Content is lent, or temporarily transferred, without reproduction, by reading first data stored in a first non-volatile storage medium from the first non-volatile storage medium to a first volatile memory, and transmitting corresponding data from the first volatile memory to a second volatile memory. After the reading or transmitting, at least a portion of the first data is erased from the first non-volatile storage medium. The data and corresponding data are also erased from the first volatile memory and second volatile memory and are thus stored in volatile memory for a period of not more than transitory duration. The portion of the first data stored in the first non-volatile storage medium and the corresponding data stored in the second non-volatile storage medium are not concurrently stored. In some embodiments, the first data includes one or more respective keys, each key for decrypting a respective encrypted data chunk.
