Abstract
Example methods and apparatus to de-duplicate impression information. An example method includes accessing a first set of cookies and a set of user identifiers, the cookies and user identifiers corresponding to devices accessing media via the Internet, identifying a pattern in the first set of cookies, obtaining impression information from a database proprietor, the impression information comprising a second set of cookies, identifying a subset of the second set of cookies that are associated with a same person based on the pattern, and associating impressions corresponding to the identified subset with the same person.
Claims21
A method, comprising:
- accessing, by executing a first instruction with a processor, a first set of cookies and a set of user identifiers received via the Internet and stored in a storage device, the cookies and the user identifiers corresponding to devices accessing media via the Internet;
- identifying, by executing second instructions with the processor, a pattern in the first set of cookies by:
- identifying a potential pattern in the first set of cookies;
- determining a first error between a first demographic estimate based on the potential pattern in the first set of cookies and a second demographic estimate based on the user identifiers;
- and
- when the first error is less than a threshold, determining the potential pattern to be the pattern;
- obtaining, at the processor, impression information from a database proprietor via the Internet, the impression information including a second set of cookies;
- identifying, by executing a third instruction with the processor, a subset of the second set of cookies that are associated with a same person based on the pattern;
- and
- associating, by executing a fourth instruction with the processor, impressions corresponding to the identified subset with the same person.

A method, comprising:
- accessing, by executing a first instruction with a processor, a first set of cookies and a set of user identifiers received via the Internet and stored in a storage device, the cookies and the user identifiers corresponding to respective devices accessing media via the Internet;
- identifying, by executing a second instruction with the processor, a pattern in the first set of cookies, identifying the pattern including iteratively determining an error based on patterns identified from different portions of data payloads of the cookies;
- obtaining, at the processor, impression information from a database proprietor, the impression information including a second set of cookies;
- identifying, by executing a third instruction with the processor, a subset of the second set of cookies that are associated with a same person based on the pattern;
- and
- associating, by executing a fourth instruction with the processor, impressions corresponding to the identified subset with the same person.
3 more elements
An apparatus, comprising:
- a cookie pattern identifier to access a first set of cookies and a set of user identifiers and to identify a pattern in the first set of cookies, the cookies and the user identifiers being received via the Internet and stored in a storage device and corresponding to devices accessing media via the Internet;
- a pattern evaluator to determine a first error between a first demographic estimate based on a potential pattern in the first set of cookies and a second demographic estimate based on the user identifiers, the cookie pattern identifier to identify the potential pattern in the first set of cookies and, when the first error is less than a threshold, determine the potential pattern to be the pattern;
- an impression collector to access impression information received from a database proprietor via the Internet, the impression information including a second set of cookies;
- and
- an impression de-duplicator to identify a subset of the second set of cookies that are associated with a same person based on the pattern, and associate impressions corresponding to the identified subset with the same person, at least one of the cookie pattern identifier, the pattern evaluator, the impression collector, or the impression de-duplicator being implemented with a processor.

An apparatus, comprising:
- a cookie pattern identifier to access a first set of cookies and a set of user identifiers received via the Internet and stored in a storage device and to identify a pattern in the first set of cookies by iteratively determining an error based on patterns identified from different portions of data payloads of the cookies, the cookies and the user identifiers corresponding to devices accessing media via the Internet;
- an impression collector to access impression information received from a database proprietor via the Internet, the impression information including a second set of cookies;
- and
- an impression de-duplicator to identify a subset of the second set of cookies that are associated with a same person based on the pattern, and associate impressions corresponding to the identified subset with the same person, at least one of the cookie pattern identifier, the impression collector, or the impression de-duplicator being implemented with a processor.
1 more element
A tangible computer readable storage device comprising computer readable instructions which, when executed, cause a processor to at least:
- access a first set of cookies and a set of user identifiers received via the Internet and stored in a second storage device, the cookies and the user identifiers corresponding to accessing media via the Internet;
- identify a pattern in the first set of cookies by:
- identifying a potential pattern in the first set of cookies;
- determining a first error between a first demographic estimate based on the potential pattern in the first set of cookies and a second demographic estimate based on the user identifiers;
- and
- when the first error is less than a threshold, determining the potential pattern to be the pattern;
- access impression information from a database proprietor received via the Internet, the impression information including a second set of cookies;
- identify a subset of the second set of cookies that are associated with a same person based on the pattern;
- and associate impressions corresponding to the subset with the same person.

- access a first set of cookies and a set of user identifiers received via the Internet and stored in a second storage device, the cookies and the user identifiers corresponding to accessing media via the Internet;
- identify a pattern in the first set of cookies by iteratively determining an error based on patterns identified from portions of a data payload of the cookies;
- access impression information from a database proprietor received via the Internet, the impression information including a second set of cookies;
- identify a subset of the second set of cookies that are associated with a same person based on the pattern;
- and associate impressions corresponding to the subset with the same person.
