UBC Digital

In modern times – in today’s digitised world – data is often compared to gold. But who secures the integrity of today’s gold? Do you have a way of making sure your data wasn’t maliciously changed? Do you know what data is being sold, to whom is it being sold and for how much? Do you get something out of that sale? https://ubc.digital/integrity-in-the-era-of-data/
