Abstract:
A sharing method of a WiFi password, comprising: generating, on the basis of a pre-shared password acquired, a password watermark image corresponding to the pre-shared password (S10); inserting, on the basis of a carrier image acquired, the password watermark image into the carrier image to form a watermark carrier image (S20); sharing and transmitting the watermark carrier image to a shared terminal (S30); extracting, on the basis of the watermark carrier image received, password watermark information from the watermark carrier image (S40); and identifying, on the basis of the password watermark information extracted, a shared password from the password watermark information (S60). The method utilizes a watermark algorithm to insert the pre-shared password into an image, allowing active control over a sharing time and a sharing target. The invention further improves the confidentiality of a WiFi password during the sharing process.
