问题 I am new to Android Development. Now I want to integrate Fingerprint lock in my application. Which is the best. Please help me to find good fingerprint lock. 回答1: USING CAMERA AS FINGER LOCK as refernece check this Fingerprint Scanner using Camera As someone who's done significant research on this exact problem, I can tell you it's difficult to get a suitable image for templating (feature extraction) using a stock camera found on any current Android device. The main debilitating issue is

问题 Before implementing, I like to have an idea.Here is how i think it works, The first time user logs in into my app with username and password I save both the user and pass in my app. Second time, user willing to enter the app I give him option to use fingerprint inster of entering usename + password. If he uses fingerprint, I validate it and if validation is successful I use the saved username and password to call the login api. Is this way of thinking, and flow right? 回答1: To login with

问题 I have an Android application that has one feature which includes showing some content on a view when you unlock your screen after having locked it earlier, and like such it shows up 'in front' of the built-in lock screen (it only overrides it if you don't have any screen security and only swipe away from it). At the moment you need to swipe on your screen to get rid of the view of my app from the screen and to go to the lock screen to enter your security code or whatever security you might

问题 I just want to know what is your opinion about how to fingerprint/verify html/links structure. The problem I want to solve is: fingerprint for example 10 different sites, html pages. And after some time I want to have possibility to verify them, so is, if site has been changed, links changed, verification fails, othervise verification success. My base Idea is to analyze link structure by splitting it in some way, doing some kind of tree, and from that tree generate some kind of code. But I'm

问题 I am currently doing research on Android fingerprint API. As I have cloned the fingerprint sample, 'FingerprintDialog' https://github.com/googlesamples/android-FingerprintDialog There is a mechanism for checking if new fingerprint is added to the device and ask for password instead of fingerprint once after the addition of new fingerprint. However, I cannot find any material online about detecting the removal of fingerprint in the App. As the result, I would like to know if there is any

问题 i am working with digital persona u are u 4500 and oracle database, i got the problem to store fingerprint template to database, here part of my code string sqlInsert = "insert into mytable(ID,FINGERPRINT)"; sqlInsert += "values (:i_ID,:i_FINGERPRINT)"; OracleParameter iID = new OracleParameter(); iID.OracleDbType = OracleDbType.Varchar2; iID.Value = textBox1.Text; iID.ParameterName = "i_ID"; OracleParameter iFINGERPRINT = new OracleParameter(); iFINGERPRINT.OracleDbType = OracleDbType.Blob;

问题 Is there a way to detect the Operating System version of a web server using its IP address (with knowledge that the web server is running php). I haven't attempted to code it yet, as i am a beginner. Is it easy? Is it possible or not possible at all? 回答1: There's no official way to detect OS on a remote server across all operating systems and configurations. It's often considered a security risk to expose such information, since it can be used to research directed attacks based on the version

问题 Has anyone seen a way to do pinning with Alamofire with the fingerprint instead of the public key? Sorry if this has been answered, I haven't seen it anywhere. Thanks 回答1: This ended up being pretty straight forward. The code below might not be perfect, my real code is doing some addtional checks, but this is most of it. The .SHA1Fingerprint is an extension method on SecCertificate that copies it into NSData and then converts it to a SHA1. I use RNCryptor to do that, but you can do it however

问题 I want to compare two audio file for example mp3 and wav. I use musicg to compare by fingerprints. Wave record1 = new Wave(music1.toString()); Wave record2 = new Wave(music2.toString()); FingerprintSimilarity Similarity=record1.getFingerprintSimilarity(record2); System.out.println(Similarity.getSimilarity()); musicg work only on wav so I convert mp3 to wav using JAVE File temp = new File("temp.wav"); AudioAttributes audio = new AudioAttributes(); audio.setCodec("pcm_s16le"); audio.setBitRate
