Detailed Description
The application provides a safety protection method of an intelligent coded lock, which records fingerprint information of unlocking personnel, detects the unlocking condition, timely gives an alarm when detecting abnormity, and meanwhile, the recorded fingerprint information can be used for tracing the abnormal unlocking personnel.
Referring to fig. 1, which is a schematic flowchart of a security protection method of an intelligent combination lock according to an embodiment of the present application, including the following steps:
s101, acquiring input fingerprint information, recording the fingerprint information and a first timestamp when the fingerprint information is input, and starting a password input module, wherein the fingerprint information is used for tracing an unlocking person;
s102, receiving an input unlocking password through the password input module, verifying the unlocking password, and controlling the intelligent coded lock to unlock if the verification result is that the password is correct; if the verification result is that the password is wrong, the intelligent password lock is kept closed; recording verification information corresponding to the 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 time stamp and the second time stamp, and triggering an abnormal response mechanism according to the fingerprint information corresponding to the abnormal event.
Regarding step S101, the intelligent combination lock obtains the fingerprint information entered by the unlocking staff through the fingerprint collecting device, which may be an optical fingerprint collecting device, a radio frequency fingerprint collecting device, a thermal sensitive fingerprint collecting device, a semiconductor capacitance fingerprint collecting device, a semiconductor pressure sensitive fingerprint collecting device, and the like, capable of collecting fingerprints to obtain fingerprint image data.
The fingerprint information collected by the fingerprint collecting device is fingerprint information of an unlocking person, can be used for tracing the identity of the unlocking person to which the fingerprint information belongs, and can be fingerprint image data or characteristic data obtained by extracting a fingerprint image through an algorithm.
When recording the fingerprint information, record the first time stamp when the fingerprint information was recorded, first time stamp is used for marking the time of fingerprint information recording, in this embodiment, it is the time when the fingerprint information was recorded, in other embodiments, also can be after recording the fingerprint information, the time when the fingerprint information was verified to be legal. The recorded fingerprint information and the first timestamp of the fingerprint information when being recorded can be stored in a local or cloud server. If the fingerprint information and the first timestamp are stored in the server at the cloud end, the intelligent coded lock binds and uploads the fingerprint information and the first timestamp to the server at the cloud end through a communication module for storage.
After the fingerprint information and the first timestamp are recorded, a password input module is started, and an input unlocking password is received through the password input module.
In one embodiment, the password input module may also be a software function module in the intelligent password lock for receiving the unlocking password, the operation of opening 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 receive the unlocking password without the corresponding software function module.
In this embodiment, need type its fingerprint information when the person of unblanking unblanks, intelligent trick lock has recorded the fingerprint information that the person of unblanking types and first time stamp when the fingerprint information was types, when the later stage detected unusually, alright in order to trace back the person of unblanking who corresponds.
Referring to fig. 2, in an 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 timestamp when the fingerprint information is recorded and starting a password input module; and if the fingerprint information is illegal, not recording the fingerprint information and not starting a password input module.
In order to ensure that the fingerprint information input by an unlocking person is the real fingerprint information of a person, rather than being faked by using a foreign body such as a silica gel fingerprint mold, authenticity verification needs to be carried out on the fingerprint information, whether the fingerprint information is the fingerprint information input by the finger of the real 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 a touch object when inputting the fingerprint information, and if the touch object is a real finger, the detected temperature should be within the normal temperature range of the human body, or analyzing the acquired fingerprint information through an algorithm to determine whether the fingerprint information is real fingerprint information.
In one embodiment, the temperature of a touch object on the fingerprint acquisition device of the intelligent coded lock is detected through an infrared temperature measurement device, and when the temperature of the touch object is within a preset temperature threshold range, for example, within a normal body temperature range of a person, such as 34-40 ℃, the verification is legal, otherwise, the verification is illegal.
In another embodiment, the fingerprint information is analyzed based on a fingerprint image quality analysis algorithm to obtain a quality parameter, when the quality parameter is greater than a preset quality threshold, the fingerprint information is verified to be legal, otherwise, the fingerprint information is illegal. In the prior art, a plurality of fingerprint image quality analysis algorithms are used for analyzing and judging the quality and effectiveness of fingerprint images, and one or more algorithms can be selected according to conditions to analyze the quality of the fingerprint images on the fingerprint information. In this embodiment, whether the acquired fingerprint information is fingerprint information of a human real fingerprint can be judged through a fingerprint image quality analysis algorithm, and meanwhile, the recorded fingerprint information can be ensured to have higher quality through the preset quality threshold value, so that the fingerprint information can be used for tracing corresponding unlocking personnel.
Of course, in another embodiment, the above two verification methods may also be combined: the temperature of a touch object on a fingerprint acquisition device of the intelligent coded lock is detected through an infrared temperature measuring device, the fingerprint information is analyzed based on a fingerprint image quality analysis algorithm, a quality parameter is obtained, when the temperature of the touch object is within a preset temperature threshold range and the quality parameter is larger than a preset quality threshold, the fingerprint information is verified to be legal, and otherwise, the fingerprint information is illegal.
In this embodiment, the fingerprint acquisition device and/or the infrared temperature measurement device is connected to a processor of an intelligent coded lock, the processor receives and verifies the fingerprint information and/or the temperature data, and if the fingerprint information is verified to be legal, the step of recording the fingerprint information and a first timestamp during entry of the fingerprint information and starting a password input module is executed; and 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 verified to be illegal, a prompt for re-inputting the fingerprint can be sent, and the prompt can be in a voice broadcasting mode, a display screen display mode and the like.
For step S102, an unlocking password input by an unlocking person is received through the password input module, the unlocking password is verified, and if the verification result is that the password is correct, the intelligent coded lock is controlled to unlock; if the verification result is that the password is wrong, the intelligent password lock is kept closed; and recording verification information corresponding to the unlocking password after verifying the unlocking password every time, wherein the verification information comprises a verification result and a second timestamp when the verification result is generated.
The verification of the unlocking password refers to matching the received unlocking password 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 optional embodiment, the step of receiving the input unlocking password through the password input module comprises:
receiving an input unlocking password through the password input module within a preset time after the password input module is started; and when the preset time is exceeded after the password input module is opened, closing the password input module.
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 opened; and closing the password input module when the time exceeds 30 seconds after the password input module is opened.
After the password input module is closed, the input unlocking password is not received any more, and the unlocking person needs to enter the fingerprint information again through the step S101 to open the password input module again.
The method and the device have the advantages that the time for maintaining the opening of the password input module is limited, so that the password input module is prevented from being opened all the time or being opened for too long, and other personnel can input the unlocking password without inputting fingerprint information.
In another optional embodiment, the step of receiving the input unlocking password through the password input module comprises:
after the password input module is opened, the input unlocking password is received through the password input module, and when the accumulated times of receiving the input unlocking password reaches the preset receiving times, the password input module is closed.
The preset receiving times are used for limiting the limited times of the unlocking password which can be input by an unlocking person after the password input module is opened, and can be 1 time or more than 1 time.
The password input module is prevented from being opened all the time and receiving the unlocking password through the limitation of the receiving times of the unlocking password after the password input module is opened, so that other personnel can input the unlocking password without inputting fingerprint information.
Of course, in another embodiment, the step of receiving the input unlocking password through the password input module may combine the steps of the two alternative embodiments, including:
and receiving the input unlocking password through the password input module within a preset time after the password input module is opened, and closing the password input module when the accumulated times of receiving the input unlocking password reach the preset receiving times or the preset time is exceeded after the password input module is opened.
And through the limitation of the preset time and the preset receiving times, the unlocking personnel can only input the unlocking password within the limited time and the limited times after unlocking the password input module every time.
For step S103, since the complexity of the unlocking password set by the intelligent combination lock is limited, in order to prevent unauthorized unlocking by an illegal person, for example, after a number of trial and error attempts of the unlocking password are continuously input, it is possible that a correct unlocking password is finally successfully unlocked, the present application first determines whether an abnormal event exists according to the recorded verification information, and if an abnormal event exists, determines fingerprint information corresponding to the abnormal event according to the first timestamp and the second timestamp, and triggers an abnormal response mechanism according to the fingerprint information corresponding to the abnormal event.
The abnormal event refers to the recorded abnormal condition of the verification information, and is specifically judged by a preset abnormal detection method.
In an optional embodiment, the step of determining whether there is an abnormal event in the recorded verification information includes:
and judging whether a plurality of verification results which are continuous in time are all password errors according to the recorded verification results in the verification information and the corresponding second time stamps, and judging whether the recorded verification information has abnormal events if the number of times of the password errors exceeds a first preset number threshold.
The plurality of verification results which are continuous in time are all password errors, which means that the verification results of the unlocking passwords input in succession are all password errors, and are not limited by time intervals, for example, any time can be left between the first password error and the second password error, and as long as the verification result does not exist in the middle, the two password errors occur in succession.
The first preset time threshold may be set according to a situation, for example, may be set to 3 times, and then, when a plurality of verification results that are continuous in time are all password errors and the number of times of the password errors exceeds 3 times, it is determined that an abnormal event exists.
Generally speaking, the unlocking passwords input by the unlocking personnel continuously for multiple times are all errors, so that the unlocking personnel has a greater suspicion of abnormal unlocking, and whether the times of the continuous multiple password errors exceed a first preset time threshold value is judged, and if yes, the recorded verification information is judged to have an abnormal event. In this embodiment, when the unlocking password input by the unlocking person for several times before and after is the password error and the number of times of the password error exceeds the preset number of times, no matter how long the interval is, for example, the unlocking person may try to unlock the password once at intervals, as long as the accumulated number of times of continuous multiple password errors exceeds the first preset number threshold, the unlocking password is judged to be an abnormal event, so that the unlocking person is effectively prevented from inputting the unlocking password at a certain time interval to try and error, and the detection based on the detection method for judging the abnormality based on the operation frequency is bypassed.
In an optional embodiment, the step of determining whether there is an abnormal event in the recorded verification information includes:
acquiring a plurality of pieces of verification information which are continuous in time to obtain 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 value, and if so, judging that the recorded verification information has an abnormal event.
Generally speaking, if the unlocking password is input too frequently by an unlocking person, the unlocking person has a greater suspicion of abnormal unlocking, and by judging whether the number of the verification information in the sliding time window exceeds the second preset time threshold value, if the number exceeds the second preset time threshold value, the operation is considered to be too frequent, 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 a time when the verification result is generated to a time before the time, for example, may be within the last 2 minutes when the verification result is generated after the unlocking person inputs the unlocking password.
The second preset time threshold may be set according to a situation, for example, may be set to 5 times, and then, when the number of the verification information in the verification information sequence in the sliding time window exceeds 5, it is determined that an abnormal event exists.
In an optional embodiment, the step of determining whether there is an abnormal event in the recorded verification information 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 an abnormal event; and the normal verification times are obtained by analyzing big data according to the verification information of the historical records.
In this embodiment, the normal verification times of different time periods, specifically, the normal unlocking verification times of different time periods including different seasons, holidays, and workdays, are obtained through big data analysis according to the verification information of the history record.
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 required in one of the different seasons and holidays are generally different, the time periods and times of unlocking required in one of the holidays and workdays are possibly different, the rules of the verification information based on the historical records can be obtained through big data analysis, the verification times of normal unlocking in different seasons, holidays and different time periods of the workdays are obtained, and when the number of the verification information of the unlocking password input by the unlocking person in the preset time period exceeds the normal verification times of the time period, the abnormal event is judged to exist.
Of course, the abnormality detection methods of any two or three of the above embodiments may be combined at the same time to perform the determination. The abnormality detection method of the three embodiments can detect abnormality for various possible abnormal unlocking situations, and can detect abnormal operation of unlocking by abnormal unlocking personnel through blind guessing and trial and error in time.
In this embodiment, if it is determined that the recorded verification information has an abnormal event, the fingerprint information corresponding to the abnormal event is determined according to the first time stamp and the second time stamp, 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 fingerprint information recorded before the time when the abnormal event exists is judged, and generally speaking, the fingerprint information corresponds to a first timestamp which is before a second timestamp and has the closest time distance from the second timestamp of the verification information of the unlocking password when the abnormal event exists, but under some special conditions, for example, when an abnormal unlocking person unlocks, the recorded verification information is not judged to have the abnormal event, and the current verification information is judged to have the abnormal event based on the previously recorded verification information until other normal persons normally unlock, so that in some embodiments, the fingerprint information corresponding to the abnormal event can also be a plurality of fingerprint information recorded before the time when the abnormal event exists is judged, 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:
and judging whether the verification information recorded in the period has an abnormal event or not according to a preset period.
