Embodiment 1

[0045] Embodiments of the present invention provide a method for detecting video integrity, such as figure 1 As shown, the method may include:

[0046] S101. When starting the system service, the electronic device obtains the first video file to be played and the first configuration file corresponding to the first video file, and the first configuration file includes the first MD5 (information digest algorithm 5) of the first video file , Message Digest Algorithm5) value.

[0047] Data integrity is one of the three basic points of information security, which refers to ensuring that information or data is not tampered by unauthorized or can be quickly discovered after tampering during the process of transmitting and storing information or data. In order to ensure the integrity of the data, digital signatures or hash functions are usually used to protect the ciphertext.

[0048] MD5 is a hash function widely used in the field of computer security to ensure the integrity and cons...

Embodiment 2

[0065] Embodiments of the present invention provide a method for detecting video integrity, such as figure 2 As shown, the method may include:

[0066] S201. In the power-on state, the electronic device acquires the first video file issued by the server and the first configuration file corresponding to the first video file, wherein the first configuration file includes the first MD5 value of the first video file, and the second The first MD5 value of a video file is obtained after the server calculates the video file.

[0067] Data integrity is one of the three basic points of information security. It refers to ensuring that information or data is not tampered with by unauthorized or can be quickly discovered after tampering. In order to ensure the integrity of data Security, usually using digital signatures or hash functions to protect the ciphertext.

Abstract

The embodiment of the invention provides a method and an apparatus for detecting the integrity of a video and relates to electronic technical field. The method may guarantee an electronic device to be started normally so as to enhance the system stability of the electronic device. The method comprises: acquiring a first video file to be played and a first configuration file corresponding to the first video file when system service is started, wherein the first configuration file comprises a first MD5 value of the first video file; calculating a second MD5 value of the first video file; and determining the first video file is a complete video file if the second MD5value of the first video file is the same as the first MD5 value of the first video file.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a video integrity detection method and device. Background technique [0002] With the continuous development of electronic technology, various electronic devices emerge as the times require. The use of smart electronic devices is also increasing. [0003] In the prior art, the booting process of an intelligent electronic device generally includes four stages: starting the boot program, loading the kernel program, starting the system service (the system program of the operating system) and starting the desktop program, wherein the time for the intelligent electronic device to start the system service longer. In order to effectively utilize the display resources of the smart TV during the startup process, the boot icon (logo) can be displayed when the smart TV starts the boot program and loads the kernel program, and the specified video file is played when the system service ...
