Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
The terminal identification determining method of the embodiments provided in the present application may be applied to an application environment as shown in fig. 1, where the application environment includes a terminal 10 and a server 20, and the terminal 10 may communicate with the server 20 through a network. Specifically, an application (e.g., a video application) may be installed on the terminal 10, and when the application is first run on the terminal 10, the terminal 10 may send a globally unique identifier request to the server 20, and the server 20 may be a background server corresponding to the application, and the server 20 may be configured to respond to the globally unique identifier request and interact and communicate with the terminal 10 where the application is located. That is, after receiving the global unique identifier request sent by the terminal 10 and responding, the server 20 may determine the unique private key corresponding to the terminal 10, determine the corresponding public key based on the unique private key, generate the global unique identifier corresponding to the terminal on the basis of the public key, that is, the global unique identifier serves as a terminal identifier, and the global unique identifier that may be determined through the above process may uniquely identify the terminal.
The server 20 may be implemented as a stand-alone server or as a server cluster comprising a plurality of servers. The terminal 10 may be any device capable of implementing intelligent input and output and installing and running applications, for example, the terminal may be a television terminal, a smart phone, a tablet computer, a vehicle-mounted computer, a wearable smart device, and the like.
In one embodiment, as shown in fig. 2, a terminal identification determination method is provided. The method is exemplified by being applied to the server 20 in fig. 1, and includes the following steps S210 to S230.
S210: receiving a globally unique identifier request sent by a terminal.
The globally Unique identifier, i.e. guid (global Unique identifier), is a kind of generated identifier, and can be used to uniquely identify the object. In this embodiment, to distinguish different terminals, a unique identifier may be created for a terminal by an algorithm, the GUID may be the unique identifier, each terminal has its own unique identifier, and the global unique identifier of the terminal may uniquely identify the terminal.
In an example, the terminal may be a television terminal, and taking the terminal as a television terminal as an example, the terminal identifier determining method is a television terminal identifier determining method, where the television terminal may be a smart television or a television box.
The terminal can be provided with applications, such as video applications, and users can operate and control the video applications on the terminal, so that video playing and the like can be realized. When the terminal starts the application for the first time, a global unique identifier request can be sent to a background corresponding to the application, namely the server, so as to request the global unique identifier. The terminal can receive the globally unique identifier returned by the server, and any request sent to the server subsequently carries the globally unique identifier. And when the server receives the global unique identifier request sent by the terminal, responding to the request to execute the corresponding global unique identifier generation process.
S220: and responding to the request of the global unique identifier to generate a unique private key corresponding to the terminal.
The server receives the global unique identifier request and then responds, firstly, the unique private key corresponding to the terminal needs to be generated, namely, the unique private key uniquely corresponds to the terminal, and the condition that the same private key corresponds to a plurality of terminals can be avoided.
In an example, the generating of the unique private key corresponding to the terminal may be randomly generating the unique private key corresponding to the terminal, that is, the private key may be randomly generated. In one example, the private key may be a 32-byte number, the private key is private, poorly identifiable, and highly secure.
S230: and determining a public key corresponding to the unique private key according to the unique private key.
The private key and the public key are paired, and after the private key is determined, the corresponding public key can also be determined, and the public key is public. In particular, the private key may be processed through an encryption algorithm to determine the corresponding public key. Namely, the public key can be determined through the private key, but the private key cannot be obtained through reverse calculation of the public key, so that the data security is improved.
The unique private key can uniquely correspond to the terminal and has uniqueness, so that the uniqueness of the public key determined based on the unique private key can be ensured.
S240: and generating a corresponding globally unique identifier of the terminal based on the public key.
After the public key is determined, a global unique identifier corresponding to the terminal can be generated based on the public key, that is, a terminal identifier (the global unique identifier serves as the terminal identifier) is generated, the terminal identifier is determined, the terminal can be uniquely marked through the global unique identifier, and the situation that the terminal identifiers are the same can be avoided.
In the terminal identification determining method, in the process of determining the terminal identification, when a global unique identifier request sent by the terminal is received, a unique private key corresponding to the terminal can be generated in response to the global unique identifier request, namely, the unique private key is uniquely corresponding to the terminal. Due to the uniqueness of the private key, the uniqueness of the public key obtained based on the unique private key can be ensured, and further, on the basis of the public key, the global unique identifier corresponding to the terminal is generated, that is, the uniqueness of the global unique identifier corresponding to the terminal can be ensured, that is, the global unique identifier corresponding to the terminal can be ensured to uniquely correspond to one terminal.
In an embodiment, after generating the globally unique identifier corresponding to the terminal based on the public key, the method may further include: and counting the global unique identifiers corresponding to the terminals to obtain the quantity of the global unique identifiers.
In the server, every time a global unique identifier request sent by a terminal is received to perform a global unique identifier generation process, a global unique identifier corresponding to the terminal is correspondingly obtained. After obtaining the global unique identifier corresponding to a terminal, the global unique identifier corresponding to the terminal can be recorded. The global unique identifier corresponding to each terminal obtained in the server can be counted subsequently, and the number of the global unique identifiers is obtained. Because the globally unique identifier has uniqueness, duplication is avoided, and therefore, the accuracy of the number of the globally unique identifiers can be improved. Moreover, the number of the globally unique identifiers corresponds to the number of the terminals, i.e. the number of users using the application can be accurately determined by the number of the globally unique identifiers.
As shown in fig. 3, in one embodiment, the globally unique identifier request carries an application attribute information value, i.e., an application corresponding attribute information value. When the application is started for the first time, the terminal can send a global unique identifier request to the background, and the global unique identifier request carries the application attribute information value to be used as a data basis for the server to generate the global unique identifier.
The step S240 of generating the globally unique identifier corresponding to the terminal based on the public key includes steps S341 to S344.
S341: and carrying out hash processing on the public key to determine an initial hash value of the public key.
Hashing refers to the transformation of an input into a fixed length output, which is a hash value, and may also be referred to as a hash value, by a hashing algorithm, which may be understood as a kind of compression mapping. In the process of generating the globally unique identifier corresponding to the terminal based on the public key, the public key is subjected to hash processing to determine an initial hash value, wherein the input of the hash processing is the public key, and the output is the initial hash value.
S342: an intermediate hash value is determined based on the application attribute information value and the initial hash value of the public key.
And processing the initial hash value by using the application attribute information value to obtain an intermediate hash value. On one hand, the information quantity of the intermediate hash value is ensured, and the uniqueness is enhanced. And on the other hand, the relevance of the intermediate hash value to the application attribute information and the initial hash value respectively is ensured.
In one example, an intermediate hash value may be obtained by adding the application attribute information value to the initial hash value of the public key before the application attribute information value, i.e., combining the application attribute information value and the initial hash value to obtain the intermediate hash value, and the determined intermediate hash value may include both the initial hash value and the application attribute information value before the initial hash value.
For example, the initial hash value is 0x010866776006953D5567439E5E39F86A0D273be, and the application attribute information value is 0x00, where 0x in the initial hash value and the application attribute information value represents 16 systems, and the actual value is a number after 0x, then the resulting intermediate hash value is 0x00010866776006953D5567439E5E39F86A0D273 be. In one example, the application attribute information value may be an application version number (the application version number is a numeric value).
S343: and carrying out hash processing on the intermediate hash value to determine a target hash value.
After the intermediate hash value is obtained, in order to further improve the security and the uniqueness, hash processing needs to be performed on the intermediate hash value to obtain a target hash value. Here, the input of the hash process is an intermediate hash value, and the output is a target hash value.
S344: and generating a globally unique identifier corresponding to the terminal based on the intermediate hash value and the target hash value.
In this embodiment, the determination of the globally unique identifier is performed in conjunction with the intermediate hash value and the target hash value, i.e. the determination of the globally unique identifier is related to both the intermediate hash value and the target hash value, to ensure the security and uniqueness thereof.
In one embodiment, the step S341 of performing a hash process on the public key and determining an initial hash value of the public key includes: performing hash processing on the public key based on a first hash algorithm to determine an original hash value; and carrying out hash processing on the original hash value based on a second hash algorithm to determine an initial hash value.
And respectively carrying out hash processing on the public key and the original hash value by adopting different hash algorithms to obtain a processed hash value. In one example, the first hash algorithm may be a SHA-256 hash algorithm and the second hash algorithm may be a RIPEMD-160 hash algorithm.
In one embodiment, the step S343 of performing hash processing on the intermediate hash value to determine a target hash value includes: performing hash processing on the intermediate hash value based on a third hash algorithm to determine a processed intermediate hash value; and performing hash processing on the processed intermediate hash value based on a third hash algorithm to determine a target hash value.
And performing hash processing on the intermediate hash value twice by adopting the same hash algorithm, namely performing hash processing on the intermediate hash value once by adopting a third hash algorithm, and performing hash processing on the processed intermediate hash value once by utilizing the third hash algorithm to obtain a target hash value. In one example, the third hash algorithm may be the same as the first hash algorithm described above, and the third hash algorithm may be a SHA-256 hash algorithm.
In one embodiment, the step S344 of generating the globally unique identifier corresponding to the terminal based on the intermediate hash value and the target hash value includes: selecting a preset number of bytes from the target hash value, adding the bytes into the intermediate hash value, and obtaining a hash value to be processed; and encoding the hash value to be processed, and determining the global unique identifier corresponding to the terminal.
Namely, a preset number of bytes in the target hash value are selected and combined with the intermediate hash value to obtain a hash value to be processed, and the preset number of bytes in the target hash value is selected behind the intermediate hash value. In this way, the intermediate hash value is further transformed by using at least part of data in the target hash value, so that the obtained hash value to be processed is safer, and the uniqueness of the hash value is enhanced. Which is subsequently encoded to determine the globally unique identifier.
In one embodiment, the hash value to be processed is obtained after a preset number of bytes are arbitrarily selected from the target hash value and added to the intermediate hash value, i.e., the bytes after the intermediate hash value of the added value are arbitrarily selected from the target hash value. Therefore, the diversity of the hash values to be processed can be improved.
In one example, the hash value to be processed may be obtained after a preset number of bytes are selected from the target hash value and added to the intermediate hash value. For example, the target hash value is 0xE61967F63C7DD183914A4AE452C9F6AD5F462CE3D277798075B107615C1A8A3E, the intermediate hash value is 0x00010866776006953D5567439E5E39F86A0D273be, after the first preset number of bytes in the target hash value (the preset number may be 4 in one example, then the first preset number of bytes in the target hash value is the first four bytes, i.e., E61967F6) is added to the intermediate hash value, the hash value to be processed is 0x00010866776006953D5567439E5E39F86A0D273be 61967F 6.
In one embodiment, the BASE58 encoding algorithm may be used to encode the hash value to be processed to determine the globally unique identifier corresponding to the terminal.
In one embodiment, determining the public key corresponding to the unique private key according to the unique private key includes: and encrypting the unique private key based on a preset encryption algorithm to determine a public key.
On the basis of determining the unique private key, the private key can be encrypted through an encryption algorithm to obtain a public key, and the private key cannot be reversely calculated through the public key, so that the information safety can be ensured. It will be appreciated that the public key is unique, thus ensuring the uniqueness of the globally unique identifier that is subsequently derived.
In one embodiment, the predetermined encryption algorithm may be an asymmetric encryption algorithm.
In the symmetric encryption algorithm, a data sender processes a plaintext (original data) and an encryption key together through a special encryption algorithm, and then the plaintext and the encryption key are changed into a complex encryption ciphertext to be sent out. After the receiver receives the ciphertext, if the receiver wants to decode the original text, the receiver needs to decrypt the ciphertext by using the key used for encryption and the inverse algorithm of the same algorithm so as to recover the ciphertext into readable plaintext. In the symmetric encryption algorithm, only one key is used, both the sender and the receiver use the key to encrypt and decrypt data, and the decryptor needs to know the encryption key in advance, so that the security is insufficient. The asymmetric encryption algorithm requires two keys: public key (publickey) and private key (privatekey). The public key and the private key are a pair, and if the public key is used for encrypting data, the corresponding private key is needed for decryption; if the private key is used to encrypt data, the corresponding public key is needed to decrypt the data. Two different keys are used for encryption and decryption, so that the security can be improved.
In one example, the asymmetric encryption algorithm may employ an elliptic curve encryption algorithm (secp256k 1).
In one embodiment, generating a unique private key corresponding to the terminal includes: generating a unique random number corresponding to the terminal at random by a random number generator; and taking the unique random number as a unique private key corresponding to the terminal.
The private key is randomly generated and is unique, the private keys generated by the server are unique for different terminals, and the unique private keys can uniquely correspond to the terminals. In the embodiment, a unique random number is randomly generated by the random number generator to serve as a unique private key, so that the method is fast and accurate.
In one embodiment, after generating the globally unique identifier corresponding to the terminal, the method further includes: the globally unique identifier is returned to the terminal.
After the server generates the globally unique identifier corresponding to the terminal, the server can return the globally unique identifier to the corresponding terminal. The terminal receives the global unique identifier, and any request sent to the server subsequently can carry the corresponding global unique identifier so as to facilitate server statistics and recording.
The following describes a procedure of the above terminal identifier determining method in a specific embodiment. With the invention of digital encryption currency such as bitcoin, a brand new decentralized distributed infrastructure called as a block chain and a data operation mode are gradually developed. Decentralization, distribution, programmability, high security and reliability are remarkable characteristics of the block chain technology, and are particularly suitable for the fields of macroscopic systems such as data storage, financial transactions and the like. The block chain is a bottom layer technology derived from a bitcoin, is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence, and is guaranteed to be non-falsifiable and non-counterfeitable in a cryptographic mode to realize a decentralized distributed account book. The above terminal identity determination process may be understood as a process of determining a terminal identity based on a block chain.
Taking a television terminal as an example, as shown in fig. 4 and 5, firstly, a user may install a video application (i.e., a video APP) at the television terminal, and when the user starts the video application on the television terminal for the first time, the video application may send a GUID request (a globally unique identifier request) to a background of the video application through the terminal, where the GUID request may carry a version number corresponding to the video application. The video application on the terminal has a corresponding cache, and in the use process of the video application, cache information, such as information of pictures, videos and the like, can be generated in the cache. If the video application is operated for the first time, the cache information is not stored in the cache, whether the video application is started for the first time or not can be judged by detecting whether the cache information exists in the cache, if not, the video application represents the first start and sends a GUID request to the next day, otherwise, the video application represents the non-first start and does not need to send the GUID request.
Then, the background of the video application responds to the global unique identifier request, a 32-byte unique random number corresponding to the television terminal is randomly generated through a random number generator, and the unique random number is used as a unique private key corresponding to the television terminal, as shown in fig. 6. For example, the unique private key generated may be 0x28FD4A7B6a307F426a94F8114701E7C8E774E7E9a47E2C2035DB23a 206321726.
Secondly, a public key corresponding to the unique private key is determined based on an elliptic curve encryption algorithm (secp256k 1). For example, the public key determined based on the unique private key described above may be 0x0460863AD64a87AE8D2FE83C1AF1a8403CB53F53E486D8511DAD8a04887E5B23522CD470243453a299FA9E77237716103ABC11A1DF38855ED6F2EE187E9C582BB 7.
And performing hash processing on the public key based on the SHA-256 hash algorithm to determine an original hash value, and performing hash processing on the original hash value based on the RIPEMD-160 hash algorithm to determine an initial hash value. For example, the determined raw hash value may be 0x600FFE422B4E00731a59557A5CCA46CC183944191006324a447BDB2D98D4B 408. The initial hash value determined based on the original hash value may be: 0x010866776006953D5567439E5E39F86A0D273 BEE.
And then, before adding the application version number to the initial hash value of the public key, determining an intermediate hash value. As shown in fig. 6, the application version number may be 0x00(0x identifies 16 th, and its specific value is 00), and when it is added before the initial hash value, the determined intermediate hash value is 0x00010866776006953D5567439E5E39F86A0D273 BEE. And performing hash processing on the intermediate hash value by using an SHA-256 hash algorithm to determine a processed intermediate hash value, and performing hash processing on the processed intermediate hash value based on the SHA-256 hash algorithm to determine a target hash value. Namely, SHA-256 hash processing is carried out on the intermediate hash value for 2 times to obtain a target hash value. The obtained target hash value is 0xE61967F63C7DD183914A4AE452C9F6AD5F462CE3D277798075B107615C1A8 A3E.
And thirdly, after the first four bytes in the target hash value are added to the intermediate hash value, obtaining the hash value to be processed, wherein the four bytes can be used for verification. The first four bytes in the selected target hash value are E61967F6, and after the first four bytes are added to the intermediate hash value, the obtained hash value to be processed is 0x00010866776006953D5567439E5E39F86A0D273BEEE61967F 6.
And coding the hash value to be processed based on a BASE58 coding algorithm, and determining the GUID corresponding to the television terminal, wherein the GUID corresponding to the television terminal is used as the television terminal identifier. The globally unique identifier corresponding to the determined television terminal may be 16UwLL9Risc3 qfpqbuvbkofhbmq 7 wMtjvM. The terminal where the video application is located can be uniquely identified through the globally unique identifier. And finally, returning the obtained globally unique identifier to the television terminal.
In this way, the embodiment of the application does not rely on the parameters uploaded by the television terminal to determine the identifier, but determines the globally unique identifier through the above process, so as to ensure the uniqueness of the television terminal identifier. Based on the characteristics of non-tampering and uniqueness of the block chain, the process of determining the television terminal identification can effectively solve the problems that a plurality of television terminals correspond to the same GUID and a single user cannot correspond to the single GUID.
It should be understood that although the various steps in the flow charts of fig. 2-5 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2-5 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
As shown in fig. 7, a terminal identifier determining apparatus according to an embodiment is provided, where the apparatus may be the server 20 in fig. 1, and may also be disposed in the server 20 in fig. 1, and the apparatus includes:
a request receiving module 710, configured to receive a globally unique identifier request sent by a terminal;
