Some time ago, I heard my classmates say that their company's door cards are identified by fingerprints. If I wanted to work late, I could give the cards to someone else and help me with it. Now I want to do this, the difficulty is to increase a lot. after hearing about the fingerprint identification system, I don't know when to have a conjecture about this technology, that is, what kind of influence the development trend will have on the whole societ
The notebook is Dell XPS M1530. After Ubuntu 11.04 is installed, the basic devices are working normally and fingerprint recognition has never been taken care. Today, when I was idle, I felt like I had to drum up my fingerprint to see if it could be driven.
I searched for the following articles and found that their settings are not the same as those on my machine.
Finally, I finally succeeded and published
Java fingerprint recognition + Google Image Recognition Technology
Some time ago, when I saw this similar image search principle blog on Ruan Yifeng's blog, there was an impulse to implement these principles.
I wrote a demo of image recognition.

Material:
1, use the Magic Wand tool to select the fingerprint, magic wand tool tolerances I set to 32.
2, press ctrl+j copy a layer, in order to let everyone see clear effect, I put "Layer 1" hidden,
The effect chart is as follows
Implementation process
1. First introduce fingerprint to unlock the necessary header file
#import
2. Understand the main two methodsThis method is to determine whether the device supports TouchID.
-(BOOL) Canevaluatepolicy: (lapolicy) Policy error: (NSERROR * __autoreleasing *) Error __attribute__ ((Swift_error (none) ));
This is used to verify the TouchID, there will be pop-up box out.
We open the "settings" > "fingerprint" > "Fingerprint Management" on the phone and click on it to open the entry details as shown below.
All right, after we open the entry, we click on "Digital password" or "Mixed password" and then find the following "digital password", then set the password to: 1234, click "Continue", and then click "Input". Click "Input", you can prepare to enter the

Samsung phones also have their own platform and account number, we can register and then use the username and password login, if you are Samsung powder must have a Samsung account, if we have to bind the phone, in order to facilitate we can use fingerprint verification Samsung account login, so in the mobile phone login Samsung account does not need to enter the password, can be entered directly.
