The Maharashtra government has admitted the loss of personal data of about 3 lakh applicants for Aadhaar card, an error that has forced the inconvenience of reapplication on unwitting victims and sparked concerns over possible misuse of the data.3 lakh = 300,000
Containing PAN and biometric information, the data was being uploaded by the state information technology department from Mumbai to the central Bangalore server of the Unique Identification Number Authority of India when it got "lost". "The information is encrypted when uploaded. While the transmission was in progress, the hard disk with the data crashed. When the data was downloaded in Bangalore, it could not be decrypted," said an official from the state IT department, which is overseeing the enrolment of citizens for Unique Identification number (UID) or Aadhaar card. The data mostly belonged to applicants from Mumbai.
That data loss represents a lot of people's time and effort. It will be inconvenient, to say the least, to redo 300,000 enrollments and the data loss has caused some to worry about UID data security.
If the Times of India reporting is accurate though, the data isn't "lost" so much as it is unreadable... by anyone.
