Title:
CONTENT TRANSMISSION/RECEPTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/001877
Kind Code:
A1
Abstract:
Provided is a device capable of easily determining that an original content is different from an edited content which is moved again. A content transmission device (60) divides an edited content comprised of an original portion content and an edited portion content into a plurality of transfer data, generates a temporary number for each transfer data, encrypts the respective transfer data on the basis of the temporary numbers, transmits the encrypted transfer data and the temporary numbers, and generates non-consecutive temporary numbers when the original portion content and the edited portion content are switched. A content reception device (70) receives the encrypted transfer data and the temporary numbers, performs decryption on the basis of the received temporary numbers, writes the transfer data in a recording medium, and learns the presence of the edited portion content when a received temporary number is not consecutive from the previously received temporary number.
