To be sure, the Karnataka government has already hand-stamped and served notices to every resident under quarantine. Was it necessary then to publish sensitive information in the public domain, ask critics. More importantly, does it have legal ground? 

Justice Srikrishna, who helped draft India's data protection Bill, told Chandra R Srikanth of ET NOW that this was a fallout of India not having a data protection law in place. But, even under the privacy law, there are exemptions for extraordinary circumstances, where the government can invoke public safety and order to make these details public. 

The data protection Bill, which has a framework for personal data protection, was introduced in Parliament in December 2019. While the Bill gives citizens control over their personal data, the government can invoke provisions such as national security and other emergencies to exempt agencies from the Bill's purview .

Some legal experts however disagreed with the Karnataka government's move. “At a bare minimum, the state should tell us under what statute they have this power. Even if there is a statutory sanction to it, the exercise now is to be justified on the anvil of necessity. The state ought to show how quarantine stickers or locality level lists are not sufficient to achieve the same objectives, and why it is necessary to publish a state-wide list," said Prasanna S, a practising lawyer based in New Delhi.

Suhrith Parthasarathy, an advocate practicing at the Madras High Court said, "When you disclose the personal information of any person, on the face of it, it is a violation of privacy. Perhaps this might be defensible under the Epidemic Act, but the government will have to tailor such disclosures narrowly. Or it will have to at least pass a specific Ordinance for this purpose. Whatever the legal regime though, the disclosure needs to meet the proportionality test." 

Legal remedies for affected residents appear limited at this juncture. "They can go to the High Court to file a writ petition once this crisis is over, or file a police complaint. A data protection law would have also helped streamline the whole process, from securing consent to publish information to the extent of time they can maintain all of this in the public domain,” Suhrith said. 

While the government may be within its rights to publish details, this may defeat the purpose of keeping names of COVID-19 patients anonymous to protect their privacy, and might endanger those following a quarantine, especially at a time when there is panic and fear of the unknown.

It also raises questions on empathy, as this might lead to more social stigma, at a time when the nation is under lockdown and procuring essentials is becoming difficult.

Kerala, that has more than 100 cases, has been firm about protecting the details of those in quarantine. PB Nooh, the District Collector of Pathanamthitta, tweeted recently about the need to safeguard the privacy of patients undergoing treatment as well as those under self- quarantine.
