Data verification method, information processing apparatus, consumable, and image-forming apparatus

An information processing apparatus, wherein the information processing apparatus is capable of communicating with an image-forming apparatus, the image forming apparatus being detachably installed with a consumable, comprising:

• a first receiving module, configured to receive a verification request sent by the image-forming apparatus;
• a first output module, configured to send original data and target verification information to the image-forming apparatus based on the verification request, wherein at least partial data in the target verification information is configured to verify the original data;
• a second output module, configured to send the first calculation factor to the image-forming apparatus based on the verification request;
• a second receiving module, configured to receive first intermediate data generated based on the first calculation factor and sent by the image-forming apparatus;
• and
• a generating module, configured to generate the target verification information based on the first intermediate data, wherein a data length of the target verification information is shorter than a data length of first verification information generated based on the original data according to a preset first algorithm.
