Multi Facial Blurring using Improved Henon Map
Abstract: Generally, full
encryption is applied on the entire image to obscure the faces. However, it
suffers in overhead, speed and time. Alternatively, selective encryption can be
used to encrypt only the sensitive part of the image such as human faces. This
paper proposes a new encryption algorithm using enhanced Henon chaotic map to
conceal the faces. This technique involves three steps: face detection,
encryption and decryption. Experiments have been performed to evaluate security
such as histogram, sensitivity and statistical analysis, and results reveal
that the proposed method provides high security with entropy and correlation
close to ideal values.
