Exposing this data publicly may be a huge problem (I don't know enough about the leaks), but in a society where people want the government to offer welfare benefits based on caste (to address historical inequities), the government necessarily needs to track this data to prevent fraud when doling out welfare (eg. to issue the relevant certificates on birth, which can then be used in various benefit schemes analogous to affirmative action). One can't have it both ways!
