Data Exhaust and Digital Ownership

By Dr Riaan Steenberg

Every digital action leaves residue. Searches, clicks, unsubscribes,
locations, abandoned forms, old profiles, device identifiers, and
behavioural traces become part of a shadow economy of information.

Waste Is the Wrong Word

We call it waste because it feels incidental. The user has moved on.
The transaction is finished. The account is closed. But the residue may
remain valuable to someone else.

Digital waste can reveal intention, habit, vulnerability, preference,
and timing. That makes it commercially and socially significant.

Ownership Is Blurred

The person created the trace, the platform captured it, the vendor
processed it, and third parties may infer new value from it. Ownership
becomes difficult because the data is relational.

This is why consent forms alone are not enough. People rarely
understand the future uses of the residue they leave behind.

A Better Standard

The better standard is stewardship. Organisations should treat
digital residue as something requiring care, minimisation, expiry,
transparency, and accountability.

If a company benefits from people’s traces, it should also carry
duties toward those people.

The question ‘who owns your digital waste?’ is really a question
about power. In a digital society, invisible residue must not become an
ungoverned asset class.
