    Abstract: Provided are a method and apparatus for supporting a cooperative activity in which an activity is performed by cooperation among a plurality of participants, as in a television conference system. When another user attempts to participate in the cooperative activity (session), a guardian is assigned to the session and a guardian is assigned also to the user attempting to participate. Allowance or refusal of participation by the user in the session is decided based upon the access control level of the guardian corresponding to the user, a guardian tree defining the path of the guardian and the mutual relationship between the guardians.

    Abstract: The present invention relates to a group environment setting method in a system where plural participants form a group and perform a cooperative operation. Environment setting information for an application environment setting of a cooperative operation is registered in a group unit. When a group is designated by a participant, environment setting information corresponding to the designated group is read from the registered environment setting information, and applied as environment setting information of the participant. An data structure of the environment setting information has a hierarchical structure, and information related to the designated environment setting items is selected from the read environment setting information.

    Abstract: For a stored data in one file consisting of a plurality of partial data, the rewrite of each partial data by other than the regular creator is prohibited. It is aimed to permit the rewrite but determine whether or not the rewrite has been made for each partial data. Therefore, in storing the data, a first code is generated by converting a password and a predetermined portion of each partial data, for example, the partial data itself or the identification information such as a name, in a predetermined procedure, and stored in correspondence to the stored data, and in reading the stored data, a second code is generated by converting the password and said predetermined portion of the stored data in said predetermined procedure, the comparison is made between the generated second code and said first code stored in correspondence to said stored data, and the rewrite is prohibited if the comparison result is unequal, or the rewrite is determined.

    Abstract: There is provided a cooperative work supporting method and a system therefor, for smooth progress of a cooperative work by evaluating the participation rate, or the level of participation of each participant to the cooperative work, and utilizing such participation rate in the cooperative work. The cooperative work supporting method for use in a system for effecting a work by cooperation of plural participants, comprises determining a participation rate, indicating the level of participation to the cooperative work, for each participant; and informing each participant of such participation rate in identifiable manner. Also the participation of the participant to the cooperative work is adjusted according to the participation rate. Also there is provided a prompt requesting the adjustment of the participation rate of each participant. The participation rate is determined by the data read-out frequency and/or the data write-in frequency of each participant in the cooperative work. In informing, the participation rate is made identifiable by a change in the size of the number of colors of the image of each participant.

    Abstract: According to a data management method of managing shared data which is shared by a plurality of processes and data inherent in a process which exists during execution of one particular process and disappears when the process is finished, when each process fetches shared data from a data base into a memory, whether the shared data requires data inherent in the process is checked. The inherent data of the process is determined if necessity for the data is determined. The determined inherent data of the process is stored in the memory. A pointer for the inherent data of the process, which is stored in the memory, is stored into the fetched shared data in accordance with attributes inherent in the process requiring the inherent data of the process.
