Blockchain technology prevent security loopholes, says an blockchain expert.

“It is unreasonable for a person to have multiple passports,” said Peter Woo, co-founder of Hong Kong Blockchain Society.

Sabrina Meng Wanzhou, the chief financial officer of Huawei Technologies is impossible to hold three valid SAR passports if blockchain technology is applied, Woo said.

He reckoned blockchain as the way out for governments and corporates’ security problems, which applicants’ identity can be verified during the registration process, thus systems’ reliability can be enhanced.

Security of the Immigration Department has been questioned by the society after Meng was found holding three SAR passports and entered Canada with an old one.

Privacy safety is another advantage of blockchain technology, said Woo.

He said blockchain can protected users’ privacy by decentralization, as all data can be stored and accessed by users through user platforms.

“It’s safer, as hackers cannot hack the accounts of all users at the same time,” said Woo.

In contrast, Cathay Pacific leaked the personal data of 9.4 million passengers earlier this year as their database is centralized, said Woo.

He said severs can be attacked by hackers at present situation, without blockchain application on most systems.

While the Electronic Health Record (EHR) Sharing System was established by the government in 2016, Woo said the data should be opened to patients as well.

EHR is now accessible by healthcare professionals with valid registration status, patients are charged with a non-excessive fee if they want to access their data.

Woo said the ‘open data’ concept initiated by the government is not truly implement as the data ownership should be citizens instead of data centraliz
