1. A system for identifying potentially sensitive information, comprising:
a collection system that receives data including potentially sensitive information;
an approved scanning vendor with a scanning device that communicates with the collection system and programmed to:
scan the collection system to identify any potentially sensitive data strings, each potentially sensitive data string comprising a series of consecutive digits having a same length or a same range of lengths as a complete length or a complete range of lengths of sensitive data of interest in which each digit of the series of consecutive digits is a decimal number;
sequentially and individually evaluate a subseries of consecutive digits at a beginning of the series of consecutive digits of each potentially sensitive data string to determine whether the subseries of consecutive digits corresponds to a known identifier of the sensitive data of interest;
compare a first value of a first digit of the subseries of consecutive digits to a group consisting of known values of first digits of a plurality of identifiers of the sensitive data of interest and
if the first value of the first digit does not correspond to a first known value of a first digit of a bank identification number, terminate evaluation of the series of consecutive digits; or
if the first value of the first digit matches a known value of first digits of the plurality of identifiers of the sensitive data of interest, compare a second value of a second digit of the subseries of consecutive digits to a group consisting of values of second digits known to correspond to the first value of the first digit in a plurality of identifiers of the sensitive data of interest.
