August 3, 2006 11:17:00 published by: Wu, Google researcher Any piece of information text can correspond to a not too long random number, as a fingerprint (fingerprint) that distinguishes it from other information. As long as the algorithm is well designed, the fingerprints of any two pieces of information are hard to duplicate, just like human fingerprints. Information

In addition, there are t
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
fingerprint identification technology is the most convenient, reliable, non-invasive and inexpensive solution for the identification of many biometric technologies used in authentication . .Fingerprints are unique features of the human body, with the characteristics of being portable, unique, non-replicable, absolute confidentiality, and their complexity is sufficient to provide sufficient characteristics for identification; if we want to increase r
Algorithm (c) aiming at the problem of small area fingerprint, this paper proposes and practices a novel method, attempts to identify a wider range of images, and effectively reduces redundant storage and computation. For fingerprints, it is possible to approximate the use of the Level3 feature, different from the algorithm (one) to the number of characteristics of the limit, also different from the algorithm (ii) will lead to hundreds of KB of templa
Overview This article discusses how to query the TCP/IP protocol stack of a host to collect valuable information. FirstFirst, I enumerated several "classic" operating system identification methods outside the stack fingerprint. And thenI described the "process status" of the stack fingerprint tool. Next, let the remote host leak itsSome techniques of information. Finally detailing my implementation (NMAP),
The term fingerprint recognition sounds familiar, but it's not used much in the actual development process. Google started with Android6.0 (API23) to provide standard fingerprint recognition support, and to provide external fingerprint identification related interface. In addition to fit 6.0 and above system, the main also provides 6.0 of the following equipment
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
