11 Tips iOS 11 yang wajib kamu tahu

Apple sudah resmi merilis iOS 11. Sistem operasi terbaru dari Apple ini memiliki dua hal penting. Pertama personalisasi perangkat lewat teknologi machine learning yang tersinkronisasi antar perangkat serta peningkatan multitasking di iPad dengan dock, fitur drag and drop serta aplikasi manajemen dokumen Files. Update iOS 11 kali ini khusus untuk perangkat dengan prosesor 64 bit. Apabila kamu sudah update, berikut ini ada 11 tips yang wajib kamu tahu. Apa saja?

→ Apple Watch Series 3 dengan LTE hanya bisa digunakan di negara tempat beli

Dikutip dari MacRumors:

With the LTE-enabled Apple Watch Series 3 only available in a handful of countries at the current time, it might be tempting to purchase one in another country, but it won’t work. Series 3 models appear to be limited to connectivity in their original country of purchase.

An Apple support representative who spoke to MacRumors reader Thomas said that an Apple Watch purchased in the U.S. online store will only work with the four carriers in the United States, perhaps due to hardware limitations.

 

→ Masih tentang Face ID, oleh Craig Federighi

Selain iPhone X dengan desain bezel yang tipis, Face ID juga menjadi salah satu topik pembicaraan terhangat setelah Apple Event. Banyak pertanyaan mengenai teknis teknologi Face ID atau perhatian akan keamanan dari data wajah yang tersimpan. Melalui percakapan via telepon yang kemudian diwartakan Matthew Panzarino via Techcrunch, Craig Federighi memaparkan bagaimana Apple mengumpulkan dan memproses data FaceID tersebut:

“Phil mentioned that we’d gathered a billion images and that we’d done data gathering around the globe to make sure that we had broad geographic and ethnic data sets. Both for testing and validation for great recognition rates,” says Federighi. “That wasn’t just something you could go pull off the internet.”

Especially given that the data needed to include a high-fidelity depth map of facial data. So, says Federighi, Apple went out and got consent from subjects to provide scans that were “quite exhaustive.” Those scans were taken from many angles and contain a lot of detail that was then used to train the Face ID system.

Sama seperti Touch ID, Apple tidak pernah mengirimkan detail atau data pemindaian wajah ke server manapun. Semua pengolahan data terjadi di perangkat dan disimpan ke prosesor Secure Enclave.

“We do not gather customer data when you enroll in Face ID, it stays on your device, we do not send it to the cloud for training data,” he notes.

[…]

The simple answer, which is identical to the answer for Touch ID, by the way, is that Apple does not even have a way to give it to law enforcement. Apple never takes possession of the data, anonymized or otherwise. When you train the data it gets immediately stored in the Secure Enclave as a mathematical model that cannot be reverse-engineered back into a “model of a face.” Any re-training also happens there. It’s on your device, in your SE, period.

Salah satu detail mengenai Face ID yang saya rasa perlu diketahui oleh setiap pengguna iPhone X nantinya adalah Apple tidak pernah menyimpan gambar wajah pengguna untuk Face ID. Dalam percakapan tersebut, Craig juga menjelaskan beberapa detail tambahan mengenai Face ID, terutama beberapa kondisi dimana kamu tetap membutuhkan passcode untuk membuka iPhone X.

  • If you haven’t used Face ID in 48 hours, or if you’ve just rebooted, it will ask for a passcode.
  • If there are 5 failed attempts to Face ID, it will default back to passcode. (Federighi has confirmed that this is what happened in the demo onstage when he was asked for a passcode — it tried to read the people setting the phones up on the podium.)
  • Developers do not have access to raw sensor data from the Face ID array. Instead, they’re given a depth map they can use for applications like the Snap face filters shown onstage. This can also be used in ARKit applications.
  • You’ll also get a passcode request if you haven’t unlocked the phone using a passcode or at all in 6.5 days and if Face ID hasn’t unlocked it in 4 hours.

Laporan Matthew Panzarino di Techcrunch ini wajib kamu baca jika ingin mengetahui lebih detail mengenai Face ID.

→ Masih ingat demo Face ID yang gagal? Ternyata ini dia penyebabnya

Masih ingat ketika Face ID gagal mengautentikasi Craig Federighi sewaktu demo iPhone X? Ternyata penyebabnya bukan karena kegagalan sistem dari Face ID melainkan masalah teknis lain. Seperti yang dikutip dari Yahoo News, Face ID tidak bisa mengautentikasi Craig dikarenakan perangkat yang pertama kali digunakan tersebut telah mencoba mengenali pegawai Apple yang mempersiapkan demo dan gagal.

Mekanisme ini sama persis ketika kamu coba memindai sidik jari dengan Touch ID namun gagal lebih dari 5 kali lalu muncul tulisan “Your passcode is needed to enable Touch ID”.

David Pouge mewartakan via Yahoo:

“People were handling the device for stage demo ahead of time,” says a rep, “and didn’t realize Face ID was trying to authenticate their face. After failing a number of times, because they weren’t Craig, the iPhone did what it was designed to do, which was to require his passcode.” In other words, “Face ID worked as it was designed to.”
