  The awareness and sense of privacy has increased in the minds of people over
the past few years. Earlier, people were not very restrictive in sharing their
personal information, but now they are more cautious in sharing it with
strangers, either in person or online. With such privacy expectations and
attitude of people, it is difficult to embrace the fact that a lot of
information is publicly available on the web. Information portals in the form
of the e-governance websites run by Delhi Government in India provide access to
such PII without any anonymization. Several databases e.g., Voterrolls, Driving
Licence number, MTNL phone directory, PAN card serve as repositories of
personal information of Delhi residents. This large amount of available
personal information can be exploited due to the absence of proper written law
on privacy in India. PII can also be collected from various social networking
sites like Facebook, Twitter, GooglePlus etc. where the users share some
information about them. Since users themselves put this information, it may not
be considered as a privacy breach, but if the information is aggregated, it may
give out much more information resulting in a bigger threat. To bring such
issues to public notice, we developed Open-source Collation of eGovernment data
And Networks (OCEAN), a system where the user enters little information (e.g.
Name) about a person and gets large amount of personal information about him /
her like name, age, address, date of birth, mother's name, father's name, voter
ID, driving licence number, PAN.
