The processor 115 stores the user-specific biometric information (or biometric data generated based on the biometric information) in a corresponding storage area of the memory 130 (ie, a storage area allocated for each user among all storage areas). The same storage area (or capacity) can be allocated for each user.

Processor 115, until the accumulation rate of the biometric data accumulated to register biometric information for each user in the memory 130 (or the rate at which biometric information is accumulated in the memory allocated for each user) becomes 100%, The biometric information of the user to be registered transmitted from the information input module 180 may be received, biometric data may be generated from the received biometric information, and the generated biometric data may be accumulated in the memory 130.

Here, the cumulative rate is a percentage of how much biometric information is recognized based on when 100% of the biometric information per user (or ID) is recognized, and the amount of memory used when 100% biometric information is recognized Assuming that A is A and the amount of memory used when 70% of the biometric information is recognized is B, the accumulation rate (R=B/A) is 70%. For example, the accumulation rate of biometric information for each user (or for each ID) has a correlation with the amount of memory allocated for each user (or for each ID).

In addition, when the memory usage is allocated as 4Kbyte for each user (or for each ID), even if the biometric information is stored in the memory allocated for each user within a tolerance (e.g., 10%) of 3.6Kbyte or more, the processor 115 May determine that 100% of the biometric information is accumulated.

For example, when each biometric image corresponding to the biometric information for each user is generated, the processor 115 uniquely distinguishes from each of the biometric images for each user (e.g., the point at which the ridge ends and the ridge line Biometric information may be accumulated for each user by extracting the location, direction, and/or shape of the branch point of, and processing (eg, combining or synthesizing) feature points extracted from each of the biometric images.

Here, when the accumulation rate of the accumulated biometric data is 100%, the memory capacity (or usage, for example 4Kbyte) allocated to the user to be registered is defined as being filled, and when the accumulation rate of the accumulated biometric data is less than 100%, The amount of memory allocated to the user (or usage, for example, 4Kbyte) is defined as not being filled.

Therefore, the processor 115 can calculate the accumulation rate of biometric data and the amount of allocated memory in real time, so whether the accumulation rate of the biometric data is 100% or whether the amount of memory allocated to the user to be registered is all filled. I can judge.

2 is a flowchart illustrating an operation of a digital door lock capable of outputting an accumulation rate of biometric information according to embodiments of the present invention.

A process of registering biometric information (or biometric data generated based on the biometric information) in the memory 130 will be described in detail with reference to FIGS. 1 and 2. For convenience of explanation, it is assumed that biometric information is fingerprint information, but the technical idea of the present invention is to store iris information, palmistry information, facial recognition information, or vein recognition information (or data generated based on such information) into the memory 130. This also applies to the process of registering with.

When a user recognizes his/her finger to the biometric information recognition module 180 to register his/her biometric information (eg, fingerprint) in the digital door lock 100A, the biometric information recognition module 180 Alternatively, fingerprint information) is recognized and the recognized biometric information (eg, fingerprint information) is transmitted to the processor 115, and the processor 115 receives the biometric information (S105).

The processor 115 receives the biometric information transmitted from the biometric information input module 180, generates biometric data by image processing the received biometric information, and accumulates the generated biometric data (eg, feature points) (S110). ).

The processor 115 displays the change in the accumulation rate of the accumulated biometric data in real time using keys (eg, key LEDs or separate LEDs different from the key LEDs) included in the keypad 120 (S115). ). Displaying the cumulative rate or the change in the cumulative rate using the keys in real time refers to LEDs (eg, key LEDs or LEDs (or LEDs) implemented separately from the key LEDs) indicating the operation of the keys. This means that the accumulation rate or the change in the accumulation rate is displayed in real time.

According to embodiments, when the accumulation rate of the accumulated biometric data is displayed in units of 10, the accumulation rate of the accumulated biometric data is indicated by one key (or an LED related to the key) among keys included in the keypad 120. It can be (S115).

For example, when the accumulation rate of the accumulated biometric data is less than 0% to 10%, the processor 115 may display the accumulation rate using the numeric key '1' included in the keypad 120, and the accumulated biometric data When the accumulation rate of is 10% or more and less than 20%, the processor 115 may display the accumulation rate using the numeric key '2' included in the keypad 120, and the accumulation rate of the accumulated biometric data is 90 When the percentage is greater than or equal to 99%, the processor 115 may display the accumulation rate using the numeric key '9' included in the keypad 120, and when the accumulation rate of the accumulated biometric data is 100%, the processor ( 115) may display the accumulation rate using a numeric key '0' or a special key (eg, # or *) included in the keypad 120.

Accumulation rate of the accumulated biometric data (or the amount of memory allocated to the user) by using one of the keys included in the keypad 120 (LED related to the key or an LED arranged separately from the LED related to the key) The ways of displaying) can be variously modified. As described above, the accumulation rate may be displayed as an LED (or a plurality of LEDs) related to a key capable of displaying the accumulation rate is lit or flashed.

According to embodiments, when the accumulation rate of the accumulated biometric data (or the amount of memory allocated to the user) is displayed as a quantity (eg, a percentage), the accumulation rate of the accumulated biometric data is included in the keypad 120. Among the keys may be indicated by at least two keys (or at least two LEDs associated with at least two keys).

For example, when the accumulation rate of the accumulated biometric data is 35%, the processor 115 may sequentially display '3' and '5' using numeric keys '3' and '5', and the accumulated biometric data When the cumulative rate of is 100%, the processor 115 may sequentially display '1', '0', and '0' using number keys '1' and '0'.

As another example, when the accumulation rate of the accumulated biometric data is less than 10%, the processor 115 turns on the LED corresponding to the numeric key '1', and the accumulation rate of the accumulated biometric data is 10% or more and less than 20%. At this time, the processor 115 further lights the LED corresponding to the number key '2', and when the accumulation rate of the accumulated biometric data is 20 or more and less than 30%, the processor 115 turns on the LED corresponding to the number key '3'. In a more lit method, as the accumulation rate of biometric data (or the amount of memory used) increases, the processor 115 may increase the number of numeric keys lit by the LED.

As another example, when the accumulation rate of the accumulated biometric data is less than 30%, the processor 115 turns on LEDs corresponding to the numeric keys '1', '2', and '3' arranged in the first row, and , When the accumulation rate of the accumulated biometric data is 30% or more and less than 60%, the processor 115 includes numeric keys '4' arranged in the second row. LEDs corresponding to '5' and '6' are turned on, and when the accumulation rate of the accumulated biometric data is 60% or more and less than 90%, the processor 115 displays the numeric keys '7' arranged in the third row. When the LEDs corresponding to '8' and '9' are lit, and the accumulation rate of the accumulated biometric data is 100%, the processor 115 displays the numeric keys'*' arranged in the fourth row. LEDs corresponding to '0' and'#' can be turned on.

As described above for example, the processor 115 quantitatively calculates the accumulation rate of the accumulated biometric data (the amount of memory allocated for each user) by using one key or at least two keys among the keys included in the keypad 120. (Or numbers).

Whenever the accumulation rate of the accumulated biometric data increases, the processor 115 may adjust the number of keys to display the accumulation rate among keys arranged on the keypad 120.

As described above, the usage of the memory 130 allocated to each user may be mapped to an accumulation rate of the accumulated biometric data. That is, when the amount of the memory 130 allocated to a specific user is 78%, the accumulation rate of the accumulated biometric data may be 78%.

The processor 115 or the computer program executed in the processor 115 can determine whether the memory capacity of the memory 130 allocated for each user is filled out of the total memory capacity or whether the accumulation rate of the accumulated biometric data is 100%. Yes (S120).

When it is determined that the memory capacity of the memory 130 allocated to the user registering the current fingerprint has not been filled, or when it is determined that the accumulation rate of the accumulated biometric data is less than 100% (NO in S120), the processor 115 The accumulation rate of the accumulated biometric data through the keypad 120 is displayed according to the control of the user, so that the user has the accumulated biometric data until the memory capacity is full (or is considered to be full within the tolerance range) or The biometric information registration operation of registering a fingerprint in the digital door lock 100A may be repeatedly performed until the accumulation rate of data reaches 100% (or a range considered to be 100% within an allowable error range).

When the memory capacity of the memory 130 allocated to the user who is currently enrolling a fingerprint is full or when the accumulation rate of the accumulated biometric data is 100% (YES in S120), the processor 115 performs the accumulated biometric data (or The fingerprint) is stored (or registered) in the memory 130 (S125). When the fingerprint is registered in the memory 130 of the digital door lock 100A through this process, when the locking device 150 of the door lock 100A is released using the fingerprint, there is an effect of increasing the fingerprint recognition success rate.
