Apple recently adjusted its encryption policy, attracting widespread attention. The new regulations may allow some iCloud data to use third-party encryption services, which, while enhancing cross-platform compatibility, breaks the traditional security architecture of its closed ecosystem. This move may be in response to pressure from the EU's Digital Markets Act and reflects the dilemma of seeking balance amid intensified competition in cloud services. Notably, the core device encryption mechanism remains intact, with biometric keys such as fingerprint and facial recognition still processed independently by the Secure Enclave. In the ongoing struggle between regulatory compliance and user privacy, Apple is attempting to carve out a new path between data fluidity and security boundaries, which may lead to a reconstruction of industry encryption standards in the future.
