Notes
：
User ID and Permission in three commands.
6. Add users and upload eigenvalues
（
CMD =8Byte/ACK > 8 Byte
）
T his commands are similar to “5. add fingerprint”, you should add triple times as well.
a) First
Same as the First of ” 5. add fingerprint ”
b) Second
S ame as the Second of ” 5. add fingerprint ”
c) Third
