Background
Currently, the closest prior art: in recent years, with the increasing awareness of right-keeping, society has been keenly calling for the protection of intellectual property rights of pictures. The block chain is a novel decentralized, transparent and non-falsifiable data storage structure, and plays an important role in the intellectual property protection work. In China, image intellectual property protection platforms based on block chain technology have emerged, but most of the block chain platforms have three problems: (1) is not reliable enough. Most platforms require users to upload pictures to a platform database and link picture information, so that the users cannot obtain trust. (2) It is not convenient enough. The notarization process of pictures is too complicated, and in daily life, if the ownership of the pictures shot by the mobile phone needs to be protected, the pictures need to be copied to a computer and then are subjected to a series of operations. (3) Not sufficiently concealed. Most of platforms only store picture information and print visible watermarks to finish marking, but the occurrence of infringement cannot be effectively prevented, the attractiveness of pictures is influenced, the attention of potential infringers is easily attracted, the watermarks are maliciously cut off, and the difficulty in protecting intellectual property rights is increased.
In summary, the problems of the prior art are:
(1) the existing block chain platform needs a user to upload a picture to a platform database and chain picture information, so that the trust of the user cannot be obtained.
(2) The existing block chain platform has a complicated picture notarization process.
(3) Most of the existing block chain platforms only store picture information and print visible watermarks to finish marking, so that the occurrence of infringement behaviors cannot be effectively prevented, the watermarks are maliciously cut off, and the difficulty in protecting intellectual property rights is increased.
The difficulty of solving the technical problems is as follows: the key of protecting the intellectual property of the picture lies in how to ensure that the picture can be reliably stored and authorized under various conditions, and simultaneously, the convenience of operation and the reliability of the platform are improved as much as possible. The difficulty to solve the above problems lies in how to get an optimal balance point between security and convenience, so that the user can conveniently complete the image storage and authentication tasks on the premise of feeling reassurance.
