Electronic device and method for extracting encrypted message

摘要

A method of an electronic device is provided. The method includes generating a key code by receiving a selection on at least one area from among areas of an image displayed, decrypting an encrypted message included in the image by using the generated key code, and determining whether to output the encrypted message by determining whether a hash code for the decrypted message is identical to a hash code for inputted text information.

1. A method in an electronic device, the method comprising:
displaying a first image including a first encrypted message and a first hash code; receiving a selection of at least two areas from among a plurality of areas of the displayed first image; reading coordinate values corresponding to the selected at least two areas; generating a first key code for decrypting the first encrypted message based on the coordinate values corresponding to the selected at least two areas and a selected order of the selected at least two areas; decrypting the first encrypted message by using the first key code; generating a second hash code for the decrypted message; and determining whether to output the decrypted message by determining whether the second hash code is identical to the first hash code.
