Data file verification method and device

Abstract

The invention discloses a data file verification method and device, belonging to the technical field of data processing. The method includes: generating a first check code of the key data based on the key data in the data file; and verifying the key data according to the first check code and the pre-stored second check code of the key data ; If the verification of the key data is passed, it is determined that the verification of the data file is passed; if the verification of the key data is not passed, it is determined that the verification of the data file is not passed. The invention realizes the verification of the data file by verifying the key data in the data file, avoids the system-level recovery operation of the electronic device caused by the error of the non-key data in the data file, and improves the electronic device verification. The fault tolerance rate is high, and the calculation resources consumed by the electronic equipment to generate the verification code based on the key data are small, which improves the efficiency of the electronic equipment system to load and verify data files.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data file verification method and device. Background technique [0002] During the use of electronic equipment, unexpected shutdowns may occur, resulting in some data in the system of the electronic equipment not being saved normally, and the electronic equipment will often verify the data files by default when starting up and loading data files next time . Among them, the data file is used to store the data required for the system operation of the electronic device. Some data can be the data set by the user during the system operation. Taking TV as an example, this certain data can be used for the user to set the picture quality. data. [0003] In related technologies, electronic devices often perform overall verification on data files, that is, verify all contents of the data files. Specifically, the electronic device will generate a new check code based on the ent...

Problems solved by technology

[0005] In related technologies, the electronic device performs verification based on the entire data file to determine whether the data file has passed the verification. Since the entire data file has a lot of content, generating a verification code based on the entire data file needs to consume more computing resources. The data file It takes a long time to load and verify the data file, and once any data in the data file is wrong, the electronic device will determine that the data file has failed the verification, and then perform the corresponding recovery operation

This strict overall verification reduces the fault tolerance of system operation and the efficiency of system loading and verifying data files
