Abstract
Baseline JPEG is not well suited for designing efficient encryption schemes. Selective encryption technology can be applied much better to visual data in scalable representation. We use the three progressive modes as defined in the JPEG extended system for providing confidentiality to visual data by encrypting selected scans. Whereas the hierarchical progressive and spectral selection modes turn out to be highly insecure when encryption effort is decreased, reasonable security can be maintained using successive approximation
