”
Voatz CEO Nimit Sawhney says the app has two options that make it safer than different types of on-line voting: the biometrics it makes use of to authenticate a voter and the blockchain ledger the place it shops the votes.
The biometrics half happens when a voter authenticates their identification utilizing a fingerprint scan on their telephones. The app works solely on sure Androids and up to date iPhones with that function. Voters should additionally add a photograph of an official ID—which Sawhney says Voatz verifies by scanning their barcodes—and a video selfie, which Voatz will match to the ID utilizing facial-recognition expertise. (“You have to move your face and blink your eyes to make sure you are not taking a video of somebody else or taking a picture of a picture,” Sawhney says.) It’s as much as election officers to determine whether or not a voter ought to should add a brand new selfie or fingerprint scan every time they entry the app or simply the primary time.
“We feel like that extra level of anonymization on the phone and on the network makes it really really hard to reverse-engineer.”

The blockchain is available in after the votes are entered. “The network then verifies it—there’s a whole bunch of checks—then adds it to the blockchain, where it stays in a lockbox until election night,” Sawhney says. Voatz makes use of a permissioned blockchain, which is run by a particular group of individuals with granted entry, versus a public blockchain like Bitcoin. And to ensure that election officers to entry the votes on election night time, they want Voatz handy ship them the cryptographic keys.
Sawhney says that election officers print out a duplicate of every vote as soon as they entry them, with the intention to do an audit. He additionally tells WIRED that within the model of the app that individuals will use in November, Voatz will add a means for voters to take a screenshot of their vote and have that individually despatched to election officers for a secondary audit.
To deal with considerations about poll secrecy, Sawhney says Voatz deletes all private identification knowledge from its servers, assigns every particular person a novel however nameless identifier inside the system, and employs a mixture of community encryption strategies. “We feel like that extra level of anonymization on the phone and on the network makes it really really hard to reverse-engineer,” he says.
Specialists Are Involved
Little or no info is publicly accessible in regards to the technical structure behind the Voatz app. The corporate says it has performed a safety audit with three third-party safety corporations, however the outcomes of that audit will not be public. Sawhney says the audit comprises proprietary and safety info that may’t leak to the general public. He invited any safety researchers who need to see the audit to return to Boston and examine it in Voatz’s safe room after signing an NDA.
This lack of transparency worries individuals who’ve been finding out voting safety for a very long time. “In over a decade, multiple studies by the top experts in the field have concluded that internet voting cannot be made secure with current technology. VOATZ claims to have done something that is not doable with current technology, but WON’T TELL US HOW,” writes Stanford pc scientist and Verified Voting founder David Dill in an electronic mail to WIRED.
Voatz shared one white paper with WIRED, but it surely lacks the form of info consultants may anticipate—particulars on the system structure, risk assessments, how the system responds to particular assaults, verification from third events. “In my opinion, anybody purporting to have securely and robustly applied blockchain technology to voting should have prepared a detailed analysis of how their system would respond to a long list of known threats that voting systems must respond to, and should have made their analysis public,” Carnegie Mellon pc scientist David Eckhardt wrote in an electronic mail.
Ideally, consultants say, Voatz would have held a public testing interval of its app earlier than deploying it in a reside election. Again in 2010, for instance, Washington, DC, was creating an open-source system for on-line voting and invited the general public to attempt to hack the system in a mock trial. Researchers from the College of Michigan have been capable of compromise the election server in 48 hours and alter all of the vote tallies, in line with their report afterward. Additionally they discovered proof of overseas operatives already within the DC election server. This type of testing is now thought of greatest apply for any on-line voting implementation, in line with Eckhardt. Voatz’s trials have been in actual primaries.
“West Virginia is handing over its votes to a mystery box.”

Voatz’s use of blockchain itself doesn’t encourage safety consultants, both, who dismissed it principally as advertising. When requested for his ideas on Voatz’s blockchain expertise, College of Michigan pc scientist Alex Halderman, who was a part of the group that threat-tested the DC voting portal in 2010, despatched WIRED a current XKCD cartoon about voting software program. Within the final panel, a stick determine with a microphone tells two software program engineers, “They say they’ve fixed it with something called ‘blockchain.’” The engineers’ response? “Aaaaa!!!” “Whatever they’ve sold you, don’t touch it.” “Bury it in the desert.” “Wear gloves.”
“Voting from an app on a mobile phone is as bad an idea as voting online from a computer,” says Avi Rubin, technical director of the Data Safety Institute at Johns Hopkins, who has studied digital voting techniques since 1997. “The truth that somebody is throwing across the blockchain buzzword does nothing to make this safer. That is as dangerous an thought as there may be.”
Blockchain has its personal limitations, and it’s removed from an ideal safety resolution for one thing like voting. Initially, info may be manipulated earlier than it enters the chain. “In fact, there is an entire industry in viruses to manipulate cryptocurrency transactions before they enter the blockchain, and there is nothing to prevent the use of similar viruses to change the vote,” says Poorvi Vora, a pc scientist and election safety knowledgeable at George Washington College.
She provides that if the blockchain is a permissioned model, as Voatz’s is, “It is possible for those maintaining the blockchain to collude to change the data, as well as to introduce denial of service type attacks.”
Sawhney pushes again in opposition to this final critique, telling WIRED that the blockchain verifiers within the Voatz system is a set of vetted stakeholders equivalent to Voatz itself, election officers, nonprofit voting auditors, and politicians.
And despite the fact that the transaction is thru an app moderately than a browser, Vora says beforehand recognized dangers of web voting stay. “Both the browser and the app run on the operating system underneath, and both, hence, inherit the vulnerabilities that go with relying entirely on software,” she says.
Sawhney admits the priority about malware on an individual’s system is respectable however thinks that making a program to control votes could be so arduous as to be impractical. “It’s theoretically possible, if that malware had been specifically written to intercept votes passing, to reverse-engineer our application, break all our keys, specifically modify if somebody marks oval A change it to oval B, and then bypass the identifier and send it to the network, but that is so, so hard to do in real time,” he says. “It is possible, but we haven’t found a way to do it.” He provides that the app checks the telephone for malware earlier than downloading on a tool, although he admits it may very well be doable for malware to go undetected.
The position of facial recognition in authenticating voter identities is one other factor that considerations consultants. Schneider worries that there may very well be methods to trick that expertise utilizing movies accessible elsewhere on the web, as an illustration. And Vora notes that facial-recognition expertise has identified racial biases that would have an effect on who even is ready to entry Voatz.
Sawhney tells WIRED that Voatz has individuals manually test the facial-recognition authorization. That is doable for the time being however might turn into a difficulty if the expertise have been to be launched to a wider citizens, as Voatz states on its web site is the final word purpose. In reality, Voatz has already encountered a scaling downside. When Utah GOP voters tried to make use of the app throughout their caucus in April, many couldn’t get it to work. You may examine many citizens’ expertise in dangerous critiques of Voatz they left in Apple’s App Retailer. Sawhney tells WIRED that the problems stemmed from voters making an attempt to obtain the app and authenticate themselves minutes earlier than polls closed, which didn’t give Voatz sufficient time.
Although Voatz has solutions for a lot of the criticism it has confronted this week, none of its responses are prone to persuade safety consultants that the smartphone voting app is prepared for November. On the very least, the safety world’s response to Voatz underscores how vital transparency is within the rollout of any new voting system. “West Virginia is handing over its votes to a mystery box,” Dill says.
However election officers in West Virginia are enthusiastic in regards to the app. “They used it in the primary in a couple of the other counties to do a test drive, and they said it was wonderful,” says Kanawha County Clerk Vera McCormick, who oversees voting within the state capital of Charleston and plans to permit the 60 abroad army members registered in her county to make use of Voatz to vote. “We’re excited and my understanding is the security is wonderful, so we’ll find out.”
