Abstract
Change fingerprinting is applied to a text file, database table, or data feed to determine the timeframe in which an identified 'wild file' was generated, even when its file creation meta-data is missing. Each row in the data contains information on a single object. At least one column in the data contains an age for each object at the time the file was created. The age data can be used to determine the date the file was created, such as by using recognition processing or by looking at data that has been added or dropped from the file based on age. By identifying the timeframe in which the wild file was created, the data owner may greatly reduce the computational burden needed to determine if the wild file contains stolen data because it greatly reduces the universe of files that must be compared to the wild file.
