The head of Israel's shadowy Shin Bet internal security service said on Tuesday that his agency received Cabinet approval overnight to start deploying its counter-terrorism tech measures to help curb the spread of the new coronavirus in Israel.
While Nadav Argaman acknowledged that using the agency's capabilities on sick Israeli citizens deviates from Shin Bet's typical operations against Palestinian militants, he said the goal was still in line with its overall mission of saving lives.
He vowed there would be stringent oversight to maintain individual privacy and that operatives would only use their findings to warn those that may be exposed to the virus - rather than enforcing any government-mandated quarantine.
"The other state bodies don't have the necessary technological means to aid this effort," Argaman said in a statement. "I am well aware of the sensitivity of this matter and therefore have instructed that only a very limited number of agents will be handling this and the information will not be saved in the Shin Bet database."
The move was announced by Prime Minister Benjamin Netanyahu as part of a series of sweeping measures to step the outbreak and immediately raised concerns from civil-liberties advocates that the practice would raise serious privacy issues.
The final go-ahead also came the day a new Israeli legislature was sworn in following the country's third election in less than a year meaning it bypassed the typically required oversight of a special parliamentary subcommittee.
The new coronavirus has spread to more than 100 countries, infected more than 182,000 people worldwide and killed more than 7,100. For most people, it causes only mild or moderate symptoms, such as fever and cough.
For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia. The vast majority of people recover from the new virus.
More than 300 people have been diagnosed in Israel, with the number quickly rising, triggering fears that fatalities could soon follow as experts predict many more difficult weeks ahead.
Netanyahu acknowledged the technology had never been used before on civilians and would involve a certain degree of violation of privacy. But he said the unprecedented health threat posed by the virus justified its use.
"These means will help us greatly in locating the ill and thus stopping the spread of the virus," he said in a televised announcement late Monday. We will approve these digital tools for a limited period of 30 days. Israel is a democracy and we have to balance individual rights with the greater needs of all.
Among various other measures, Israeli health officials have put out public advisories ordering tens of thousands of people into protective home quarantine.
The new plan looked to use mobile-phone geolocation tracking technology and a review of credit card data to give a far more precise history of an infected person's movements before they were diagnosed and identify people who might have been exposed. Those in jeopardy would then be notified by text message to self-quarantine.
The only other place believed to have used similar technology to fight the coronavirus pandemic is Taiwan, where the government used mobile phones to make sure infected people do not leave their quarantine.
Netanyahu's office insisted the Shin Bet would not be involved in enforcing quarantine orders against sick patients and that all its actions would be shared with health authorities and overseen by legal experts.
Still, the proposal sparked a heated debate over the use of sensitive security technology.
The lead editorial on Tuesday in the liberal Haaretz daily warned that the fight against the new virus in Israel was threatening individual rights.
"The state should not determine the locations of law-abiding citizens, whose only crime is to be infected by the coronavirus," it wrote. "In emergency situations, governments have an even greater responsibility than usual not to violate the checks and balances that are the foundation of the democratic system."
