The invention relates to a mobile device with functions of data backup and data recovery. A backup data decrypting unit generates a fusion secret key according to a main secret key input by a user, an encrypted public key and an encrypted private key in a backup data package are decrypted, the decrypted private key is used for decrypting an encrypted Hash value in the backup data package to obtain a first Hash value. A Hash value calculation unit calculates out a second Hash value of encrypted user data, the public key and the private key in the backup data package. When a Hash value comparison unit determines that the first Hash value is equal to the second Hash value, the backup data decrypting unit decrypts the user data with the obtained private key after decryption. A processing unit is used for executing the corresponding mobile device updating program. The invention further provides a method for performing data backup and data recovery on the mobile device. By means of the mobile device with the functions of data backup and data recovery and the method for performing data backup and data recovery on the mobile device, the main secret key input by the user is used for generating the fusion secret key to decrypt the public key, the private key and the user data in the backup data package in order to update the system. The safety problem in storage of backup files in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of backup, in particular to a mobile device with data backup and data recovery functions and a data backup and data recovery method. Background technique [0002] With the development of mobile technology, portable mobile devices, such as smart phones, tablet computers, etc., have an important role in the system files related to the operation and security of mobile devices. Therefore, the backup, restoreability and security of system files are more more and more important. In the prior art, a mobile device usually has a corresponding removable storage medium, such as an optical disc, for storing backup files of system files. However, the data loss and data security of the mobile storage medium make certain risks exist when the mobile device installs the backup file. Contents of the invention [0003] In view of this, it is necessary to provide a mobile device and method with data backup and data recovery...
