  Facebook is the online social networks (OSNs) platform with the largest
number of users in the world today, information protection based on Facebook
social network platform have important practical significance. Since the
information users share on social networks is often based on images, this paper
proposes a more secure image encryption algorithm based on Facebook social
network platform to ensure the loss of information as much as possible. When
the sender encrypts the image for uploading, it can first resist the third
party's attack on the encrypted image and prevent the image data from leaking,
simultaneously processed by some unknown processing such as compression and
filtering of the image on the Facebook platform, the receiver can still decrypt
the corresponding image data.
