Abstract

A method for reading a portable data storage device for a playback platform, including setting a platform application program on the playback platform, and setting a first read instruction file and a second read instruction file inside the portable data storage device , generate a composite connection file from a series of garbled characters and encrypted digital data, and write the composite connection file into the first read instruction file, so that the digital data must be read through the second read instruction file, and when the platform application When judging that the series of data conform to the agreement defined by both parties, the platform application program uses the encryption key generated by the composite connection file to decrypt the relevant data, so as to obtain the identification ID or the digital data.

Description

technical field [0001] The invention relates to a method for a playback platform to read a portable data storage device, especially a measure for protecting digital data. Background technique [0002] Due to the progress of computer and digital technology, the content of many creations and writings (such as movies or music content) has been converted into digital audio-visual compression files, and then the files are burned on audio-visual carriers such as CDs and DVDs for general use. consumer use. The content of the creation and writing, in addition to movies or music, even widely extends to lectures, teaching videos, stage plays, etc., all of which can be converted into digital audio-visual compressed files (hereinafter collectively referred to as "digital data"). [0003] However, due to the proficiency of compression and duplication technology, the aforementioned digital data, whether movies or music content, are easily formed into various file formats and reproduced t...
