Abstract
Theft of decompressed digital content as the content is being rendered is prevented. A requested slow-down of the rendering of the content is detected. Transfers of relatively large amounts of data are detected. A re-compressor-based requested slow-down of the rendering of the content is detected. A re-compressor re-compressing the content is detected. In each situation, the detected activity is presumably initiated by a content thief attempting to steal the content. In each situation, the detected activity is responded to in a manner designed to frustrate the presumed attempt of the content thief to steal the content.

15. A method of preventing theft of decompressed digital content as the content is being rendered, the method comprising:
-
detecting a re-compressor-based requested slow-down of the rendering of the content, wherein the detected requested slow-down is presumably initiated by a content thief attempting to steal and re-compress the content; and
responding to the detected requested slow-down in a manner designed to frustrate the presumed attempt of the content thief to steal and re-compress the content. - View Dependent Claims (16, 18, 19, 20, 21, 22, 23, 24, 25)

44. A computer-readable medium having computer-executable instructions thereon for preventing theft of decompressed digital content as the content is being rendered, the instructions being organized into modules including:
-
a first module for detecting a re-compressor-based requested slow-down of the rendering of the content, wherein the detected requested slow-down is presumably initiated by a content thief attempting to steal and re-compress the content; and
a second module for responding to the detected requested slow-down in a manner designed to frustrate the presumed attempt of the content thief to steal and re-compress the content. - View Dependent Claims (45, 47, 48, 49, 50, 51, 52, 53, 54)
