The third embodiment:
the present invention will now be further explained with reference to specific application scenarios.
According to the embodiment, the security and convenience of fingerprint identification are utilized, so that the PC software controls the mobile phone resources in a secure environment, and the backup, deletion and other operations are completed. The invention does not increase the basis of hardware cost, can ensure that a user operates the mobile phone through the PC under the environment of enough safety, and has the characteristics of safety and convenience; the fingerprint identification is a trigger condition for switching the USB mode of the mobile phone, and the condition that the PC must be under the permission of a user when the PC wants to acquire the mobile phone data and the control right through the USB is guaranteed. According to the embodiment, an uncommon finger is input as a special fingerprint template, after the fingerprint is identified, the mobile phone is automatically switched to the USB controllable mode, data can be copied to the computer side through PC software, and personal information in the mobile phone is deleted (factory settings are restored).
The embodiment mainly comprises two steps of fingerprint input/identification and mobile phone mode conversion. The working principle is as follows:
first step fingerprint input/identification: the fingerprint of a special finger is recorded into the mobile phone, and an uncommon finger is generally selected. The fingerprint can be used for switching the subsequent mobile phone modes without participating in conventional operations such as screen unlocking, payment and the like. When the fingerprint is identified to be the special finger, the mobile phone enters mode switching. In order to ensure that the information of the mobile phone is not leaked, a special encryption mode is required in the step.
Second step, switching mobile phone modes: when the special fingerprint is detected, the mobile phone can be automatically switched to a USB communication mode. The mode can be realized in a plurality of ways, for example, a, the mobile phone backs up important information resources (including an address book, a photo, common software and the like) of the mobile phone, and the USB port is mapped into a USB disk mode, so that a user can copy the USB disk mode conveniently; b. the mobile phone maps the USB into a debugging mode, more resource control authority is given to the PC side software, the PC side software reads/deletes corresponding data from the mobile phone memory, and various other operations (such as sending short messages, making calls, sharing data traffic and the like) can be carried out on the mobile phone. The mobile phone is restarted, waits overtime or recovers to a normal mode after the USB is disconnected, related functions of the USB are closed, and the information safety of a user is protected.
Because the finger fingerprint of each person has uniqueness, only one fingerprint of a user has the authority, so that the safety of user information is ensured by the input and identification of special fingerprints; because the fingerprint can realize the switching of the mobile phone mode by only pressing once, the normal communication between the USB port and the PC side is ensured, and the method has good convenience. When a user needs to connect a mobile phone at a PC side, the USB automatically completes switching by only lightly performing fingerprint identification once, and related resource information is also backed up or can be accessed by the PC; and at other times, the mobile phone is in a state that the PC cannot be connected, so that illegal invasion to the mobile phone of the user is prevented. Therefore, the convenience of operation and the safety of user information are ensured.
In practical application, the entry and identification of special fingerprints can cause the leakage of mobile phone information if being cracked, so that a corresponding operation must be added into a specific encryption operation. It is not the same as the common way of fingerprint processing. The fingerprint is identified not for normal operations such as screen unlocking and payment, but for switching the mobile phone to the USB communication mode, so that the PC software can acquire the data resources in the mobile phone and the operation right thereof. The fingerprint is preferably selected to be less commonly used, such as the small finger, to prevent false triggering.
During the production of mobile phones, a pair of keys (private key and public key) is generated, wherein the private key is used for encryption and the public key is used for decryption. Storing a private key in a mobile phone Trustzone area (a safe area cannot be accessed by common applications and cannot be erased after factory settings are restored; for example, RPMB of a high-pass platform, the modified Memory Block); the public key is stored in the fingerprint unlocking application. Fingerprint data is transmitted between the Trustzone area and an application arranged in a Non-Trustzone Non-safety area, data leakage or fake data can exist, and therefore encryption transmission is required.
As shown in fig. 3, the fingerprint recording is divided into two blocks: fingerprint recording, template storage and fingerprint id generation and transmission are carried out in the Trustzone area; and acquiring and storing the fingerprint id in the Non-Trustzone area. Generally, all operations performed in the Trustzone area are safe and reliable. However, if the special fingerprint id leaks in the Non-Trustzone area, the special fingerprint id may be counterfeited by others, so that the mobile phone mistakenly opens the operation right to the PC side, and information and resources are leaked. The fingerprint and the time stamp are encrypted with a private key in step 205, and the encrypted information is decrypted with a public key in steps 206, 207, 208, and subjected to judgment processing. The time stamp is added to prevent others from duplicating the new fingerprint id information with the old fingerprint id encryption information. If the application judges that the time stamp exceeds a certain range, the data is considered to be counterfeit data and is discarded.
As shown in fig. 4, fingerprint identification is consistent with fingerprint entry. Encrypting the id and the timestamp when the fingerprint id is transmitted in the Trustzone area; and decrypting the encrypted information in the application test, judging the fingerprint id and the timestamp, and processing according to the judgment condition.
In practical application, if a special fingerprint is deleted, the deletion can be consistent with the deletion of a common fingerprint because the leakage risk of information is not involved.
Therefore, the safety of user information and data can be ensured by the operation, and the operation is convenient. With slight modifications in the code.
As shown in fig. 5, the method for switching modes of a mobile phone provided in this embodiment includes:
s501: in the event of a device failure, a special fingerprint is identified.
This step can be implemented by the method shown in fig. 4 to identify a specific fingerprint.
S502: and the terminal is switched to a USB debugging mode.
S503-S507: and the mobile phone processes the user data.
The embodiment is the mode switching of the mobile phone after fingerprint identification, which comprises data backup, USB interface conversion and corresponding operation in cooperation with a PC side instruction. The main purpose is to make PC software extract relevant data from the mobile phone through USB and perform certain operation on the mobile phone. A, the mobile phone backs up important information resources (including an address book, a photo, common software and the like), and a USB port is mapped into a USB disk mode, so that a user can copy the information conveniently; b. the mobile phone maps the USB into a debugging mode, more resource control authority is given to the PC side software, the PC side software reads corresponding data from the internal memory of the mobile phone, and the PC is operated to carry out various other operations (such as sending short messages, making calls, deleting data, recovering factory settings and the like) on the mobile phone. The mobile phone is restarted, waits overtime or recovers to a normal mode after the USB is pulled out, related functions of the USB are closed, and the information safety of a user is protected. Fig. 5 shows an implementation of the scheme b in detail.
In the embodiment, different working modes of the mobile phone USB are triggered by fingerprint identification, so that the PC is ensured to acquire the control right of the mobile phone through the USB within the range allowed by a user. By the mode, the safety of user operation is ensured, and the user is not required to set complicated USB permission. Even if the screen is damaged, the mobile phone can still be used as a data card, data leakage is not worried about, and the mobile phone has the characteristics of safety and convenience.
