1. A system comprising:
a processor; and
a computer memory on which are store instructions, comprising instructions that when executed cause the processor to:
identify a first data and a signature of the first data;
monitor requests to perform an operation on the first data made through an application programming interface;
detect, responsive to the monitoring, a first operation to be performed upon first data by the application programming interface, before the first operation is performed; and
prevent leakage of the first data by causing the application programming interface to drop the request to perform the first operation on the first data,
wherein the first operation includes transforming the first data, wherein a data signature of the first data is no longer accurate of the first data.
