Detailed ways

The technical solution in the embodiment of the present invention will be clarified in the following with reference to the accompanying drawings in the embodiments of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS It is apparent that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The method for selecting a roaming network according to an embodiment of the present invention is described. FIG. 1 is a flowchart of a data backup method according to an embodiment of the present invention. As shown in FIG. 1, this embodiment includes:

101. Obtain backup data.

The backup data is data selected by the user and needs to be backed up, and may be various data on the smart terminal; for example, may include contact information, short message, call record, saved WiFi network information, installed application, application Data, pictures, videos, music, operating system settings, alarm information, memo information, and more. Users can choose the data they need to back up according to their needs.

102. Acquire verification fingerprint information used by the user for verification.

After the user selects the backup data, the prompt information for the user to input the verification fingerprint is displayed on the display screen. After the user sees the prompt, the finger corresponding to the verification fingerprint can be placed at the fingerprint identifier position, and the fingerprint identifier is used to collect the fingerprint. Thereby obtaining verification fingerprint information. The verification fingerprint information may be a character string obtained by a preset algorithm.

The fingerprint identifier can be self-contained by the smart terminal, and the fingerprint can be collected by an external fingerprint identifier.

103. Encrypt the verification fingerprint information and the backup data by using encrypted fingerprint information.

When the backup data needs to be encrypted, the prompt information for allowing the user to input the encrypted fingerprint may be displayed on the display screen. After the user sees the prompt, the finger corresponding to the encrypted fingerprint may be placed at the fingerprint recognizer position, and the fingerprint recognizer Collect fingerprints to obtain encrypted fingerprint information.

After the encrypted fingerprint information is obtained, the encrypted fingerprint information may be calculated into a corresponding character string according to a preset algorithm, and then the verification fingerprint information and the backup data are encrypted by the string.

The preset encryption algorithm may be a symmetric encryption algorithm or an asymmetric encryption algorithm. For example, symmetric encryption means that encryption and decryption use the same key. The encryption technology commonly called "Session Key" is widely used today. For example, the DES encryption standard adopted by the US government is a typical "symmetric". "Encryption method, its Session Key length is 56bits. Asymmetric encryption is not the same key used for encryption and decryption. There are usually two keys, called "public key" and "private key". They must be paired together. Otherwise, the encrypted file cannot be opened. The "public key" here refers to the publicity, and the "private key" cannot, and can only be known by the holder. Its superiority Here, because the symmetric encryption method is difficult to tell the other party if the encrypted file is transmitted over the network, it may not be eavesdropped by any means. The non-symmetric encryption method has two keys, and the "public key" is publicly available, so it is not afraid of others knowing that the recipient can decrypt it with his own private key, which is good. The transmission security of the key is avoided.

Specifically, a DES algorithm (Data Encryption Standard) can be used (a symmetric algorithm, a data encryption standard, which is fast, and is suitable for encrypting a large amount of data); or a 3DES (Triple DES) algorithm (a symmetric algorithm based on DES, a pair of symmetry algorithms) Data is encrypted with three different keys for three times, with higher strength; or RC2 and RC4 algorithms (symmetric algorithm, encrypting large amounts of data with variable length keys, faster than DES); or IDEA (International Data Encryption Algorithm) Algorithm (international data encryption algorithm, using 128-bit key to provide very strong security); RSA algorithm (invented by RSA, is a public key algorithm that supports variable length keys, the length of the file block that needs to be encrypted is also Variable, asymmetric algorithm); or hash algorithm (Hash) algorithm to verify fingerprint information and backup data for encryption.

The embodiment of the present invention does not limit a specific encryption algorithm, and any encryption algorithm does not affect the implementation of the embodiment of the present invention. However, in practical applications, it is recommended to use an encryption algorithm that does not require very high system resources, thereby increasing the encryption speed.

In order to improve security, the user may be prompted on the display screen to input another fingerprint different from the verification fingerprint as the encrypted fingerprint. In one embodiment, although the user is prompted to input another fingerprint different from the verification fingerprint as the encrypted fingerprint, even if the user uses the same fingerprint as the verification fingerprint as the encrypted fingerprint, the system continues to use the fingerprint for encryption, thereby reducing the user. In another implementation manner, if the user inputs the same fingerprint as the verification fingerprint as the encrypted fingerprint, the system may prompt the user to input another fingerprint, so that the backup data is not encrypted using the same fingerprint as the verification fingerprint. To further improve security.

104. Save the encrypted backup file, where the backup file includes the verification fingerprint information and the backup data.

The backup file can be saved on the smartphone, and then the backup file can be transferred through the communication between the mobile phones; or the backup file can be saved on the external storage disk (such as USB flash drive, mobile hard disk, etc.), through the movement of the storage disk The backup data is transferred; or the backup file can be saved in the cloud, and the backup file can be obtained anywhere that has an Internet connection.

It can be seen that, in the embodiment of the present invention, the verification fingerprint information and the backup data are encrypted by the encrypted fingerprint information when the data is backed up, so that the encrypted backup data needs to pass the verification finger when decrypting. The double verification of the pattern and the encrypted fingerprint can protect the user's backup data very safely. At the same time, since the backup data is backed up by using the fingerprint information, the user does not need to remember any password, thereby being convenient for the user to use and safely protect. User data.

FIG. 2 is a flowchart of a method for data backup provided by another embodiment of the present invention, including:

201. Obtain backup data.

202. Acquire verification fingerprint information used by the user for verification.

203. Encrypt the verification fingerprint information and the backup data by using encrypted fingerprint information.

204. Save the encrypted backup file, where the backup file includes the verification fingerprint information and the backup data.

205. Receive a backup file acquisition request input by a user, where the obtaining request includes decrypting fingerprint information.

When the user switches to the new smart terminal, after obtaining the backup file, the file can be decrypted, thereby obtaining backup data, such as contact information, short message, call record, saved WiFi network information, installed application, The application's data, pictures, videos, music, operating system settings, alarm information, memo information, etc. are transferred to the new smart terminal without much manual setup.

Specifically, when the user needs to decrypt the backup file, the prompt information for allowing the user to input the decrypted fingerprint may be displayed on the display screen. After the user sees the prompt, the finger corresponding to the decrypted fingerprint may be placed at the fingerprint identifier position, and the fingerprint is The recognizer collects fingerprints to obtain decrypted fingerprint information. Wherein, the user may be further prompted to decrypt the fingerprint as a fingerprint used when encrypting the backup data, so that the user can determine which finger is used for decryption more quickly.

206. Determine whether the decrypted fingerprint information is the same as the encrypted fingerprint information; if the decrypted fingerprint information and the encrypted fingerprint information are the same, go to step 207; if the decrypted fingerprint information and the encrypted fingerprint information are different, Proceed to step 208.

Specifically, the decrypted fingerprint information may be converted into a character string by using the same algorithm as that used in encryption, and then the string is used as a decrypted password to decode the backup file; if the string is the same as the encrypted string, the decryption can be successfully performed. Conversely, if the string is not the same as the encrypted string, the decryption cannot be successful.

207. Decrypt the backup file.

In an embodiment of the present invention, the verification of the fingerprint is performed while the backup file is being decoded. In this case, the process of decrypting the backup file may include:

Decrypting the backup file to obtain the verification fingerprint information; acquiring the fingerprint to be verified input by the user; if the fingerprint to be verified is the same as the verification fingerprint, decrypting the backup data; if the fingerprint to be verified and the verification fingerprint Not the same, the backup data is not decrypted.

In another embodiment of the present invention, after the decryption file is decrypted, the verification of the verification fingerprint is performed. The method provided by the embodiment of the present invention may further include: acquiring a fingerprint to be verified input by the user; And the same as the verification fingerprint, outputting the backup data obtained by decrypting the backup file; if the fingerprint to be verified is different from the verification fingerprint, deleting the backup data and the verification fingerprint obtained by decrypting the backup file.

Specifically, when the verification fingerprint needs to be verified, the user may be prompted to verify the verification fingerprint on the display screen. After the user puts the verification fingerprint on the fingerprint identifier, the fingerprint to be verified can be collected; the same algorithm as the verification fingerprint information is used to calculate the verification fingerprint to obtain the verification target. The specific information of the fingerprint information to be verified may be a character string, and the character string corresponding to the fingerprint to be verified is compared with the saved character string corresponding to the verification fingerprint, and the character string corresponding to the fingerprint to be verified and the saved If the verification string is the same, the verification is successful. Otherwise, if the character string corresponding to the fingerprint to be verified is different from the saved character string corresponding to the verification fingerprint, the verification is unsuccessful.

208. The backup file is not decrypted.

It can be seen that, in the embodiment of the present invention, the verification fingerprint information and the backup data are encrypted by the encrypted fingerprint information when the data is backed up, so that the encrypted backup data needs to be verified by the double verification of the verification fingerprint and the encrypted fingerprint when decrypting, which can be very safe. The user's backup data is protected, and since the backup data is backed up using the fingerprint information, the user does not need to remember any password, thereby being convenient for the user to use and securely protecting the user data.

The obtaining unit 301 is configured to acquire backup data, and obtain verification fingerprint information used by the user for verification.

The encryption unit 302 is configured to encrypt the verification fingerprint information and the backup data by using the encrypted fingerprint information.

After obtaining the encrypted fingerprint information, the encrypted fingerprint information may be calculated according to a preset algorithm. It is counted as the corresponding string, and then the verification fingerprint information and the backup data are encrypted by the string.

The preset encryption algorithm may be a symmetric encryption algorithm or an asymmetric encryption algorithm. For example, symmetric encryption means that encryption and decryption use the same key. The encryption technology commonly called "Session Key" is widely used today. For example, the DES encryption standard adopted by the US government is a typical "symmetric". "Encryption method, its Session Key length is 56bits. Asymmetric encryption is not the same key used for encryption and decryption. There are usually two keys, called "public key" and "private key". They must be paired together. Otherwise, the encrypted file cannot be opened. The "public key" here refers to the publicity, and the "private key" cannot, and can only be known by the holder. Its superiority is here, because the symmetric encryption method is difficult to tell the other party if the encrypted file is transmitted over the network, no matter what method is used, it may be hacked. The non-symmetric encryption method has two keys, and the "public key" is publicly available, so it is not afraid of others knowing that the recipient can decrypt it with his own private key, which is good. The transmission security of the key is avoided.

Specifically, the decrypted fingerprint information can be converted into a character string by using the same algorithm as when encrypting, The string is then used as a decryption password to decode the backup file; if the string is the same as the encrypted string, the decryption can be successful. Conversely, if the string is not the same as the encrypted string, the decryption cannot be successful.
