6.14. Session and Global Parameter Constants (ABS_PARAM_xxxx)
These constants identify each parameter and can be used as value of parameter dwParamID of ABS-
SetSessionParameter and ABSGetSessionParameter (for session parameters) functions, or ABSSet-
GlobalParameter and ABSGetGlobalParameter (for global parameters).
ABS_PARAM_CONSOLIDATION_COUNT 1
Specifies count of finger swipes for consolidation.
Consolidation is a process used for merging information acquired from multiple fingerprint templates
to one high-quality template, used in enrollment process. This parameter determines how many
templates are consolidated into one enrollment template.
When set to zero, dynamic enrollment is used. In this mode, the enrollment operation continues until
the resulted enrollment template has some minimal threshold quality.
The Value is represented as ABS_DATA with 1 byte of length. This byte is interpreted as unsigned
count of finger swipes.
Default value is zero (i.e. the dynamic enrollment). Note that currently only values 0 (dynamic
enrollment) and 5 are supported.
ABS_PARAM_CONSOLIDATION_TYPE 2
Determines type of consolidation.
I.e. how multiple templates are mixed together, to get one high-quality template. See description of
parameter ABS_PARAM_CONSOLIDATION_COUNT as well.
Value is represented as ABS_DATA with 1 byte of length. The value can be any constant
ABS_CONSOLIDATION_xxxx. See description of those constants.
ABS_PARAM_MATCH_LEVEL 3
Determines required level of security for comparing two templates with ABSVerifyMatch.
Value is represented as ABS_DATA with 1 byte of length. For the list of supported values, see
ABS_MATCH_xxxx.
ABS_PARAM_DISABLE_SENSOR_SLEEP 4
Disables sensor sleeping.
Value is represented as ABS_DATA with 1 byte of length. When zero, BSAPI can switch the device to
sleep mode, to save power. When non-zero, the sleep mode is disabled.
ABS_PARAM_DISABLE_SELECTIVE_SUSPEND 5
Allows to disable the selective suspend.
Value is represented as ABS_DATA with 1 byte of length. When zero, the selective suspend can be
used. When non-zero, the selective suspend is disabled.
ABS_PARAM_POWER_SAVE_MODE 6
Sets
default
power
safe
mode,
if
it
is
not
disabled
completely
with
ABS_PARAM_DISABLE_SENSOR_SLEEP.
Value is represented as ABS_DATA with 1 byte of length. Possible values are: 0 – power save is
always off (high power consumption); 1 – power save is always on (minimal power consumption,
higher time latencies can occur); 2 – power save switching depending on the user activity.
