Digitally Lending Content Without Reproduction

摘要

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.

主权项

1. A method of transferring data, comprising:
reading first data stored in a first non-volatile storage medium from the first non-volatile storage medium to a first volatile memory; transmitting corresponding data from the first volatile memory to a second volatile memory, wherein the corresponding data is configured to be stored in a second non-volatile storage medium; after the corresponding data is read from the first non-volatile storage medium to the first volatile memory, or after the corresponding data is transmitted to the second volatile memory, erasing at least a portion of the first data from the first non-volatile storage medium; and after the corresponding data is transmitted to the second volatile memory, or after the corresponding data is stored in the second non-volatile storage medium, erasing the first data from the first volatile memory; wherein the corresponding data is erased from the second volatile memory after the corresponding data is stored in the second non-volatile storage medium, and wherein 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.
