The huge private knowledge breach at Coupang reveals that amassing the whole lot “simply in case” is the default, as a result of customers haven’t any sensible option to say no, in accordance with an IT professional Thursday.
This displays a deeper architectural flaw in digital identification methods the place knowledge oversharing is an unavoidable end result of how identification verification is designed, mentioned Javed Khattak, co-founder and chief monetary officer of cheqd, a fee infrastructure agency.
“We don’t know the precise dataset concerned, however in e-commerce it’s widespread to retailer delicate data like full delivery dates when all the corporate wants is an age verify,” he mentioned in an interview with The Korea Occasions.
The sample exists throughout industries. Typically it’s pushed by regulation, however much more typically it’s pushed by advertising, profiling and advice engines, in his view.
“The underlying concern is that the majority firms deal with private knowledge as gasoline for his or her enterprise, leading to an goal to gather as a lot as potential slightly than to attenuate. The most affordable choice is just to retailer the whole lot indefinitely, even when it creates pointless danger.”
Customers additionally lack any mechanism to restrict which items of their identification are revealed as a result of present credentials drive all-or-nothing disclosure, he added. “The answer shouldn’t be rebuilding total methods, however decreasing the quantity of delicate identification knowledge organizations should retailer within the first place.”

Earlier than identification structure, there are operational classes that can not be ignored, the CFO mentioned. “If stories are correct {that a} former worker nonetheless had entry to authentication keys, that displays gaps in off-boarding, key rotation and privilege administration. Massive organizations should deal with these controls as foundational as a result of a single unrevoked credential can expose hundreds of thousands of customers.”
The deeper lesson, in his view, is that even excellent cybersecurity can’t compensate for amassing extra delicate knowledge than essential.
“For governments, the implications are even broader. Centralized digital ID applications that replicate this mannequin danger creating national-scale variations of the identical drawback: One breach exposes the whole lot. Storing each (piece of) identification data doesn’t improve security. It amplifies the implications when one thing goes mistaken. The true takeaway is that knowledge minimization should grow to be a design precept, not an afterthought, as a result of no quantity of safety compensates for amassing an excessive amount of within the first place,” he mentioned.
Additionally problematic is that the majority identification checks rely on government-issued paperwork like passports, driver’s licenses or nationwide IDs that bundle many attributes collectively.
“To show a easy truth resembling being over 18, a consumer nonetheless finally ends up revealing their full delivery date, title, deal with and doc numbers. None of that further data is related to the service. It’s merely a side-effect of how identification paperwork are designed and the way verification workflows, together with storage of proof of such checks, have been constructed round them.”
Minimal-disclosure identification verification is a shift that might scale back huge buyer knowledge breaches, he mentioned. “It means proving a truth, say, ‘I’m over 18’ (or) ‘I dwell on this nation,’ with out revealing anything just like the delivery date. Technically, that is already potential. Zero-knowledge proofs permit one occasion to substantiate an announcement with out exposing underlying knowledge. A number of nationwide digital ID applications and personal sector options are starting to make use of selective disclosure.”
If minimal disclosure had been the default, he added, the Coupang buyer knowledge breach would have uncovered far much less.
“Attackers would entry proofs or tokens as a substitute of uncooked private knowledge. The usability of the stolen data could be dramatically lowered as their misuse may be restricted.”
