Method and system for hiding the decryption key in a dispersive way

A system of hiding the decryption key in a dispersive way, comprising:

• a memory device, storing first partial decryption key of a decryption key corresponding to content to be accessed and providing a hidden area storing second partial decryption key of the decryption key;
• and
• an electronic device, installed with an application, wherein, when the memory device is installed on the electronic device, the application is activated to retrieve the first partial decryption key from the memory device and the second partial decryption key from the hidden area of the memory device, re-organize and code the first and second partial decryption keys to recover the decryption key, and decrypt the content using the decryption key, enabling the electronic device to access the content;
• and the content with a first format is converted to the content with a second format applicable to a digital rights management (DRM) engine of the electronic device;
• the content with second format is further converted to the content with a third format by using an encryption key and an encryption program.

A non-transitory computer-readable medium encoded with computer executable instructions for performing a method of hiding the decryption key in a dispersive way, the computer executable instructions comprising:

• decomposing a decryption key corresponding to content to be accessed into at least two partial decryption keys, comprising first partial decryption key and second partial decryption key;
• converting the content with a first format to the content with a second format applicable to a digital rights management engine;
• encrypting the content with the second format using an encryption program and encryption key to convert to the content with a third format;
• storing the first partial decryption key in a memory device;
• storing the second partial decryption key in a hidden area of the memory device;
• when the memory device is installed on an electronic device, activating an application installed in the electronic device;
• the application retrieving the first partial decryption key from the memory device and the second partial decryption key from the hidden area of the memory device;
• the application re-organizing and coding the first and second partial decryption keys to recover the decryption key;
• and
• the application decrypting the content using the decryption key, enabling the electronic device to access the content.
