- •
By studying the resources constraints with their development trends in video sensing system, an information-utility-value-oriented multimedia encryption optimization model under resources constraints is given.
- •
A video-compression-independent speed-adjustable lightweight encryption scheme with its improved version based on the previously proposed model is given.
- •
A DSP and ARM based embedded secure video sensing system is designed, and the proposed encryption scheme has been implemented in it.
