Method for processing video in TF card

Abstract

The invention discloses a method for processing a video in a TF card, which comprises the following steps of: splitting the video: splitting a complete video file in the TF card into a plurality of block files; video encryption: encrypting all the block files, and generating a loading sequence list; and video decryption: inserting the TF card into a playing device, obtaining the encryption key file in the TF card, and then decrypting and playing all the block files according to the loading sequence list. According to the method, a set of video data encryption and program protection solution which is high in pertinence, multiple in limiting condition, difficult to copy and crack and rapid in application is formed by combining the standard TF card with the running data generated in the running container of the CPU, the memory, the hard disk, the network card and the software program of the tablet computer, so that data information of a company is protected.

Description

technical field [0001] The invention relates to the field of data encryption and program protection of mobile electronic equipment, in particular to a method for processing video in a TF card. Background technique [0002] Video courseware and video players are widely used in education and training systems, audio-visual media platforms, advertising and other fields. At present, the encryption protection methods in this field are mostly encrypted by software algorithms through specified methods, and then analyzed and played by specified players. Or after encrypting through the USB-Shield, check the correctness through the specified SDK and then analyze and play it through the specified player. Although the above solution can solve the problem of data encryption and program protection, because the USB-Shield is mostly used for PCs, mobile devices There is no standard USB interface, so data security can only be completed by software solutions. With the development of network se...

[0002] Video courseware and video players are widely used in education and training systems, audio-visual media platforms, advertising and other fields. At present, the encryption protection methods in this field are mostly encrypted by software algorithms through specified methods, and then analyzed and played by specified players. Or after encrypting through the USB-Shield, check the correctness through the specified SDK and then analyze and play it through the specified player. Although the above solution can solve the problem of data encryption and program protection, because the USB-Shield is mostly used for PCs, mobile devices There is no standard USB interface, so data security can only be completed by software solutions. With the development of network security and information security, the above-mentioned methods have more and more problems and restrictions, and they are easy to bypass through technical means.
