1. The definition of PID &NPID

there are two types of data: Personally Identifiable Data (PID) and Non- Personally Identifiable Data (NPID).

Personally Identifiable Data

PID is defined as information that can be used to directly identify an individual. According to the UK Data Protection Act 1998, “Personal Data” is defined as any data that can be used to identify a living individual. The EU’s recently adopted General Data Protection Regulation agrees with this definition, and adds that if anyone could see the data and identify the person with it, it is considered Personally Identifiable information. Examples of this type of data includes name, address, fingerprints, email address, ip address, birthday, posts on social networking websites and telephone numbers.

Woundpro stores following data in cloud server:

– Patient name
– Patient Age
– Cellphone number
– Past medical history – Wound information – Drug use information -…

Non-Personally Identifiable Data

NPID is defined as information that is “anonymous”, meaning that it cannot be used to identify someone. According to the UK Data Protection Act 1998, anonymized or aggregated data is not regulated by the Act, as long as the anonymisation or aggregation is not done in a reversible way. The EU General Data Protection Regulation agrees with this in Article 17.
