Detailed Description
The application provides a safety protection method of intelligent coded lock, record the fingerprint information of unblanking personnel to detect the condition of unblanking, in time report to the police when detecting the unusual, the fingerprint information of record can be used to trace back unusual unblanking personnel simultaneously.
Referring to fig. 1, a flow chart of a security protection method of an intelligent coded lock according to an embodiment of the present application includes the following steps:
s101: acquiring recorded fingerprint information, recording the fingerprint information and a first time stamp when the fingerprint information is recorded, and starting a password input module, wherein the fingerprint information is used for tracing unlocking personnel;
s102: the password input module receives the input unlocking password, the unlocking password is verified, and if the verification result is that the password is correct, the intelligent coded lock is controlled to be unlocked; if the verification result is that the password is wrong, the intelligent password lock is kept closed; recording verification information corresponding to an unlocking password, wherein the verification information comprises a verification result and a second timestamp when the verification result is generated;
s103: judging whether the recorded verification information has an abnormal event or not, if so, determining fingerprint information corresponding to the abnormal event according to the first timestamp and the second timestamp, and triggering an abnormal response mechanism according to the fingerprint information corresponding to the abnormal event.
Regarding step S101, the intelligent coded lock obtains fingerprint information recorded by an unlocking person through a fingerprint collection device, where the fingerprint collection device may be a device capable of collecting fingerprints to obtain fingerprint image data, such as an optical fingerprint collection device, a radio frequency fingerprint collection device, a thermal fingerprint collection device, a semiconductor capacitance fingerprint collection device, and a semiconductor pressure fingerprint collection device.
The fingerprint information collected by the fingerprint collecting device is the fingerprint information of the unlocking personnel, can be used for tracing the identity of the unlocking personnel to which the fingerprint information belongs, and can be fingerprint image data or characteristic data of the fingerprint image after being extracted by an algorithm.
When the fingerprint information is recorded, a first timestamp is recorded when the fingerprint information is recorded, and the first timestamp is used for marking the time of recording the fingerprint information, in this embodiment, the time when the fingerprint information is recorded, and in other embodiments, the time when the fingerprint information is verified to be legal after the fingerprint information is recorded. The recorded fingerprint information and the first timestamp when the fingerprint information is recorded can be stored in a local or cloud server. If the fingerprint information is stored in the cloud server, the intelligent coded lock binds and uploads the fingerprint information and the first timestamp to the cloud server through the communication module for storage.
After the fingerprint information and the first time stamp are recorded, a password input module is started, and the input unlocking password is received through the password input module.
The password input module is a device for inputting an unlocking password, which can be a touch screen type or key type password input device, and can also be other devices for inputting the unlocking password, in one embodiment, the password input module can also be a software function module for receiving the unlocking password in the intelligent password lock, the operation of starting the password input module is to receive the unlocking password through the corresponding software function module, and the operation of closing the password input module is to not receive the unlocking password through the corresponding software function module.
In this embodiment, need type in its fingerprint information when the personnel of unblanking unblanked, intelligent trick lock has recorded the fingerprint information that the personnel of unblanking input and the first timestamp when fingerprint information is in, when later stage detects unusual, alright trace back the personnel of unblanking that corresponds.
Referring to fig. 2, in one embodiment, after the acquiring the entered fingerprint information S1010, the method further includes:
s1011: verifying whether the fingerprint information is legal or not; if the fingerprint information is legal, executing the steps of recording the fingerprint information and a first time stamp when the fingerprint information is recorded and starting a password input module; if the fingerprint information is illegal, the fingerprint information is not recorded and the password input module is not started.
In order to ensure that the fingerprint information entered by the unlocking person is true fingerprint information of a person, rather than impersonating the fingerprint information by using a foreign object such as a silica gel fingerprint mold, the fingerprint information needs to be verified for authenticity, whether the fingerprint information is the fingerprint information entered by the finger of the true person or not is verified, and if yes, the fingerprint information is verified to be legal.
There are various ways to verify the authenticity of the fingerprint information, for example, detecting the temperature of the touching object when inputting the fingerprint information, if the touching object is a real finger, the detected temperature should be in the normal temperature range of the human body, or the collected fingerprint information may be analyzed by an algorithm to determine whether the fingerprint information is the real fingerprint information.
In one embodiment, the temperature of the touching object on the fingerprint acquisition device of the intelligent coded lock is detected through the infrared temperature measuring device, when the temperature of the touching object is within a preset temperature threshold range, for example, the normal body temperature range of a person, for example, 34-40 ℃, the person is verified to be legal, and otherwise, the person is not legal.
In another embodiment, the fingerprint information is analyzed based on a fingerprint image quality analysis algorithm to obtain a quality parameter, and when the quality parameter is greater than a preset quality threshold, the fingerprint information is verified to be legal, otherwise, the fingerprint information is not legal. In the prior art, various fingerprint image quality analysis algorithms are used for analyzing and judging the quality and the effectiveness of fingerprint images, and one or a plurality of algorithms can be selected according to conditions to perform fingerprint image quality analysis on the fingerprint information. In this embodiment, the fingerprint image quality analysis algorithm can determine whether the collected fingerprint information is the fingerprint information of the actual fingerprint of the person, and meanwhile, the recorded fingerprint information can be ensured to have higher quality through the preset quality threshold value, so that the fingerprint image quality analysis algorithm can be used for tracing the corresponding unlocking person.
Of course, in another embodiment, the two verification methods described above may also be combined: and detecting the temperature of a touch object on a fingerprint acquisition device of the intelligent coded lock through an infrared temperature measuring device, analyzing the fingerprint information based on a fingerprint image quality analysis algorithm to obtain a quality parameter, and verifying that the fingerprint information is legal when the temperature of the touch object is within a preset temperature threshold range and the quality parameter is greater than a preset quality threshold, or else, verifying that the fingerprint information is illegal.
In this embodiment, the fingerprint acquisition device and/or the infrared temperature measurement device are/is connected with a processor of the intelligent coded lock, the processor receives the fingerprint information and/or the temperature data and verifies the fingerprint information, and if the fingerprint information is verified to be legal, the step of recording the fingerprint information and a first timestamp when the fingerprint information is recorded is executed and starting a password input module; if the fingerprint information is verified to be illegal, the fingerprint information is not recorded and the password input module is not started. In an embodiment, if the fingerprint information is not legal, a prompt for re-entering the fingerprint can be sent, and the prompt can be in a mode of voice broadcasting, display screen displaying and the like.
For step S102, the unlocking password input by the unlocking personnel is received through the password input module, the unlocking password is verified, and if the verification result is that the password is correct, the unlocking of the intelligent coded lock is controlled; if the verification result is that the password is wrong, the intelligent password lock is kept closed; after each verification of the unlocking password, verification information corresponding to the unlocking password is recorded, wherein the verification information comprises a verification result and a second timestamp when the verification result is generated.
The verification of the unlocking password means that the received unlocking password is matched with an unlocking password preset by the intelligent coded lock, and if the received unlocking password is matched with the preset unlocking password, the verification result is that the password is correct; if not, the verification result is a password error.
In an alternative embodiment, the step of receiving the input unlocking password through the password input module includes:
receiving an input unlocking password through the password input module within a preset time after the password input module is started; and closing the password input module when the preset time is exceeded after the password input module is started.
The preset time is used for limiting a time interval in which an unlocking person can input an unlocking password, and can be set according to actual needs, for example, 30 seconds, 60 seconds or 2 minutes, and in one example, the unlocking password input by the unlocking person is received through the password input module within 30 seconds after the password input module is started; and closing the password input module when the time exceeds 30 seconds after the password input module is started.
After the password input module is closed, the input unlocking password is not received any more, and an unlocking person needs to input fingerprint information again through the step S101 to open the password input module again.
By limiting the time for which the password input module is kept on, the password input module is prevented from being always on or kept on for too long, so that other people can input unlocking passwords without inputting fingerprint information.
In another alternative embodiment, the step of receiving the input unlocking password through the password input module includes:
after the password input module is started, the password input module receives the input unlocking password, and when the number of times of receiving the input unlocking password reaches the preset receiving number, the password input module is closed.
The preset number of times of receiving is used for limiting the limited number of times of unlocking passwords which can be input by an unlocking person after the password input module is started, and the limited number of times of unlocking passwords can be 1 time or more than 1 time, in one example, after the password input module is started, the unlocking passwords input by the password input module are received, and when the number of times of receiving the input unlocking passwords reaches 5 times in an accumulated manner, the password input module is closed.
The password input module is prevented from being always started and receiving the unlocking password by limiting the receiving times of the unlocking password after being started, so that other people can input the unlocking password without inputting fingerprint information.
Of course, in another embodiment, the step of receiving, by the password input module, the input unlocking password may be combined with the steps of the two alternative embodiments, including:
and receiving an input unlocking password through the password input module within a preset time after the password input module is started, and closing the password input module when the number of times of receiving the input unlocking password reaches a preset receiving number or exceeds the preset time after the password input module is started.
And through the limitation of the preset time and the preset receiving times, unlocking personnel can only input the unlocking password in a limited time and a limited number of times after starting the password input module each time.
For step S103, since the complexity of the unlocking password set by the intelligent coded lock is limited, in order to prevent an illegal person from unlocking by unauthorized means, for example, after a trial and error is performed by inputting the unlocking password multiple times, the correct unlocking password may be used to successfully unlock finally.
The abnormal event refers to the recorded verification information having abnormal conditions, and is specifically judged by a preset abnormal detection method.
In an alternative embodiment, the step of determining whether the recorded verification information has an abnormal event includes:
judging whether a plurality of verification results which are continuous in time are password errors according to the verification results in the recorded verification information and the corresponding second time stamp, and judging whether the recorded verification information has abnormal events if the number of the password errors exceeds a first preset number threshold.
The several verification results which are continuous in time are all password errors, which means that the verification results of unlocking passwords which are input successively from front to back are all password errors, and the time interval is not limited, for example, the first password error and the second password error can be separated by any long time, and the two password errors can occur successively as long as the condition that the verification result is that the password is correct is not existed in the middle.
The first preset time threshold may be set according to circumstances, for example, may be set to 3 times, and then when the number of time-continuous verification results are all password errors and the number of password errors exceeds 3 times, it is determined that an abnormal event exists.
In general, the unlocking password input by the unlocking personnel for many times is wrong, so that the unlocking personnel has a larger suspicion of abnormal unlocking, whether the number of times of continuous many times of password errors exceeds a first preset number threshold value is judged, and if yes, the recorded verification information has an abnormal event. In this embodiment, when the unlocking password input by the unlocking person for several times is a password error and the number of password errors exceeds the preset number of times, no matter how long the time is between, for example, the unlocking person may try to unlock the password once at intervals, as long as the number of accumulated continuous multiple password errors exceeds the first preset number threshold, the abnormal event will be judged to exist, so that the unlocking person is effectively prevented from inputting the unlocking password for trial and error at a certain time interval and thereby bypasses the detection of the detection method based on the operation frequency judgment abnormality.
In an alternative embodiment, the step of determining whether the recorded verification information has an abnormal event includes:
acquiring a plurality of verification information which are continuous in time, and acquiring a verification information sequence; counting the number of the verification information in the verification information sequence in a preset sliding time window, judging whether the number of the verification information exceeds a second preset time threshold, and if so, judging that the recorded verification information has an abnormal event.
In general, if the unlocking personnel inputs the unlocking password too frequently, the unlocking personnel has a larger suspicion of abnormal unlocking, and if the number of the verification information in the sliding time window exceeds the second preset frequency threshold, the operation is considered to be too frequent, and if the number of the verification information exceeds the second preset frequency threshold, the recorded verification information can be judged to have an abnormal event.
The verification information sequence is formed by arranging the plurality of verification information according to the corresponding second time stamps in time sequence.
The sliding time window refers to a slidable time range, and in this embodiment, the sliding time window is within a preset time range from the time when the verification result is generated to the time before the time, for example, the sliding time window may be within the last 2 minutes when the verification result is generated after the unlocking person inputs the unlocking password.
The second preset number of times threshold may be set according to circumstances, for example, may be set to 5 times, and then, when the number of pieces of verification information in the verification information sequence in the sliding time window exceeds 5, it is determined that an abnormal event exists.
In an alternative embodiment, the step of determining whether the recorded verification information has an abnormal event includes:
counting the number of the verification information recorded in a preset time period, judging whether the number of the verification information recorded in the time period exceeds the normal verification times of the time period, and if so, judging that the recorded verification information has abnormal events; the normal verification times are obtained through big data analysis according to the verification information of the history record.
In this embodiment, the normal verification times of different time periods are obtained through big data analysis according to the verification information of the history record, specifically, the normal unlocking verification times of different time periods of different seasons, holidays and workdays are included.
The unlocking conditions are different in different seasons, holidays, workdays and different time periods of each day, for example, the time periods and times of unlocking on one of the different seasons and holidays are generally different, the time periods and times of unlocking on one of the holidays and the workdays are possibly different, rules of the unlocking on the basis of the verification information recorded in the history can be obtained through big data analysis, the normal unlocking verification times of the different time periods of the different seasons, holidays and workdays are obtained, and when the number of unlocking password verification information input by an unlocking person in the preset time period exceeds the normal verification times of the time period, abnormal events are judged.
Of course, the abnormality detection methods of any two or three of the above embodiments may be combined at the same time, and the determination may be performed at the same time. The abnormality detection methods of the three embodiments can detect abnormality for various possible abnormal unlocking situations, and can timely detect abnormal operations of unlocking by an abnormal unlocking person through blind guessing trial and error.
In this embodiment, if it is determined that the recorded verification information has an abnormal event, fingerprint information corresponding to the abnormal event is determined according to the first timestamp and the second timestamp, and an abnormal response mechanism is triggered according to the fingerprint information corresponding to the abnormal event.
The fingerprint information corresponding to the abnormal event is the fingerprint information recorded before the moment when the abnormal event is judged to exist, generally speaking, the fingerprint information corresponding to the first timestamp which is before the second timestamp of the verification information of the unlocking password when the abnormal event is judged to exist and has the time closest to the second timestamp, but in some special cases, for example, when an abnormal unlocking person performs unlocking, the recorded verification information is not judged to exist the abnormal event, and the current verification information is not caused to be judged to exist the abnormal event based on the verification information recorded before when other normal persons perform normal unlocking, so in some embodiments, the fingerprint information corresponding to the abnormal event can also be a plurality of fingerprint information recorded before the moment when the abnormal event is judged to exist, and the real abnormal unlocking person can be analyzed based on the plurality of fingerprint information.
In one embodiment, the step of determining whether the recorded verification information has an abnormal event includes:
judging whether the verification information recorded in the period has an abnormal event or not according to a preset period.
In the scene of temporary unlocking, an administrator configures a temporary unlocking password and the effective time period and the effective use times of the temporary unlocking password for the intelligent coded lock, so that temporary unlocking personnel such as a nurse, a temporary cleaning personnel or a home guest can use the temporary unlocking password to unlock in the set effective time period and the effective use times. In this embodiment, the anomaly detection is performed for a preset period of time, and the anomaly detection may not be performed for other times, where the period of time for performing the anomaly detection may be set by an administrator.
In one embodiment, the exception response mechanism includes: and pushing abnormal information to a preset alarm receiver, wherein the abnormal information comprises the fingerprint information, and the abnormal unlocking personnel can be traced through the fingerprint information.
The alarm receiver is a preset relevant person for receiving the abnormal information, such as a residence owner, a residence manager or public security bureau, a regional committee, a property, a neighbor and the like.
