Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The equipment identity recognition method provided by the application can be applied to an application environment shown in fig. 1, wherein the identity recognition server 104 communicates with the terminal equipment 102 through a network, when a user initiates a recognition request to the identity recognition server, the terminal equipment 102 firstly obtains a recognition application of the user to the identity recognition server, and searches for an equipment seed corresponding to the recognition application; then generating an access request according to the equipment seeds; an access request is sent to the identification server 104. The identity recognition server 104 firstly obtains an access request submitted by the terminal equipment 102; analyzing the access request, and identifying the data type carried in the access request; when the access request does not carry the equipment seed or the equipment information, generating an identification failure message; when the access request carries the equipment seed and the equipment information, searching the equipment information corresponding to the equipment in the history record according to the equipment seed, and extracting the unique equipment number in the searched equipment information; and identifying the terminal equipment 102 according to the obtained equipment unique number. The terminal device 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers.
As shown in fig. 2, in one embodiment, the device identity recognition method of the present application is implemented by an identity recognition server, and specifically includes the following steps:
s210, obtaining an access request of the equipment.
And S230, analyzing the access request and identifying the data type carried in the access request.
The equipment is to-be-identified equipment, and the identification equipment specifically identifies equipment information corresponding to the current equipment and generates a unique, stable and unchangeable equipment unique number for the equipment. The equipment to be identified is provided with a front end of a corresponding identity identification server, the equipment to be identified can generate an access request through the front end and send the access request to the identity identification server through a network to request the corresponding service of the server, the access request carries equipment information of the equipment, and the access request is generated by the front end corresponding to the server and comprises equipment seeds which are generated in advance by the front end and stored on the equipment to be identified. The identification server can analyze the access request of the equipment, identify the data type carried in the access request and determine whether the equipment information or the equipment seed is contained in the access request.
And S250, when the access request does not carry the equipment seed or the equipment information, generating an identification failure message, wherein the equipment seed is generated based on the UUID corresponding to the equipment and corresponds to the equipment.
UUID is an abbreviation for universal Unique Identifier (Universally Unique Identifier), a standard for software construction, and is also part of the open software foundation organization in the field of distributed computing environments. The aim is to enable all elements in the distributed system to have unique identification information without specifying the identification information through a central control end. In this way, everyone can create a UUID that does not conflict with others. The device seed is generated by the front end of the server based on the UUID corresponding to the device, corresponds to the device, has global uniqueness, and can ensure that when the device is identified according to the device seed, the identification result is also unique. When the scene is a simulation request or the device environment of the current device to be identified causes that the front end cannot complete the task of uploading the device information, a situation that the access request does not include the device seed or does not include the device information occurs, in this case, the device cannot be identified, and at this time, a corresponding identification failure message can be generated.
And S270, when the access request carries the equipment seed and the equipment information, searching the equipment information corresponding to the equipment in the history record according to the equipment seed, and extracting the unique equipment number in the searched equipment information.
The unique serial number of the equipment is a unique, stable and unchangeable serial number generated for the equipment based on the equipment seed. The equipment identity identification is the unique equipment number corresponding to the current equipment. When the access request contains the equipment seed, the equipment information corresponding to the equipment to be identified in the history record can be directly searched according to the equipment seed due to the uniqueness of the equipment seed, and then the equipment unique number of the equipment is extracted from the equipment information corresponding to the equipment to be identified in the history record. In particular, when the history record does not contain the device information of the current device to be identified, that is, the history record of the device is not contained in the history record of the server when the device is accessed for the first time, the unique number of the device can be directly generated according to the device seed of the device.
And S290, identifying the equipment according to the obtained unique equipment number.
The unique serial number of the equipment is a unique, stable and unchangeable serial number generated for the equipment based on the equipment seed. The equipment can be directly identified through the found unique equipment number. Further, after the unique number of the current device is obtained, the account number logged in on the current device can be searched based on the unique number of the device, the number of the account numbers logged in on the current device is judged, if a plurality of account numbers are logged in on the device, a person using the device can be considered to be maliciously logged in, and then the login behavior of the device is limited to a certain extent. Furthermore, the interface calling condition of the equipment can be statistically analyzed based on the unique serial number of the equipment, potential threats can be found, and the problem can be solved in time.
In the equipment identity identification method, the server firstly acquires an access request of the equipment; analyzing the access request, and identifying the data type carried in the access request; when the access request does not carry the equipment seed or the equipment information, generating an identification failure message; when the access request carries the equipment seed and the equipment information, searching the equipment information corresponding to the equipment in the history record according to the equipment seed, and extracting the unique equipment number in the searched equipment information; and identifying the equipment according to the obtained unique equipment number. According to the equipment identity identification method, in addition to the equipment information, the equipment identity identification is assisted by generating the equipment seeds by means of the UUID based on the equipment, the problems that the equipment identity cannot be identified and one equipment is identified as different equipment are solved, and the equipment identity identification accuracy is improved.
In one embodiment, step S270 includes:
and when the access request carries the equipment seed and the equipment information, searching historical equipment information corresponding to the equipment according to the equipment seed.
And when the historical equipment information is not empty, extracting the equipment unique number in the equipment information corresponding to the equipment in the historical record as the equipment unique number of the equipment.
And when the historical device information is empty, acquiring the similarity between the device information and each device information in the historical record, and searching the device information in the historical record corresponding to the maximum value of the similarity.
And when the maximum similarity is greater than or equal to the preset similarity threshold, taking the unique equipment number in the equipment information in the history record corresponding to the maximum similarity as the unique equipment number of the equipment.
And when the maximum value of the similarity is smaller than a preset similarity threshold value, generating the unique equipment number of the equipment according to the equipment seed of the equipment.
Specifically, the server may first search for a corresponding history record based on the device seed, so as to search for a history device record of the corresponding device, and thus confirm the unique device number of the access device, thereby performing device identification. However, when the history device record corresponding to the current device is not found, the server may find the similarity between the current device information and each device information in the history record. And then searching the device information with the maximum similarity with the device information of the device to be identified in the history, if the similarity exceeds a preset similarity threshold, determining that the device corresponding to the device information in the history and the current device to be identified are possibly the same device, and acquiring the unique device number of the device to be identified through the device information in the history. And when the maximum value of the similarity is smaller than the preset similarity threshold, it indicates that no equipment information of the equipment to be identified exists in the history record, and at this time, the equipment unique number of the equipment can be generated according to the equipment seed of the equipment. Wherein the preset similarity threshold can be determined by the recognition success rate of the test equipment. In one embodiment, for finding the similarity between the device information, the server converts the text information of the device information into character string information through a simhash signature. The device information of the device to be identified and the device information in the history record can be converted into character strings respectively through simhash signatures of the device information and the device information in the history record, then the hamming distance between the device information of the device to be identified and each device information in the history record is obtained, and the similarity between the device information of the device to be identified and each device information in the history record is obtained through the hamming distance. The hamming distance is the number of different characters at the corresponding positions of two character strings. In other words, it is the number of characters that need to be replaced to convert one string into another. When the access request does not carry the device seed, the current device to be accessed can be identified through the device information in the history record.
As shown in fig. 3, in one embodiment, the device identity identification method of the present application is implemented by a terminal device, and specifically includes the following steps:

And S430, generating an access request according to the equipment seed.
S450, sending the access request to an identity recognition server.
The embodiment can be specifically realized by a front-end software program installed on the terminal equipment by a user, and when the user starts the front-end program and initiates an identification application to the identity recognition server by clicking a corresponding key, the terminal equipment acquires the identification application to the identity recognition server initiated by the user and then searches for an equipment seed stored on the equipment. And generating a corresponding access request through the equipment seed, and sending the access request to an identity recognition server for corresponding identity recognition.
In one embodiment, step S410 is preceded by:
and generating a UUID corresponding to the equipment according to the UUID algorithm.
And generating an equipment seed according to the UUID.
The device seed is stored to various storage locations within the device.
Before a user initiates an identification request to an identification server, a device seed corresponding to the current device can be generated on the current device through a front end. Specifically, a UUID corresponding to the device can be generated through a UUID algorithm, and then a device seed is generated through the UUID. And the device seeds are stored in each storage position in the device, so that the device seeds can be prevented from being lost due to operations such as data deletion or system reinstallation, and the stability of device identification is improved. In one embodiment, the UUID algorithm may obtain the current date and the current time on the device to be identified, the machine code of the device in the device information, and the clock sequence through the front end on the device to be identified, and then generate the UUID corresponding to the device. In one embodiment, a UUID corresponding to a device may be generated by jdk (Java development kit) in Java, and then a device seed may be generated by the UUID.
In one embodiment, S430 includes:
and S432, generating an identity identification token according to the equipment seed.
And S434, generating an access request according to the identity token.
In another embodiment, the device seed is encrypted before generating the identification token based on the device seed, and the identification token is generated based on the encrypted device seed.
After generating the device seed corresponding to the device to be identified, the device seed can be packaged in the identity identification token to be used as a part of the identity identification token, then the corresponding access request is generated through the identity identification token, and the device seed is packaged as a part of the identity identification token, so that the concealment of the device seed can be effectively improved.
In one embodiment, before generating the identification token according to the device seed, the method further includes: and generating the identity identification token according to the equipment seed. Generating an identification token from the device seed comprises: and generating an identity identification token according to the encrypted equipment seed. The equipment seed can be encrypted and then an identity identification token is generated, so that the safety of the equipment seed is improved. And further encrypting the equipment seeds, the safety of the equipment seeds can be better guaranteed.
