A method for secure distribution of digital content, the method including the steps of dividing a unit of digital content into at least first and second portions, storing the first portion on a first computerized apparatus, digitally watermarking the second portion, and combining the first portion and the digitally watermarked second portion, thereby forming a watermarked version of the digital content.

A method protecting digital content by integrating the digital content with an executable software package such as a digital media player. An earlier method proposed in 2002, a patent application in which it describes digital content can be used by initiating the executable software it was encoded with, but the content itself cannot be accessed, nor can the protection mechanism be cracked.

With this software, you can create one or more "virtual disks" on your flash drive. These disks operate exactly like a normal disk, with the exception that anything written to one of them is transparently, and securely, encrypted before being stored on your computer's hard drive.

Free open-source disk encryption software for Windows 7/Vista/XP, Mac OS X, and Linux. Can be installed on flash drives.

Briefly summarized, the claimed invention includes a connection port, a microcontroller, a flash memory, and a security program for limiting access to the flash memory. The security program provides pass code security and verification of this pass code determines how data can be exchanged between a computer to which the connection port is connected and the flash memory.

Relating to secure external data transfer.
