Apple has suspended its most advanced safety encryption function for cloud data in Great Britain, a move that comes as a response to the British government’s demands for access to user data. The company announced this development on Friday, marking an unprecedented reaction to the government’s claims.

The affected function is called Advanced Data Protection (ADP), which enables end-to-end encryption for a wide range of cloud data. Apple stated that this function is no longer available for new users in Britain and that existing users may have to deactivate this safety feature.

This decision means that iCloud backups in Britain will no longer have end-to-end encryption, which would otherwise protect data such as iMessages from being accessed by Apple or handed over to authorities, even if required by law. If the end-to-end encryption is activated, not even Apple can access the data.

Governments and tech giants have long been at odds over strong encryption, with authorities viewing it as an obstacle to mass surveillance and crime control programs. However, the British government’s requirement is particularly far-reaching.

Early plans to offer Apple users the opportunity to fully encrypt the backups of their devices in the company’s iCloud service were dropped around 2018 after the FBI had privately complained, as previously reported by Reuters. However, the company finally implemented the plan in 2022.

The FBI has long expressed concerns about the erosion of access to digital evidence and threat information, referring to it as “going dark.” The bureau states on its website, “The rightful access to digital evidence and threat information erodes rapidly,” and refers to the “go dark” encryption.

Apple has consistently maintained that it would never incorporate a so-called backdoor into its encrypted services or devices, as such a feature could be exploited not only by governments but also by hackers. This stance is shared by security experts.

“Ultimately, it is only a matter of time before such a backdoor is found and malicious actors exploit it for cybersecurity at the Loughborough University in Great Britain.”

Data that was encrypted before the introduction of Apple’s protection service at the end of 2022, such as passwords and the messaging services iMessage and FaceTime, will remain encrypted.

Apple expressed disappointment, stating, “We are deeply disappointed that the protection that ADP offers will not be available to our customers in Britain, since the number of data protection violations and other threats for customers’ privacy is constantly increasing.”

The decision does not affect the encryption of data stored directly on devices. However, in the age of large photo collections, extensive messaging histories, and regular phone upgrades, many users find it impractical to store all their data solely on their devices. Exclusive storage on the device also means that if the device is lost or damaged, all user data could be lost, which, if not most consumers, British authorities can now access more easily.

Security concerns have led criminal prosecution authorities to target Apple services such as iMessage, via iCloud backups that were not end-to-end encrypted before Apple’s Advanced Data Protection was offered. These backups, which can contain photos and other sensitive information, can no longer be encrypted for British users, according to Apple.

Apple cannot deactivate ADP for existing users because it does not have an encryption key, but it will ask users to deactivate the function themselves. A spokesman for the British Ministry of the Interior refused to comment on whether such an order was granted. “We do not comment on operational matters, including confirmation or denying the existence of such communications,” said the spokesman.

The Washington Post reported this month that Britain issued a Technical Capability Notice to Apple that requires access to the data in the context of the extensive Investigatory Powers Act from 2016, which allows law enforcement authorities to force companies to collect evidence to help.

According to the government’s website, Technical Capability Notices (TCNs) do not grant blanket access to the personal data of users. Even if there is a TCN, separate permits are still required to enable access to data.

The Apple share was largely unchanged on Friday morning. The company has long resisted the government’s efforts to weaken encryption, as in 2016, when the U.S. authorities tried to force the company to unlock the iPhone of the San Bernardino shooter.

The efforts to undermine encryption go back to the 1990s when the government of former President Bill Clinton first suggested that computer hardware be used to incorporate a physical chip that would enable police officers and spies to extract encrypted communication. The attempt failed, and since then, strong encryption has found its way into a growing number of consumer services, including Apple’s iMessage, Zoom Meetings, WhatsApp from Meta, and the Signal app geared towards data protection.

Signal has already threatened to leave Britain due to similar concerns, while Meta has faced resistance due to its plans to expand encryption on WhatsApp.

This move by Apple highlights the ongoing tension between national security interests and privacy rights. As governments worldwide seek to balance these competing priorities, tech companies like Apple are increasingly finding themselves in the crosshairs. The implications for U.S. consumers are significant, as similar pressures could emerge in the U.S., where encryption and data privacy are hot-button issues.

In the U.S., the debate over encryption has been particularly contentious. In 2016, the FBI sought to force Apple to unlock an iPhone belonging to one of the San Bernardino shooters. Apple resisted, arguing that creating a backdoor for the government would compromise the security of all iPhone users. The case ultimately ended without a resolution, but it set a precedent for future battles over encryption.

As the digital landscape continues to evolve, the need for robust encryption will only grow. Companies like Apple are at the forefront of this battle, advocating for strong encryption to protect user data from both malicious actors and government overreach. The outcome of these battles will shape the future of digital privacy and security for consumers worldwide.

For U.S. consumers, the implications of Apple’s decision in Britain are clear: encryption is a critical tool for protecting personal data, and any weakening of encryption standards could have far-reaching consequences. It is essential for consumers to stay informed about these developments and advocate for strong encryption to safeguard their digital privacy.
