The Memory 1005 may be a Random Access Memory (RAM) Memory or a Non-volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in FIG. 1 does not constitute a limitation of the digital load cell anti-cheating device, and may include more or fewer components than shown, or some components in combination, or a different arrangement of components.
As shown in FIG. 1, a memory 1005, identified as one type of computer storage medium, may include an operating system, a network communication module, a user interface module, and a digital load cell anti-cheating program.
In the digital load cell anti-cheating device shown in fig. 1, the network interface 1004 is mainly used for connecting other devices, such as a weighing meter or a server, and performing data communication with the weighing meter or the server; the user interface 1003 is mainly used for connecting user equipment; the digital weighing sensor anti-cheating device calls a digital weighing sensor anti-cheating program stored in the memory 1005 through the processor 1001 and executes the digital weighing sensor anti-cheating method provided by the embodiment of the invention.
Based on the hardware structure, the embodiment of the anti-cheating method of the digital weighing sensor is provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the anti-cheating method for the digital weighing sensor of the invention, and the first embodiment of the anti-cheating method for the digital weighing sensor of the invention is provided.
In a first embodiment, a digital load cell anti-cheating method comprises the steps of:
step S10: and acquiring verification data sent by the statistical terminal, wherein the data format of the verification data is the same as that of the weighing data to be sent.
It should be understood that the implementation subject of this embodiment is the digital weighing sensor anti-cheating device, which has functions of data processing, data communication, program running, and the like, and the digital weighing sensor anti-cheating device may be a digital weighing sensor, or a weighing device including a digital weighing sensor, such as a truck scale, and of course, other devices having similar functions may also be used, and this embodiment is not limited thereto.
It should be understood that the statistical terminal refers to a terminal for receiving weighing data detected by a digital weighing sensor, and after receiving the weighing data, the statistical terminal can perform data analysis, data display and the like based on the weighing data, and is generally a weighing instrument. The digital weighing sensor and the statistical terminal can be connected in a wireless or wired mode to realize data interaction.
It should be noted that the check data may be a random number generated by the statistical terminal, and a data format of the check data is the same as a data format of the weighing data to be sent. Digital load cells are used to generate digital signals, and the load data may be represented in binary form, such as 0111; accordingly, the check data may also be represented in binary form, such as 0100.
During specific implementation, the statistical terminal can send once test data to the digital weighing sensor at regular time, and the digital weighing sensor stores the test data into the memory after receiving the check data. When weighing data transmission is required, the digital weighing sensor can read the memory to obtain verification data. Or the statistical terminal sends a plurality of check data to the digital weighing sensor, and the digital weighing sensor can randomly or according to a preset selection strategy select one check data from the plurality of check data.
Step S20: and merging the checking data and the weighing data to obtain the data to be transmitted.
It should be noted that merging the verification data with the weighing data means combining the verification data and the weighing data. Because the data format of the check data is the same as that of the weighing data, the check data and the weighing data can be directly combined, for example, if the weighing data is represented by 0111, the check data is represented by 0100; the combined data may be 01110100.
After receiving the data 01110100, the statistical terminal splits the data according to a preset rule, thereby obtaining two data, 0111 and 0100. The statistical terminal can judge whether the weighing data is credible by judging whether the verification data is correct or not, and if the verification data is correct, the weighing data is credible; otherwise, it is not trusted. Due to the fact that transmitted data are combined, after the cheating equipment directly modifies the transmitted data, verification data can be changed, and after the statistics terminal checks the verification data, the counting terminal can judge that the transmitted weighing data are not credible.
It should be noted that, the combination mode of the check data and the weighing data also adopts an interpolation mode to combine, and the check data can be inserted into each bit of the weighing data, or the check data can be inserted into the head and the tail of the weighing data. The digital weighing sensor can also switch a combined mode at regular time so as to improve the safety. The combination of the verification data and the weighing data may be set according to the user requirement, which is not limited in this embodiment.
Step S30: and encrypting the data to be transmitted to obtain encrypted data.
It can be understood that, in order to further improve the security of data transmission, the digital weighing sensor encrypts data to be transmitted before data transmission; the encryption algorithm may be a symmetric encryption algorithm or a custom algorithm, and a secret key or a random number related to the encryption process may be issued by the statistical terminal. Even if a cheater intercepts the transmission information, accurate weighing data cannot be obtained.
Step S40: and sending the encrypted data to a statistical terminal.
It should be noted that, the digital weighing sensor sends the encrypted data to the statistical terminal according to a preset communication protocol, for example, a 485 communication protocol. In addition, in order to improve the safety, the communication protocol between the digital weighing sensor and the statistical terminal can be customized.
After receiving the encrypted data, the statistical terminal decrypts the encrypted data according to a corresponding decoding algorithm to obtain transmission data; then, weighing data and checking data are extracted from the transmission data according to a data combination rule; and comparing the check data with the recorded check data, if the check data is consistent with the recorded check data, judging that the weighing data is credible, and if the check data is inconsistent with the recorded check data, judging that the weighing data is not credible. The statistical terminal can also display the analysis result, and when the analysis result is judged to be unreliable, the corresponding digital weighing sensor is marked for further checking by an administrator.
In the first embodiment, the data format of the check data is the same as that of the weighing data to be sent by acquiring the check data sent by the statistical terminal; merging the check data and the weighing data to obtain data to be transmitted; encrypting data to be transmitted to obtain encrypted data; and finally, sending the encrypted data to a statistical terminal. In the embodiment, the verification data is added into the transmission data, and when the transmission data is tampered, the verification data can be modified, so that the tampering condition is identified; meanwhile, the difficulty of data tampering is increased through data encryption, so that digital weighing sensing cheating is prevented, and the reliability of data is improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a cheating-prevention method for a digital weighing sensor according to a second embodiment of the present invention.
In the second embodiment, in order to improve the security of encrypted data, the present embodiment mainly proposes an encryption method for data to be transmitted. Step S30 includes:
step S301: and carrying out hash operation on the data to be transmitted based on a preset hash function to obtain the scattered data.
It should be noted that the predetermined hash function may be MD5 or SHA-256 algorithm, and the hash operation may convert an input with an arbitrary length (i.e. data to be transmitted) into an output with a fixed length (i.e. hashed data). In general, the space of hashed outputs is usually much smaller than the space of inputs, different inputs may hash to the same output, so it is not possible to determine a unique input value from the output, and hashed data can be used to verify whether the data to be transmitted has been tampered with.
Step S302: and encrypting the data to be transmitted based on the preset encryption function and the preset key to obtain ciphertext data.
It can be understood that the digital weighing sensor encrypts the data to be transmitted before data transmission is carried out; the preset encryption function can be a symmetric encryption function or a custom encryption function, so that the security of data transmission is further improved.
Further, before step S302, the method may further include acquiring encryption information and a key sent by the statistical terminal; selecting an encryption function from a preset function library according to encryption information; and taking the encryption function as a preset encryption function and taking the key as a preset key. The key or random number related to the encryption process can be issued by the statistical terminal, so that the secrecy of the encryption mode is improved.
It should be noted that the encryption information may be an identification code, which is used for reference to the encryption function. The digital weighing sensor stores various encryption functions, the statistical terminal can send encryption information and keys at regular time, and the digital weighing sensor encrypts data according to the encryption functions and keys designated by the encryption information after receiving the encryption information.
Step S303: and merging the scattered data and the ciphertext data to obtain encrypted data.
It can be understood that, because the data to be transmitted includes the weighing data and the verification data, the statistical terminal only determines that the weighing data is valid when the verification data is correct. Therefore, even if a cheater intercepts the transmission data, the cheater can only modify the weighing data but cannot modify the verification data; thus, the modified hash data is different from the hash data corresponding to the original transmission data.
In the encryption, the hash data and the data to be transmitted may be encrypted together, and the encrypted data may be used as the encrypted data. The specific encryption function may be set as required, and an existing encryption manner may be adopted, or a customized encryption function may be adopted, so as to improve the security, which is not limited in this embodiment.
In a second embodiment, hash operation is performed on data to be transmitted based on a preset hash function to obtain hash data, data to be transmitted is encrypted based on a preset encryption function and a preset key to obtain ciphertext data, and the hash data and the ciphertext data are combined to obtain encrypted data. When data to be transmitted is encrypted, the hash operation is firstly carried out on the data to be transmitted, and the hash and the verification data are used for carrying out anti-tampering detection on the transmitted weighing data together, so that the cheating condition is prevented; meanwhile, the transmitted data are encrypted, so that the difficulty of cheating is improved.
Referring to fig. 4, fig. 4 is a schematic flow chart of a digital weighing sensor anti-cheating method according to a third embodiment of the invention, which is provided based on the first embodiment and the second embodiment.
In the third embodiment, in order to further improve the prevention of the data to be transmitted from being tampered, the purpose of preventing cheating is achieved by setting the sending process. Step S40 includes:
step S401: the random number is generated based on a preset random number generation function.
Step S402: and generating information to be sent according to the encrypted data and the random number.
Step S403: time information is determined from the random number.
Step S404: and determining interval time according to the time information, and sending the information to be sent to the statistical terminal in an interval time mode.
It is understood that the predetermined random number generation function may be a RAND function or the like, and the digital weighing cell may obtain a random number after running the predetermined random number generation function, and the random number may be a natural number.
In this embodiment, the data to be transmitted is transmitted to the statistical terminal multiple times, wherein the time interval of each transmission is determined according to the random number. The digital weighing sensor generates the random number and the encrypted data together to information to be sent and transmits the information to the statistical terminal, the statistical terminal takes a time interval as a verification parameter, the detected time interval is compared with the received random number, and if the time interval is consistent with the received random number, the transmitted data is judged to be credible; negative, unreliable. Of course, in order to avoid the influence of the communication state on the transmission data, the statistical terminal may set an allowable error range when the detected time interval is compared with the random number. When the error between the two is within the allowable error range, the judgment is reliable.
It should be noted that the correspondence between the random number and the actual transmission time interval may be: the value of the random number is used as the time interval for transmission in milliseconds, or the value of the random number is used as the time interval for transmission in seconds. The specific mode can be set according to the requirement, and the present embodiment is not limited to this.
In order to further improve the reliability of data transmission, in this embodiment, the encrypted data includes first encrypted data and second encrypted data, and the encryption modes used for the first encrypted data and the second encrypted data are different. The data of different encryption modes are transmitted to the statistical terminal, so that the cheating difficulty is increased.
In a specific implementation, step S402 specifically includes: acquiring current time information; generating first information to be sent according to the current time information and the first encrypted data; generating reference time information according to the current time information and the random number; and generating second information to be transmitted according to the reference time information and the second encrypted data.
It should be noted that the current time information may be clock information built in the digital weighing sensor, and in order to ensure validity of time verification, the inside of the statistical terminal should have the same clock information. During specific implementation, a timestamp is generated according to the time information, and the timestamp information is added into the sending information, so that the time information is obtained from the information directly received by the statistical terminal; wherein the time of the timestamp may be the same as the current time or delayed compared to the current time.
In the present embodiment, the number of transmissions is described as two, but the transmission may be performed twice or more. In the embodiment, encrypted data generated in a non-encryption mode and a timestamp determined according to current time information and a random number are adopted in data sent twice, wherein the time difference between the two timestamps is equal to the time interval corresponding to the random number.
In a specific implementation, step S404 is specifically: determining interval time according to the time information; sending the first information to be sent to a statistical terminal, and starting timing; and after the timing time reaches the interval time, sending the second information to be sent to the statistical terminal.
It can be understood that the data weighing sensor can firstly package the first information to be transmitted and the second information to be transmitted before transmitting, and then transmit the first information to be transmitted and the second information to be transmitted. After the first information transmission, an internal timer is started, and after the timing time of the timer reaches the interval time, the second transmission is carried out. The interval time can be as short as possible, so that the cheater spends different time when decrypting different encryption modes, the receiving time of the statistical terminal changes, and the statistical terminal judges that the received data is not credible when detecting that the time information is not equal.
In a third embodiment, a random number is generated based on a preset random number generation function; generating information to be sent according to the encrypted data and the random number; determining time information according to the random number; and determining interval time according to the time information, and sending the information to be sent to the statistical terminal in an interval time mode. The method takes the sending time of the information as the verification parameter, and a cheater usually intercepts the data first and sends the data to the statistical terminal after modifying the data when tampering the data, and the cheating mode can be identified through time verification, so that timely prevention is realized, the cheating possibility is reduced, and the reliability of data transmission is improved.
In addition, an embodiment of the present invention further provides a storage medium, where the storage medium stores a digital weighing sensor anti-cheating program, and the digital weighing sensor anti-cheating program implements the steps of the digital weighing sensor anti-cheating method described above when executed by a processor.
Since the storage medium adopts all technical solutions of all the embodiments, at least all the beneficial effects brought by the technical solutions of the embodiments are achieved, and no further description is given here.
