Check partial plate display against the full staff role, including images and exports, before deciding what the masking achieves.
Partial display can limit casual visibility, but does not establish anonymity. Assess the whole staff role, including images, searches, exports and support access, to understand whether the remaining information can still identify a person.
The last four characters are not necessarily anonymous or unique. A privacy reviewer needs to consider the surrounding context, rather than judging the arrangement from one masked text field on a screen.
A full plate on an attendant's screen makes a visit easy to locate, but also exposes a recognisable identifier. Masked interfaces limit what a viewer initially sees while fuller information can remain elsewhere in the same system.
Presentation and authority to retrieve the underlying record therefore need separate decisions. A shortened label does not explain whether someone can open the source image, search another field or download the complete plate.
A receptionist may only need a session reference. A reviewer correcting a mismatch may need the full plate beside the source image. A neutral reference, limited record access or no individual lookup can be alternatives where the task allows.
The design also needs to avoid ambiguity. Two cars can share the displayed suffix, so partial text should not be treated as a unique way to distinguish visits when a decision depends on the correct vehicle.
A masked text field may sit beside an image thumbnail showing the entire plate. Test search results, evidence views, downloads, notifications and any permitted API together. Define who can reveal full details, for what reason and how that action is reviewed.
Keep masking separate from deletion. A linked account or precise visit time can still allow identification after characters disappear from view. The privacy assessment needs to account for what the role can combine, not just what its first screen displays.
CORE's non-target plate redaction concerns unrelated plates in selected evidence imagery, relevant when sharing evidence without unnecessary bystander identifiers. Aero Ranger also describes role permissions, which are another part of controlling access to records.
Whether staff screens support four-character display, and whether full images remain accessible, needs separate confirmation. The published redaction feature does not establish that particular access tier or the anonymity of the driver.
