Abstract
A method and apparatus for watermarking sensed data in a sensing device which senses a subject to obtain sensed data includes the sensing device temporarily storing the sensed data. The sensing device collects metadata associated with a user of the sensing device and temporarily stores the metadata. The sensing device generates watermarked data by watermarking the sensed data with the metadata.
