Abstract

A method at a server system includes: grouping multiple users into an activity group, where each user has a unique identifier across different activity groups; generating, for each user of the activity group, a dynamic identifier within the activity group and a mapping between the dynamic identifier and the user'"'"'s corresponding unique identifier, where the dynamic identifier may identify different users within different activity groups; receiving an operation instruction from a first user of the activity group, the operation instruction including a first unique identifier associated with the first user; identifying a first dynamic identifier associated with the first user within the activity group based on the first unique identifier associated with the first user; associating with the operation instruction the first dynamic identifier associated with the first user within the activity group; and sending the operation instruction and the first dynamic identifier to the users of the activity group.

Claims

1. A method, comprising:

at a server system;

grouping a plurality of users into an activity group, wherein each user has a unique identifier across different activity groups;

generating, for each user of the plurality of users of the activity group, a dynamic identifier within the activity group and a mapping between the dynamic identifier and the user'"'"'s corresponding unique identifier, wherein the dynamic identifier may identify different users within different activity groups;

receiving an operation instruction from a first user of the plurality of users of the activity group, the operation instruction including a first unique identifier associated with the first user;

identifying a first dynamic identifier associated with the first user within the activity group based on the first unique identifier associated with the first user;

associating with the operation instruction the first dynamic identifier associated with the first user within the activity group; and

sending the operation instruction and the first dynamic identifier to the plurality of users of the activity group.

2. The method of claim 1, further comprising:

after a time period has elapsed since generating a respective dynamic identifier for a respective user of the plurality of users of the activity group, generating a new dynamic identifier for the respective user.

3. The method of claim 2, wherein generating a new dynamic identifier for the respective user includes:

rotating a previously generated dynamic identifier associated with another user of the plurality of users of the activity group to the respective user.

4. The method of claim 2, wherein generating a new dynamic identifier for the respective user includes:

randomly generating a new dynamic identifier for the respective user.

5. The method of claim 2, wherein a length of the time period is predefined.

6. The method of claim 2, wherein a length of the time period is random.

7. The method of claim 2, wherein the time period is synchronized across the plurality of users of the activity group.

8. A server, comprising:

memory;

one or more processors; and

one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for;

grouping a plurality of users into an activity group, wherein each user has a unique identifier across different activity groups;

generating, for each user of the plurality of users of the activity group, a dynamic identifier within the activity group and a mapping between the dynamic identifier and the user'"'"'s corresponding unique identifier, wherein the dynamic identifier may identify different users within different activity groups;

receiving an operation instruction from a first user of the plurality of users of the activity group, the operation instruction including a first unique identifier associated with the first user;

identifying a first dynamic identifier associated with the first user within the activity group based on the first unique identifier associated with the first user;

associating with the operation instruction the first dynamic identifier associated with the first user within the activity group; and

sending the operation instruction and the first dynamic identifier to the plurality of users of the activity group.

9. The server of claim 8, wherein the one or more programs further include instructions for:

after a time period has elapsed since generating a respective dynamic identifier for a respective user of the plurality of users of the activity group, generating a new dynamic identifier for the respective user.

10. The server of claim 9, wherein the instruction for generating a new dynamic identifier for the respective user includes instructions for:

rotating a previously generated dynamic identifier associated with another user of the plurality of users of the activity group to the respective user.

11. The server of claim 9, wherein the instruction for generating a new dynamic identifier for the respective user includes instructions for:

randomly generating a new dynamic identifier for the respective user.

12. The server of claim 9, wherein a length of the time period is predefined.

13. The server of claim 9, wherein a length of the time period is random.

14. The server of claim 9, wherein the time period is synchronized across the plurality of users of the activity group.

15. A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by a server, cause the server to:

group a plurality of users into an activity group, wherein each user has a unique identifier across different activity groups;

generate, for each user of the plurality of users of the activity group, a dynamic identifier within the activity group and a mapping between the dynamic identifier and the user'"'"'s corresponding unique identifier, wherein the dynamic identifier may identify different users within different activity groups;

receive an operation instruction from a first user of the plurality of users of the activity group, the operation instruction including a first unique identifier associated with the first user;

identify a first dynamic identifier associated with the first user within the activity group based on the first unique identifier associated with the first user;

associate with the operation instruction the first dynamic identifier associated with the first user within the activity group; and

send the operation instruction and the first dynamic identifier to the plurality of users of the activity group.

16. The non-transitory computer readable storage medium of claim 15, wherein the one or more programs further include instructions for:

after a time period has elapsed since generating a respective dynamic identifier for a respective user of the plurality of users of the activity group, generating a new dynamic identifier for the respective user.

17. The non-transitory computer readable storage medium of claim 16, wherein the instruction for generating a new dynamic identifier for the respective user includes instructions for:

rotating a previously generated dynamic identifier associated with another user of the plurality of users of the activity group to the respective user.

18. The non-transitory computer readable storage medium of claim 16, wherein the instruction for generating a new dynamic identifier for the respective user includes instructions for:

randomly generating a new dynamic identifier for the respective user.

19. The non-transitory computer readable storage medium of claim 16, wherein a length of the time period is random.

20. The non-transitory computer readable storage medium of claim 16, wherein the time period is synchronized across the plurality of users of the activity group.
