All about WhatsApp
THE WhatsApp announced a new feature that uses artificial intelligence (IA) to help users with Summarize Unadalled Messages quickly and privately. Called Message Summariesthe feature was developed to facilitate the recovery of lost conversations – especially in situations such as unstable connections, travel or excess notifications.
The novelty is fueled by Goal there and focuses on the privacy of the user. According to the company, the content of the messages and the summaries generated are neither accessed by the goal nor by WhatsApp. The function will initially be available only to users in the United States who use the app in English, with expansion plans to other languages and countries by the end of the year.
Private processing protects WhatsApp messaging
The operation of Message Summaries is based on Private Processingwhich allows the system to generate summaries without messages having to get out of the device. With this, processing occurs local, preserving the privacy of the information exchanged in the conversations.
In addition, whatsapp states that No one else on chat is notified When a user uses the summary function. The feature is designed to be discreet, keeping control in the user’s hands.
How Private Processing With IA works on WhatsApp
The resource of Message Summaries WhatsApp is made possible by an infrastructure called Private Processingbased on confidential computing environments that protect users’ messages even from their own goal. The technology was built on a Trusted Execution Environment (TEE)which allows you to process data safely on Confidential Virtual Machines (CVMs), without this information being accessed by third parties – not even by the platform servers.
According to META ENGINEERING BLOGthe system performs several technical steps to ensure this protection. The user’s device authenticate the session and establishes a secure connection with the TEE through protocols as Oblivious http (Ohttp) and Ra-tlshiding the applicant’s IP and verifying if the executed code is in accordance with the audit binaries registered in a public book.
The goal ensures that the data is encrypted from end to end with ephemeral keys, and processing occurs without retention of messages after completion of the task.
Other measures include:
- User traceabilitypreventing the direction of requests to specific machines;
- Verifiable Guaranteesas publication of logs and codes for researchers analysis;
- Security against insiders and physical attackswith software hardning, memory encryption and physical controls on data centers.
Option is deactivated by default
The goal reinforces that the use of Message Summaries is completely. The feature is deactivated by default and can be configured manually. Through options for Advanced Chat Privacythe user can define which conversations can be used for AI functions, such as automatic summaries.
With this initiative, WhatsApp seeks to improve the user experience without compromising the security or confidentiality of information. The company has not yet released a specific date for the global release of functionality.

Security concerns
Despite the guarantees offered by WhatsApp, the use of artificial intelligence to process messages still raises concerns. The main question is in the way data is dealt with and if, in fact, there is no collection of sensitive information during the process of generating summaries.
The promise of Local and private processing It reduces risks, but does not eliminate debate on the transparency of algorithms and the possibility of technical breaches or future changes in privacy policy.
