Abstract: An information processing system includes an acquisition unit configured to acquire a first surgical record that is a record of information regarding an operation of a medical device used in surgery, a conversion unit (101) configured to perform protection processing for personal information of a patient included in the first surgical record to convert the first surgical record into a second surgical record, an identification information generation unit (102) configured to generate first identification information associated with the first surgical record and second identification information associated with the second surgical record, and a determination unit (103) configured to determine which of the first surgical record associated with the first identification information and the second surgical record associated with the second identification information is to be transmitted to a node (30) used by the user on the basis of authority information regarding an authority of the user.

Abstract: An information processing apparatus may include the following elements. A content data generating unit generates first unit data segments constituting first content data and sequentially outputs the data segments. A holding unit is divided into a first holding area and a second holding area and holds the output first unit data segments in the first area. A recording control unit controls a recording operation such that the data segments in the first area are recorded onto at least one of first and second recording media. When second content data is recorded on the first medium, the recording control unit may control a transfer operation in addition to the recording operation such that each second unit data segment constituting the second content data is read from the first medium, the read data segment may be held in the second area, and the held data segment may be transferred to the second medium.
