In the validity verification method, each external data comprises a plurality of data segments and a plurality of timestamps respectively corresponding to the data segments.
In the validity verification method of the present invention, in step (F), the first target segment is selected from the external data transmitted in step (E), and the first target segment has at least one timestamp selected from the external data.
In the validity verification method of the present invention, in step (G), the second target segment is selected from the external data received by the server, and the second target segment has at least one timestamp selected from the external data.
Another object of the present invention is to provide a validity verification method implemented by an electronic device, wherein the electronic device is communicatively connected to a server and continuously receives a plurality of external data around the electronic device, and the validity verification method is used for verifying the validity of the electronic device and comprises the following steps:
(A) generating a first key value according to at least one stored transmitted target section by the electronic device;

Drawings
Other features and effects of the present invention will be apparent from the embodiments with reference to the accompanying drawings, in which:
FIG. 1 is a block diagram illustrating a master-slave system that performs a preferred embodiment of the legitimacy verification method of the present invention; and
FIG. 2 is a flowchart illustrating steps 50-61 of the preferred embodiment.
Detailed Description
Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same reference numerals.
Referring to fig. 1, the preferred embodiment of the validity verification method of the present invention is implemented by a master-slave system 100, wherein the master-slave system 100 includes a server 1 and an electronic device 2 communicatively connected to the server 1.
The server 1 includes a server communication module 11 connected to a communication network (not shown), a server storage module 12, and a server processing module 13 electrically connected to the server communication module 11 and the server storage module 12.
The electronic device 2 is configured to continuously receive a plurality of external data of its surroundings, the external data being time-dependent. The electronic device 2 includes an electronic communication module 21 connected to a communication network, an electronic storage module 22, an electronic input/output (I/O) module 23 for receiving the external data, and an electronic processing module 24 electrically connected to the electronic communication module 21, the electronic storage module 22 and the electronic I/O module 23. In the preferred embodiment, each external data may be, but is not limited to, sensing data, an ON/OFF signal, Counter data, etc. of the periphery of the electronic device 2.
The electronic device 2 may be disposed on various devices that need to collect external data, for example, the electronic device 2 may be disposed on a spindle or a tool magazine of a processing machine to collect external data such as temperature, vibration, volume, humidity, etc. during the use of the processing machine.
Referring to fig. 1 and 2, the preferred embodiment of the method for verifying the validity of the present invention includes the following steps.
In step 50, the electronic processing module 24 transmits a to-be-compared key pre-stored in the electronic storage module 22 to the server 1 through the electronic communication module 21.
In step 51, after receiving the key to be compared through the server communication module 11, the server processing module 13 verifies the key to be compared according to a server key stored in advance; if the key verification fails and the electronic device 2 is not a legitimate device, the process of step 52 is performed, and if the key verification succeeds, the process of step 54 is performed.
The key verification method is a known technique and is not a key point of the present invention, and therefore, the details thereof are not described herein.
In step 52, the server processing module 13 generates a failure reply and transmits the failure reply to the electronic device 2 through the server communication module 11.
In step 53, the electronic processing module 24 disables (Disable) the electronic device 2 itself after receiving the failure reply through the electronic communication module 21.
In step 54, the server processing module 13 generates a key approval reply and transmits the key approval reply to the electronic device 2 through the server communication module 11.
In step 55, the electronic processing module 24 generates a first key value according to a transmitted target segment stored in the electronic storage module 22, and transmits the first key value to the server 1 through the electronic communication module 21.
In step 56, the server processing module 13 generates a second key value according to a received target segment stored in the server storage module 11.
In step 57, after receiving the first key value through the server communication module 11, the server processing module 13 determines whether the first key value is the same as the second key value; if so, the process of step 58 is performed, otherwise, the process returns to the process of step 52, which indicates that the electronic device 2 is not a legitimate device.
In step 58, the server processing module 13 generates a transmission approval reply and replies the transmission approval reply to the electronic device 2 through the server communication module 11.
In step 59, the electronic processing module 24 transmits the external data to the server 1 after receiving the transmission approval reply through the electronic communication module 21, where the external data is continuously received by the electronic I/O module 23, and each external data includes a plurality of data segments and a plurality of timestamps (timestamps) respectively corresponding to the data segments.
In step 60, the electronic end processing module 24 generates a first target segment according to the external data transmitted in step 59, and stores the first target segment to update the transmitted target segment, and returns to step 55. The first target segment is selected from the external data transmitted in step 59, and the first target segment has at least one timestamp selected from the external data.
In step 61, after receiving the external data through the server communication module 11, the server processing module 13 generates a second target segment according to the received external data, and stores the second target segment to update the received target segment, and returns to step 56. The second target section is selected from the external data received by the server 1, and the second target section has at least one timestamp selected from the external data.
It should be noted that the electronic device 2 and the server 1 select the first target segment and the second target segment from the transmitted and received external data respectively according to the same rule, and the electronic device 2 and the server 1 also generate the first key value and the second key value according to the transmitted target segment and the received target segment respectively according to the same algorithm, for example, the same hash (hash) function.
In summary, if the electronic device 2 is replaced, the transmitted external data is asynchronous with the external data received by the server 1, and the same first key value and the same second key value cannot be calculated naturally, so that the electronic device cannot pass the verification; furthermore, if a plurality of electronic devices (not shown) are manufactured in "hard copy", the timestamp of the external data is continuously updated when any electronic device is connected to the server 1, and if the rest of the electronic devices manufactured in "hard copy" try to connect, these electronic devices are disabled, and the server 1 can further send an abnormal message for the user to know when such an abnormal condition is found. Therefore, the object of the present invention can be achieved.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
