Apple Auto-opts Everyone Into Having Their Photos Analyzed By AI For Landmarks

Apple’s recent release of Enhanced Visual Search, a feature integrated into its iOS and macOS Photos app, has ignited curiosity and concern. Introduced on October 28, 2024, alongside iOS 18.1 and macOS 15.1, the feature allows users to identify landmarks and points of interest in their images using advanced machine learning and encryption techniques.

Enhanced Visual Search operates by analyzing photos locally on the user’s device through a machine-learning model, identifying potential landmarks. It generates a “vector embedding”—a numerical representation of the landmark—which is encrypted using homomorphic encryption before being sent to Apple’s servers. This advanced encryption ensures that the data remains secure during computations, with neither Apple nor its partner, Cloudflare, able to access the content. Apple also employs differential privacy techniques to anonymize user data while analyzing patterns.

Despite these privacy safeguards, concerns have emerged over the feature’s implementation. Software developer Jeff Johnson, who first highlighted the issue, criticized Apple for failing to communicate the feature’s activation or provide a meaningful opt-in mechanism. In a policy document dated November 18, 2024, Apple stated, “Enhanced Visual Search in Photos allows you to search for photos using landmarks or points of interest. Your device privately matches places in your photos to a global index Apple maintains on our servers.” While the document outlines the technical aspects and reassures users of their data’s security, Johnson argued that the silent activation undermines user choice.

Michael Tsai, another software developer, echoed these concerns, noting that the feature could begin uploading photo metadata even before users are aware of its existence. “Apple is being thoughtful about doing this in a (theoretically) privacy-preserving way, but I don’t think the company is living up to its ideals here,” Tsai observed. He further criticized the system for being less private than Apple’s previously abandoned CSAM scanning initiative, pointing out that Enhanced Visual Search applies to all photos, including those not stored in iCloud.

Matthew Green, a computer science professor at Johns Hopkins, expressed frustration over the timing and lack of transparency. “It’s very frustrating when you learn about a service two days before New Year’s and you find that it’s already been enabled on your phone,” he remarked.

For many critics, the issue lies not in the technical details of the feature—which they acknowledge as innovative—but in Apple’s decision to remove user autonomy by enabling the feature without prior consent.

While no evidence contradicts Apple’s claims about the privacy-preserving nature of the technology, the outcry reveals a deeper unease with how the company deployed it.
