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

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).
