Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
FIG. 1 shows a flow diagram of an embodiment of the device ID generation method of the present invention, which is performed by a computing device. In embodiments of the present invention, the storage space of the computing device has stored therein executable instructions that may cause the processor to perform the device ID generation method. The computing device may be a terminal device, as shown in fig. 1, the method comprising the steps of:
step 110: and acquiring hardware information of the equipment, wherein the hardware information at least comprises an equipment serial number and equipment ROOT authority.
The hardware information of the device is basic attributes of hardware constituting the device, such as a device serial number and a device ROOT authority, and the hardware information may generally include a plurality of basic attributes of the device hardware. The hardware information of the device may be obtained in various ways, for example, by accessing a motherboard chip of the device.
Step 120: and generating a hardware information character string according to the hardware information.
The hardware information character string containing the hardware information can be generated according to the hardware information of the equipment. The plurality of basic attributes of the hardware of the device can be integrated into one character string through the hardware information character string.
In a preferred implementation manner of the embodiment of the present invention, the hardware information may further include: one or more of the size of the device memory, the size of the device disk, the number of the device CPUs, the type of the device and the type of the device CPUs. The more kinds of hardware information, the less easily the subsequently generated device ID is emulated.
In a preferred mode of the embodiment of the present invention, the step 120 may further include the steps of:
step 121: and sequencing the hardware information according to a preset rule.
The preset rule may include multiple types, for example, the hardware information includes basic attributes of 3 pieces of device hardware, such as a device serial number, a device ROOT authority, a size of a disk, and the like, and the preset rule may be, for example, sequentially ordered according to the size of the disk, the device serial number, and the device ROOT authority, and may also be sequentially ordered according to the device serial number, the device ROOT authority, and the size of the disk. The more the kinds of hardware information are, the more the possibility is given to the preset rule, and the less easily the device ID generated later is imitated.
Step 122: and generating a hardware information character string according to the sorted hardware information.
The hardware information character string can be generated according to the sorted hardware information in various ways. For example, a character string of each basic attribute may be generated according to a plurality of basic attributes of the device hardware, and then the character strings of each basic attribute may be connected end to end according to a result of sorting the hardware information to generate a hardware information character string.
In some other embodiments of the present invention, step 120 may further include the following steps:
step a 1: and sequencing the hardware information according to a preset rule.
The preset rule may include multiple types, for example, the hardware information includes basic attributes of 3 pieces of device hardware, such as a device serial number, a device ROOT authority, a size of a disk, and the like, and the preset rule may be, for example, sequentially ordered according to the size of the disk, the device serial number, and the device ROOT authority, and may also be sequentially ordered according to the device serial number, the device ROOT authority, and the size of the disk. The more the kinds of hardware information are, the more the possibility is given to the preset rule, and the less easily the device ID generated later is imitated.
Step a 2: a first string for each base attribute is generated based on a plurality of base attributes of the device hardware.
Wherein each first character string corresponds to a basic attribute. For example, the first character string is "4 GB", and the basic attribute of the device hardware corresponding to the first character string is "device memory size"; the first character string is "i 80C 88A", and the basic attribute of the corresponding device hardware is "CPU model".
Step a 3: and extracting characters at preset positions in the first character string of each basic attribute to generate a second character string of each basic attribute.
The hardware information may include, for example, basic attributes of 3 pieces of device hardware, such as a device serial number, a device ROOT authority, and a size of a disk, where a first character string of the device serial number is "abcdef", a first character string of the device ROOT authority is "high", and a first character string of the size of the disk is "128 GB". The preset positions are even positions, namely 2,4,6,8 … … and the like. Then the second character strings of the device serial number, the device ROOT authority and the size of the disk are respectively: "bdf", "ih", "2G".
Step a 4: and generating a hardware information character string according to the sorting and the second character string of each basic attribute.
The second character strings of each basic attribute may be connected end to end according to the result of sorting the hardware information, so as to generate the hardware information character strings. For example, the hardware information includes basic attributes of 3 pieces of device hardware, such as a device serial number, a device ROOT authority, a size of a disk, and the like, and the result of sorting the hardware information is the device serial number, the size of the disk, and the device ROOT authority, and if second character strings of the device serial number, the size of the disk, and the device ROOT authority are "bdf", "2G", and "ih", respectively, the hardware information character string is "bdf 2 Gih".
In this embodiment, a second character string of each basic attribute may be generated by extracting a character at a preset position in the first character string of each basic attribute; generating a hardware information character string according to the second character string and the sequencing result of the hardware information; because the preset position of the first character string can be customized by related technicians, the second character string generated according to the first character string is not unique, and the hardware information character string generated according to the second character string is not easy to imitate.
Step 130: and generating an MD5 value of the hardware information character string, wherein the MD5 value is a character string with 32 bits.
MD5, Message Digest Algorithm 5, is an encryption Algorithm widely used in the field of computer security. The MD5 can compress large capacity information into fixed-length character strings, and the MD5 value generated by the MD5 can be changed greatly as long as the original data is slightly changed. By generating the MD5 value of the hardware information string, the generated MD5 value can be in one-to-one correspondence with the hardware information string, and as long as the hardware information string is changed, the MD5 value generated according to the hardware information string is changed, and the MD5 value of the hardware information string can be a 32-bit string.
Step 140: and dividing the MD5 value according to a preset dividing format, and determining the divided MD5 value as the device ID.
The preset segmentation format may include multiple types. For example, the MD5 value may be split according to a preset split format of 8-4-4-16, and the split MD5 value may be determined as the device ID. According to different application scenarios, the MD5 value may also be divided in any other manner, for example, the MD5 value is divided according to a preset division format of 8-8-16, and the divided MD5 value is determined as the device ID, which is not limited in this embodiment of the present invention.
The embodiment of the invention can generate the hardware information character string by acquiring the hardware information of the equipment, wherein the hardware information at least comprises the equipment serial number and the equipment ROOT authority; and further generating an MD5 value of the hardware information character string, dividing the MD5 value according to a preset division format, and determining the divided MD5 value as the device ID, so that the generation process of the device ID is complex and is not easy to imitate.
FIG. 2 is a flow chart illustrating another embodiment of the device ID generation method of the present invention, as performed by a computing device. In embodiments of the present invention, the storage space of the computing device has stored therein executable instructions that may cause the processor to perform the device ID generation method. The computing device may be a terminal device, as shown in fig. 2, and this embodiment is different from the foregoing embodiment in that, after the step 140 divides the MD5 value according to a preset division format and determines the divided MD5 value as the device ID, the device ID generation method further includes:
step 150: and storing the equipment ID into a preset system storage area.
The device ID can be effectively stored by storing the device ID in the preset system storage area, so that the device ID can be directly acquired by accessing the preset system storage area when the device ID needs to be acquired.
In a preferred implementation manner of the embodiment of the present invention, the system storage area includes: a shared region of the android operating system based device, and/or a key string storage region of the IOS operating system based device.
Wherein the shared region is located in an internal storage space of the android operating system based device. The access right of the shared area can be controlled, so that the shared area can share data among different applications. The Key string, Key Chain, is a password management system in an operating system developed by apple, and can store various types of password data.
According to the embodiment of the invention, the device ID is stored in the preset system storage area, so that the device ID can be directly acquired by accessing the preset system storage area when the device ID is required to be acquired. The preset storage area can comprise a shared area of the equipment based on the android operating system and/or a key string storage area of the equipment based on the IOS operating system, so that different storage modes can be configured for the equipment ID according to different equipment, and the storage and acquisition of the equipment ID are more convenient.

In embodiments of the present invention, the storage space of the computing device has stored therein executable instructions that may cause the processor to perform the device binding method. The computing device may be a server device, as shown in fig. 3, the method comprising the steps of:
step 210: and receiving login information of a user and an equipment ID of equipment for the user to perform login operation, wherein the equipment ID is generated according to the equipment ID generation method.
The computing device may receive login information of the user and a device ID of a device on which the user performs a login operation, where the device ID may be generated according to the device ID generation method in the above embodiment.
Step 220: and if the login information and the equipment ID are not bound, receiving the biological characteristics of the user to authenticate the identity of the user.
After receiving the login information of the user and the device ID of the device on which the user performs the login operation, the computing device may determine whether the login information is bound to the device ID. If the login information and the device ID are not bound, the terminal device can be prompted to acquire the biological characteristics of the user. After receiving the user's biometric feature sent by the terminal device, the identity of the user may be authenticated according to the user's biometric feature. The process of authenticating the identity of the user is to compare the received biological characteristics of the user with the stored biological characteristics of the user, if the received biological characteristics of the user are consistent with the stored biological characteristics of the user, the identity authentication of the user is successful, and if the received biological characteristics of the user are inconsistent with the stored biological characteristics of the user, the identity authentication of the user is unsuccessful.
In a preferred implementation of the embodiments of the present invention, the biometric features further comprise: one or more of fingerprint information, iris information, face information and voiceprint information enable the identity of the user to be authenticated through multiple biological characteristics, and the safety of authentication of the identity of the user is enhanced.
Step 230: and if the identity authentication of the user is successful, binding the login information with the equipment ID, generating a Token according to the binding result, and returning the Token to the equipment for the user to perform login operation.
If the identity authentication of the user is successful, the computing device can bind the login information of the user with the device ID, further can generate Token according to the binding result, and returns the generated Token to the device for the user to perform login operation, so as to complete the login operation of the user.
The Token generated according to the result of binding the login information and the device ID may be a JSON Web Token. JSON Web Token is a JSON-based open standard that can pass assertions between Web application environments for passing authenticated user identity information between identity providers and service providers.
The embodiment of the invention can judge whether the login information and the equipment ID are bound or not by receiving the login information of the user and the equipment ID of the equipment for the login operation of the user; if the login information and the equipment ID are not bound, receiving the biological characteristics of the user to authenticate the identity of the user; if the identity authentication of the user is successful, the login information and the device ID can be bound, a Token is generated according to the binding result, and the Token is returned to the device for the user to perform login operation. It can be seen that the identity of the user can be effectively identified by receiving the biological characteristics of the user to authenticate the identity of the user, the login information of the user is bound with the device ID, and Token is generated to return the device for the user to log in so as to complete the login of the user, so that the login security of the user can be improved.
