As the country, like others, struggles to find a way out of a lockdown that is now entering its second month and has kept a population of 67 million confined to their homes and paralyzed its economy, options that once seemed unfathomable have steadily become more palatable.

“We gave up an absolutely fundamental freedom, that of movement, while most of the Asian countries chose instead to be much more coercive on the individuals,” said Gilles Babinet, vice president of the French Digital Council, a commission that advises the French government.

Mr. Babinet said there was more to learn from Asian democracies, like South Korea, whose use of intrusive digital tracking has helped it avoid imposing the kind of strict lockdowns experienced in Europe.

“You must have a device that is both coercive to those infected and as gentle as possible to the others,” Mr. Babinet said.

So far, many Asian governments have handled the crisis by limiting deaths to a fraction of those suffered in the West. In most cases, that was done not by resorting to debilitating nationwide lockdowns, but rather in part by employing digital tracking, a practice embraced even by strong democracies like South Korea and Taiwan.

In Europe, the possibility conjures up images of China’s authoritarian rulers. An app created by the semi-authoritarian government of Singapore, the longtime proponent of Asian values, is the inspiration for versions being developed by the French, Germans and other Europeans.
