Abstract
A method for encrypting an image, a method for transmitting an image, an electronic device, and a computer readable storage medium are provided. The method for encrypting an image includes steps of extracting an outline of an original image to obtain a binarized outline image and dividing the original image into a first image and a second image based on the binarized outline image. The second image comprises at least one encrypted region of the original image, and the first image comprises the remaining region of the original image other than the at least one encrypted region, the remaining region being an unencrypted region.

A method for encrypting an image, comprising steps of
- extracting an outline of an original image to obtain a binarized outline image;
- and
- dividing the original image into a first image and a second image based on the binarized outline image, wherein the second image comprises at least one encrypted region of the original image, the first image comprises the remaining region of the original image other than the at least one encrypted region, and the remaining region is an unencrypted region.
A method for transmitting an image, comprising steps of
- transmitting, by a first device, a GIF image to a second device, wherein the GIF image comprises a first image and a second image, the second image comprises at least one encrypted region of an original image, the first image comprises the remaining region of the original image other than the at least one encrypted region, and the remaining region is an unencrypted region;
- receiving, by the second device, the GIF image transmitted from the first device;
- and
- restoring the original image from the GIF image by the second device.
A method for transmitting an image, comprising steps of
- extracting, by a first device, an outline of an original image to obtain a binarized outline image;
- dividing, by the first device, the original image into a first image and a second image, based on the binarized outline image, wherein the second image comprises at least one encrypted region of the original image, the first image comprises the remaining region of the original image other than the at least one encrypted region, and the remaining region is an unencrypted region;
- storing, by the first device, the first image and the second image as different frames of a same GIF image;
- receiving, by the first device, an original image obtaining request generated by a second device based on a trigger event;
- obtaining, by the first device, a GIF file corresponding to the original image obtaining request;
- and
- sending, by the first device, the GIF file to the second device.
