de-identified

De-identified means that data is in a state in which personal identifiers have been removed or obscured so that the person it relates to cannot reasonably be identified directly or indirectly from it.

In plain English

Names and other details that point to a specific person have been taken out or masked. What remains is data that is not reasonably linkable back to that person, either on its own or through indirect connection.

In context

Here, de-identified indicates that the data has had identifying details removed or obscured so the person it concerns cannot reasonably be identified from the remaining information, directly or indirectly.

Situation
Understanding encryption, privacy, data-sharing, and secure-connection labels
What it communicates
describes data after direct identifying details have been removed

Meaning limits

The term alone does not mean identification is absolutely impossible; it means the person cannot reasonably be identified from the data.

Examples

“The council published de-identified complaint records, showing age bands and districts instead of names, full postcodes, and exact birth dates.”

Core meaning

“The interview transcripts remained de-identified, with each speaker marked only as A, B, or C.”
