Description
Technical Field
The invention relates to the field of information security, in particular to a method and a system for authenticating the security of a trusted digital badge.
Background
The information hiding technology appears as a branch of the information security technology for over ten years, and the creation of the information hiding technology mainly aims to solve the problems that the digital information transmission quantity is rapidly increased under the condition of high-speed development of computer network technology, the accompanying security guarantee of a large number of digital files transmitted through a network is easily tampered, and various illegal purposes are transmitted and used. With the research and expansion, the information hiding technology can hide the information of the actually existing information by 18, so that the information hiding technology can be used for commercial application such as copyright protection and the like, can also be used for identifying an author, an issuer, a proprietor, a user and the like, and can identify illegally copied and stolen digital information products (digital watermarks) because of carrying copyright protection information and identity authentication information. The information hiding mainly comprises two major branches of digital watermarking and steganography. Digital watermarking is mainly intended to protect intellectual property rights and it verifies ownership of the media by embedding information in the original media data. Steganography is a means of secret communication, and the security of secret communication is obtained by hiding the existence of secret information. The purpose of steganography is to protect covert information that is hidden in a carrier. The impact of such information on the host media is not sufficient to attract attention and with certain recovery methods, the information should be invisible and imperceptible to an illegitimate recipient. Therefore, the unique use of the information hiding technology can be exerted by combining the technical use and characteristics of digital watermarking and steganography.
Software-as-a-Service (SaaS) is a completely innovative Software application model that started to emerge in the 21 st century with the development of internet technology and the maturity of application Software. The software needs to meet the respective requirements of multiple tenants and needs to be customized by the SaaS. The traditional software customization service is completed in a software development stage, and SaaS needs to be updated and customized according to the change of requirements in the software using process, and the use of other users cannot be influenced during the customization.
Cloud computing (cloud computing) is one type of distributed computing, and means that a huge data computing processing program is decomposed into countless small programs through a network "cloud", and then the small programs are processed and analyzed through a system consisting of a plurality of servers to obtain results and are returned to a user. In the early stage of cloud computing, simple distributed computing is adopted, task distribution is solved, and computing results are merged. Thus, cloud computing is also known as grid computing. By this technique, tens of thousands of data can be processed in a short time (several seconds), thereby achieving a strong network service.
At present, the application of information hiding technology mainly includes two aspects, on one hand, the digital watermarking technology is adopted and mainly used for protecting digital images, texts, videos and the like, and the digital watermarking technology also directly acts on protected object files, so that the effect of realizing the 'explicit visibility' is realized, therefore, the protection strength plays a more role in 'declarative' protection, and the application is more concentrated in the fields of commercial copyright protection and the like; and the steganography technology is adopted and mainly used for protecting digital images, texts and the like, and the steganography technology directly or indirectly acts on the protected object file to achieve the effect of 'invisibility and invisibility', so that the protection strength plays more roles in 'verifiability' protection, and the application is more concentrated in the fields of judicial evidence, safety and the like.
Therefore, the technology and the application of the two aspects of the information hiding technology have obvious differences, and the technology fusion in the specific application is not sufficient, so that the application requirements of a wider range and more convenience are difficult to adapt; moreover, the SaaS platform and the cloud computing service technology are relatively mature, but the combination of the information hiding technology, the SaaS platform and the cloud computing service technology is rarely seen, so that the information hiding platform service is lacked at present; in addition, most of the existing information hiding technologies are single isolated applications for specific file objects, so that the platform diversification application based on the SaaS and cloud computing service is difficult to support.
