Abstract
Embodiments of the present systems and methods may provide data watermarking without reliance on error-tolerant fields, thereby providing for the incorporation of watermarks in data that was not considered suitable for watermarking. For example, in an embodiment, a computer-implemented method for watermarking data may comprise inserting watermark data into a field that requires format-preserving encryption.
Claims25
A computer-implemented method for watermarking data, the method comprising:
- inserting watermark data into a field that requires format-preserving encryption.
A system for watermarking data, the system comprising a processor, memory accessible by the processor, and computer program instructions stored in the memory and executable by the processor to perform:
- inserting watermark data into a field that requires format-preserving encryption.
A computer program product for watermarking data, the computer program product comprising a non-transitory computer readable storage having program instructions embodied therewith, the program instructions executable by a computer, to cause the computer to perform a method comprising:
- inserting watermark data into a field that requires format-preserving encryption.
