Is your privacy at risk — or is MCMC just tracking trends? What you need to know about Malaysia's mobile data project
The directive, which reportedly involves mobile call records from the first quarter of this year, was said to be for official statistical purposes.
But how exactly will the data be used — and is your personal information at risk?
Project MPD
The Department of Statistics Malaysia (DoSM), under the Economy Ministry, proposed the use of MPD as a new data source for producing official national statistics.
The proposal was presented to the Cabinet on April 19, 2023, and subsequently approved.
Speaking at a media briefing today, MCMC deputy managing director Datuk Zulkarnain Mohd Yasin said that MPD has been formally recognised by the United Nations as a key big data source for strengthening official statistics.
He said it offers a powerful tool to improve the quality, timeliness, and granularity of national data.
'The global initiative highlights the pressing need to transcend into traditional statistical methods and adopt innovative data solutions, better comprehend and address societal changes while ensuring that privacy and data protection remain paramount at every stage of implementation now,' he added.
Malaysia is not the first to implement the initiative, as countries like Indonesia and Oman have already done so.
In short, instead of relying on surveys conducted every five years, the government plans to use real-time data from MPD to inform policy-making and planning — rather than basing decisions on outdated figures from the last DoSM survey.
What sort of data that MPD will provide to the government?
During the briefing, the media were informed that the MPD project will only collect eight key parameters.
These include the location of signal towers (longitude and latitude), details on local and international mobile subscriptions, and call logs.
The data will provide the government with more accurate, real-time insights to support planning and policy-making, particularly in areas such as economic activity, population movement, and infrastructure needs.
For example, MPD can highlight areas with high mobile activity, helping authorities plan for better telecommunications coverage and capacity, or even identify previously overlooked population areas that were not part of the initial planning.
Zulkarnain shared a personal experience: 'I was stuck in traffic on the highway from Malacca to USJ. My daughter was supposed to have an online meeting with her university team, but she couldn't connect.
'Once the highway was congested, the mobile signal also became overloaded. This shows how people's movement affects not just road traffic but also telecom infrastructure.'
For the ICT sector, MPD enables the production of granular statistics — such as the number of active mobile broadband subscriptions and penetration rates — at multiple administrative levels, including state, district, mukim, parliamentary constituency, state legislative assembly, and local authority areas.
In the tourism sector, the system can generate indicators like the number of visitors and domestic tourism trips.
This allows planners to identify popular destinations, particularly among foreign tourists, and improve services and infrastructure in those areas.
'So from the MPD, we can know for example how many people are visiting the Batu Caves on Monday,' Zulkarnain added.
Will your personal data also be shared?
MCMC commissioner Derek John Fernandez reiterated that mobile users' personal data won't be shared by their respective telcos to the government.
'There's only eight parameters that we want for the data. That does not include a person's identification number, address and others. In fact, we do not want the personal data. In our letter sent to telcos, we told them to 'anonymised or pseudomised' the data when submitting it,' he said.
The eight parameters collected are:
MSISDN – An anonymised subscriber identifier Date and time of transmission Transmitter longitude Transmitter latitude Data type – Such as call detail records, indicating whether it's a regular call or data usage (e.g., WhatsApp) Service type – 3G, 4G, or 5G MCC (Mobile Country Code) – Identifies the country of origin Unique ID
Fernandez clarified that even the location of mobile users will not be shared — only traffic signals from mobile towers will be collected.
There are two ways for telcos to submit MPD data to MCMC:
Option A: Telcos process the data within their own secure environments. Once processing is complete, they submit only anonymised and aggregated outputs, such as the total number of mobile users, to MCMC.
Option B: For telcos without in-house processing capabilities, anonymised data is securely submitted to MCMC for processing.
According to Fernandez, most telcos opt for the first method.
Fernandez assured that MCMC stores all its data on its own premises and does not use cloud services or third-party storage.
When asked why the public was not consulted about the project, Fernandez explained that it is still in its pilot phase.
'We need to complete the pilot test first to get a clearer picture, how effective it is and how it can truly benefit us,' he said.
Cyberjaya has been identified as the first location for the pilot test and will run until 2026.
'This is the new way of survey. The digital way,' Zulkarnain said briefly in a press conference after the briefing.

No prospecting licence issued to Farhash-linked firm, says Sabah land dept
Sabah lands and surveys department director Bernard Liew said allegations claiming that Bumi Suria Sdn Bhd had been awarded a mineral prospecting licence in Sabah are baseless. PETALING JAYA : The Sabah lands and surveys department maintains that no mineral prospecting licence had been issued to Bumi Suria Sdn Bhd, the company linked to businessman Farhash Wafa Salvador Rizal Mubarak. The department's director, Bernard Liew, said no prospecting licence was awarded to the company under the Sabah Mining Ordinance 1960 and that allegations claiming otherwise were baseless. He added that the department was the authoritative body governing mining in the Bornean state. 'Any mineral exploration activity in Sabah can only be conducted after obtaining a legitimate licence issued under Sections 6 and 8 of the Sabah Mining Ordinance. 'And this is subject to technical conditions and other relevant laws that are already in place. The department views seriously any statement made via the media that can mislead the public,' he said in a statement. MalaysiaNow previously reported that Sabah Mineral Management Sdn Bhd (SMM) had awarded Bumi Suria an exploration licence for coal mining. The report said it had been granted exclusive rights to explore and search for minerals on 70,000ha of forest reserve in Kalabakan and Gunung Rara near the Kalimantan border. In a statement to FMT, SMM CEO Natasha Sim said the state government agency was not a licence-awarding body, nor did it have jurisdiction to award or issue licences. On Monday, Farhash said his lawyers had served MalaysiaNow with a cease and desist letter, saying allegations that he owned Bumi Suria and that the company had been awarded a mineral prospecting or exploration licence in Sabah were false and defamatory. The lawyers said Farhash was merely a director and shareholder of Bumi Suria, and demanded that the article be removed from the website and all social media channels.

Kg Sungai Baru redevelopment starts next year, says FT minister
Kampung Sungai Baru's redevelopment was first initiated in 2016, but has been stalled largely due to legal issues, compensation disputes and disagreements among its residents. PETALING JAYA : The long-delayed redevelopment of Kampung Sungai Baru is now expected to begin in the first quarter of 2026, says federal territories minister Dr Zaliha Mustafa. In a written parliamentary reply, she said the project's layout and building plans have been approved, and the developer is currently securing other technical clearances from Kuala Lumpur City Hall (DBKL) and relevant agencies. 'The project is expected to be launched soon, with construction set to begin in the first quarter of 2026,' she said in response to Azman Nasrudin (PN-Padang Serai), who asked for details about the redevelopment. The new timeline marks a delay from a commitment made by Zaliha in 2024, when she told Parliament that construction would begin in the first quarter of 2025. Kampung Sungai Baru's redevelopment was first initiated in 2016, but has been stalled largely due to legal issues, compensation disputes and disagreements among its residents. Zaliha also said that the land acquisition application under the Land Acquisition Act 1960 was submitted by the developer in October 2020 and subsequently approved by the federal territories land working committee. Gazettement of the acquisition, involving 110 properties, including 37 terrace lots, 72 flats, and a Tenaga Nasional Berhad substation, was carried out in June 2021 under Sections 4 and 8 of the Act, for residential and commercial use.

Report on states' competency to enact Islamic laws presented to rulers
Religious affairs minister Na'im Mokhtar said the report was presented to the Conference of Rulers at their 269th meeting last week. (Bernama pic) PETALING JAYA : The findings of a study on the competency of state assemblies to enact Islamic laws under state enactments has been presented to the rulers, says religious affairs minister Na'im Mokhtar. Na'im said the report prepared by a special committee had been presented to the National Council for Islamic Religious Affairs (MKI) chaired by Perak's Sultan Nazrin Shah on July 1. It was also presented to the Conference of Rulers when it held its 269th meeting on July 16, he said in a written parliamentary reply. The report followed studies, discussions and engagements with the various states' head of shariah courts, muftis, Islamic councils as well as representatives from Islamic institutions and other religions. Na'im said the recommendations outlined in the special committee's report will first be studied by the government before further action is taken, partly to look into the need for legal amendments to be tabled in Parliament. 'This is to ensure that every legal amendment enacted, especially those that touches on federal and state jurisdictions, are clear, organised and in line with the Federal Constitution, other laws that are in force, and shariah laws. 'This is to ensure that the amendments are legitimate and will not be questioned by any party once it comes to effect,' he said. The minister said recommendations involving matters under Putrajaya's jurisdiction will first be brought to the Cabinet. Recommendations involving matters under the purview of the respective states are subject to the agreement of the state governments, he added. In August 2023, then MKI chairman Sultan Sharafuddin Idris Shah of Selangor ordered for the special panel to conduct an in-depth study on the competency of state assemblies to enact Islamic laws under state enactments and the jurisdiction of the shariah courts. He said this was due to the number of cases under the jurisdiction of shariah courts being challenged in the Federal Court. In an 8-1 majority decision last year, the Federal Court struck down 16 provisions in the Kelantan Syariah Criminal Code (I) Enactment 2019 on the grounds of their unconstitutionality. Then chief justice Tengku Maimun Tuan Mat said the state assembly had no authority to pass the provisions as part of the enactment, as the offences in question were covered under federal law.
