Personally Identifiable Information(PII)

In News
  • Recently, the Ministry of Corporate Affairs fixed a critical vulnerability in its online portal months after a cybersecurity researcher reported it to the Computer Emergency Response Team of India (CERT-In).
About PII
  • PII is any data or information maintained by an organisation or agency that can potentially be used to identify a specific individual.
  • This could include information such as Aadhaar, PAN, voter identity, passport, date of birth, contact number, communication address, and biometric information.
  • The constituents of PII vary depending on an individual’s home country.
  • However, non-PII in tandem with additional information can be used to identify an individual. Non-PII information includes photographic images (especially of the face or other identifying characteristics), place of birth, religion, geographic indicators, employment information, educational qualifications, and medical records.
  • All this information can be used to identify individuals accurately. And while access to one set of PII may be enough to compromise online security, access to multiple databases can be used to identify and target individuals.
Sensitive & Non- Sensitive PII
  • Nonsensitive PII is publicly available information and can be stored and transmitted unencrypted.
  • This includes information such as zip code, race, gender, and religion. They cannot be used to accurately identify an individual.
  • Sensitive PII, when exposed, can be used to identify individuals and potentially cause harm.
  • Some of the most important components that constitute sensitive PII are stored by employers, government organisations, banks, and other digital accounts used by individuals.
Risks of PII exposure
  • Cyberattacks and weaknesses in digital infrastructure can lead to the exposure of citizens’ PII.
  • Threat actors can gain access to exposed PII and misuse it to launch targeted attacks on individuals.
  • These attacks could range from phishing attacks with messages curated with PII information, to fraudulently opening bank accounts, and siphoning funds from accounts allotted to beneficiaries of government welfare programmes.
  • Threat actors may also use such information to obtain cellular connections, credit cards, and compromise the security of an individual’s digital accounts.
  • Threat actors are also known to sell exposed PII information on the dark web.
Protection of PII
  • Individuals may not be able to prevent leaks in databases of government organisations or service providers. However, they can take steps to ensure that their PII is not readily available to threat actors.
  • Look for HTTPS in URLs when visiting unknown websites.
  • The “S” stands for secure and is used by legitimate websites to secure collected information from unsecured connections. Some browsers may also use a lock symbol in the URL bar to signify that a website is secure.
  • Use a VPN when accessing sensitive information using public networks. A VPN helps protect PII and other vital data by securing your online connection from prying eyes on public networks.
  • Keep a tab on your PII like Aadhaar, passport, PAN, Voter ID, and other important proofs of identity.
  • Avoid sharing or accessing images or details of identity documents through unknown devices.
  • In case you do access them at a photocopy shop or devices owned by others, make sure to delete the documents even from recycle bins to ensure they are not misused.
  • Avoid sharing personal information on social media platforms.
  • In case your PII is leaked, be on the lookout for phishing attacks, that may use leaked information to convince you they are legitimate.
  • Keep a tab on your bank account transactions, credit cards, and credit score; a hit in the score could mean your PII has been misused to procure credit cards in your name.
