Problems solved by technology

Although these image processing software can improve the display quality of photos, enrich people's lives and facilitate people's work, but in some specific cases, typically, when it is necessary to strictly ensure the authenticity of pictures, it will bring some troubles to people.
For example, a user provides a photo as evidence of a traffic violation scene, but there is no guarantee that the shooting time recorded on the photo must be the exact time of the traffic violation moment, because the current image processing technology can easily modify the photo taken time, and even the content of photos can be completely modified

Abstract

The embodiment of the invention discloses a password adding method and device, and a password photo processing method and device. The password adding method includes: encrypting the photo attribute information into a password according to a predetermined encryption algorithm; adding the password to the photo corresponding to the photo attribute information to generate a password photo. The password photo processing method includes: according to a predetermined decryption algorithm, obtaining the photo attribute information corresponding to the password in the password photo; according to the photo attribute information, determining the original reference information corresponding to the password photo. The invention solves the technical problem that the authenticity of the photo cannot be determined in the prior art, optimizes the existing digital shooting and image editing technology, and can realize the authenticity verification of the digital photo by obtaining the original reference information contained in the encrypted photo.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic technology, and in particular, to a method and device for adding a password, and a method and device for processing a password photo. Background technique [0002] With the continuous development of electronic technology, digital cameras have penetrated into thousands of households and become an essential tool for everyone to record beautiful natural scenery and engrave wonderful moments in life. Photos taken by digital cameras are called digital photos, which can be conveniently stored in various electronic devices. [0003] Along with the emergence of various image processing software (such as Photoshop or Meitu Xiuxiu, etc.), it becomes very simple for people to edit, modify or synthesize digital photos. Although these image processing software can improve the display quality of photos, enrich people's lives and facilitate people's work, but in some specific cases, typically...
