A popular WhatsApp messaging app on Tuesday has introduced a new technology called private processing to provide artificial intelligence (AI) in privacy.
“Private processing will allow users to use the powerful additional features of AI-CONSSPERATION, summarize unread messages or editing-editing-mainstream Promises of WhatsApp’s privacy,”-said general With hacker news.
With the introduction of the latest function, the idea is to facilitate the use of AI features, keeping users’ messages in particular. It is expected to be available in the coming weeks.
The opportunity, in a nutshell, allows users to initiate a request for messages using AI in a safe setting called a confidential virtual machine (CVM), so no other side, including Meta and WhatsApp, can access them.
Confidential treatment – one of the three principles underlying function, the rest – this –
- Provided guarantees that force the system to refuse or become publicly expressed if attempts to change confidential guarantees will be identified
- Check transparency that allows users and independent researchers to check the system behavior
- Obsceneity that prevents a particular user to target without breaking all security architecture
- Treatment of statelessness and forward security that ensures that messages are not stored after processing messages so the attacker could not restore historical requests and answers
The system is designed as follows: Private processing gets anonymous credentials to make sure that future requests come from a legal WhatsApp client and then continues to install inattentive http (Ohttp) Connecting between the user’s device and meta-gate using the third relay, which also hides the source IP address from Meta and WhatsApp.
The following is an installed session of a safe application between the user’s device and the conditional execution environment (TeE), after which an encrypted request in the private processing system with an ephemeral key.
It also means that the request cannot be deciphered by anyone, except for a Tee or a user’s device (such as summarizing).
The data is processed in CVM, and the results are sent back to the user’s device in an encrypted format, using the key available only on the device and the private processing server.
Meta also recognized weak connections in the system that could submit it potential attacks with impaired insiders, the risks of supply chain and malicious end users, but emphasized that it took a striking approach to minimize the attack surface.
In addition, the company promised to publish the third CVM binary digestion magazines and CVM binary images to help external researchers “analyze, repeat and report cases where they believe that magazines can trace users’ data.”
Development occurs as meta liberated The dedicated Meta AI app built with Llama 4, which comes with the “social” channel to share and explore the clues and even remix them.
In some ways private processing displays Apple’s approach to confidential processing AI called Private Cloud Compute (PCC), which also directs PCC requests through the Ohttp relay and processes them on Wednesday with sandy.
At the end of last year’s iPhone manufacturer Publicly made available Its virtual research environment PCC (VRE) will allow the research community to check and check the privacy and security guarantees.
