Information verification method and related device

An information verification apparatus comprising:

• a processor;
• and
• a memory which is coupled to the processor and stores processor-executable instructions, wherein the processor executes the instructions causing the apparatus to:
• obtain a fluorescent signal that is an electrical signal generated based on a plurality of fluorescent spots, and the fluorescent signal comprises a plurality of pulse signals;
• determine, based on a preset amplitude threshold and an amplitude of each pulse signal, an information symbol associated with each pulse signal;
• obtain an information sequence based on the information symbol associated with corresponding to each pulse signal;
• and
• obtain a verification result of the information sequence based on a first quantity of pulse signals between any two pulse signals in the plurality of pulse signals and a time interval between the any two pulse signals.

A control device comprising at least one processor, a memory, and instructions that are stored in the memory and that can be executed by the at least one processor, and the at least one processor executes the instructions to cause the control device to:

• obtain a fluorescent signal that is an electrical signal generated based on a plurality of fluorescent spots, and the fluorescent signal comprises a plurality of pulse signals;
• determine, based on a preset amplitude threshold and an amplitude of each pulse signal, an information symbol associated with each pulse signal;
• obtain an information sequence based on the information symbol associated with each pulse signal;
• and
• obtain a verification result of the information sequence based on a first quantity of pulse signals between any two pulse signals in the plurality of pulse signals and a time interval between the any two pulse signals.
