Embodiment Construction

[0065] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0066] Such as figure 1 The scene architecture diagram or system architecture diagram of the data verification method or data sending method provided by the embodiment of the present invention is shown, and the electronic device can establish a connection with the server through the network to perform data interaction. Taking the cloud network disk as an example, the user only needs to install the corresponding client on the electronic device to transfer data files with the server that provides the cloud network disk service, including synchronously backing up data to the server, or downloading all files from the server. required data. When the electronic device backs up data to the server synchronously, the electronic device is the sender of the data, and the server is the receiver of the data; when t...

Abstract

The invention discloses a data verification method, which includes: receiving the i-th piece of data sent by the sender; wherein the sender divides the data to be sent into N pieces of data for transmission; i is greater than or equal to 1 and less than or equal to N; when i is not equal to In the case of 1, update the i-th piece of data to the pre-stored fingerprint information a to obtain the updated data; the fingerprint information a is the fingerprint information corresponding to the i-1th piece of data; calculate the fingerprint information b of the updated data, and Judging whether the fingerprint information b matches the fingerprint information c corresponding to the pre-stored i-th piece of data; if the fingerprint information b does not match the fingerprint information c, send data verification failure indication information to the sender. The invention also discloses a data sending method, a data verification device, a data sending device and a data transmission system, which solves the technical problem in the prior art that a transmission error cannot be found until the entire data file is downloaded.

Description

technical field [0001] The invention relates to the field of computers, in particular to a data checking method, a data sending method, a data receiving device, a data sending device and a data transmission system. Background technique [0002] Cloud disk or cloud network disk is an Internet storage tool. Cloud disk is the product of Internet cloud technology. It provides enterprises and individuals with services such as information storage, reading, and downloading through the Internet. It has the characteristics of safety, stability and mass storage. [0003] With the development of electronic technology and mobile Internet technology, the functions of mobile electronic devices (especially smart mobile devices) are becoming more and more powerful, and users can complete various affairs through mobile electronic devices. The current cloud network disk business can also provide cloud storage functions for file synchronization, backup and sharing functions to mobile electron...
