How to Set Up Your iPhone to prevent the FBI from cracking

 

Recently, the press has been most concerned with the debate between Apple and American courts. The US Court asked Apple to cooperate with the FBI to unlock the mobile phone number of the murderer in last December and provide "appropriate technical assistance" to help investigators unlock the iPhone 5c. Apple publicly said it would challenge the decision of the court.

The debate on the boundaries between privacy and security is everywhere. As a common user, one small question I want to ask now is-very simple-what kind of iPhone cannot be cracked by the FBI? After reading the relevant reports, I found that it was like this:

I. It cannot be cracked by the FBI. If the "brute force" attack is used, the FBI can theoretically crack the attack.

2. The FBI does not use brute-force cracking. Because iOS has a "erase data" confidentiality function, it will be started after 10 wrong passwords are entered, clear mobile phone data-in that case, no evidence is available. That is to say, the use of "brute force" cracking may result in the elimination of evidence.

3. "erase data" is disabled by default in iOS, but the FBI does not even know whether the murderer has enabled this function because the system cannot be accessed! The FBI applied to the court and asked Apple to cooperate to disable the "erase data" function.

It turned out to be the iOS function, which made the FBI not dare to act rashly. As a common user, the question I want to ask now is -- simpler -- how can I enable the "erase data" function that is disabled by default by TM?

It turns out to be in "Settings"> "general"> "password lock" of iOS. After opening it, I suddenly felt that Apple had become the last line of defense between citizenship and the FBI-as long as Apple turned this function off, everything was under the FBI.

When the "brute-force cracking" mode is enabled, the FBI will constantly try the password combination until it matches the settings of the investigation target in iOS. As a common user, one small question I want to ask now is -- very simple -- what kind of password should I set in order to resist "brute force cracking "? Someone on Twitter answered this question: <喎?http: www.bkjia.com kf ware vc " target="_blank" class="keylink"> VcD4NCjxwPjxpbWcgYWx0PQ = "" attach = "" datatime = "1455849743912" src = "http://www.bkjia.com/uploads/allimg/160224/035Z541a-2.png" title = "\"/>

It takes 80 ms to guess the password. The four-digit password takes 13.3 minutes, the six-digit password takes 22.2 hours, and the six-digit password takes over 300 years. However, this table is not detailed enough. QZ makes a more detailed statistics:

Great! I just chose a password combination with lowercase letters and numbers! Bigbrother1984!
