# Apple’s Improved Visual Search in iOS 18.1: Progress or Privacy Issue?
Apple has a longstanding reputation for its dedication to innovation and user privacy, yet its newest feature in iOS 18.1, **Improved Visual Search**, has ignited a vigorous discussion. While this feature showcases remarkable capabilities, enabling users to search for images based on landmarks or points of interest, it has simultaneously triggered considerable apprehension regarding privacy and user consent.
## What Is Improved Visual Search?
Improved Visual Search is a cutting-edge addition to Apple’s Photos app that utilizes artificial intelligence (AI) to assist users in rediscovering moments captured in their photo libraries. By recognizing landmarks, points of interest, or other prominent attributes in images, the feature allows users to search their photo collections with enhanced accuracy. For example, entering “Eiffel Tower” into the search bar would display photos from your visit to Paris.
Apple asserts that the feature is created with privacy as a priority, employing advanced technologies such as **homomorphic encryption**, **differential privacy**, and an **Oblivious HTTP (OHTTP) relay** to safeguard user information. As stated in Apple’s [privacy policy](https://www.apple.com/legal/privacy/data/en/photos/), these protocols ensure that the company cannot access or gather insights about the content of your images.
Nonetheless, even with these claims, detractors contend that the feature raises ethical dilemmas regarding user consent and data management.

## How Does the Technology Operate?
Improved Visual Search employs a blend of local and cloud-based machine learning to examine photos. Here’s a breakdown of the procedure:
1. **Local Analysis**: A machine-learning model on your device reviews your photos to spot areas of interest, like landmarks or significant features.
2. **Vector Embedding**: When the AI identifies a potential match, it creates a vector embedding—a mathematical representation of the image’s key characteristics.
3. **Encryption**: The vector embedding undergoes encryption via homomorphic encryption, which allows computations on encrypted data without the need to decrypt it. This guarantees that neither Apple nor third parties can see the actual image.
4. **Global Index Comparison**: The encrypted information is matched against a global index of landmarks and points of interest stored on Apple’s servers. The OHTTP relay conceals your IP address during this phase, providing an additional layer of privacy.
Although this technology is undeniably advanced, the dispute centers around its implementation.

## The Privacy Discussion: Opt-Out vs. Opt-In
A major point of contention regarding Improved Visual Search is that it is activated by default, and users do not have the option to opt out prior to their photos being analyzed. This has raised alarms that Apple is favoring functionality over user consent.
### Key Issues:
1. **Lack of Transparency**: Apple did not broadly announce the feature upon its launch, leaving numerous users unaware of the photo analysis.
2. **Absence of Pre-Analysis Opt-Out**: Even though users can turn off the feature in the settings, the analysis happens automatically before they have the opportunity to opt out.
3. **Privacy Claims Questioned**: Despite Apple’s promises regarding encryption and privacy, critics argue that the unilateral nature of the feature compromises its commitment to user empowerment.
Jeff Johnson, a software developer, brought attention to these concerns in a [series of articles](https://lapcatsoftware.com/articles/2024/12/4.html), criticizing Apple for its lack of transparency and user autonomy. He contends that while the technology might be secure, its rollout contradicts Apple’s supposed privacy-first values.

## Apple’s Justification: Privacy by Design
Apple has addressed these issues by highlighting the privacy protections incorporated within Improved Visual Search. The company points to its application of homomorphic encryption and differential privacy as proof that user data remains protected. Additionally, the OHTTP relay ensures that Apple cannot connect photo searches to individual users.
In a [technical document](https://machinelearning.apple.com/research/homomorphic-encryption), Apple clarifies that the encryption methods implemented make it mathematically unfeasible for the company to access the content of users’ photos. This aligns with Apple’s broader dedication to privacy, a principle that has long been central to its marketing and product development strategies.
However, even with these protections, the absence of an opt-in option has left numerous users feeling uncomfortable.

## How to Turn Off Improved Visual Search
If you are concerned about privacy and would like to deactivate Improved Visual Search, follow these steps:
1. Open the **Settings** app on your iPhone or iPad.
2. Navigate to the **Apps** section and select **Photos**.
3. Turn off the **Improved Visual Search** option.
On Mac, you can disable the feature by launching the Photos app, going to **Settings**, and selecting the **General** tab.
It is essential to understand, however, that turning off the feature does not reverse the analysis that has
