-**''Partial removal of user information''** \\
-Choose unmasking for the information to be removed at all sections (infoMask, Partial Update families of functions, and user mask agreements). \\ \\
-**''Partial edit of user information''** \\
-Choose masking for the information to be edited at all sections (infoMask, Partial Update families of functions, and user mask agreements). \\ \\ \\ \\
-**''Default setting of user information''** \\
-Choose masking for infoMask and unmasking for Partial Update familes of functions and user mask agreements. \\ \\
-**''Changing credential information (Card/Fingerprint/Face)''** \\
-It checks if the credential information is allocated or not such as [numCards, numFingers, or numFaces is 0], [fingerObjs, cardObjs, faceObjs, or faceExObjs is NULL]. Plus, it checks infoMask. \\
-If the input information at card/fingerprint/face is greater than 0 and the mask at infoMask is set, the device credential information can be changed. \\
-For example, when the device has two fingerprints for a user, select masking at infoMask’s BS2_USER_INFO_MASK_FINGER, numFingers =1, and assign a fingerprint at fingerObjs. Then the device will have only one newly assigned fingerprint. \\
-To add a new fingerprint, three fingerprints must be assigned which includes the two previously stored fingerprints and the new fingerprint. \\ \\
-**''Keeping the credential information (Card/Fingerprint/Face)''** \\
-The device keeps the original credential information if the credential information at card/fingerprint/face is set to 0 and the infoMask is set to masking. \\ \\
-**''Removing the credential information (Card/Fingerprint/Face)''** \\
-If the credential information at card/fingerprint/face is set to 0 and the infoMask is set to unmasking, the device erases the corresponding information assigned to each credential. \\ \\
