2. The method of claim 1, wherein obtaining a plurality of first parameters of the device and generating a first string based on the plurality of first parameters comprises:
combining a plurality of first parameters to obtain combined parameters;
and processing the combined parameters into a character string with a first preset length through a first abstract algorithm to obtain the first character string.
3. The method of claim 1, wherein obtaining a plurality of second parameters of the device and generating a second string based on the plurality of second parameters comprises:
combining a plurality of second parameters to obtain combined parameters;
and processing the combined parameters into a character string with a second preset length through a second abstract algorithm to obtain the second character string.
4. The method of claim 1, wherein generating a third string based on the first string and the second string comprises:
and splicing the first character string and the second character string to obtain the third character string.
5. The method of claim 1, wherein generating a third string based on the first string and the second string comprises:
splicing the first character string and the second character string to obtain a spliced character string:
and encrypting the spliced character string to obtain the third character string.
6. The method of claim 1, wherein generating a third string based on the first string and the second string comprises:
and processing the first character string and the second character string by adopting a third abstract algorithm to obtain a third character string.
7. The method of claim 1, wherein the value of the first parameter changes in the event of a system upgrade of the device.
8. Method according to claim 1, characterized in that the value of the second parameter is changed in case of a system restart of the device.
9. The method of claim 1, wherein the first parameter comprises at least one of: a system version of the device, hardware information of the device, appearance information of the device, a target service file creation update time of the device, and a system capacity of the device.
