Abstract
In accordance with an aspect of the invention, a method and system are disclosed for constructing an embedded signature in order to facilitate post-facto detection of leakage of sensitive data. The leakage detection mechanism involves: 1) identifying at least one set of words in an electronic document containing sensitive data, the set of words having a low frequency of occurrence in a first collection of electronic documents; and, 2) transmitting a query to search a second collection of electronic documents for any electronic document that contains the set of words having a low frequency of occurrence. This leakage detection mechanism has at least the following advantages: a) it is tamper-resistant; b) it avoids the need to add a watermark to the sensitive data, c) it can be used to locate the sensitive data even if the leakage occurred before the embedded signature was ever identified; and, d) it can be used to detect an embedded signature regardless of whether the data is being presented statically or dynamically.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
