Meta has announced that it will soon enable cloud-based processing for artificial intelligence (AI) features on WhatsApp. These new capabilities — including summarising unread messages and providing writing suggestions — will be rolled out while upholding WhatsApp's security and privacy standards, the company said.
To ensure privacy while processing user data on the cloud, Meta has introduced a system called Private Processing. Described as a confidential computing infrastructure, Private Processing allows AI requests to be handled in a protected cloud environment. The system mirrors Apple's Private Cloud Compute (PCC), introduced last year for its Apple Intelligence suite, which processes complex user requests while preserving data privacy.
According to Meta, Private Processing allows AI tools to function securely without exposing personal user data. The system creates a confidential virtual environment in the cloud, ensuring that tasks such as message summarisation and writing suggestions are processed without access to the actual content by Meta or any third party.
Meta outlines the process as follows
When a user requests an AI function — such as summarising chats — WhatsApp sends the request to Meta's cloud servers.
The system verifies that the request is coming from an authentic WhatsApp app on a legitimate device.
The request is then encrypted and anonymised, ensuring Meta cannot identify the user or the origin of the request.
Once the request reaches Meta's servers, it is processed inside a confidential virtual machine (CVM). Meta claims that no one, including the company itself, can view the contents being processed.
The response — such as a message summary — is encrypted and sent back to the user's device. Only the originating device can decrypt and read the result.
Meta states that it does not retain messages after processing is completed.
Meta said it will begin rolling out Private Processing in the coming weeks. The first features to use the system will include AI-generated message summaries and writing suggestions. The company plans to expand the use of this privacy-preserving technology to more AI features in future updates.

KYC fraud explained: What it is and how to stay safe from scams
As digital banking gains popularity in the country, a parallel rise in cyber crimes and financial scams, especially KYC fraud has authorities and banks on high alert. KYC simply means Know Your Customer. The fraud related to KYC basically involves tricking individuals into revealing critical personal or banking information such as OTPs, CVV details, often under the false pretext of account suspension or deactivation. Scammers generally impersonate bank officials and use urgent messages to induce panic. A popular tactic includes SMS alerts such as: "Dear customer, your account will be blocked by 5:30 PM. Update your KYC here: [malicious link]." Now these messages often include suspicious links or force the user to install APK files i.e., Android applications that mimic genuine banking services. Further, once a user clicks on these links and installs the application, it instantly demands unnecessary permissions such as access to your camera, microphone, SMS inbox or contact list allowing fraudsters to steal OTPs, key passwords and even sometimes remotely control your mobile device. Leading banks such as ICICI Bank, Axis Bank and HDFC Bank have reiterated that they never request KYC updates via third party applications or SMS links. They also send periodic warning mails to their customers to be aware of such scams and focus on safeguarding their account details by not sharing any sensitive information with anyone. These fake applications often shared outside of official application stores such as Google Play Store or Apple Store, bypass android security protocols. Then they operate in stealth mode, recording sensitive data, and sometimes even initiate unauthorised or fraudulent transactions. To combat the same institutions such as CERT-In consistently warn mobile users of severe security flaws in Android, Apple, and Chrome. Users must follow the invaluable advice and consistently update their devices on an immediate basis to avoid data theft and system compromise. Ensure that you never click on links in unsolicited messages or install APKs. Never share personal banking details like OTPs, CVVs, or PINs over the phone or through text. Only use official bank applications and websites to verify KYC or other updates. Report suspicious messages to the National Cybercrime Helpline (1930) or If in doubt, never hesitate to contact the respective customer service team of your respective financial institution. You may also report phishing attempts to 'Sanchar Saathi' at or forward them to your bank's fraud reporting email. For example, if you are a customer of ICICI Bank you can email your queries at: antiphishing@ Therefore, staying informed and updated with recent developments in the banking sector along with consistently building knowledge can help you in ensuring financial safety.

US pushes Vietnam to decouple from Chinese tech
The United States is pushing Vietnam in tariff talks to reduce the use of Chinese tech in devices that are assembled in the country before being exported to America, three people briefed on the matter said. Vietnam is home to large manufacturing operations of tech firms such as Apple and Samsung, which often rely on components made in China. Meta and Google also have contractors in Vietnam that produce goods such as virtual reality headsets and smartphones. The Southeast Asian nation has been organising meetings with local businesses to boost the supply of Vietnamese parts, with firms showing willingness to cooperate but also warning they would need time and technology to do so, according to one person with knowledge of the discussions. The Trump administration has threatened Vietnam with crippling tariffs of 46% which could significantly limit access for Vietnam-made goods to their main market and upend the Communist-run country's export-oriented growth model. Vietnam has been asked "to reduce its dependency on Chinese high-tech," said one person familiar with the discussions. "That is part of the restructuring of supply chains and would in turn reduce U.S. dependency on Chinese components," the person added. The ultimate objective is to speed up U.S. decoupling from Chinese high-tech while increasing Vietnam's industrial capacity, a second person said, citing virtual reality devices as an example of Vietnam-assembled products that are too dependent on Chinese technology. All sources declined to be identified as the discussions were confidential. Reuters was not able to learn if the U.S. has proposed numerical targets such as caps on Chinese content for "Made in Vietnam" goods or different tariff rates based on the amount of Chinese content. Apple, Samsung, Meta and Google did not reply to Reuters requests for comment. As the U.S.-imposed deadline of July 8 nears before the tariffs take effect, the timing and scope of a possible deal remain unclear. All sources stressed that while the U.S. has made broader requests for Vietnam to reduce its reliance on China, tackling the issue of Chinese high-tech content in exports was a key priority. Last year, China exported around $44 billion of tech such as electronics components, computers and phones to Vietnam, about 30% of its total exports to the country. Vietnam shipped $33 billion of tech goods to the United States or 28% of the U.S.-bound exports. Both flows are on the rise this year, according to Vietnam's customs data. Vietnam's trade ministry did not reply to Reuters requests for comment. Separate sources have previously said that U.S. demands were seen as "tough" and "difficult" by Vietnamese negotiators. The U.S. also wants Vietnam to crack down on the practice of shipping Chinese goods to America with misleading "Made in Vietnam" labels that draw lower duties - which Vietnam is also trying to heed. The ministry said on Sunday that a third round of talks last week in Washington ended with progress, but critical issues remain unresolved. Vietnam's ruling Communist Party chief To Lam intends to meet U.S. President Donald Trump in the United States, possibly in late June, officials with knowledge of the matter said. No date has been announced for the trip. The White House and Vietnam's foreign ministry did not respond to requests for comment on the possible visit. Not too fast Local firms attending meetings organised by the trade ministry in recent weeks expressed a general willingness to adapt, but many warned that instant changes "would destroy business", according to one of the sources. Vietnam has been slowly developing an industrial ecosystem with local suppliers but it has a long way to go before it can match China's advanced supply chains and cheaper pricing, industry executives say. "Vietnam is about 15-20 years behind China in somewhat fully replicating its supply chain scale and sophistication, but it's catching up fast, especially in key sectors like textiles and electronics," said Carlo Chiandone, a Vietnam-based supply chain expert. Abrupt changes to existing practices may hurt Vietnam's delicate relationship with China, which is both a major investor in its Southeast Asian neighbour and a source of security concerns.
