current fingerprint identification technology is still inadequate, Security is still not comparable to the traditional approach.We can use the following code to check if the current device is in security:
Keyguardmanager Keyguardmanager = (keyguardmanager) getsystemservice (context.keyguard_service);
if (Keyguardmanager.iskeyguardsecure ()) {

Recently, the project needs to use the fingerprint identification function, after consulting the relevant information, organized into this article.
Fingerprint recognition is a new feature after Android 6.0, so it is necessary to determine whether the system version of the user's phone supports fingerprint recognition
At the launch of the IPhone 5s, Apple unveiled a new fingerprint identification security technology, the Touch ID, that pioneered the next chapter in the use of biometric security technology on portable devices. Since then, Apple has brought this technology to the IPAD. No previous manufacturers have successfully built finger
Fingerprint recognition is a new feature after Android 6.0, so it is necessary to determine whether the system version of the user's phone supports fingerprint recognition when it is used. In addition, in the actual development scenario, there are two main scenarios for using fingerprints:

IPhone5S new fingerprint scan recognition sensor Touch ID, hackers spend a lot of time to show that fingerprint verification can be cracked. Even if it could be hacked, it still has great benefits for iphone5s security.Why is an easily cracked biometric verification method a great benefit to the security of iphone5s? Aside from the advantages and weaknesses of th

The example in this article describes the implementation of Android acquiring the MD5 value of APK signature fingerprint to prevent repackaging. Share to everyone for your reference, specific as follows:
Make a record (here is only the Java layer signature Check, Java layer is easy to be cracked, I suggest apk reinforcement)
Obtaining the MD5 value for APK signature verification prevents APK from being pa

In Android development, the SHA1 certificate fingerprint is often acquired. For example: When you embed a gold map, you need to use this stuff. This is directly available in eclipse, but is not provided directly in the Android studio and needs to be manually acquired by other means.
We can use a Java tool: Keytool to get this value. Keytool is a tool
