KUALA LUMPUR (Jan 11): The Covid-19 vaccination certificate in the MySejahtera application cannot be duplicated because it uses blockchain technology, which guarantees its authenticity, said Minister of Science, Technology and Innovation (MOSTI), Datuk Seri Dr Adham Baba. However, he said that the recent forgery of vaccine certificates in Terengganu was due to integrity problems of irresponsible parties. On Monday, Terengganu police arrested a doctor at a private clinic, after he was suspected of issuing fake Covid-19 vaccination certificates in Marang. He added that the latest blockchain technology was safe and protected the public's personal data, and the authenticity of the Covid-19 vaccination certificate could not be doubted. “With the e-Skrol system that uses blockchain technology, MOSTI believes that employers’ confidence in graduates can be enhanced, especially for the recruitment of employees in their respective organisations and companies,” he said.
