Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.
Example one
Fig. 1 is a flowchart of a method for ensuring stability of fingerprint data according to an embodiment of the present invention. The method of the embodiment can be executed by a device for ensuring the stability of the fingerprint data of the terminal, and the device can be realized by software and/or hardware and is integrated in the terminal capable of loading the fingerprint data. As shown in fig. 1, the method includes:
step 101, two groups of fingerprint data for executing the same function are pre-stored, wherein one group of fingerprint data is used as main fingerprint data, and the other group of fingerprint data is used as backup fingerprint data.
In this embodiment, the main fingerprint data is user fingerprint data collected by the terminal for executing a certain function, and the number of the fingerprint data is at least one. The backup fingerprint data is data obtained by backing up the main fingerprint data. A certain function may be to unlock a screen, pay, or open an application, and the like, and this embodiment is not limited. The terminal can be a mobile phone, a tablet computer, or a terminal with a fingerprint function such as MP 4.
Illustratively, two groups of fingerprint data for executing the same function are prestored, and the specific implementation process is as follows: first fingerprint data is collected, and it is confirmed that the first fingerprint data can be loaded and normally used. After a terminal collects first fingerprint data, feature extraction is carried out on the first fingerprint data and an encrypted file is generated through encryption, the encrypted file needs to be decrypted and loaded before the first fingerprint data is used for preventing the collected first fingerprint data from being used, whether the first fingerprint data can be normally used or not is judged through a loading result, and after the first fingerprint data can be loaded and normally used, the first fingerprint data can be stored as main fingerprint data and the main fingerprint data can be backed up as backup fingerprint data. The first fingerprint data may be stored as the main fingerprint data by replacing any fingerprint data in the main fingerprint data, replacing fingerprint data with low use frequency in the main fingerprint data, or storing the first fingerprint data into the main fingerprint data. And if the first fingerprint data fails to be loaded, deleting all fingerprint data, prompting the user to re-input the fingerprint, and loading and judging the re-input fingerprint. And after the updating of the main fingerprint data is finished, backing up the main fingerprint data into backup fingerprint data.
And 102, receiving a fingerprint data execution instruction, and loading the main fingerprint data.
Illustratively, the fingerprint data is loaded when a fingerprint data instruction is received. The loaded fingerprint data can be loaded with main fingerprint data, loaded with backup fingerprint data or randomly loaded with any one of the main fingerprint data and the backup fingerprint data, and is preferably loaded with the main fingerprint data.
And 103, if the loading of the main fingerprint data fails, loading the backup fingerprint data.
For example, when one set of fingerprint data fails to be loaded, another set of fingerprint data may be loaded to perform a corresponding function, preferably, the main fingerprint data is loaded, and if the main fingerprint data fails to be loaded, the backup fingerprint data is loaded.
According to the method for ensuring the stability of the fingerprint data provided by the embodiment of the invention, two groups of fingerprint data are prestored, wherein one group of fingerprint data is main fingerprint data, and the other group of fingerprint data is backup fingerprint data generated by backup main fingerprint data.
Example two
Fig. 2 is a flowchart of a method for ensuring stability of fingerprint data according to a second embodiment of the present invention. In this embodiment, on the basis of the above embodiment, a step of updating the main fingerprint data is added, specifically:
step 201, collecting first fingerprint data, and confirming that the first fingerprint data can be loaded and normally used.
Step 202, saving the first fingerprint data as main fingerprint data and backing up the main fingerprint data as backup fingerprint data.
And 203, calculating to obtain a hash value of the first fingerprint data, and storing the hash value of the first fingerprint data in an associated manner.
Illustratively, after the main fingerprint data is backed up as backup fingerprint data, a hash value of the first fingerprint data is calculated and stored, and when the hash value is stored, the hash value may be stored separately at the terminal, or the hash value may be stored in association, that is, the hash value and the first fingerprint data are stored in association. Preferably the association holds a hash value. In this way, each set of fingerprint data in the terminal has a corresponding hash value.
And 204, receiving a fingerprint data updating instruction, calculating a real hash value of the main fingerprint data and comparing the real hash value with the stored hash value.
Illustratively, receiving the fingerprint data updating instruction, any specified set of fingerprint data stored in the terminal may be updated, preferably the master fingerprint data. After receiving the fingerprint update instruction, calculating the true hash value of the designated updated fingerprint data and comparing the true hash value with the hash value in the previous verification loading, preferably calculating the true hash value of the main fingerprint data and comparing the true hash value with the stored hash value, if the comparison results are the same, executing step 205, and if the comparison results are different, executing step 206.
Step 205, if the true hash value is the same as the stored hash value, acquiring second fingerprint data, updating the second fingerprint data to the main fingerprint data, and backing up the updated main fingerprint data to backup fingerprint data.
For example, if the true hash value is the same as the stored hash value, indicating that the fingerprint data to be updated has not changed, at this time, second fingerprint data may be collected, where the second fingerprint data may be fingerprint data that is different from the fingerprint data to be updated, and the second fingerprint data is updated to the fingerprint data to be updated. The updating of the second fingerprint data to the fingerprint data to be updated may be replacing any fingerprint in the fingerprint data to be updated, or replacing the fingerprint data with low frequency of use in the fingerprint data to be updated, or storing the fingerprint data to be updated. And after the second fingerprint data is updated to the fingerprint data to be updated, backing up the fingerprint data to be updated to backup fingerprint data. When the second fingerprint data is collected, the second fingerprint data can be loaded, whether the second fingerprint data can be normally used or not is judged through a loading result, after the second fingerprint data can be loaded and normally used is confirmed, the second fingerprint data is updated to be the fingerprint data to be updated, the updated fingerprint data is backed up to be the backup fingerprint data, the hash value of the second fingerprint data is calculated, and the hash value of the second fingerprint is stored. Preferably, second fingerprint data is collected, it is confirmed that the second fingerprint data can be loaded and normally used, the second fingerprint data is updated to be main fingerprint data, the updated main fingerprint data is backed up to be backup fingerprint data, a hash value of the second fingerprint data is obtained through calculation, and the second fingerprint data is stored in a correlated manner. And if the collected fingerprint data cannot be loaded, deleting the fingerprint data and prompting the user to re-enter. The fingerprint data after each update can be backed up as backup fingerprint data, and can replace the original backup fingerprint data or form new backup fingerprint data. Preferably, new backup fingerprint data is formed, so that the new backup fingerprint data is backed up after each update, so that at least two groups of fingerprint data exist in the terminal.
And step 206, if the real hash value is different from the stored hash value, judging whether the main fingerprint data can be loaded.
For example, if the real hash value is different from the stored hash value, indicating that the fingerprint data to be updated has changed, it needs to determine whether the fingerprint data to be updated can be loaded, preferably, the data to be updated is the main fingerprint data, and determine whether the main fingerprint data can be loaded, if so, step 207 is executed, and if not, step 209 is executed.
And step 207, if the main fingerprint data can be loaded, replacing the corresponding stored hash value with the real hash value, and backing up the main fingerprint data into backup fingerprint data.
For example, if the fingerprint data to be updated can be loaded, indicating that the fingerprint data can be used, the true hash value of the fingerprint data to be updated calculated in step 204 is replaced with the corresponding stored hash value, and the fingerprint data to be updated is backed up as the backup fingerprint data. Preferably, the fingerprint data to be updated is main fingerprint data, if the main fingerprint data can be loaded, the real hash value is substituted for the corresponding stored hash value, and the main fingerprint data is backed up as backup fingerprint data. The backup fingerprint data can replace the original fingerprint data and can also form new backup fingerprint data.
And 208, collecting second fingerprint data, updating the second fingerprint data into the main fingerprint data, and backing up the updated main fingerprint data into backup fingerprint data.
For example, when the second fingerprint data is collected, the second fingerprint data may be loaded, whether the second fingerprint data can be normally used is judged according to the loading result, after it is confirmed that the second fingerprint data can be loaded and normally used, the second fingerprint data is updated to be the fingerprint data to be updated, and the updated fingerprint data is backed up to be the backup fingerprint data. Preferably, second fingerprint data is collected, it is confirmed that the second fingerprint data can be loaded and normally used, the second fingerprint data is updated to be main fingerprint data, and the updated main fingerprint data is backed up to be backup fingerprint data. And if the collected fingerprint data cannot be loaded, deleting the fingerprint data and prompting the user to re-enter.
And 209, if the main fingerprint data cannot be loaded, deleting all fingerprint data and prompting the user to re-enter the fingerprint.
Illustratively, if the fingerprint data to be updated cannot be loaded, indicating that the fingerprint data cannot be used, the whole fingerprint data is deleted, and the user is prompted to re-enter the fingerprint. Preferably, if the main fingerprint data cannot be loaded, all fingerprint data are deleted and the user is prompted to re-enter the fingerprint. The user can be prompted by jumping out of a prompt box on a terminal screen to prompt the user to re-enter the fingerprint.
Step 210, receiving a fingerprint data execution instruction, and loading the main fingerprint data.
And step 211, if the loading of the main fingerprint data fails, loading the backup fingerprint data.
For example, there are at least two sets of fingerprint data in the terminal, and when one set fails to load, the second set of fingerprint data can be loaded, and if there are more than two sets of fingerprint data, the rest of fingerprint data can still be loaded when the second set of fingerprint data fails to load.
In the method for ensuring stability of fingerprint data provided in the second embodiment of the present invention, when the main fingerprint data is successfully loaded and used through verification, the hash value of the main fingerprint data is calculated and stored, when a fingerprint data update instruction is received, the hash value of the main fingerprint data is calculated and compared with the stored hash value, and if the hash value of the main fingerprint data is the same as the stored hash value, the main fingerprint data is updated, and the updated main fingerprint data is backed up. The main fingerprint data can be backed up after being updated every time, if the main fingerprint data fails to be loaded, one group of backup fingerprint data can be loaded, and if one group of backup fingerprint data fails to be loaded, the other group of backup fingerprint data can be loaded. Therefore, the user can be ensured to normally use only the fingerprint data, and the stability of the fingerprint data is provided.
