In the technical aspect, by means of the bottom functions of the library of the libibileless and the iTunes, the device is subjected to two complete erasure operations so as to ensure that the data of a user cannot be recovered; firstly, we use the corresponding function to carry out the first complete erasing to the equipment, then wait for the equipment to be reconnected to the software, then carry out the activating operation to the equipment, then use the authorization technology, install the mobile phone terminal erasing APP and directly open, default to open the erasing operation, once the mobile phone erasing terminal APP is operated to be completed (the operation can carry out the comprehensive overwriting to the hard disk of the equipment so as to ensure that the data can not be recovered), we connect the hourglass checking machine client again, and carry out the operation of clearing all the data again (the second complete erasing), through a plurality of complete erasures, we can ensure that the data of the user can not be recovered, thereby achieving the operation effect of data clearing.

Example 2

Referring to fig. 1, a second embodiment of the present invention provides a method for clearing data of a mobile device, including the following steps:

All data are cleared for the equipment: the mobile phone equipment is connected to the computer by using a data line, the software can automatically search the equipment and connect the equipment, and the equipment pops up a window needing to be trusted or unlocked during connection, and the step is that a user manually operates to trust or unlock, so that the equipment can be normally managed after the user finishes the operation; at this time, the state of the display device on the software interface is: to be erased;

the first data clearing is carried out on the equipment, the step is to call a system level API inside the equipment, and the effect is as follows: setting-general-transmitting or restoring mobile phone-erasing all contents and the effect when setting clicking are the same, one key is used for carrying out operations of restoring factory settings and erasing all contents on equipment, the equipment can instantly enter an erasing mode of a black screen during operation to start data erasing on the equipment, at the moment, the equipment is not required to be subjected to any operation, automatic restarting is carried out after automatic operation of the equipment is waited, the first data erasing is completed after the system is restarted, and at the moment, the state of the equipment is displayed on a software interface: the first cleaning is successful;

waiting for the device to restart and then connecting: because the first data clearing requires restarting the device, the software stands by at this time, and waits for the data clearing completion device to be automatically reconnected to the software, and at this time, manual operation by a user may be required for unlocking; at this time, the state of the display device on the software interface is: waiting for reconnection;

activating the device: because the device is reset to an unactivated mode after the first data clearing, the next operation can be performed after the device is activated, the hardware identification code of the device is required to be collected for the activating operation, the hardware identification code is arranged into an XML format file with a standard format, the XML format file is sent to an activating server (https:// albert. App. Com/device activation) of the mobile phone, the device is required to be connected with a network, the activating server waits for data verification, and the mobile phone server returns information of successful activation of the device when the data verification passes; at this time, the state of the display device on the software interface is: the device is being activated;

installing an IOS erasure APP: in order to remove the data and ensure the function design which cannot be recovered, the method needs to be matched with an iOS APP for operation, the APP is built in software by default and can be directly installed when needed, and downloading from a server is not needed; the installation is to call an internal API of the equipment, the iOS APP is required to be uploaded to a file system in the equipment, and the corresponding installation API is called for one-key installation, and the API returns information of successful installation; at this time, the state of the display device on the software interface is: the erasure APP is being installed;

starting erasing at the mobile phone end: after the APP is successfully installed, the APP is manually clicked and opened by a user, and the APP automatically starts the erasing operation by default after opening, so that the APP generates coverage data until the equipment memory is fully occupied (the time consumption can be different according to the size of the equipment memory), and the predicted remaining time is displayed on an interface; at this time, the state of the display device on the software interface is: the mobile phone terminal is erased, at the moment, the equipment can be disconnected, and other equipment is operated;

after the mobile phone end is erased, the hourglass inspection machine is connected: after the mobile phone end is erased, the APP interface prompts the erasure completion, and the mobile phone end is connected with a computer for the next operation; at this time, the device is reconnected to the computer; at this time, the state of the display device on the software interface is: the mobile phone end is erased;

and cleaning all materials of the equipment again: in order to ensure the thoroughly degree of the data cleaning after the erasing completion degree, the equipment is cleaned again, and the process is the same as the second step;

and (3) completion: after the operation is finished, the equipment is erased, the equipment is marked, and the interface shows that the current equipment is erased.

In this embodiment, it is preferable to further include performing encryption processing on all the data to ensure that even if the data is recovered, it cannot be read; the method for encrypting all data comprises the steps of using advanced encryption standard AES, triple DES and RSA encryption algorithm;

the advanced encryption standard AES is a trusted standard algorithm used by the united states government and other organizations, 128 bit format is already very secure, but AES will also use 192 bit and 256 bit keys to achieve very demanding encryption purposes, well recognized as sufficient to cope with all attacks except brute force attacks; AES will ultimately be the preferred standard for private sector encryption of data as perceived by many internet security professionals;

triple DES is the successor of the original Data Encryption Standard (DES) algorithm created to cope with hackers attempting to break DES; applying a three-time DES algorithm to each data block, typically used to encrypt UNIX passwords and ATM PINs;

RSA is a public key encryption asymmetric algorithm, is a standard for encrypting information transmitted by a network, has strong and reliable encryption function, can generate a large number of messy codes, and is frustrated by potential hackers, because cracking a system can cause the hackers to consume a large amount of time and energy, and have to be abandoned;

when the data encryption processing is implemented, the user input UserName can be used for requesting the API of the server to acquire the key of the data encryption processing through the Http protocol, and then the UserPWD of the user and the key are combined to form a new key.

In this embodiment, preferably, the method further includes anonymizing processing technology, in which personal information and identification information are replaced by random characters or deleted, so as to protect privacy and security of users; anonymizing processing techniques include data desensitization; summarizing data; randomizing data; data generalization; data disturbance; exchanging data; sampling data; encrypting data; differential privacy;

data desensitization: the sensitive data in the personal information is replaced or encrypted, such as the mobile phone number and the identity card number are replaced by specific symbols or numbers;

data generalization: summarizing or blurring specific data in the personal information, such as summarizing and counting age ranges and income ranges;

randomizing data: randomizing specific data in the personal information, such as randomizing address and birthday data;

data generalization: replacing a particular age value with an age group, e.g., generalizing an individual aged 30 years to an age group aged 30-40 years;

data perturbation: adding random perturbations to the numerical attributes, e.g., adding a random offset to payroll values in the raw data;

and (3) data exchange: exchanging attribute values of different individuals, for example, exchanging birth dates of two different individuals in the original dataset;

sampling data: selecting a portion of the samples from the original dataset, e.g., from a dataset containing 1000 individuals, randomly selecting 100 individuals for analysis and sharing;

data encryption: encrypting the data, only authorized users can decrypt and access the original data, e.g., encrypting the entire data set using a symmetric encryption algorithm, and decrypting the data using a key;

differential privacy: privacy is protected by adding noise to the data, for example, by adding some random noise to each data point when publishing statistics, so that the individual contributions are hardly distinguishable.

In this embodiment, preferably, a file shredding technology is used to perform file-level deletion and bottom-level deletion on the sensitive file, so as to ensure that the data cannot be recovered; file shredding techniques include file-level deletion; deleting the bottom layer level; covering data; performing full-disk erasing;

file-level deletion: deleting the file name and the extension thereof or setting the file content to be zero to make the file become an invalid file; thus, the file is completely deleted and cannot be restored;

bottom level delete: the sector where the file is located is marked as being capable of being covered, so that the file is thoroughly deleted; bottom level deletion is typically more thorough than file level deletion, because even if a file is deleted, the sector in which it resides may still retain some information;

data coverage: the original data is covered by repeatedly writing random data into the storage position of the file; the data coverage can effectively prevent recovery, because the original data becomes unrecognizable due to the writing of random data;

full disk erase: all data of the whole hard disk are deleted, so that the whole hard disk becomes a brand new unallocated space, and all data can not be recovered by whole disk erasure.

Through the combined use of the technical means, the data clearing effect can be fully ensured, and the safety, the completeness and the reliability of the data of the user are ensured.

While embodiments of the present invention have been shown and described in detail with reference to the foregoing detailed description, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
