Abstract

The invention relates to a device and a relevant method that adapts to any type of storage media, and to protect digital contents and universal playing with an encryption / deciphering engine. The device is characterized as follows: A device communication interface, is used to connect the device with other external devices, and undertakes data transmission between them; a device controller, comprises an encryption / deciphering engine that have been widely verified and have high security, and moreover, a distinct identifier; the encryption / deciphering engine uses the distinct identifier as a key, in order to perform encryption operation for digital contents; as well as large quantity of storage media, comprise encryption data areas to stores digital contents after encryption; moreover, perform deciphering action for the encrypted digital contents that are stored through identifying the distinct identifier. The invention also relates to a software application programming interface (API) and a relevant method, so that the storage device can be universally used in personal computers / laptop computers, embedded systems as well as portable host computer devices.

Description

technical field [0001] The invention relates to a device and method for protecting digital content and universal playback by using an encryption / decryption engine on any storage device. Background technique [0002] In recent years, due to the vigorous development of various multimedia, a variety of digital contents, such as music, pictures, files, movies, etc., are naturally derived. With the evolution of technology, the capacity occupied by the above-mentioned digital content is also increasing day by day, so the media capacity used to store these digital contents is also increasing day by day, and when the storage capacity grows to a certain level, the portable storage system begins to develop. Media, from the earliest 1.2MB disk to the current USB flash drive, external hard disk, CD, etc., have not only improved the speed of information circulation, but also improved the convenience of data backup and storage. [0003] However, while information backup is easy and the c...
