Israel’s cellphone surveillance for coronavirus contact-tracing may have overcome challenges by privacy watchdogs, but the state tracking policy is hard put to deal with easily applied, low-tech evasion methods.
Some Israelis, fearing a quarantine order after unwittingly being near a coronavirus carrier, are rendering themselves untraceable while in public by switching their cellphones to “airplane mode” or using prepaid “burner” SIM cards instead.
Such actions are not illegal and, although there is only anecdotal evidence for their prevalence, they drew remonstration from Communication Minister Yoaz Hendel on Sunday.
“This is a problem,” he told Ynet. “Ultimately, we are not a police state. We will not manage to compel the citizens of the State of Israel to keep to the health regulations.”
The surveillance has been anchored in legislation at the behest of Israel’s Supreme Court after it heard challenges by civil liberties groups who worry the mass-surveillance is ripe for abuse.
Modeled on a counter-terrorism technology and in force since March, the system back-tracks movements of people who have tested positive for the virus to determine who came within 6 feet of them for more than 15 minutes while they were infectious.
Having been identified by their own cellphone locations, these potential new carriers are then ordered over SMS to self-isolate for a period of 14 days from the moment of exposure.
Around 80,000 people per week have received such notifications since July 1, according to officials – an economic drag for a country of 9 million.
Officials say the surveillance has detected some 30% of coronavirus cases in Israel. They also acknowledge a false-positive rate of around 16%, sometimes due to a vertical blind-spot in the technology which risks flagging people above or below a coronavirus carrier in a multi-storey building.
Such instances may be overturned on appeal – a process that can take several days, during which the quarantine is in force.
