Description
Technical Field
The invention relates to the technical field of door locks, in particular to a method for setting temporary fingerprints by authorization.
Background
The off-line (without network support) remote unlocking mode (for the guest or tenant needing temporary use) in the current market combines the management password and the standard time to generate a deadline password containing the current time and the deadline time. The time limit code is input into the lock, and the lock can be unlocked if the time and the management code are correct.
This scheme has a certain disadvantage that the password length of the time limit password is relatively long, generally more than 10 digits, because the time limit password contains time and a management password. When the user uses the time limit password, the user needs to have good memory or take out the password for comparison and input every time the user uses the time limit password, so that the user is inconvenient to use the time limit password, and the use experience of the user is influenced.
Disclosure of Invention
In view of the above, the present invention provides a method for authorizing setting of a temporary fingerprint.
In order to solve the technical problems, the technical scheme of the invention is as follows: a method of authorizable settings of a temporary fingerprint, comprising:
step 1: generating two groups of time limit passwords which are a time limit password I and a time limit password II respectively at the server side according to the combination of the current standard time and the input management password, and entering the step 2;
step 2: inputting a time limit password III at a user terminal, judging the time limit password III at the user terminal, judging whether the time limit password is a time limit password I or a time limit password II, entering a step 3 when the time limit password III is consistent with the time limit password I, entering a step 4 when the time limit password III is consistent with the time limit password II, and keeping a door lock closed when the time limit password III is inconsistent with the time limit password I and the time limit password II;
and step 3: judging the timeliness of the time limit password III, and when the time limit password III is in a specified time limit, opening the door lock, otherwise, keeping the door lock closed;
and 4, step 4: judging the timeliness of the time limit password III, entering the step 5 when the time limit password III is in a specified time limit, otherwise, keeping the door lock closed;
and 5: starting temporary fingerprint password registration, enabling a user to record and store a fingerprint to a user side to obtain a preset fingerprint password I, and entering step 6;
step 6: the user inputs a fingerprint password II at a fingerprint input end of the user end, the fingerprint password II is judged at the user end, when the fingerprint password II is consistent with a preset fingerprint password I, the timeliness of the fingerprint password II is judged, when the fingerprint password II is within a specified time limit, the step 7 is carried out, otherwise, the door lock is kept closed;
and 7: and judging the timeliness of the fingerprint password II, and when the fingerprint password II is in a specified period, opening the door lock, otherwise, keeping the door lock closed.
Further, the term time is counted in days.
Preferably, the combination of the standard time and the management password in step 1 is integrated and encrypted into a ciphertext, and then the ciphertext is converted into a multi-bit 10-system deadline password I and a multi-bit 10-system deadline password II.
Further, when the time limit password iii and the time limit password i or the time limit password ii in step 2 are judged, decryption operation needs to be performed on the time limit password iii, and consistency judgment needs to be performed on the time limit password iii and the time limit password i and the time limit password ii before the encryption is integrated.
The invention has the technical effects that: through producing two sets of different deadline passwords, a set of deadline password can realize normally unblanking in the regulation deadline, and another group of deadline password can set up interim authorized fingerprint, recycles interim authorized fingerprint and unblanks at the fingerprint of deadline, has solved the trouble that all needs to input many passwords at every turn, and convenience of customers' use has promoted user experience more.

Detailed Description
The following detailed description of the embodiments of the present invention is provided in order to make the technical solution of the present invention easier to understand and understand.
Example 1:
as shown in fig. 1-2, a method of authoritatively setting a temporary fingerprint, comprising:
step 1: the management password comprises a user preset password and a selected deadline time which is counted in units of days according to the combination of the current standard time and the input management password at the server, the input user preset password, the current RTC timestamp and the set deadline time are taken, the ciphertext is integrated and encrypted into a ciphertext (integrated into password data), the ciphertext is converted into two sets of deadline passwords with 10 systems of multiple bits (generally 10 bits), the two sets of deadline passwords are respectively a deadline password I and a deadline password II and are published to the user, and the step 2 is entered;
step 2: inputting a deadline password III at a user end, carrying out decryption operation on the deadline password III at the user end, judging whether the deadline password III is consistent with an encrypted ciphertext of a deadline password I or a deadline password II, entering a step 3 when the deadline password III is consistent with the deadline password I, entering a step 4 when the deadline password III is consistent with the deadline password II, and proving that the input deadline password III is wrong when the deadline password III is inconsistent with the deadline password I and the deadline password II, closing a door lock and exiting an unlocking program;
and step 3: judging the timeliness of the time limit password III, judging the time limit contained in the time limit password III after decryption operation, opening the door lock when the time limit password III is in a specified time limit, otherwise, keeping the door lock closed, namely the input time limit password III exceeds the set time limit, and exiting the unlocking program;
and 4, step 4: judging the timeliness of the time limit password III, judging the time limit contained in the time limit password III after decryption operation, entering a step 5 when the time limit password III is in a specified time limit, otherwise, keeping the door lock closed, namely the input time limit password III exceeds the set time limit, and exiting the unlocking program;
and 5: starting temporary fingerprint password registration, enabling a user to input and store fingerprints to a user side to obtain a preset fingerprint password I, entering step 6, inputting a plurality of fingerprint passwords for multiple times, generally not more than 10 fingerprint passwords, by inputting a time limit password II corresponding to a time limit password III for multiple times, and then obtaining a plurality of preset fingerprint passwords;
step 6: the user inputs a fingerprint password II at a fingerprint input end of the user end, the fingerprint password II is judged at the user end, when the fingerprint password II is consistent with a preset fingerprint password I, the timeliness of the fingerprint password II is judged, when the fingerprint password II is within a specified time limit, the step 7 is carried out, otherwise, the door lock is kept closed;
and 7: and judging the timeliness of the fingerprint password II, and when the fingerprint password II is in a specified period, opening the door lock, otherwise, keeping the door lock closed, and exiting the unlocking program.
The term password corresponding to the term password i can be used an unlimited number of times within a predetermined time, but the predetermined time is in units of days.
The deadline password corresponding to the deadline password II can be called a deadline fingerprint authorization code, after the deadline fingerprint authorization code is generated, 10 fingerprints can be recorded at most in a specified time, but the specified time is in a day cooperation unit; the method is mainly used in occasions such as short renting or long renting apartments and the like, and is convenient for a user to use for multiple times.
Examples of the cryptosynthesis schemes of the deadline code I or the deadline code II include:
integrating the input user preset password, the timestamp of the current RTC and the set expiration time into password data: 4 bytes, 32 bits;
cipher text is 32 bits of data; 31. 30 two bits represent the password class;
00 temporary password
10 deadline fingerprint authorization code
11 deadline password
0-29Bit represents the quotient of division 4 of the timestamp of the current RTC, i.e., a timestamp in units of 4 seconds:
measuring and calculating: 30bit =0x3fffffff = (1073741823 × 4) seconds
15-29 bits represent the starting time and the time stamp in days;
0-14 represent the expiration time, time stamp in 1 hour;
measuring and calculating: starting time: 15bit =0x00007fff =32767 days/365 =89 years
Starting time: time of onset + (15 bit =0x00007fff =32767/24=1365 days/365) 3 years
