Abstract: A method and system of computer-automated detection of personally identifiable (PI) data in electronic data are provided. The method includes: receiving the electronic data including the PI data and transmitting the electronic data to a modifiable hash algorithm in a first computing environment. The method further includes generating, by the modifiable hash algorithm, hashed electronic data via masking the PI data; comparing, by a PI detector service function algorithm in a second computing environment, first electronic data fields of the received electronic data including the PI data with second electronic data fields of the hashed electronic data including the masked PI data in order to detect a match indicating a presence of unmasked PI data between the first and second electronic data fields; generating, by the PI detector service function algorithm, a result with a confidence level based on the comparison; and outputting the result with the confidence level.
