Operating a match cooperative without handling personally identifiable information

A non-transitory computer-readable medium including stored thereon a sequence of instructions which, when executed by a processor causes the processor to execute a process, the process comprising:

• transmitting obfuscation code configured to be embedded in a plurality of webpages and to generate an obfuscated representation of personal identifiable information, wherein each webpage of the plurality of webpages is configured to execute the obfuscation code embedded into the webpage upon detection of one or more predetermined events;
• receiving a first electronic message, the first electronic message comprising first cookie data having been generated as a result of user interaction with a first webpage of the plurality of webpages, the first cookie data including at least one first obfuscated representation of personally identifiable information having been generated from the obfuscation code embedded in the first webpage and at least one first identifiable user attribute comprising non-personally identifiable information;
• receiving a second electronic message, the second electronic message comprising second cookie data having been generated as a result of user interaction with a second webpage of the plurality of webpages, the second cookie data including at least one second obfuscated representation of personally identifiable information having been generated from the obfuscation code embedded in the second webpage and at least one second identifiable user attribute comprising non-personally identifiable information;
• determining an equivalence between the first cookie data and the second cookie data by probabilistic matching of the at least one first obfuscated representation of personally identifiable information and the at least one second obfuscated representation of personally identifiable information, the equivalence indicating that the first cookie data and the second cookie data are associated with a same user;
• generating shared cookie data that includes the at least one first identifiable user attribute and the at least one second identifiable user attribute;
• and
• transmitting the shared cookie data to a first device associated with the first electronic message and to a second device associated with the second electronic message.

A system comprising:

• a processor;
• a non-transitory computer-readable medium including stored thereon a sequence of instructions which, when executed by a processor causes the processor to execute a process, the process comprising:
• transmitting obfuscation code configured to be embedded in a plurality of webpages and to generate an obfuscated representation of personal identifiable information, wherein each webpage of the plurality of webpages is configured to execute the obfuscation code embedded into the webpage upon detection of one or more predetermined events;

• receiving a second electronic message, the second electronic message comprising second cookie data having been generated as a result of user interaction with a second webpage of the plurality of webpages, the second cookie data including at least one second obfuscated representation of personally identifiable information having been generated from the obfuscation code embedded in the second webpage and at least one second identifiable user attribute comprising non-personally identifiable information;
• determining an equivalence between the first cookie data and the second cookie data by probabilistic matching of the at least one first obfuscated representation of personally identifiable information and the at least one second obfuscated representation of personally identifiable information, the equivalence indicating that the first cookie data and the second cookie data are associated with a same user;
• generating shared cookie data that includes the at least one first identifiable user attribute and the at least one second identifiable user attribute;
• and
• transmitting the shared cookie data to a first device associated with the first electronic message and to a second device associated with the second electronic message.
