Data processing apparatus for assigning an access right to a file linked in a message
A data processing apparatus includes: a monitoring unit that monitors a message from a sender to a user group; an extraction unit that, in a case where the message includes a link to a file, extracts one or more of authorized user groups authorized to access the file; and an update unit that, in a case where the user group that has received the message includes a user who is not authorized to access the file, updates user group information to add the user to one or more of the one or more authorized user groups extracted by the extraction unit.
1. A data processing apparatus comprising:
a processor, the processor being a hardware processor that is programmed to:
monitor a message from a sender to a user group;
in a case where the message includes a link to a file, extract one or more authorized user groups authorized to access the file;
in a case where the user group that has received the message includes a user who is not authorized to access the file, update user group information to add the user to one or more of the one or more authorized user groups extracted;
determine whether there is one authorized user group or whether there are two or more authorized user groups that have been extracted;
when only one of the authorized user groups is extracted, update the user group information to add the user to the extracted one authorized user group; and
when two or more of the authorized user groups are extracted, issue a notification for prompting selection of at least one of the authorized user groups to which the user is to be added.
2. The data processing apparatus according to claim 1 ,
wherein, the processor is programmed to further notify levels of relevance between the extracted two or more authorized user groups and the user.
3. The data processing apparatus according to claim 2 ,
wherein an authorized user group that includes more members of the user group is considered to have a higher level of relevance to the user.
4. The data processing apparatus according to claim 3 ,
wherein the processor is programmed to issue the notification to the sender of the message.
5. The data processing apparatus according to claim 3 ,
wherein the processor is programmed to issue the notification to at least one member of the user group that has received the message.
6. The data processing apparatus according to claim 3 ,
wherein the processor is programmed to issue the notification to an administrator of the user group that has received the message.
7. The data processing apparatus according to claim 2 ,
wherein the processor is programmed to issue the notification to the sender of the message.
8. The data processing apparatus according to claim 2 ,
wherein the processor is programmed to issue the notification to at least one member of the user group that has received the message.
9. The data processing apparatus according to claim 2 ,
wherein the processor is programmed to issue the notification to an administrator of the user group that has received the message.
10. The data processing apparatus according to claim 1 ,
wherein the notification is issued to the sender of the message.
11. The data processing apparatus according to claim 1 ,
wherein the processor is programmed to issue the notification to at least one member of the user group that has received the message.
12. The data processing apparatus according to claim 1 ,
wherein the processor is programmed to issue the notification to an administrator of the user group that has received the message.
13. The data processing apparatus according to claim 1 ,
wherein the notification for prompting selection of the at least one of the authorized user groups includes a list of the authorized user groups.
14. The data processing apparatus according to claim 13 ,
wherein the processor is programmed to sort the authorized user groups in the list in descending order of a number of participants in each user group of recipients of the message.
