Patent ID: 10949645

Abstract:
A data verification method is provided. Fingerprint information of N (N being an integer greater than 1) slices of to-be-sent data of a second device is received, the fingerprint information including first fingerprint information corresponding to an ith (i being an integer greater than 1) slice of the to-be-sent data and second fingerprint information corresponding to an (i−1)th slice of the to-be-sent data. The first fingerprint information is based on updating, by using the ith slice of the to-be-sent data, the second fingerprint information. An ith slice of data is received from the second device. The received second fingerprint information is updated by using the ith slice of data, to obtain third fingerprint information. Data verification failure indication information is transmitted to the second device in response to the third fingerprint information not matching the received first fingerprint information.
