Abstract:
Methods, non-transitory computer readable media and apparatuses for decrypting an image are disclosed. For example, a method captures a portion of an encrypted image and decrypts the portion of the image using a decryption key. The portion of the image contains partial information for an adjacent portion of the image. The method then displays the portion of the image that is decrypted and also displays the adjacent portion of the image using the partial information for the adjacent portion of the image. Another method includes capturing a first portion of an image that is encrypted using a first key and a second key, decrypting the first portion of the image using a first key and displaying the first portion of the image that is decrypted.
