我在SAMSUNG GALAXY 2手机上存储了一个重要文件(所以我可以在GO上编辑)。未经我的权限,我不希望别人访问此文件或文件。
我知道我可以锁手机,但这个选项意味着除非被解锁,否则无法在手机上完成。
我希望别人仍可从手机拨打电话,但不能访问存储卡。 (让别人使用我的手机是一个内部安排,即在我们一起旅行时有一个接触点)
有没有办法锁定存储卡(用密码),但留下电话解锁?

I have stored an important document on the SDHC card on my Samsung Galaxy 2 phone (so that I can edit it on the go). I don't want others to access this file or document without my permission.
I know I can lock the phone but this option means that nothing could be done on the phone unless it is unlocked.
I want others to still make calls from my phone but not be able to access the memory card. (Letting others use my phone is an internal arrangement i.e. so that there is one point of contact when we are travelling together)
Is there a way to lock the memory card (with a password) but leave the phone unlocked?
简单地,使用 boxcryptor ..它会加密您的文件&带AES-256标准的文件夹(AES-256由美国政府分类为保护"最重要的" 信息)。最好的事情:您可以在任何平台上使用它:Android,iOS,Windows,Mac,Linux。因此,您也可以使用Dropbox同步加密文件。
它的免费Android应用程序: https://market.android.com/details?id= com.coxcryptor.android (免费版本有只读访问的限制)。您甚至不需要一个根源的设备,而不是完全释放的情况 luks manager < / a>。如果您的设备rooted&amp;您还需要在不花钱的情况下编写访问权限,Go for luks manager ,但您将错过跨平台访问权限。因此,我的推荐是收到的 boxcryptor 如果您需要写访问。
加密,您的文件&amp;即使您的朋友是黑客,文件夹也会是安全的。凭借甚至最快的超级计算机,突破AES-256标准需求数十年甚至数百/千年(基于密码强度&amp;加密密码)。
Simply, use BoxCryptor.. It'll encrypt your files & folders with AES-256 standard (AES-256 is classified by the U.S. Government to protect xe2x80x9cTOP SECRETxe2x80x9d information). The best thing: You can use it on any platform: Android, iOS, Windows, Mac, Linux. So, you can sync your encrypted files with Dropbox, too.
Its free Android app: https://market.android.com/details?id=com.boxcryptor.android (Free version has limitation of Read-only access). You don't even need a rooted device whats not the case of fully free LUKS Manager. If your device is rooted & you also need write access without spending money, go for LUKS Manager, but you'll miss cross-platform access. So, my recommendation is paid BoxCryptor if you need write access.
With encryption, your files & folders will be safe even if your friends are hacker. With even fastest super computers, breaking AES-256 standard needs decades or even hundreds/thousands years (based on password strength & encryption passphrase).
加密最可能是您案例最合适的解决方案。沿着 luksmanager 可能是合适的工具。虽然您需要在任何情况下都需要扎根的手机,也许也许是一个修改的内核。
Encryption is most probably the most appropriate solution for your case. Something along the lines of LUKSManager could be the right tool. Though you would need a rooted phone in any case and perhaps a modified kernel, too.
您无法锁定,在您的定义中,sdcard或一个文件中。但是您有一些方法可以保护您的文件。
唯一的安全方法是加密它。如果您将SDCard与软件锁定,小偷可以轻松将其连接到PC并窃取文件甚至窃取整个SDCard。
You cant lock, in your definition, the sdcard or one file. But you have some ways to protect your file.
The only safe way is, to encrypt it. If you lock your sdcard with a software, the thief can easily connect it to a pc and steal the file or even steal the whole sdcard.
您是否考虑过手机中的SD卡并将其保留在安全位置,直到您需要访问重要文件?
afaik在SD卡上没有办法加密/保护单个文件。这使您正在寻找完全加密的卡,并且不支持框中的卡。而不是那个麻烦,为什么不简单地删除它?您不需要SD卡来使用基本电话功能(呼叫,短信),并且许多应用程序都可以在没有SD存储或移动到内部存储器。您的设备要求您关闭电源并拉动电池以访问Micro SD卡插槽;虽然,插入或移除卡,然后将手机推送,不应该花费比一分钟更长。
我说,保持简单。Have you considered just removing the SD card from the phone and keeping it in a safe spot until you need to access your important files?
AFAIK there isn't a way to encrypt/protect a single file on an SD card. That leaves you looking at fully encrypting the card which Android doesn't support out of the box. Instead of that hassle, why not simply remove it? You don't need an SD card to use basic phone functions (calls, SMS) and many apps can either do without SD storage or be moved to internal storage. Your device requires you to power down and pull the battery to access the micro SD card slot; insertion or removal of the card and then powering the phone back on, though, shouldn't take you much longer than a minute.
Keep it simple, I say.
如果您的手机植被(可能不是),您可能可以卸载卡,从我不知道系统是否尝试在某个时段后尝试在其自行传动。
If your phone is rooted(which it may not), you might be able to unmount the card, altough I dont know if the system tries to remout it on itself after some period.
