Abstract
A media data decryption method includes: obtaining a media data encryption package, wherein the media data encryption package is obtained by performing pixel rearrangement encryption on original media data based on position index data, and the position index data correspond to one or more structural parameters of a display screen; decrypting the media data encryption package to obtain the position rearrangement index data and media data to be decrypted; configuring a programmable logic circuit of a control system of the display screen in a media data play terminal based on the position rearrangement index data; and decrypting the media data to be decrypted based on the configured programmable logic circuit to obtain decrypted media data.
Claims12
A media data decryption method, comprising:
- obtaining a media data encryption package, wherein the media data encryption package is obtained by performing pixel rearrangement encryption on original media data based on position index data, and the position index data correspond to one or more structural parameters of a display screen in a media data play terminal;
- decrypting the media data encryption package to obtain position rearrangement index data and media data to be decrypted;
- configuring a programmable logic circuit of a control system of the display screen in the media data play terminal based on the position rearrangement index data;
- and
- decrypting the media data to be decrypted based on the configured programmable logic circuit to obtain decrypted media data.
A computer device comprising a memory and one or more processors, wherein the memory stores computer readable instructions, which when executed by the one or more processors, causes the one or more processors to perform following operations:
- obtaining a media data encryption package, wherein the media data encryption package is obtained by performing pixel rearrangement encryption on original media data based on position index data, and the position index data correspond to one or more structural parameters of a display screen in a media data play terminal;
- decrypting the media data encryption package to obtain position rearrangement index data and media data to be decrypted;
- configuring a programmable logic circuit of a control system of the display screen in the media data play terminal based on the position rearrangement index data;
- and
- decrypting the media data to be decrypted based on the configured programmable logic circuit to obtain decrypted media data.
