[0069] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0070] With the development of science and technology, network information technology has been advancing by leaps and bounds, greatly facilitating communication between people. The Internet involves various information such as images, sounds, and texts. People can easily obtain other people's information with the help of computers and the Internet, which poses a great hidden danger to other people's personal privacy. Therefore, the protection of personal information, such as mobile phone numbers, ID card numbers and other data, has become a top priority. Most mobile phone numbers are now encrypted using AES or MD5 encryption. The first two encryptions are relatively cumbersome, especially MD5 encryption, which is not very convenient for subsequent mobile phone numbers. Therefore, a core invention of an embodiment of the present invention is to construct a method for generating encrypted data, which not only ensures that the data to be encrypted does not appear in plain text, but also prevents the encryption process from taking up too much computing power.

[0071] Reference Figure 1 , shows a flowchart of a method for generating encrypted data provided in an embodiment of the present invention, which may specifically include the following steps:

[0072] Step 101, obtaining data to be encrypted and generating a public array;

[0073] Step 102, splitting the data to be encrypted according to a preset rule to generate first data to be encrypted and second data to be encrypted;

[0074] Step 103, determining third data to be encrypted corresponding to the first data to be encrypted from the public array using the first data to be encrypted;

[0075] Step 104, generating 32-bit binary data for the second data to be encrypted using the third data to be encrypted;

[0076] Step 105, replacing the first bit of the 32-bit binary data with the first data to be encrypted, and generating encrypted data; the encrypted data includes the first data to be encrypted and a 31-bit binary string.

[0077] In a specific implementation, the embodiment of the present invention can obtain the data to be encrypted, for example, obtain the user's mobile phone number or ID card number and other data, and generate a public array, refer to Figure 2 , Figure 2 It is a schematic diagram of a common array provided in an embodiment of the present invention. The common array may be composed of 10 common data and subscripts corresponding to the common data one by one. The subscripts may be integers of 0-9, and the subscripts do not appear repeatedly.

[0078] In a specific implementation, the public array in the embodiment of the present invention may be sent to a data decryption device, and the data decryption device may decrypt the encrypted data based on the public array.

[0079] After obtaining the data to be encrypted and generating a common array, the embodiment of the present invention can split the data to be encrypted according to a preset rule to generate first data to be encrypted and second data to be encrypted. For example, the data to be encrypted can be "18894554188", and then the first digit 1 of the number is removed, and the last digit 8 of the number is intercepted, which is recorded as: A, A=8, and the remaining nine digits "889455418" are recorded as: B, where A is the first data to be encrypted and B is the second data to be encrypted.

[0080] Of course, the above examples are only for illustration, and those skilled in the art may use any other rules to split the data to be encrypted, thereby generating the first data to be encrypted and the second data to be encrypted, and the embodiments of the present invention are not limited to this.

[0081] After generating the first data to be encrypted and the second data to be encrypted, the embodiment of the present invention can determine the third data to be encrypted corresponding to the first data to be encrypted from the public array through the first data to be encrypted. For example, the data to be encrypted can be "18894554188", and then the first digit 1 of the number is removed, and the last digit 8 of the number is intercepted, which is recorded as: A, A=8, and the remaining nine digits "889455418" are recorded as: B, where A is the first data to be encrypted and B is the second data to be encrypted. Figure 2 Since the first data to be encrypted is "8", in the public array, the public data corresponding to 8 is "23", so the third data to be encrypted is generated as M=23.

[0082] After determining the third data to be encrypted corresponding to the first data to be encrypted from the public array through the first data to be encrypted, the embodiment of the present invention can generate 32-bit binary data for the data to be encrypted through the third data to be encrypted. For example, the data to be encrypted can be "18894554188", and then the first digit 1 of the number is removed, and the last digit 8 of the number is intercepted, which is recorded as: A, A=8, and the remaining nine digits "889455418" are recorded as: B, where A is the first data to be encrypted and B is the second data to be encrypted. Figure 2 , since the first data to be encrypted is "8", in the public array, the public data corresponding to 8 is "23", so the third data to be encrypted is generated as M=23, C=BA=889455418-8=889455410, D=CM, D=889455410-23=889455387, and the digital data of positions 3, 6, and 9 in the public array are recorded as: X, Y, Z, X=66, Y=33, Z=52. E=DXYZ, E=889455387-66-33-52=889455236, and E is converted into a 32-bit binary number F=00110101000001000000001010000100.

[0083] Of course, the above examples are only for illustration, and those skilled in the art may use other algorithms to generate 32-bit binary data through the third-generation encrypted data, and the embodiments of the present invention are not limited to this.

[0084] In a specific implementation, the embodiment of the present invention can replace the first bit of the 32-bit binary data with the first data to be encrypted, and generate encrypted data including the first data to be encrypted and a 31-bit binary string.

[0085] For example, the data to be encrypted can be "18894554188", then remove the first digit 1 of the number, cut off the last digit 8 of the number, record it as: A, A = 8, the remaining nine digits "889455418" is recorded as: B, where A is the first data to be encrypted, and B is the second data to be encrypted. Figure 2, since the first data to be encrypted is "8", in the public array, the public data corresponding to 8 is "23", so the third data to be encrypted is M=23, C=BA=889455418-8=889455410, D=CM, D=889455410-23=889455387, and the data at positions 3, 6, and 9 in the public array are recorded as: X, Y, Z, X=66, Y=33, Z=52. E=DXYZ, E=889455387-66-33-52=889455236, change E into a 32-bit binary number F=00110101000001000000001010000100, replace the leftmost sign bit of F with A, and get the final encryption result G of 80110101000001000000001010000100, and use G as the encrypted data.

[0086] In an embodiment of the present invention, data to be encrypted is obtained and a common array is generated; the data to be encrypted is split according to a preset rule to generate first data to be encrypted and second data to be encrypted; third data to be encrypted corresponding to the first data to be encrypted is determined from the common array through the first data to be encrypted; 32-bit binary data for the second data to be encrypted is generated through the third data to be encrypted; the first bit of the 32-bit binary data is replaced by the first data to be encrypted, and encrypted data is generated; the encrypted data includes the first data to be encrypted and a 31-bit binary string, thereby improving the security of the data to be encrypted during the encryption process.

[0087] Based on the above embodiment, a variant embodiment of the above embodiment is proposed. It should be noted that in order to make the description concise, only the differences from the above embodiment are described in the variant embodiment.

[0088] In an optional embodiment of the present invention, the step of splitting the data to be encrypted according to a preset rule to generate first data to be encrypted and second data to be encrypted includes:

[0089] Determining a first target digit and a second target digit for the data to be encrypted;

[0090] Determining first target data from the data to be encrypted based on the first target digit, and extracting the first target data as first data to be encrypted;

[0091] Determining second target data from the data to be encrypted based on the second target digit;

[0092] The first target data and the second target data are deleted from the data to be encrypted to generate second data to be encrypted.

[0093] In practical applications, if the original data to be encrypted is directly encrypted and the encrypted data generated is easily reverse cracked, therefore, the embodiment of the present invention can determine the first target digit and the second target digit for the data to be encrypted; determine the first target data from the data to be encrypted based on the first target digit, and extract the first target data as the first data to be encrypted, determine the second target data from the data to be encrypted based on the second target digit, delete the first target data and the second target data from the data to be encrypted, and generate the second data to be encrypted.

[0094] For example, the data to be encrypted is "18894554188", the first target digit is determined to be "the 11th digit", and the second target digit is "the 1st digit". Based on the first target digit "the 11th digit", the first target data is determined to be "8" from "18894554188", and "8" is extracted as the first data to be encrypted. Based on the second target digit "the 1st digit", the second target data is determined to be "1" from "18894554188", and the first target data "8" and the second target data "1" are deleted from the data to be encrypted "18894554188" to generate the second data to be encrypted "889455418".

[0095] Of course, the above examples are only for illustration. When the data to be encrypted is a Chinese mobile phone number, the first target digit can be any digit except the first digit, and the embodiment of the present invention does not limit this.

[0096] Optionally, the first target data may be digital data mutually agreed upon by the data encryption party and the data decryption party. For example, if the data encryption party defines the first target data as the last digit of the data to be encrypted, then the data decryption party also considers that the first target data is defined as the last digit of the data to be encrypted. Alternatively, if the data encryption party defines the first target data as the second to last digit of the data to be encrypted, then the data decryption party also considers that the first target data is defined as the second to last digit of the data to be encrypted. The second encrypted data may be common data of multiple data to be encrypted. For example, the first digit of Chinese mobile phone numbers is always "1", so the first digit may be used as the second encrypted data.

[0097] The embodiment of the present invention determines a first target digit and a second target digit for the data to be encrypted; determines first target data from the data to be encrypted based on the first target digit, and extracts the first target data as the first data to be encrypted; determines second target data from the data to be encrypted based on the second target digit; deletes the first target data and the second target data from the data to be encrypted to generate second data to be encrypted, thereby effectively preventing the encrypted data from being reverse cracked and further improving the security of confidential data.

[0098] In an optional embodiment of the present invention, the step of generating 32-bit binary data for the second data to be encrypted by using the third data to be encrypted includes:

[0099] Generate fourth data to be encrypted based on a first preset encryption algorithm using the first data to be encrypted and the second data to be encrypted;

[0100] Generate fifth data to be encrypted based on a second preset encryption algorithm using the third data to be encrypted and the fourth data to be encrypted;

[0101] Determine digital data for the public array according to a preset rule, and determine at least one target public data from the public array based on the digital data;

[0102] Generate sixth data to be encrypted based on a third preset encryption algorithm using the fifth data to be encrypted and the target public data;

[0103] The sixth data to be encrypted is converted into 32-bit binary data.

[0104] In practical applications, single-layer encryption is easily reverse cracked. Therefore, the embodiment of the present invention can determine the third data to be encrypted and generate 32-bit binary data for the data to be encrypted through the third data to be encrypted, and then use the digital data for the public array in combination with multiple preset encryption algorithms to generate encrypted data, so as to further improve the security of the encrypted data. Specifically, the embodiment of the present invention can use the first data to be encrypted and the second data to be encrypted to generate the fourth data to be encrypted based on the first preset encryption algorithm, use the third data to be encrypted and the fourth data to be encrypted to generate the fifth data to be encrypted based on the second preset encryption algorithm, determine the digital data for the public array according to preset rules, and determine at least one target public data from the public array based on the digital data, use the fifth data to be encrypted and the target public data to generate the sixth data to be encrypted based on the third preset encryption algorithm, and convert the sixth data to be encrypted into 32-bit binary data.

[0105] For example, the data to be encrypted is "18894554188", where the first data to be encrypted A = 8, the second data to be encrypted B = 889455418, and the fourth data to be encrypted by the first preset encryption algorithm is C = BA = 889455418-8 = 889455410. Since the first data to be encrypted is "8", refer to Figure 2, in the public array, the public data corresponding to 8 is "23", so the third data to be encrypted is M=23, and the fifth data to be encrypted "889455387" is generated by the second preset encryption algorithm D=CM=889455410-23=889455387. Assuming that the preset rule is to take the digital data in the public array as 3, 6, 9", it can be determined that the target public data X=66, Y=33, Z=52, and through the third preset encryption algorithm E=DXYZ=889455387-66-33-52=889455236, the sixth data to be encrypted is generated as "889455236", and then the sixth data to be encrypted "889455236" is converted into 32-bit binary to generate 32-bit binary data F=00110101000001000000001010000100.

[0106] Of course, the above examples are only for illustration. Those skilled in the art may adopt other algorithms as the first preset encryption algorithm to generate the fourth data to be encrypted, may adopt other algorithms as the second preset encryption algorithm to generate the fifth data to be encrypted, and may adopt other algorithms as the third preset encryption algorithm to generate the sixth data to be encrypted. In addition, the preset rules for obtaining public data are not limited in the present invention. The preset rules may be the public data corresponding to any at least one digital data in the public array. The embodiments of the present invention do not impose any restrictions on this.

[0107] In an optional embodiment of the present invention, the first preset encryption algorithm has a corresponding first preset decryption algorithm, the second preset encryption algorithm has a corresponding second preset decryption algorithm, the third preset encryption algorithm has a corresponding third preset decryption algorithm, and the method further includes:

[0108] Extracting the first to-be-encrypted data and the 31-bit binary string from the encrypted data;

[0109] Generate the sixth data to be encrypted by using the 31-bit binary string; the sixth data to be encrypted is decimal data;

[0110] Generate fifth data to be encrypted based on a third preset decryption algorithm using the sixth data to be encrypted and the public data;

[0111] Determining third data to be encrypted corresponding to the first data to be encrypted from the public array using the first data to be encrypted;

[0112] Generate fourth data to be encrypted based on the second preset decryption algorithm using the third data to be encrypted and the fifth data to be encrypted;

[0113] Generate second data to be encrypted based on the first preset decryption algorithm using the fourth data to be encrypted and the first data to be encrypted;

[0114] The first data to be encrypted, the second target data and the second data to be encrypted are concatenated to generate the data to be encrypted.

[0115] In practical applications, the encrypted data needs to be decrypted during use. For example, a telephone number is encrypted for data transmission. After the recipient receives the encrypted data, the encrypted data (ciphertext) needs to be decrypted and restored to the original data to be encrypted (plaintext). Therefore, an embodiment of the present invention can extract the first data to be encrypted and a 31-bit binary string from the encrypted data, and generate the sixth data to be encrypted through the 31-bit binary string; the sixth data to be encrypted is decimal data, and the sixth data to be encrypted and public data are used to generate the fifth data to be encrypted based on the third preset decryption algorithm. The third data to be encrypted corresponding to the first data to be encrypted is determined from the public array through the first data to be encrypted, and the third data to be encrypted and the fifth data to be encrypted are used to generate the fourth data to be encrypted based on the second preset decryption algorithm. The fourth data to be encrypted and the first data to be encrypted are used to generate the second data to be encrypted based on the first preset decryption algorithm. The first data to be encrypted, the second target data, and the second data to be encrypted are concatenated to generate the data to be encrypted.

[0116] For example, the data to be encrypted is "18894554188", the first target digit is determined to be "the 11th digit", the second target digit is determined to be "the 1st digit", the first target data is determined to be "8" from "18894554188" based on the first target digit "the 11th digit", and "8" is extracted as the first data to be encrypted, and the second target data is determined to be "1" from "18894554188" based on the second target digit "the 1st digit", and the first target data "8" and the second target data "1" are deleted from the data to be encrypted "18894554188" to generate the second data to be encrypted "889455418", since the first data to be encrypted A = 8, the second data to be encrypted B = 889455418, the fourth data to be encrypted through the first preset encryption algorithm is C = BA = 889455418-8 = 889455410, since the first data to be encrypted is "8", refer to Figure 2In the public array, the public data corresponding to 8 is "23", so the third data to be encrypted is M=23. The fifth data to be encrypted "889455387" is generated by the second preset encryption algorithm D=CM=889455410-23=889455387. Assuming that the preset rule is to take the public data with digital data of 3, 6, and 9 in the public array", the target public data X=66, the target public data Y=33, and the target public data Z=52 can be determined. The sixth data to be encrypted is "889455236" generated by the third preset encryption algorithm E=DXYZ=889455387-66-33-52=889455236. Then, the sixth data to be encrypted "889455236" is converted into 32-bit binary to generate 32-bit binary data F=00110101000001 000000001010000100, replace the leftmost sign bit of F with the first data to be encrypted A, and get the final encryption result G is 80110101000001000000001010000100, and use G as the encrypted data. Since the encrypted data is "800110101000001000000001010000100", the first data to be encrypted "8" and the 31-bit binary string "00110101 000001000000001010000100", then "0011010100000100000001010000100" is converted into decimal to generate the sixth encrypted data E=889455236. It is known that the public data X=66, Y=33, Z=52. The sixth encrypted data E=889455236 is used based on the third preset decryption algorithm D=E+X+Y+Z=889455236+66+33+52=889 455387, and obtain the fifth data to be encrypted D=889455387. The first data to be encrypted A=8 is known, and the corresponding public data in the public array is "23", so the third data to be encrypted M=23. The third data to be encrypted M=23 and the fifth data to be encrypted D=889455387 are used to generate the fourth data to be encrypted C=D+M=889455387+23=889455410 based on the second preset decryption algorithm. Then, the fourth data to be encrypted C=889455410 and the first data to be encrypted A=8 are used to generate the second data to be encrypted B=889455418 based on the first preset decryption algorithm B=C+A=889455418. The second target data "1", the first data to be encrypted "8" and the second data to be encrypted "889455418" are concatenated to obtain "18894554188" to generate encrypted data.

[0117] In practical applications, the concatenation rule for concatenating the second target data, the first data to be encrypted and the second data to be encrypted to generate encrypted data may be based on the first target digit and the second target digit corresponding to the first data to be encrypted and the second target data.

[0118] In an optional embodiment of the present invention, when the data to be encrypted is a mobile phone number, the second target data is the first digit of the data to be encrypted, and the first data to be encrypted is any digit of data except the first digit.

[0119] Optionally, an embodiment of the present invention can first determine whether the data to be encrypted is a mobile phone number. For example, it can determine whether the data to be encrypted is an 11-digit pure number starting with 13, 14, 15, 16, 17, 18, or 19; if so, it is determined that the data to be encrypted is a mobile phone number, and when it is determined that the data to be encrypted is a mobile phone number, the second target data is the first digit of the data to be encrypted, and the first data to be encrypted is any digit of data except the first digit.

[0120] For example: the data to be encrypted is "18894554188" and meets the conditions of "11 pure digits" and "starting with 18". In this case, the data to be encrypted is a mobile phone number, the second target data is the first digit "1" of "18894554188", and the first data to be encrypted is the 11th digit "8" except the first digit.

[0121] The above examples are only for illustration, and those skilled in the art may determine whether it is a mobile phone number in other ways, and the embodiments of the present invention are not limited to this.

[0122] In order to enable those skilled in the art to better understand the embodiments of the present invention, a complete example is used below to illustrate the embodiments of the present invention.

[0123] refer to Figure 3 , Figure 3 It is a step flow chart of a data encryption method provided in an embodiment of the present invention.

[0124] Step 1: Get the mobile phone number 18894554188 and encrypt and decrypt the public array reference Figure 2 .

[0125] Step 2: Determine whether the mobile phone number meets the encryption conditions: 11 pure digits, Chinese mobile phone numbers starting with 13, 14, 15, 16, 17, 18, 19. The mobile phone number starting with 18 meets the conditions.

[0126] Step 3: Encryption, remove the first digit 1 of the mobile phone number, and take the last digit 8 of the mobile phone number, recorded as: A, A=8, and the remaining nine digits are recorded as: B, B=889455418, C=BA, C=889455418-8=889455410. According to A, get M=23, D=CM, D=889455410-23=889455387 from the public array, and take the data at the subscripts 3, 6, and 9 in the public array as: X, Y, Z, X=66, Y=33, Z=52. E=DXYZ,E=889455387-66-33-52=889455236,Change E into a 32-bit binary number F,F=00110101000001000000001010000100,Replace the leftmost sign bit of F with A,The final encryption result G is: 80110101000001000000001010000100

[0127] refer to Figure 4 , Figure 4 It is a step flow chart of a data decryption method provided in an embodiment of the present invention.

[0128] Step 4: Decryption. The result of encryption is: 80110101000001000000001010000100. Split the encrypted data, take out the leftmost 8, A=8, and convert the remaining 31 binary digits into decimal E: 889455236. In the public array, take the data at positions 3, 6, and 9 and record them as: X, Y, and Z. X=66, Y=33, and Z=52. D=E+X+YZ=889455236+66+33+52=889455387. According to A, get the value in the public array: M=23. C=D+M=889455387+23=889455410. B=C+A=889455410+8=889455418. Add a 1 to the left side of B and A to the right side of B, and the final output is the mobile phone number: S=18894554188.

[0129] Through the above method, it is possible to avoid using methods such as MD5 that require large computing power to encrypt the encrypted data. While ensuring the security of the encrypted data, it also improves the efficiency of the data encryption and decryption process.

In the embodiments of the present invention, the electronic device includes but is not limited to a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted terminal, a wearable device, and a pedometer.

[0142] It should be understood that in the embodiment of the present invention, the radio frequency unit 601 can be used for receiving and sending signals during information transmission or communication. Specifically, after receiving downlink data from the base station, it is sent to the processor 610 for processing; in addition, uplink data is sent to the base station. Generally, the radio frequency unit 601 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, etc. In addition, the radio frequency unit 601 can also communicate with the network and other devices through a wireless communication system.

[0144] The audio output unit 603 can convert the audio data received by the RF unit 601 or the network module 602 or stored in the memory 609 into an audio signal and output it as sound. Moreover, the audio output unit 603 can also provide audio output related to a specific function performed by the electronic device 600 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 603 includes a speaker, a buzzer, a receiver, etc.

[0145] The input unit 604 is used to receive audio or video signals. The input unit 604 may include a graphics processor (GPU) 6041 and a microphone 6042, and the graphics processor 6041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The processed image frame can be displayed on the display unit 606. The image frame processed by the graphics processor 6041 can be stored in the memory 609 (or other storage medium) or sent via the radio frequency unit 601 or the network module 602. The microphone 6042 can receive sound and can process such sound into audio data. The processed audio data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 601 in the case of a telephone call mode.

[0146] The electronic device 600 also includes at least one sensor 605, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor includes an ambient light sensor and a proximity sensor, wherein the ambient light sensor can adjust the brightness of the display panel 6061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 6061 and / or the backlight when the electronic device 600 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally three axes), and can detect the magnitude and direction of gravity when stationary, which can be used to identify the posture of the electronic device (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; the sensor 605 can also include a fingerprint sensor, a pressure sensor, an iris sensor, a molecular sensor, a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, etc., which will not be repeated here.

Specifically, the user input unit 607 includes a touch panel 6071 and other input devices 6072. The touch panel 6071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 6071 or near the touch panel 6071 using any suitable object or accessory such as a finger, stylus, etc.). The touch panel 6071 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 610, receives the command sent by the processor 610 and executes it. In addition, the touch panel 6071 can be implemented in various types such as resistive, capacitive, infrared and surface acoustic waves. In addition to the touch panel 6071, the user input unit 607 may also include other input devices 6072. Specifically, other input devices 6072 may include but are not limited to a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, and a joystick, which will not be described in detail here.

[0149] Further, the touch panel 6071 may be covered on the display panel 6061. When the touch panel 6071 detects a touch operation on or near it, it is transmitted to the processor 610 to determine the type of touch event. Then, the processor 610 provides corresponding visual output on the display panel 6061 according to the type of touch event. Figure 6 In the figure, the touch panel 6071 and the display panel 6061 are used as two independent components to realize the input and output functions of the electronic device. However, in some embodiments, the touch panel 6071 and the display panel 6061 can be integrated to realize the input and output functions of the electronic device, which is not limited here.

[0151] The memory 609 can be used to store software programs and various data. The memory 609 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 609 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0152] The processor 610 is the control center of the electronic device. It uses various interfaces and lines to connect various parts of the entire electronic device. By running or executing software programs and / or modules stored in the memory 609 and calling data stored in the memory 609, it performs various functions of the electronic device and processes data, thereby monitoring the electronic device as a whole. The processor 610 may include one or more processing units; preferably, the processor 610 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 610.

[0153] The electronic device 600 may also include a power supply 611 (such as a battery) for supplying power to each component. Preferably, the power supply 611 may be logically connected to the processor 610 through a power management system, thereby implementing functions such as charging, discharging, and power consumption management through the power management system.

[0154] In addition, the electronic device 600 includes some functional modules not shown, which will not be described in detail here.

[0155] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
