1. Account management

1.1 Register

If you are a new comer, you need to register an account firstly to assess the resources of BIT.

Please click the link of "Register" on the home page to register an account. You should provide genuine personal information otherwise your registration request may be rejected. It is strongly recommended to use the email address of your organization rather than a free email account for registration.

Your registration information will be examined by the service team of BIT. If you successfully pass the examination, you will receive a confirmation email. Please activate your account by clicking the link on the email.

1.2 Password problem

If you forget your password, please click the link of "Reset" on the home page to get a new password through email.

You can login BIT to modify the randomly generated password.

2. Download biometric databases

BIT mainly has two purposes. One is for biometric database sharing and the other is for algorithm evaluation. So the biometric databases on BIT are classified to two parts accordingly. One part is publicly available for download and the other part is sequestered for performance evaluation of biometric algorithms.

Registered users should login the BIT to download publicly available iris, face, fingerprint, palmprint, multi-spectral palm and handwriting databases.

Since the files of biometric databases are huge in size, it is recommended to use the download software which has the function to resume broken downloads.

Users are suggested to read the description document of each database before download. If you only need a small dataset, you can download a subset file of your interested database.

The download speed may be slow when many users are downloading the biometric databases simultaneously. So please be patient or try again later.

3. Algorithm evaluation

Users need to complete the following steps to perform algorithm evaluation:

Login BIT

Submit an algorithm

    Users can submit their face, fingerprint or iris recognition algorithms for third-party performance evaluation by BIT.

    The basic information for each biometric algorithm such as its name, version, type, modality, description must be provided during algorithm submission. In addition, users are required to report the self-tested results (ROC, EER, etc.) of their algorithms on publicly available databases of BIT. To reserve the limited computational resources of BIT to test high-performance biometric algorithms and track state-of-the-art of biometrics, only qualified biometric algorithms will be tested by the BIT system. The definition of qualified biometric algorithms is as follows.

For an iris recognition algorithm, its EER must be less than 3% on CASIA-IrisV4-Thousand.

For a fingerprint recognition algorithm, its EER must be less than 5% on CASIA Fingerprint Image Database Version 5.0.

For a face recognition algorithm, its EER must be less than 8% on CASIA Face Image Database Version 5.0.

For any biometric algorithm, the average processing time for feature encoding should be less than 2 seconds and the average processing time for feature matching should be less than 1 second.

     A biometric verification algorithm should include two executables in the form of Win32 console applications, i.e. enroll.exe and match.exe. Example of the application functioning, through command-line:
> enroll imagefile templatefile outputfile
> match templatefile1 templatefile2 outputfile

    To help users quickly master the programming protocols of algorithm evaluation, the source codes of the example files "enroll.c" and "match.c" are provided for download.

Create a test task

     Users need to create a new test task to start the testing process of BIT by clicking the "New" item on the "Tests" area of the left menu. Users need select an algorithm and a database to submit an application of algorithm evaluation. It takes about one month to finish a testing task because of millions of biometric comparisons in a test task. Once the test task has been finished or abnormally interrupted due to errors of submitted algorithm, the user will be informed by email.

     Users can browse and edit the submitted test tasks by clicking the "browse" item on the "Tests" area of the left menu.

Publish results

     Users can decide whether to publish the testing results or not. If you choose to publish the testing results, the testing report will be publicly available for download and the performance metrics of your algorithm will be compared with others. If your algorithm performs well, it may be included in the Top5 list.

Get the biometrics performance certification by IAPR TC4

     The testing report of high-performance biometric algorithms will be certified by the IAPR TC4.
