Abstract
An information processing device includes: a receiving operation for receiving, from a transmission device, content and first verification data corresponding to divided content obtained by dividing the content; a detecting operation for detecting an error of the divided content based on second verification data to be calculated based on the divided content and the first verification data received in the receiving operation; and an obtaining operation for obtaining other divided content corresponding to the divided content having the error detected in the detecting operation from another information processing device different from the transmission device, when the error of the divided content is detected in the detecting operation.
Claims13
A non-transitory machine readable medium in which a program causing an information processing device to process content transmitted by a transmission device is recorded, the program causing the information processing device to execute:
- a receiving operation which receives, from the transmission device, divided content, specific information for specifying the divided content, and first verification data corresponding to the divided content;
- a detecting operation which detects an error of the divided content by comparing the first verification data received in the receiving operation and second verification data that is calculated based on the divided content received in the receiving operation and the specific information received in the receiving operation;
- and
- an obtaining operation which obtains divided content specified by the specific information from another information processing device different from the transmission device, when the error of the divided content is detected in the detecting operation.
An information processing device which processes content transmitted from a transmission device, the information processing device comprising:
- a processor configured to
- receive divided content, specific information for specifying the divided content and first verification data corresponding to the divided content from the transmission device;
- detect an error of the divided content by comparing the received first verification data and second verification data that is calculated based on the received divided content and the received specific information;
- and
- obtain divided content specified by the specific information from another information processing device different from the transmission device, when the error of the divided content is detected.
A content processing method for processing content transmitted from a transmission device to an information processing device, the method comprising:
- receiving, by the processing device, divided content, specific information for specifying the divided content and first verification data corresponding to the divided content from the transmission device;
- detecting an error of the divided content by comparing the received first verification data and second verification data that is calculated based on the received divided content and the received specific information;
- and
- obtaining divided content specified by the specific information from another information processing device different from the transmission device, when the error of the divided content is detected.
A content processing system comprising:
- a transmission device;
- and
- an information processing device which processes content transmitted from the transmission device, the information processing device configured to
- receive divided content, specific information for specifying the divided content, and first verification data corresponding to the divided content from the transmission device;
- detect an error of the divided content by comparing the received first verification data and second verification data that is calculated based on the received divided content and the received specific information;
- and
- obtain divided content specified by the specific information from another information processing device different from the transmission device, when the error of the divided content is detected.
