The IOS 8 SDK exposes Touch ID fingerprinting to developers, allowing the app to authenticate users locally.You can use your fingerprint to verify your identity in just 2 steps:1. Check if Touch ID is available.2. Obtain fingerprint verification results.1Lacontext *mycontext =[[Lacontext alloc] init];2 if([Mycontext canevaluatepolicy:lapolicydeviceownerauthenticationwithbiometrics Error:nil]) {3[Myconte

1. Under the Samsung Flat sm-t713 (6.0.1) standby page, click "Application".2. Then in the application interface we click the "Settings" option.3. After opening the Access interface, we find the "lock screen and security" option in the Settings list, and the effect is as follows.4. Okay, so when we open it, we'll find the "fingerprint" option.5. Then in the open settings we click the "Add fingerprint" optio

iOS Development Exchange Group: 484884085You are welcome to increase.For example, the following code is to implement the call of more than 5S device fingerprint identification code, according to the code given by the official website, will appear after the successful recognition after a very long time to run successfully after the call code, stroll for a very long time. Just know to put it into the main thread to achieve talent enough.Detailed code su

The RABIN-KARP algorithm has good practicability for random string matching problems. It is based on the fingerprint mentality.The main string length is n mode string length is MAssume※① we can calculate a P's fingerprint at O (m) time F (P)※② if F (P) is not equal to F (t[s). S+M-1]) then p must not be equal to t[s. S+M-1]※③ we can compare fingerprints at O (1) time※④ we can at O (1) time from F (t[s. S+M-

Samsung phones also have their own platform and account number, we can register and then use the username and password login, if you are Samsung powder must have a Samsung account, if we have to bind the phone, in order to facilitate we can use fingerprint verification Samsung account login, so in the mobile phone login Samsung account does not need to enter the password, can be entered directly. 1. In the Samsung A5100 mobile phone interface in stan

1. In the Samsung A8 (A8000) main screen, then slide the interface2. In the new interface to find "set" details as shown below3. In the Open interface find the following "lock screen and security" as shown in the set interface.4. Then we open the "fingerprint" option on the Open interface, details below.5. Place the registered fingerprint finger on the home key or enter an alternate password to authenticate

A while ago has been in the progress of the project, not too much time to write a blog, now finally free, the previous owed to the blog to fill up.After iOS8.0, the API opens up the functionality of fingerprint verification. Although the open API can only be used as a validation, it is more restrictive, but it is sufficient for apps with similar "gesture password" functionality. With this new API, you can unlock a large number of apps in the app.The m

Operating System (OS) identification is an important information to be collected for intrusion or security detection. It is the basis for analyzing vulnerabilities and various security risks. The security status of a remote host can be further evaluated only when the operating system type and version of the remote host are determined.Since the TCP/IP protocol stack is described only in the RFC documentation, there is no unified implementation standard, as a result, companies have made different

1. First, we need to input our fingerprints on our iphone/ipad, that is, touch ID.2. Click "Touch ID and password" in "settings" to enter the fingerprint. 3. After entering the information, return to the mobile desktop and click "Alipay" to enter the software. 4. Click "my" in the lower right corner to go to the "Settings" option. 5. Click the "tool ID" button in the upper right corner (as sh

Web application fingerprinting is a critical pre-invasion step, assuming that the name and version number of the Web application can be determined through fingerprint identification. The next step is to search the web for publicly available vulnerabilities. or online search its source code and then carry out a white box of vulnerability mining.The core principle of fingerprint recognition is to match the MD

From the beginning of the computer, we have been emphasizing the security of personal computers, has been the way we protect the computer is mainly the password, but the password has a lot of defects, and now there are many ways to crack, so in the powerful ghost Win7, There has been a better way to ensure the safety of the computer, that is, fingerprint identification function, we want to know how Win7 computer f
