IOS keyChain (simple use of key string), ioskeychain In development, we usually need to save some values for a long time, such as the user's account and password. It is especially important to ensure data security for data with high privacy. KeyChain in ios is a good choice. First, go to the developer website (https://developer.apple.com/library/ios/navigation/) to download a sample project called GenericKe

The Apple developer program has been applied, and the next step is to export the certificate, but in accordance with the previously turned post operation, Http://www.cnblogs.com/cg-Yun/articles/4158177.html found that the private key cannot be exported.My system is currently the latest 10.10.1, Xcode is the latest 6.1.1.Workaround, in the Keychain tool, put the certificate in the system into the login and you can export the private key.Keychain Unable

Today in the integration of the Aurora Push SDK, the app ID and development according to this article, after the creation of the release certificate, found that the development and release certificate added to the system keychain after the export cannot select the P12 file, so there is no way to upload the laser push configuration to go, so the app ID, the certificate deleted the reconstruction , or not, but in the period of time you can export the P1

In Android 6.0, Google finally added fingerprint recognition to the Android system, a feature that has already been implemented on the iphone and has been implemented in-house in a number of custom ROMs by many vendors, a bit late for this feature. In Google's new release of Nexus Devices: Nexus 5x and Nexus 6p are carrying a fingerprint identification chip on the back of the device, as shown in the followi

Biometric identification technology is the use of human body inherent physiological characteristics (such as fingerprints, face, red film, etc.) and behavioral characteristics (such as handwriting, sound, gait, etc.) to conduct personal identification.Biometrics is more secure, more confidential and more convenient than traditional identification methods. Biometric identification technology has the advantages of easy forgetting, good anti-counterfeiting performance, easy forgery or theft, carryi

RefersThe ripple is the uneven texture on the front of the finger. Although fingerprint is only a small part of human skin, it contains a lot of information. Fingerprint features can be divided into two types: general features and local features. General FeaturesIt refers to the features that can be directly observed by the human eye, including the basic pattern, pattern area, core point, triangle point, st

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 fingerprint identification on such commonly used devices, because of the complex process

The rapid development of modern society, many occasions need identification, traditional identification technology can not meet the social requirements. Human body features are non-replicable, so people began to study biometric technology, and fingerprint is unique, life-invariant, difficult to forge and other characteristics, high security, and thus has been widely used. In some confidential departments, such as banks, hotels, computer rooms and so o

1 IntroductionFingerprint refers to the uneven surface of the skin on the tip of the finger. Although fingerprints are only a small part of the body's skin, it contains a lot of information. These skin lines in the pattern, breakpoints and intersections are different, in the information processing they are called "characteristics", depending on the uniqueness of the characteristics, you can be the user with his fingerprints, by comparing the fingerprint
