Q

What is PII?

A

Personally Identifiable Information = any data that could potentially be used to identify a specific individual, especially more so (i.e. “narrowing down” more) than other information. Any information that can be used to distinguish one person from another and can be used for de-anonymising anonymous data can be considered PII.

Q

What PII may people thoughtlessly give away online?

A
  • An email association with our real name
  • Our address when ordering goods on Amazon, eBay, etc.
  • Our bank details: hopefully secure within each bank or shop
  • Our habits – not just shopping but what we search online for may be stored away; health issues, dating agencies
  • Our social groups, our blogs (e.g. the Sarah Palin Yahoo email hack where an attacker obtained access to Palin’s account by looking up biographical details such as her high school and birthdate and using Yahoo!’s account recovery for forgotten passwords)
  • Our Internet Service Provider and technical details about our network

Q

What was the “right to be forgotten” case? What was its outcome?

A

The right to be forgotten is the right to have negative private information about a person to be removed from internet searches and other directories under some circumstances.

People challenged Google to remove data about them that was posted illegally on other websites from their search index. Google cannot be forced to remove “damaging” material from its search engine that was legally posted elsewhere and cannot be considered the “controller” of personal data from other Web sites and therefore should not be responsible for what appears on sites it links to.
