1. A system, comprising:

  • a communication interface for sending and receiving data;

    one or more memory elements having, stored therein, computer program code; and

    one or more processing units operatively coupled to the one or more memory elements and configured to execute instructions in the computer program code that cause the one or more processing units to;

    generate or receive two or more dynamically-changing, temporally unique identifiers;

    associate the two or more dynamically-changing, temporally unique identifiers with a first data subject;

    associate one or more data attributes with a first of the two or more dynamically-changing, temporally unique identifiers;

    generate first time period data, wherein the first time period data comprises information defining a first time period during which the first of the two or more dynamically-changing, temporally unique identifiers associated with the first data subject is used to identify the first data subject and retrieve the associated one or more data attributes;

    generate second time period data, wherein the second time period data comprises information defining a second time period during which a second one of the two or more dynamically-changing, temporally unique identifiers associated with the first data subject is used to identify the first data subject,wherein the first time period is different from the second time period,wherein the first dynamically-changing, temporally unique identifier is different from the second dynamically-changing, temporally unique identifier,wherein the first dynamically-changing, temporally unique identifier is not used to identify the first data subject during the second time period, andwherein the second dynamically-changing, temporally unique identifier is not used to identify the first data subject during the first time period, thereby providing anonymity to the first data subject;

    store, in at least one of the one or more memory elements, the two or more dynamically-changing, temporally unique identifier, the one or more data attributes, and the first and second time period data; and

    send the one or more data attributes to a first client.
