Corrupted sensors detection in sensor consortium

A computer system, comprising:

• a memory storing one or more programs;
• and
• one or more processors, configured to execute the one or more programs to perform operations comprising:
• identifying one or more correlating sensors to a first sensor;
• dynamically determining correlation between the first sensor and the correlating sensors according to historical sensor values using an inter sensor correlation model, wherein each of the correlating sensors have a different level of correlation with the first sensor;
• obtaining a calculated value of the first sensor based on values of the correlating sensors and the correlation;
• obtaining a measured value of the first sensor;
• determining a difference between the calculated value and the measured value of the first sensor is greater than and/or equal to a threshold value;
• when the difference between the calculated value and the measured value of the first sensor is greater than and/or equal to the threshold value, checking a working condition of each of the correlating sensors;
• determining whether the first sensor is corrupted based on the working condition of each of the correlating sensors;
• and
• updating one of a firmware or software of the first sensor upon determining that the first sensor is corrupted.

A non-transitory computer readable medium, saving one or more programs, the one or more programs, when executed by one or more processors, causing a computer system to perform steps comprising:
