How to check device compatibility for finger print authentication in android

You have to use method isHardwareDetected on FingerprintManager class. Determine if fingerprint hardware is present and functional. Returns true if hardware is present and functional, false otherwise. // Check if we’re running on Android 6.0 (M) or higher if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { //Fingerprint API only available on from Android 6.0 (M) FingerprintManager fingerprintManager = … Read more

Android fingerprint API for time attendance app [closed]

No. In fact, the Android Compatibility Definition for Android 6.0 states in the Fingerprint section (7.3.10): MUST NOT enable 3rd-party applications to distinguish between individual fingerprints. Therefore while you could write an app that uses fingerprint as a mechanism to authenticate the user, any registered fingerprint associated with the current user account could be used. … Read more

Error “The authenticity of host ‘github.com’ can’t be established. RSA key fingerprint “

You should simply be able to answer ‘yes‘, which will update your ~/.ssh/known_hosts file. A better approach, to avoid any MITM (Man-In-The-Middle) attack, would be (as commented below by Mamsds) to verify GitHub’s public key first (see “GitHub’s SSH key fingerprints“) and, if you find a match, then you can answer ‘yes’. Example: ssh-keyscan -t … Read more

Image fingerprint to compare similarity of many images

Normal hashing or CRC calculation algorithms do not work well with image data. The dimensional nature of the information must be taken into account. If you need extremely robust fingerprinting, such that affine transformations (scaling, rotation, translation, flipping) are accounted for, you can use a Radon transformation on the image source to produce a normative … Read more
