Amazon removes encryption function from Fire OS 5 secretly using tablet and others



Apple has strengthened its security from iOS 8, and even if Apple does not know the passcode, even Apple is trying not to trace the user's terminal, and in response to the government's request that "I want you to make backdoor"It shows a strong rejection attitude. On the other hand, Amazon seems to be a policy to cancel encryption function after Fire OS 5 and later.

The encryption function release from Fire OS 5 and later was attracted by Mr. David Scovetta's post on Twitter on March 3rd. The screenshot of Scovetta's uploaded user guide shows that encryption support for the fourth generation Fire HD and Fire HDX 8.9 will soon disappear, and in addition, "Your device has been encrypted. In Fire OS 5. Follow the steps outlined below to save your data (Your device is encrypting data, but Fire OS 5 does not support device encryption in the future.) Protect the data in the following way Please) "It is written.

Overseas news siteArs TechnicaContacted Amazon and asked about the above, the person in charge said, "When we released Fire OS 5 in the fall, we deleted some of the features that users are not using," he said. Meanwhile, "It's also encrypted, so communication on Amazon's cloud at all Fire tablets is done and a very high level of security is maintained" was explained. In other words, although security is maintained with respect to the connection between the Fire tablet and the external server, Ars Technica can easily acquire the user's data with a malicious attacker or government.
