IT Minister Ravi Shankar Prasad had promised action against the agency after Dhoni's wife raised the issue.

A day after former Indian cricket team captain M.S. Dhoni's Aadhaar enrollment form was made public on Twitter, UIDAI blacklisted the operator for 10 years and ordered inquiry into the incident.

"The operator has been blacklisted. He cannot work for UIDAI for 10 years. We are also checking who put the form on social media and action will be taken against them as well," UIDAI CEO Ajay Bhushan Pandey told The Hindu.

Asked if penal action will be taken against those involved, Mr. Pandey said that since Aadhaar has not been generated yet and it is only the form which has been made public, no penal action is being taken at this point.

"But even sharing of the form is wrong. It has personal details, including address. We will be conducting a further enquiry and take action accordingly. All options will be considered," he added.

The incident comes at a time when a Constitutional Bench is hearing whether Aadhaar violates an individual's privacy.

An agency that assists UIDAI to enroll citizens for Aadhaar, on Tuesday, had posted a picture of Dhoni enrolling for Aadhaar along with a photo for his enrollment form.

This was highlighted by his wife Sakshi Singh Rawat in a tweet to IT Minister Ravi Shankar Prasad.

“@rsprasad @CSCegov_ is there any privacy left ??? Information of adhaar card including application is made public property!#disappointed (sic)," she had tweeted.

Mr. Prasad, who is also the Law Minister, had in his reply said, "@SaakshiSRawat Thanks for bringing this to my notice. Sharing personal information is illegal. Serious action will be taken against this."
