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.

Claims17

Dependent claims

A method of anonymizing users of an online service, comprising:

at a server system:
receiving log-in information from a user, wherein the login information includes a unique identifier that is indicative of the user's identity;
generating, for the user, a dynamic identifier for an activity group of which the user is a member, wherein the activity group includes a plurality of users other than the user;
storing the dynamic identifier as a randomly generated key value for the unique identifier;
receiving an operation instruction from the user, the operation instruction including the unique identifier and a request to perform an operation within the activity group;
using the unique identifier, identifying, among a plurality of pre-stored randomly generated key values, a randomly generated key value as the dynamic identifier for the user;
hiding the identity of the user from whom respective operation instructions are received by:
sending, to the plurality of users of the activity group, the operation instruction for execution of the operation by the plurality of users, wherein the user is identified to the plurality of users only by the dynamic identifier and not the unique identifier for the user;
and
after a time period has elapsed since the generating operation, while the user is still in the activity group, re-generating a new dynamic identifier for the user from which to send subsequent operation instructions for execution of the operation by the plurality of users in replacement of the previously-generated dynamic identifier.

7 more elements

A server system, comprising:

one or more processors;
and
memory storing one or more programs, wherein the one or more programs are configured to be executed by the one or more processors, the one or more programs including instructions for:
receiving log-in information from a user, wherein the login information includes a unique identifier that is indicative of the user's identity;
generating, for the user, a dynamic identifier for an activity group of which the user is a member, wherein the activity group includes a plurality of users other than the user;
storing the dynamic identifier as a randomly generated key value for the unique identifier;
receiving an operation instruction from the user, the operation instruction including the unique identifier and a request to perform an operation within the activity group;
using the unique identifier, identifying, among a plurality of pre-stored randomly generated key values, a randomly generated key value as the dynamic identifier for the user;
hiding the identity of the user from whom respective operation instructions are received by:
sending, to the plurality of users of the activity group, the operation instruction for execution of the operation by the plurality of users, wherein the user is identified to the plurality of users only by the dynamic identifier and not the unique identifier for the user;
and
after a time period has elapsed since the generating operation, while the user is still in the activity group, re-generating a new dynamic identifier for the user from which to send subsequent operation instructions for execution of the operation by the plurality of users in replacement of the previously-generated dynamic identifier.

9 more elements

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 system, cause the server system to:

receive log-in information from a user, wherein the login information includes a unique identifier that is indicative of the user's identity;
generate, for the user, a dynamic identifier for an activity group of which the user is a member, wherein the activity group includes a plurality of users other than the user;
store the dynamic identifier as a randomly generated key value for the unique identifier;
receive an operation instruction from the user, the operation instruction including the unique identifier and a request to perform an operation within the activity group;
using the unique identifier, identifying, among a plurality of pre-stored randomly generated key values, a randomly generated key value as the dynamic identifier for the user;
hide the identity of the user from whom respective operation instructions are received by:
sending, to the plurality of users of the activity group, the operation instruction for execution of the operation by the plurality of users, wherein the user is identified to the plurality of users only by the dynamic identifier and not the unique identifier for the user;
and
after a time period has elapsed since the generating operation, while the user is still in the activity group, re-generating a new dynamic identifier for the user from which to send subsequent operation instructions for execution of the operation by the plurality of users in replacement of the previously-generated dynamic identifier.
