Apple, Microsoft, and Google are ushering in a new era of devices enhanced with artificial intelligence. These companies are championing advanced AI-driven smartphones and computers designed to automate tasks such as photo editing and sending personalized messages.

However, these capabilities necessitate greater access to user data.

As AI technology becomes more integrated into our devices, it demands greater access to personal data, raising significant privacy concerns. Apple, Microsoft, and Google are all taking steps to ensure data security, but the effectiveness of these measures remains to be seen. Understanding the full implications of these new AI tools and their data practices is crucial for making informed decisions about their use.

In this new technological landscape, your Windows PC could take frequent screenshots of your activities. An iPhone might consolidate data from various apps, while an Android phone could listen to calls in real-time to identify potential scams.

Privacy Concerns and Data Access

This transition brings significant privacy concerns. To deliver customized services, these companies and their devices require continuous and deeper access to our data. Previously, our interaction with apps and management of files and photos were relatively isolated. AI, however, demands a comprehensive understanding of our activities across apps, websites, and communications, according to security experts.

"Is it safe to share this information with these companies?" asks Bluff Steinhauer, a director at the Public Cybersecurity Coalition, a nonprofit focused on cybersecurity.

Security Risks with AI

The major security risk stems from a subtle change in how these new devices operate. AI's ability to automate complex tasks, like removing unwanted objects from a photo, often requires more computational power than our devices can handle, leading to increased data processing in the cloud.

This data is transmitted to the cloud, a network of servers that handle these requests. Once in the cloud, data can be accessed by others, including company employees, hackers, and government agencies. While some of our data has always been stored in the cloud, our most private data, such as photos, messages, and emails, may now be interconnected and analyzed on company servers.

Tech companies claim they have implemented robust measures to protect user data.

To understand the implications of using AI tools, I investigated the companies' data practices and consulted with security experts. I plan to evaluate the effectiveness of these innovations before deciding whether to share my data.

AI Innovations

Apple has launched Apple Knowledge, a suite of AI services marking its significant entry into the AI race.

These new AI services will be integrated into the latest iPhones, iPads, and Macs starting this fall. Users can automatically remove unwanted objects from photos, summarize web articles, and draft responses to texts and emails. Apple is also enhancing Siri to be more conversational and integrated across apps.

During Apple's presentation, Craig Federighi, the company's senior vice president of software engineering, demonstrated how Apple Knowledge could function. For example, if you receive an email requesting a meeting, your phone can pull up your calendar, relevant documents, and a maps app to determine if you would be late to a play you plan to attend.

Apple aims to process most AI data directly on devices, preventing others, including Apple, from accessing this information. For tasks that require server processing, Apple has developed safeguards such as encrypting data and deleting it promptly.

Apple has also put measures in place to ensure its employees cannot access user data and will allow security researchers to audit its technology to verify these commitments.

However, Apple's approach to deleting user data from servers differentiates it from other companies that retain data. Despite this, Apple has been vague about which new Siri requests might be sent to its servers, noted Matthew Green, a security expert and associate professor of computer science at Johns Hopkins University. Anything leaving your device is inherently less secure, he added.

Apple stated that when Apple Knowledge is released, users will be able to see a report of what requests are processed in the cloud.

AI Advancements

Google has announced a suite of AI services, including a major feature for call security. This AI-powered scam detector listens to calls in real-time and alerts users if the caller seems suspicious, such as asking for a financial PIN. Google stated that this feature, which operates entirely on the phone, does not involve Google listening to the calls.

Google also introduced Ask Photos, a feature that requires sending data to Google's servers. Users can ask questions like "When did my daughter learn to swim?" to find relevant photos. Google mentioned that its workers could, in rare cases, review Ask Photos interactions and photo data to address misuse or harm, and the information could also be used to improve its photos app.

Google's cloud infrastructure is protected with security technologies like encryption and protocols to limit employee access to data. However, Mr. Green, the security expert, expressed concerns about Google's approach to AI privacy, which he found somewhat ambiguous.

AI-Enhanced PCs

Microsoft is integrating AI into traditional PCs with its new line of Windows PCs branded as Copilot+ PC, starting at $1,000. These PCs feature advanced chips and hardware that Microsoft claims will keep user data private and secure. The computers can generate images, rewrite documents, and offer other AI-powered features.

Microsoft also introduced Review, a system designed to help users quickly find documents, emails, or websites they have accessed. Review operates like a visual memory integrated into your PC. Users can type casual phrases to retrieve specific information, such as recalling a video call where someone held a specific coffee cup.

To achieve this, Review takes screenshots every few seconds of what the user is doing and organizes those images into an accessible database. The snapshots are stored and analyzed directly on the PC, meaning the data is not reviewed by Microsoft or used to improve its AI.

Nevertheless, security experts have raised concerns about potential risks, explaining that this data could easily expose everything you’ve ever written or seen if hacked. Consequently, Microsoft has postponed the release of Review indefinitely. The computers come equipped with Microsoft's new Windows 11 operating system, which features multiple layers of security, said David Weston, a company executive overseeing security.
