San Francisco, May 15: A data set of over 3 million Facebook users collected via a personality app was available to download freely for anyone for almost four years, New Scientist reported.

The data set was collected via the personality quiz app "myPersonality" by academics at the University of Cambridge.

"The data was highly sensitive, revealing personal details of Facebook users, such as the results of psychological tests.

"It was meant to be stored and shared anonymously, however such poor precautions were taken that deanonymising would not be hard," the report said.

The data sets were controlled by David Stillwell and Michal Kosinski at the University of Cambridge.

"More than 6 million people completed the tests on the myPersonality app and nearly half agreed to share data from their Facebook profiles with the project," said the report.

Alexandr Kogan, at the centre of the British political consultancy firm Cambridge Analytica scandal, was previously part of the project.

"Cambridge Analytica had approached the myPersonality app team in 2013 to get access to the data, but was turned down because of its political ambitions," the report said.

Facebook last month suspended "myPersonality" from its platform, saying the app may have violated its policies.

The social media giant on Monday said that is auditing each and every app that has access to the data of its users and has already suspended 200 apps which failed to comply with its policies.

The company CEO Mark Zuckerberg had promised a thorough investigation and audit into apps that had access to information before Facebook changed its platform policies in 2014 -- significantly reducing the data apps could access.

"To date, thousands of apps have been investigated and around 200 have been suspended -- pending a thorough investigation into whether they did in fact misuse any data," Facebook said.

If Facebook finds evidence that these or other apps did misuse data, it will ban them and notify users via Help Centre on its website.

Appearing before the US Congress in April, Zuckerberg told lawmakers that his own personal data was part of 87 million Facebook users that was improperly shared with Cambridge Analytica.

Bengaluru: Leader of Opposition in the Assembly R. Ashoka has accused the Congress government of using the hijab issue to placate what he described as discontent among minority voters after the Davanagere by-election.

In a post on X on Wednesday, Ashoka alleged that the state government, instead of addressing issues such as price rise, corruption, farmers’ distress and law and order, was attempting to retain its minority vote base by reviving the hijab issue.

Referring to the 2022 dress code introduced by the BJP government, which prohibited hijab in schools and colleges, Ashoka said the Karnataka High Court had upheld the policy and emphasised the importance of discipline in educational institutions.

He questioned the Congress government’s move to revisit the issue and asked whether setting aside the court-backed policy to benefit one community could be described as secularism.

Ashoka further alleged that while the government was willing to permit hijab, it continued to prohibit saffron shawls.

He accused the government of dividing students on religious lines rather than treating schools and colleges as spaces of equality.

Drawing a comparison with Mamata Banerjee’s government in West Bengal, Ashoka claimed that excessive appeasement politics had harmed the state and warned that the Congress in Karnataka could face a similar political response.

He said voters in Karnataka would teach the Congress a lesson for what he termed “vote-bank politics” and for compromising constitutional and judicial principles.
