Contradictheory: A buffet of personal data up for grabs?
It must have been about 25 years ago when I attended a talk about the power of integrating databases, and back then we were lucky governments hadn't quite figured it out yet. But obviously all that has changed now.
The speaker was from Canada, and he illustrated the concept with an example: On one hand, the government struggled to catch welfare recipients who were quietly nipping across the border to work in the United States. On the other hand, it would have been trivially easy to catch them if someone just thought to cross-reference the welfare database with weekday border crossing records.
The technology wasn't the issue. The stumbling block was getting different government departments to cooperate. But while this was an opportunity begging to be taken, the speaker also highlighted the potential dangers: The power inherent in data sharing, when coupled with the reach and authority of national governments, could lend itself to a wide scope of abuses.
Which is precisely what is happening in the United States at the moment. Reports indicate that Elon Musk's Department of Government Efficiency (DOGE) has equipped agents with 'backpacks full of laptops, each with access to different agency systems... to combine databases currently maintained separately by multiple federal agencies'.
Why are they doing this? Because DOGE wants to collate immigration data and cross-reference it with tax records, welfare claims, and even state voting records. According to critics, they allegedly want to target immigrants not just for tracking, but possibly for persuasion, prosecution, and persecution. Civil liberties groups are sounding the alarm, pointing out that this level of cross-agency integration is ripe for abuse.
Truth is, this isn't something new or foreign for Malaysia. Back in 2018, politician Rafizi Ramli openly discussed how his startup, Invoke, was leveraging big data to support the then Opposition candidates. Using electoral roll data, phone polls, and surveys, they constructed detailed voter profiles based on age, postcode, gender, race, and religion to create a 'microtargeting' strategy to identify and win over swing voters with a 40%-60% chance of flipping.
Fast-forward to today, and the government's interest in big data is no secret. From the MyDigital Blueprint to the freshly minted Data Sharing Act 2025, the rhetoric is all about 'digital transformation' and 'evidence-based policymaking'. Then in April, the Malaysian Communications and Multimedia Commission (MCMC) told telcos to hand over mobile network usage data, down to your call records, IP connections, and yes, your location coordinates.
Failure to comply could result in a fine of RM20,000 or up to six months in jail.The official line is that this is for the 'generation of official statistics to support evidence-based policymaking' in the ICT and tourism sector. (Specifically, to identify the number of mobile broadband subscriptions, and to track the number of visitors and 'domestic tourist trips'.)
The government assures us that all data handed over is anonymised and contains no personally identifiable information. But I've learned to be sceptical following alleged breaches that reportedly had data from millions of Malaysians in government databases being sold online.
Now we are to trust the authorities when they say they want the data for policymaking? It's a bit of an overkill, like queuing up for an hour for a free plate of nasi kandar. (Which I have done before.) But why settle for a plate when you could have the whole buffet of personal information data?
A tech news website said what many of us might be thinking: 'What just happened doesn't feel like planning. It feels like surveillance.' Local technologist and computer scientist Dinesh Nair was more colourful, labelling MCMC's explanation as (if I may paraphrase) horse excrement, noting that location data coupled with the time could be used to positively identify individuals.
This isn't theory. We've known for decades how it's possible to do 'data re-identification'. In 1997, MIT computer scientist Latanya Sweeney famously cross-referenced public voter records with anonymised health data to identify then-governor of Massa-chusetts, Bill Weld. She even mailed him his own medical records as proof.
And a few years later, I was reviewing drafts of what would eventually become Malaysia's Personal Data Protection Act (PDPA). While the PDPA was a good step forward in defining personal data rights – like requiring consent and allowing individuals to revoke it – it had one gaping hole: it doesn't apply to government entities. Section 3(1) of the Act explicitly exempts federal and state bodies.
I was told at the time that government departments handled so much data, it would bog them down in red tape to comply. That was the official line. I suspect the unofficial thinking has evolved into: 'Why would we give up control of such a rich treasure trove?'
Fixing this isn't hard. Step one: remove the PDPA exemption for government agencies. Just cross out a paragraph. Step two: appoint an independent oversight body where people can lodge complaints if their rights are violated. The latter's nearly in place, given that the current government has promised an Ombudsman Bill this year that could serve this very function.
At the very least, amending the Act would allow us to point to a breach and say, 'That's illegal', instead of shrugging and saying, 'Well, it's the government. What can you do?'
Because we were warned. We just didn't listen. In his fortnightly column Contradictheory, mathematician-turned-scriptwriter Dzof Azmi explores the theory that logic is the antithesis of emotion but people need both to make sense of life's vagaries and contradictions.

Malaysians Need To Earn Average RM4000 To Introduce GST, Says Anwar
Prime Minister and Finance Minister Datuk Seri Anwar Ibrahim said the reintroduction of the Goods and Services Tax (GST) remains unsuitable for now, citing the rakyat's low income threshold as a key concern. Speaking during the Finance Ministry's monthly assembly, Anwar explained that although GST is recognised as an efficient and transparent taxation mechanism, it imposes a comprehensive financial burden — particularly on low-income earners. 'We postponed (GST) because the income of the people was still too low. My opinion at the time was that people with an income of RM2,000 were still affected although we gave some exemptions,' he said. He highlighted how even though basic necessities such as sugar and rice may be exempt, GST still applies indirectly when people purchase other goods or use public transport. 'It is comprehensive,' he noted. The government, according to Anwar, would only revisit GST implementation when the average household income reaches a more reasonable level — at least RM4,000 a month. 'Let the people's income increase first… maybe at that time we can (implement it). Right now, there are people earning RM1,700 or RM2,000,' he said. For now, the government is focused on a more targeted Sales and Service Tax (SST) system. He said tax revenue collected through SST will be channelled into core public sectors such as education and healthcare. 'The allocation for the Ministry of Education from RM58 billion in 2024 has increased to RM64 billion this year. Similarly, for the Ministry of Health, RM41 billion last year… we are adding RM4 billion to make it RM45 billion,' Anwar said. GST was introduced on Apr 1, 2015, with a standard rate of 6%, but was later repealed on Sept 1, 2018, following widespread criticism over its impact on consumers, particularly those from lower income brackets. It was replaced with the SST system. On 9 June, the government announced a targeted review of the Sales Tax rate and an expanded scope for the Service Tax, effective 1 July, aimed at strengthening Malaysia's fiscal position by increasing revenue while protecting essential goods from new taxes. Stressing the importance of macroeconomic balance, Anwar also acknowledged a gap in policy communication. He urged government members to better explain ongoing fisc Related

GOF foils attempt to smuggle 19,000kg of white rice from Thailand
KOTA BHARU: The General Operations Force (GOF) has foiled an attempt to smuggle 19,000kg of white rice from Thailand along Jalan Kampung Air Gatal, Tanah Merah, as part of the 'Ops Taring Wawasan' operations on Friday (June 20). GOF Southeast Brigade Commander Datuk Nik Ros Azhan Nik Ab Hamid said the seizure was made after a GOF's 9th Battalion team spotted several men loading white sacks into the back of a trailer. "However, all the suspects fled into nearby bushes upon realising the presence of the police," he said in a statement on Saturday (June 21). He said an inspection of the trailer found 19,000kg of white rice, believed to have been smuggled from Thailand and intended for sale on the local market. "The seized rice, along with the trailer, is estimated to be worth RM426,000. The case has been handed over to the Kelantan Paddy and Rice Regulatory Authority for further action," he said, adding that the case is being investigated under Section 20 of the Control of Paddy and Rice Act 1994. Meanwhile, Nik Ros Azhan said that in a separate operation, his team also foiled an attempt to smuggle 11 cows after intercepting a lorry being driven suspiciously in Kampung Telaga Bata, Tumpat, last Thursday (June 19). "An inspection found 11 cows in the back of the lorry, and the driver failed to produce any valid documentation for the livestock. The driver, a 28-year-old local man, was arrested," he said. He added that the total value of the seizure, including the lorry, was estimated at RM151,000. The case has been handed over to the Kelantan Department of Veterinary Services for further action and is being investigated under Section 36(1) of the Animals Act 1953. – Bernama

Retiree loses RM733,300 in online investment scam
GEORGE TOWN: A retired factory worker lost a staggering RM733,300 after falling victim to an online investment scam involving a mobile application known as Falcon PE. The southwest district police headquarters' Commercial Crime Investigation Department received a report from the 66-year-old man on Wednesday. State police chief Datuk Hamzah Ahmad said, based on his report, the scam began in early March, when the victim received a text message from a woman claiming to represent a supposed investment firm, Blue Star AMG. He said the woman promised the victim rapid returns of 10 per cent to 15 per cent within just 20 minutes for any investment made through the Falcon PE app. "Enticed by the high returns, the victim followed the instructions to download the app, register as a user, and begin investing. "Between March 7 and April 24, the victim made 25 money transfers to three different bank accounts, believing they were part of a legitimate investment process. "The scam only became clear when the victim attempted to withdraw profits and was told to make additional payments before the funds could be released," he said in a statement today. Hamzah said, realising he had been scammed, the victim then filed a police report on June 18. The case is being investigated under Section 420 of the Penal Code for cheating. He urged the public to remain vigilant and skeptical of investment schemes promoted online, particularly those promising unusually high or quick returns. The latest incident came less than 48 hours after it was reported that a 47-year-old interior designer lost RM794,000 after being deceived by an online investment scheme known as 'CSECDT,' which was advertised on Facebook.
