*APPLE IBM FACEBOOK ON : *DATA OVERSIGHT*

Apple CEO Timothy Donald Cook

Apple, IBM chiefs call for more data oversight after Facebook breach.

EXECUTIVES from Apple Inc and IBM Corp have called for more oversight on how personal data  is used following the Facebook Inc breach-

That saw roughly 50 million users data misused by consultancy Cambridge Analytica.

Speaking at the three-day China Development Forum in Beijing, Apple chief Tim Cook said  ''well-crafted'' regulation was required, while-

IBM Corp chief  Virginia Rometty said users should have more agency over their own data.

''It's clear to me that something, some large profound change is needed,'' said Apple chief Tim Cook on Saturday.

''I'm personally not a big fan of regulation because sometimes regulation can have unexpected consequences to it, however I think this certain situation is do dire, and -

Has become so large, that probably some ''well-crafted regulation is necessary,'' said Cook, who co-chaired the event this year.

Facebook has come under intense scrutiny from users, lawmakers and investors following allegations from a whistleblower that it allowed British consultancy Cambridge Analytica to improperly use data and build voter profiles that were later used to help elect US President Donald Trump in 2016.

US lawmakers on Friday officially requested that Facebook's Mark Zuckerberg explain at a Congressional hearing how user's data was released to the consultancy.

The breach has sparked intense debate over the responsibility of large tech firms to properly inform users of how their data is used.

''If you are going to use these technologies, you have to tell people you're doing that, and they should never be surprised,'' IBM chief executive Rometty said on Monday. ''{We have to let} people opt in and opt out, and be clear that ownership of the data does belong to the creator,'' said Rometty.

It comes as China, where the forum was held, is also looking to bolster personal policy regulations following a series of missteps by leading tech firms including search firm Baidu and Inc and Alibaba Group Holding Ltd payment affiliate Ant Financial.

China has become increasingly more aware of this problem and have been enforcing the relevant laws more definitely and strongly,'' said Baidu chief Robin Li at the same event on Monday.
