Apple's Default Enabling of "Enhanced Visual Search" in iOS 18 and macOS 15 Sequoia Raises Privacy Concerns

On December 28, 2023, developer Jeff Johnson published a blog post revealing that Apple's upcoming iOS 18 and macOS 15 Sequoia operating systems will enable "Enhanced Visual Search" (EVS) by default. This has sparked significant user concern regarding privacy and security. The feature transmits user photo data to Apple, directly contradicting Apple's marketing slogan, "What happens on your iPhone, stays on your iPhone," and causing widespread controversy.

To understand the core of the controversy, it's crucial to understand EVS's predecessor, Visual Look Up (VLU). Introduced with iOS 15, VLU identifies elements within photos and provides related information. For example, it can identify a dog breed from a photo, explain the meaning of a car indicator light, or interpret symbols on a clothing label. While convenient, VLU requires Apple to access and process user photo data.

EVS, an enhanced version of VLU, offers more powerful search capabilities. The EVS toggle is located in Settings > Apps > Photos > (at the bottom), and is enabled by default. Apple's official description states: "Allows this device to privately match locations in your photos to a global index maintained by Apple so you can search by almost any landmark or place of interest." This implies that location data from user photos is uploaded to Apple's servers for matching and indexing.

Johnson strongly criticizes Apple's decision to enable EVS by default, arguing it disregards user privacy choices and constitutes a lack of respect. He points out that sending user data to the device manufacturer means users no longer have complete control over their privacy. This resonates with growing user concerns about data privacy and security, sparking widespread discussion and questioning.

Apple responded by emphasizing EVS's privacy protections, claiming they are comparable to VLU's. Apple asserts that EVS utilizes techniques like homomorphic encryption, differential privacy, and OHTTP relays that hide IP addresses to prevent direct access to user photo information. However, Johnson and some media outlets argue that Apple's explanation doesn't fully alleviate concerns. While Apple claims to employ various privacy-preserving technologies, the default setting and the specific data transmitted lack sufficient transparency.

Furthermore, some reports indicate that even with Apple's claimed privacy protections, EVS has made errors in identifying landmarks in certain photos, suggesting location data isn't fully protected. This further intensifies privacy concerns surrounding EVS.

Technology news outlet 9to5Mac commented on the situation, stating that while iOS 18's EVS enhances user experience, it also raises privacy concerns. Although Apple highlights employed safeguards, the default setting and the specific data transmitted require more transparency to alleviate user anxieties. 9to5Mac's perspective reflects the widespread worry about the reliability of Apple's privacy measures and the transparency of its data collection and usage practices.

Johnson's critique and media commentary highlight a critical issue concerning Apple's approach to data privacy: the default enabling of potentially privacy-invasive features coupled with a lack of transparency regarding data handling. Even with claimed advanced encryption and privacy protections, the default enabling itself is problematic. Users should have complete control and explicitly choose whether to enable such features, rather than passively accepting them by default.

This incident underscores the need for tech companies to prioritize user privacy and data security when designing and deploying new features. Default enabling of potentially privacy-risking features, even with privacy-preserving technologies, can spark public distrust and discontent. Transparency and user control are key to maintaining user trust; tech companies must emphasize these aspects to ensure user data security and provide users with complete understanding and control over how their data is handled.

Apple needs to more clearly explain EVS's functionality, what data is collected, how it's used, and how it's protected. Simply stating that privacy-preserving techniques are used is insufficient. Users need specific details on how Apple balances user experience and data privacy. Only then can user concerns be truly addressed and trust rebuilt.

In conclusion, the default enabling of Enhanced Visual Search in Apple's iOS 18 and macOS 15 Sequoia systems has raised serious privacy concerns. While Apple claims to have implemented privacy protections, the default setting and lack of transparency remain unsettling to users. This incident serves as a reminder that tech companies have a responsibility to handle user data transparently and responsibly, empowering users with complete control over their personal information. Future similar features should allow for explicit user choice, rather than default enabling, to balance technological advancement with user privacy and foster a healthier digital ecosystem.
