Claim:
1. A method, comprising: receiving, at a collection facility, a first number and a first Internet address identifier, the first number generated with a first random number generator using a first seed value during a first browsing session associated with a browser, the first Internet address identifier corresponding to media that was accessed during the first browsing session; comparing, by executing an instruction with a processor at the collection facility, the first number to a sequence of numbers generated by a second random number generator, different than the first random number generator, using the first seed value; generating a lookup table, by executing an instruction with the processor at the collection facility, having the first seed value associated with the generated sequence of numbers; when the first number is in the sequence of numbers, associating, by executing an instruction with the processor at the collection facility, the first Internet address identifier with the first browsing session; receiving a second number and a second Internet address identifier; querying the lookup table, by executing an instruction with the processor, to determine whether the second number is in the sequence of numbers; and when the second number is in the sequence of numbers, storing the second address identifier, by executing an instruction with the processor at the collection facility, in connection with the first seed value in a database, wherein an entry of the database including the first address identifier and the second address identifier indicates that the first address identifier and the second address identifier were accessed during the first browsing session.
