透過手機螢幕上的餘熱猜測 PIN 碼

利用手機螢幕上的餘熱分析可能的 PIN 碼:「Heat traces left by fingers can reveal your smartphone PIN」,在輸入完 PIN 碼的 30 秒內的準確度都還是很高 (80%):

The report further revealed that if the thermal image is collected within 15 seconds of a PIN being entered, the technique is accurate almost 90% of the time. At 30 seconds, this accuracy decreased slightly to 80%. At 45 seconds or more, the accuracy dropped to 35% and below.

利用極高頻的音波跨裝置侵犯使用者隱私

在這篇看到現在已經有跨裝置的追蹤機制:「Beware of ads that use inaudible sound to link your phone, TV, tablet, and PC」。

電視廣告利用超高頻 (人類聽不到) 與手機或平板裝置上的應用程式配對,進而組合使用者的行為:

The ultrasonic pitches are embedded into TV commercials or are played when a user encounters an ad displayed in a computer browser. While the sound can't be heard by the human ear, nearby tablets and smartphones can detect it. When they do, browser cookies can now pair a single user to multiple devices and keep track of what TV commercials the person sees, how long the person watches the ads, and whether the person acts on the ads by doing a Web search or buying a product.

難以被關閉的追蹤機制,看起來就是 NSAFBICIA 之類超愛的技術。

Nokia 以 166 億美金買下 Alcatel-Lucent

在「Nokia to acquire Alcatel-Lucent」這邊看到的報導,Nokia 以 166 億美金買下 Alcatel-Lucent

Nokia 的新聞稿在「NOKIA AND ALCATEL-LUCENT TO COMBINE TO CREATE AN INNOVATION LEADER IN NEXT GENERATION TECHNOLOGY AND SERVICES FOR AN IP CONNECTED WORLD」這邊。

其中 OSNews 被拿出來講的... 由於 Nokia 將手機部門賣給了微軟,所以 Nokia 其實是不能發展手機的 (應該有時間限制),但是 Alcatel-Lucent 現在手上有:

Nokia is not allowed to make smartphones for a while, but Alcatel-Lucent does make smartphones.

而這是從 HP 買來的 Palm... (所以 Nokia 又要玩什麼花招了 @_@)

用 Raspberry Pi 自幹一台 3G 手機...

在「DIY Smartphone」這邊看到用 Raspberry Pi 做出一台手機:

DIY Smartphone using Raspberry Pi A+ Pi, Camera, PiTFT, and Adafruit FONA with custom mobile OS.

然後 FAQ 的部份 XDDD

The thing is a inch thick! Why would you build something so useless when you can buy a cheap phone for less that can do much much more?

No reason.

可以看到超大隻超陽春:

加州的手機防竊提案...

由於手機的行竊與搶劫案件已經是美國目前遇到的重大問題,所以有幾位法界人士提案,要立法強制對手機業者實作行動電話的防竊機制:「Proposed California Law Would Mandate Smartphone Kill Switch」,報導在「Proposed California law would mandate smartphone kill switch」。

希望藉由這套防竊機制,讓銷贓變得困難,希望藉此降低手機行竊與搶劫的案件數量...

Kill Switch 的機制並沒有詳細說明,不過應該就是類似目前 Apple 的方式?可以遠端強制對手機下鎖上甚至銷毀的命令...
